+ + + + + + + Overview + + XEmbed is a protocol that uses basic X mechanisms such as client + messages and reparenting windows to provide embedding of a + control from one application into another application. Some + of the goals of the XEmbed design are: + + + + + Support for out-of process controls, written in any toolkit + or even plain Xlib. + + + + + Support for in-process-controls when mixing different + toolkits in one process. + + + + + Smooth integration of the embedding application and embedded client + in areas such as input device handling and visual feedback. + + + + + Easy implementation. A full implementation supporting all + details correctly may require minor toolkit modifications, + but it should be possible to get basic functionality going + in less than 1000 lines of code. + + + + + Goal 1 is the most urgent one. A embedding specification allows + developers to write applets for whatever desktop the user is + using in whatever toolkit they prefer. Goal 2 is more of + something to keep in mind than a immediate requirement. While + there are other ways to mix two or more toolkits, using XEmbed + might be the easiest and thus most comfortable way. Goal 3 + describes the targeted level of integration. The users should + not necessarily notice that they work with embedded controls; + devices like the keyboard and the mouse should work as expected, + inactive windows should look like they are inactive, and so + forth. The level of integration may, however, be limited by goal + 4. In order for the protocol to be successful, it's crucial to + get implementations for the most important toolkits. Thus, the + implementation should not require too much coding and no or only + few modifications to the toolkit's kernel. + + + At the time of writing, an implementation of XEmbed is included + in GTK+-2.0 that mostly conforms to this version of the + specification. The main area of divergence is in the area of + accelerators, where a simpler scheme is implemented than the + XEMBED_REGISTER_ACCELERATOR, XEMBED_UNREGISTER_ACCELERATOR + accelerator scheme described here. The KDE libraries (libkdeui) + include QXEmbed, a mostly-complete implementation for Qt of an + earlier version of the protocol. + + + + Definitions + + + Active + + + A toplevel window is active if it + currently is receiving keyboard events. (The window or a + descendent has the X keyboard focus.) A widget within the + toplevel is active if the toplevel is active, regardless + of whether that widget has the input focus within the + toplevel. + + + + + Client + + + In an embedding situation, the client is + the window that is embedded into an embedder. Sometimes also + called a plug. (Note that the usage here should not be + confused with the typical X usage of "client" to mean an application + connecting to the X server. That is always referred to as + an application in this document) + + + [ Should we replace client by some other term in + this document to avoid the confusion? ] + + + + + Embedder + + + In an embedding situation, the embedder + is the graphical location that embeds an external + client. Sometimes also called a socket or site. + + + + + Focused + + + A widget is focused if it receives + keyboard events within its toplevel. This is without + regard to whether the toplevel is active, and has nothing + to do with the X keyboard focus. + + + + + + + Rationale and discussion + + The basis for handling embedding is that the embedder acts like + a "window manager" for the client. (The window management + protocol is defined in the X Inter-Client Communications Manual + or ICCCM). The embedder selects with SubstructureRedirectMask + on its window so that it can intercept, and then the client + window is reparented (using + XReparentWindow()) + as a child of the embedder window. Because of the substructure redirect, the + embedder is able to intercept calls to move or resize the client + window, and handle them as appropriate to the location in the + embedding application. (Map requests are also redirected, but + XEmbed actually handles map requests separately... see the + description of the XEMBED_MAPPED flag.) + + + The window management protocol is sufficient to handle the + basics of visual embedding, but has deficiencies in other areas + that prevent it from providing natural integration between + toolkits. These areas include: + + + + window activation state + keyboard focus + tab focus chain + keyboard short cuts / accelerators + modality + drag and drop (XDND) + + + + The XEmbed protocol is mainly concerned with communicating + additional information between embedder and client to handle + these areas. Communication in XEmbed is done by forwarding + slightly modified XEvents using + XSendEvent(), + by sending special xembed messages, and by setting X properties. In addition, + standard ICCCM features like WMNormalHints are used where + appropriate. + + + The next sections explain why these problems occur with the + simple "window management" approach and how XEmbed solves them. + + + + Window activation state + + A widget has to know the activation state of its toplevel + window. This enables input widgets like a line editor, to display + a blinking cursor only when the user can actually type into it. In + addition, certain GUI styles choose to display inactive windows + differently, typically with a lighter and less contrasting color + palette. + + + Unfortunately, there are no such messages like WindowActivate + or WindowDeactivate in the X protocol. Instead, a window knows + that it is active when it receives keyboard focus (XFocusInEvent + with certain modes) or looses it (XFocusOutEvent with certain + modes). This applies to embedded child windows only, when the + mouse pointer points onto one of the child's subwindows in the very + moment the window manager puts the X focus on the toplevel + window. For that reason, XEmbed requires the embedders to pass + XEMBED_WINDOW_ACTIVATE and XEMBED_WINDOW_DEACTIVATE messages to + their respective clients whenever they get or loose X keyboard + + + + + Keyboard focus + + The delivery of keyboard events in X is designed in a way that + does not correspond to the typical operation of modern + toolkits; instead it seems designed to allow things to allow + things to work without either a window manager or a focus + handling in the toolkit. Typically, key events are sent to the + window which has the X input focus (set with + XSetInputFocus()). However, if the mouse pointer is inside + that focus window, the event is sent to the subwindow of the + focus window that is under the moues pointer. In modern toolkits, + the X input focus is typically left on the toplevel window and + a separate logical input focus is implemented within the + toolkit. The toolkit ignores the window that the key event is + actually sent to (which might be a scrollbar or other random + widget within the toplevel, depending on where the mouse + pointer is), and distributes key events to widget with the + logical input focus. + + + So, for standard operation, the behavior where key events are sent + to the window with the mouse pointer is simply ignored. But + with embedded windows, it causes problems, since, if the + mouse pointer is within the embedded window, the outer toolkit + doesn't see any key events, even if the logical keyboard focus + is elsewhere within the outer toolkits toplevel window. + + + Previous embedding techniques therefore required clients to + forward any key event they receive (KeyPress and KeyRelease) to + their respective embedder. In order to support multiple levels of + embedding, events that stem from a SendEvent request had to be + forwarded as well. While this is a possible solution, it adds both + race conditions and inefficency + + + The solution proposed by XEmbed is is to beat X11 with its own + weapons: The topmost toolkit is required + to keep the X input focus on one of its own windows without + any embedded children. Keeping the focus on such a window + ensures that key events are always delivered to the outer + toolkit and thus can be forwarded easily to any embedded + window. This also makes it possible to use this part of XEmbed + with clients that do not support the protocol at all, without + breaking keyboard input for the embedding application. + + + In detail, the topmost embedder creates a not-visible X Window to + hold the focus, the focus proxy. (It might be a 1x1 child + window of toplevel located at -1,-1.) Since the focus proxy isn't + an ancestor of the client window, the X focus can never move + into the client window because of the mouse pointer location. + In other words, whenever the outer window is activated + (receives the X input focus), it has to put the X focus on the + FocusProxy by calling XSetInputFocus(). + + + The trouble with this is, that you should not use XSetInputFocus() + without a proper time stamp from the Server, to avoid race + conditions. Unfortunately, the XFocusIn even does not carry a + timestamp. The solution to this is, to ask the window manager for + the WM_TAKE_FOCUS window protocol. Thus, whenever the window is + activated, it will receive a WM_PROTOCOLS client message with + data.l[0] being WM_TAKE_FOCUS and data.l[1] being a proper + timestamp. This timestamp can be used safely for the call to + XSetInputFocus(). + + + If an embedder widget gets the logical input focus, it sends + an XEMBED_FOCUS_IN message to its client. The client that + receives this messages knows that its logical focus is now + also the logical focus of the application window and will + react accordingly. If its logical focus lies on the line + editor control mentioned above, and the window is active, the + editor will show a blinking cursor after processing this + message. + + + In a similar fashion, if the embedder looses focus, it sends + an XEMBED_FOCUS_OUT message. + + + + Tab focus chain + + X does not have a concept of a tab focus chain, it is up to the + toolkit or the application to implement it. Since the concept + is standard among almost all toolkits, XEmbed supports it. An + XEmbed client integrates perfectly in the embedder's tab focus + chain, i.e. the user can tab onto the client, through all its + widgets and back to the outer world without noticing that they + traversed an external window. + + + As explained in the previous section, an embedder sends an + XEMBED_FOCUS_IN message to its client when it gets focus. The + detail code of this message is per default 0, that is, + XEMBED_FOCUS_CURRENT. It indicates that the clients keeps its own + logical focus where it was. To support tabbing, XEmbed provides + two more detail codes, namely XEMBED_FOCUS_FIRST and + XEMBED_FOCUS_LAST, that indicate that the client should move + its focus to the beginning or end of the focus chain. + + + When the user tabs to the very end of a client's tab chain, the + client follows the request (i.e. it puts its logical focus back to + the beginning its tab chain) and sends an XEMBED_FOCUS_NEXT + message to the embedder. If the embedder has siblings that accept + tab focus, it will do a virtual tab forward. As a result, it will + loose focus itself and consequently send an XEMBED_FOCUS_OUT + message to the client. As expected, the client's line edit control + from the previous example will stop blinking. + + + Backward tabbing is done exactly in the same manner, using the + XEMBED_FOCUS_PREV message. + + + + Keyboard short cuts / accelerators + + XEmbed is designed in such a way, that keyboard events are + received by the toplevel window, and then sent down the focus + focus chain. Toolkits will usually check for shortcuts or + accelerators before sending the event to the focus widget. If + such a shortcut is defined, the respective action is taken + rather than passing the event through to the focus + widget. This means, accelerators in the outmost window always + work properly, whereas accelerators defined inside an embedded + client only work if that client actually has focus. XEmbed + solves this problem with two messages, + XEMBED_REGISTER_ACCELERATOR and XEMBED_UNREGISTER_ACCELERATOR. + With XEMBED_REGISTER_ACCELERATOR, a client can reserve a + certain key/modifier combination as shortcut or + accelerator. The message is passed through to the topmost + embedder, where the key combination is stored. An + XEMBED_UNREGISTER_ACCELERATOR message releases the key again. + + + + Modality + + If an application window is shadowed by a modal dialog, no user + input is supposed to get through. The XEmbed design ensures this + for keyboard input, because the toplevel window knows about its + modal state and will not pass key events through. Embedded clients + thus inherit the modality from the topmost embedder. Mouse input, + however, is sent directly to the embedded clients by the X-Server, + unaffected by the modality of the application window. To give + clients the possibility to behave correctly when being shadowed by + a modal dialog, an embedder can choose to send an + XEMBED_MODALITY_ON message to its client when it becomes shadowed, + and an XEMBED_MODALITY_OFF message when it leaves modality + again. If the client contains embedders itself, those have to pass + both messages through to their clients. + + + + Drag and drop (XDND) + + XDND drag-and-drop does not work with reparented external + windows, since messages are exchanged with the toplevel window + only. This is done for performance reasons. While it is cheap to + get the window under the mouse pointer, it is very expensive to + get a window under another window. Unfortunately, this is required + quite often when dragging objects around, since the pointer + may overlap the drag icon. + + + Solving the drag-and-drop problem, however, is quite easy, + since the XDND protocol was carefully designed in a way that + makes it possible to support embedded windows. Basically, the + embedder has to operate as drag-and-drop proxy for the client. Any + XDND messages like XdndEnter, Xdnd,Leave, etc. simply have to be + passed through. A toollkit's XDND implementation has to take this + situation in consideration. + + + + + Embedding life cycle + + The protocol is started by the embedder. The window ID of + the client window is passed (by unspecified means) to the + embedding application, and the embedder calls + XReparentWindow() to reparent the client + window into the embedder window. + + + Implementations may choose to support an alternate method of + beginning the protocol where the window ID of the embedder + is passed to client application and the client creates a window + within the embedder, or reparents an existing window into + the embedder's window. Which method of starting XEmbed is + used a matter up to higher level agreement and outside the + scope of this specification. + + + In either case the client window must have a property called + _XEMBED_INFO on it. This property has type _XEMBED_INFO + and format 32. The contents of the property are: + + + _XEMBED_INFO + + + + FieldTypeComments + + + + + versionCARD32The protocol version + + + flagsCARD32A bitfield of flags + + + +
+ + The version field indicates the + maximum version of the protocol that the client supports. + The embedder should retrieve this field and set the data2 field + of the XEMBED_EMBEDDED_NOTIFY to + Min (version, max version supported by embedder). + The version number corresponding to the current version of the + protocol is 0. + [Should the version be defined as (Major << 16 | Minor) ?] + + + The currently defined bit in the + flags field is: + + /* Flags for _XEMBED_INFO */ +#define XEMBED_MAPPED (1 << 0) + + + XEMBED_MAPPED + + + If set the client should be mapped. The embedder must + track the flags field by selecting for PropertyNotify + events on the client and map and unmap the client + appropriately. (The embedder can leave the client unmapped + when this bit is set, but should immediately unmap the + client upon detecting that the bit has been unset.) + + + Rationale: the reason for using this bit rather than + MapRequest events is so that the client can reliably + control it's map state before the inception of the + protocol without worry that the client window will + become visible as a child of the root window. + + + + + + To support future expansion, all fields not currently defined + must be set to zero. To add proprietary extensions to the + XEMBED protocol, an application must use a separate property, rather + than using unused bits in the struct field or extending the + _XEMBED_INFO property. + + + At the start of the protocol, the embedder first sends an + XEMBED_EMBEDDED_NOTIFY message, then sends + XEMBED_FOCUS_IN, XEMBED_WINDOW_ACTIVATE, and XEMBED_MODALITY_ON + messages as necessary to synchronize the state of the + client with that of the embedder. Before any of these messages + received, the state of the client is: + + Not focused + Not active + Modality off + + + + If the embedder is geometry managed and can change its size, it + should obey the client's WMNormalHints settings. Note that + most toolkits will not have equivalents for all the hints in + the WMNormalHints settings, clients must not assume that the + requested hints will be obeyed exactly. The + width_inc, + height_inc, + min_aspect, and + max_aspect fields are examples of + fields from WMNormalHints that are unlikely to be supported + by embedders. + + + The protocol ends in one of three ways: + + + + + The embedder can unmap the client and reparent the client + window to the root window. If the client receives an + ReparentNotify event, it should check the + parent field of the + XReparentEvent structure. If this + is the root window of the window's screen, then the protocol + is finished and there is no further interaction. If it + is a window other than the root window, then the protocol + continues with the new parent acting as the embedder window. + + + + + The client can reparent its window out of the embedder + window. If the embedder receives a ReparentNotify signal + with the window field being the + current client and the parent + field being a different window, this indicates the end + of the protocol. + + + [ GTK+ doesn't currently handle this; but it seems useful + to allow the protocol to be ended in a non-destructive + fashion from either end. ] + + + + + The client can destroy its window. + + + + + + Message Specifications + + An XEmbed message is an X11 client message with message type + "_XEMBED". The format is 32, the first three data longs carry the + toolkit's X time (l[0]), the message's major opcode (l[1]) and the + message's detail code (l[2]). If no detail is required, the value + passed has to be 0. The remaining two data longs (l[3] and l[4]) + are reserved for data1 and data2. Unused bytes of the client + message are set to 0. The event is sent to the target window with + no event mask and propagation turned off. + + + The valid XEmbed messages are: + + /* XEMBED messages */ +#define XEMBED_EMBEDDED_NOTIFY 0 +#define XEMBED_WINDOW_ACTIVATE 1 +#define XEMBED_WINDOW_DEACTIVATE 2 +#define XEMBED_REQUEST_FOCUS 3 +#define XEMBED_FOCUS_IN 4 +#define XEMBED_FOCUS_OUT 5 +#define XEMBED_FOCUS_NEXT 6 +#define XEMBED_FOCUS_PREV 7 +/* 8-9 were used for XEMBED_GRAB_KEY/XEMBED_UNGRAB_KEY */ +#define XEMBED_MODALITY_ON 10 +#define XEMBED_MODALITY_OFF 11 +#define XEMBED_REGISTER_ACCELERATOR 12 +#define XEMBED_UNREGISTER_ACCELERATOR 13 +#define XEMBED_ACTIVATE_ACCELERATOR 14 + + A detail code is required for XEMBED_FOCUS_IN.

A client that + receives this messages knows that its window was embedded by an + XEmbed site and not simply reparented by a window manager. To support toolkits + that do not keep track of reparenting events, the message carries + the embedder's window handle as data1: + + + XEMBED_EMBEDDED_NOTIFY + + + + data1The embedder's window handle. + + + data2The protocol version in use + (see the description of _XEMBED_INFO). + + + +
+ + + XEMBED_WINDOW_ACTIVATE / XEMBED_WINDOW_DEACTIVATE + + Sent from the embedder to the client when the window becomes + active or inactive, i.e. when the window gets or looses the + keyboard input focus. If the client contains embedders itself, + those have to pass the message through to their clients. + + + Note that no XEMBED_FOCUS_IN or XEMBED_FOCUS_OUT messages + should be sent when the toplevel window gains or loses + focus. The XEMBED_FOCUS_IN and XEMBED_FOCUS_OUT messages + refer only to focus within the + toplevel window and are independent of toplevel activation + state. This independence is necessary so that input focus + within a toplevel can be moved programmatically when the + toplevel doesn't have input focus. + + + [ GTK+ is currently in violation of the preceding note, + and sends FOCUS_IN and FOCUS_OUT only when the toplevel + is active. See + GNOME bug #67943 ] + + + Widgets within the client should typically be displayed with + the focus only when the client both has focus and is active. + + + + XEMBED_REQUEST_FOCUS + + Sent from the client to the embedder when the client wants + focus. The most common ocassion is when the user clicks into one + of the client's child widgets, for example a line editor, in order + to type something in. + + + The message is passed along to the topmost embedder that + eventually responds with a XEMBED_FOCUS_IN message. The focus in + message is passed all the way back until it reaches the original + focus requestor. In the end, not only the original client has + focus, but also all its ancestor embedders. + + + + XEMBED_FOCUS_IN + + Sent from the embedder to the client when it gets focus. The + detail code determines, where the client shall move its own + logical focus to. Three possibilities exist: + + + + XEMBED_FOCUS_CURRENT + + + Normal activation, does not move the clients logical + focus. + + + + + XEMBED_FOCUS_FIRST + + + Used when the user tabs onto a client. It indicates that + the client should put its logical focus onto the widget + that comes first in its own tab focus chain. + + + + + XEMBED_FOCUS_LIST + + + Used when the user tabs onto a client. It indicates that + the client should put its logical focus onto the widget + that comes first in its own tab focus chain. + + + + + + + XEMBED_FOCUS_OUT + + Sent from the embedder to the client when it looses focus. + + + + XEMBED_FOCUS_NEXT + + Sent from the client to the embedder when it reaches the end of + its logical tab chain after the user tabbed forwards. If the + embedder has siblings that accept tab focus, it will do a virtual + tab forward. As a result, it will loose focus itself and + consequently send an XEMBED_FOCUS_OUT message to the client + + + + XEMBED_FOCUS_PREV + + Sent from the client to the embedder when it reaches the + beginning of its logical tab chain after the user tabbed + backwards. If the embedder has siblings that accept tab focus, it + will do a virtual tab backward. As a result, it will loose focus + itself and consequently send an XEMBED_FOCUS_OUT message to the + client + + + + XEMBED_REGISTER_ACCELERATOR / XEMBED_UNREGISTER_ACCELERATOR + + A client that needs to reserve a certain key/modifier + combination as shortcut or accelerators, sends a XEMBED_REGISTER_ACCELERATOR + message to its embedder. As long as the embedder itself is a child + of a client, the accelerator will be propagated up to the toplevel. + + + XEMBED_REGISTER_ACCELERATOR + + + + detailaccelerator_id + + + data1X key symbol + + + data2bit field of modifier values + + + +
+ + The accelerator_id is used to identify the accelerator when + activating the accelerator. The reason for using an + accelerator ID instead of identifying accelerators simply by + key symbol and modifiers is to allow the correct handling of + overloaded accelerators with embedded widgets. (An accelerator + is overloaded if there multiple accelerators on the same key, + usually because of accidental collisions.) When an overloaded + accelerator is pressed repeatedly, the toplevel activates + accelerators on that key in round-robin fashion. If this + round-robin behavior is not supported by the embedding + toolkit, picking an arbitrary accelerator for the key and + activating it is acceptable. Well designed applications should + avoid collisions in any case. + + + + Ordering the round-robin of conflicting accelerators + in a predictable (geometric or in focus chain) order + is desirable. This can be achieved if the toplevel sorts + the conflicting accelerators as if they applied to the + client instead of widgets within the client and then + each client does the same sort on the subset of conflicting + accelerators within it. To get this to work properly + if there are conflicting accelerators within a client, say widget + A and B both have the same mnemonic, then instead of + registering one accelerator for widget A and one for + widget B, the client should register two accelerators that + corresponds to both A and B, and then when + XEMBED_ACTIVATE_ACCELERATOR is received for either + accelerator, implement round robin between A and B + with the correct sorting. + + + + The modified bit field is a bitwise OR of values indicating + various accelerators; these indicate logical accelerator + keys rather than corresponding directly to the bits in + the XKeyEvent state field. + + /* Modifiers field for XEMBED_REGISTER_ACCELERATOR */ +#define XEMBED_MODIFIER_SHIFT (1 << 0) +#define XEMBED_MODIFIER_CONTROL (1 << 1) +#define XEMBED_MODIFIER_ALT (1 << 2) +#define XEMBED_MODIFIER_SUPER (1 << 3) +#define XEMBED_MODIFIER_HYPER (1 << 4) + + (Meta is intentionally left out here because if you try to separate + Alt and Meta, a large fraction of users will experience problems + with their keyboard setups... there is no reliably standard + of which one is the primary modifier key and on the Alt key.) + + + On activation, the topmost embedder will send + XEMBED_ACTIVATE_ACCELERATOR to its client; if the + accelerator was registered by an embedder inside that + client, the embedder will send XEMBED_ACTIVATE_ACCELERATOR + to its client and so forth. + + + Note that the assignment of ID's is private for each pair + of client and embedder and when accelerators are being + propagated through multiple client/embedder pairs, a + different accelerator ID may be used for each pair. + + + The XEMBED_UNREGISTER_ACCELERATOR message releases the key + combination again. + + + XEMBED_UNREGISTER_ACCELERATOR + + + + detailinteger ID passed + to XEMBED_REGISTER_ACCELERATOR + + + +
+ + Hint to implementators: It is the responsibility of the + embedder to keep track of all forwarded accelerators + and to remove them when the client window dies. + + + + XEMBED_ACTIVATE_ACCELERATOR + + The XEMBED_ACTIVATE_ACCELERATOR message is sent when a + accelerator previously registered with + XEMBED_REGISTER_ACCELERATOR is activated on the toplevel + containing the embedder. + + + XEMBED_ACTIVATE_ACCELERATOR + + + + detailinteger ID passed + when registering the accelerator + + + data1flags. + + + +
+ + The following bit is defined for the flags field; all + other bits must be zero. + + /* Flags for XEMBED_ACTIVATE_ACCELERATOR */ +#define XEMBED_ACCELERATOR_OVERLOADED (1 << 0) + + + + XEMBED_ACCELERATOR_OVERLOADED + + + This flag indicates that multiple accelerators exist for + the key combination within the toplevel. The toolkit + may modify the behavior of the accelerator based on + this value. For instance, if the accelerator is a + mnemonic for a button, it might activate the the button + immediately if the accelerator is not overloaded, but + when overloaded, it would only focus the button. + + + + + + + XEMBED_MODALITY_ON / XEMBED_MODALITY_OFF + + Sent from the embedder to the client when the window becomes + shadowed by a modal dialog, or when it is released again. If the + client contains embedders itself, those have to pass the message + through to their clients. An embedded control should ignore + mouse input while modality is active. Note that that keyboard + input is blocked anyway by XEmbed, since the topmost embedder will + not pass keyboard events through in modal state. + + + + + + Techniques + + + Handling errors + + Implementors of the XEmbed protocol should handle the other + party disappearing at any point. For this reason X errors + must be trapped when performing any operation with a window + not created by the application. This is done by using + XSetErrorHandler(). + A sample implementation of trapping errors in C looks like: + + #include <X11/Xlib.h> + +static int trapped_error_code = 0; +static int (*old_error_handler) (Display *, XErrorEvent *); + +static int +error_handler(Display *display, + XErrorEvent *error) +{ + trapped_error_code = error->error_code; + return 0; +} + +void +trap_errors(void) +{ + trapped_error_code = 0; + old_error_handler = XSetErrorHandler(error_handler); +} + +int +untrap_errors(void) +{ + XSetErrorHandler(old_error_handler); + return trapped_error_code; +} + + + Forwarding X Events + + An XEmbed embedder has to forward key-press and key-release + events to its respective client. + + + Key events are forwarded by changing the event's window field + to the window handle of the client and sending the modifed + message via XSendEvent() to the embedder, + with no event mask and propagation turned off. + + + Note: XEmbed requires toolkits to handle key-events that come + from a SendEvent request. That means, if somebody can access + your X-Server, it's possible to fake keyboard input. Given + that most toolkits accept sent key events today anyway and the + X Server is typically protected through magic cookie + authorization, this is not considered to be an + issue. Applications with higher security requirements may + choose not to use embedded components, though, and to filter + out any events coming from XSendEvent(). + + + Given that Window client is the client's window handle, + here is a piece of code of an imaginary event-loop in C that does + the forwarding. + + #include <X11/Xlib.h> + +void handle_event( + Display* dpy, /* display */ + XEvent* ev /* event */ +){ + if ( ev->type == KeyPress || ev->type == KeyRelease ) { + ev->xkey.window = client; + trap_errors(); + XSendEvent( dpy, client, False, NoEventMask, ev ); + XSync( dpy, False ); + if (untrap_errors()) { + /* Handle failure */ + } + + return; + } + ... /* normal event handling */ +} + + + Sending XEmbed messages + + Given that Time x_time contains the timestamp from the event + currently being processed. (CurrentTime is generally the best + choice if no event is being processed), here is a valid + implementation in C of sending an XEMBED message: + + #include <X11/Xlib.h> + +void send_xembed_message( + Display* dpy, /* display */ + Window w, /* receiver */ + long message, /* message opcode */ + long detail /* message detail */ + long data1 /* message data 1 */ + long data2 /* message data 2 */ +){ + XEvent ev; + memset(&ev, 0, sizeof(ev)); + ev.xclient.type = ClientMessage; + ev.xclient.window = w; + ev.xclient.message_type = XInternAtom( dpy, "_XEMBED", False ); + ev.xclient.format = 32; + ev.xclient.data.l[0] = x_time; + ev.xclient.data.l[1] = message; + ev.xclient.data.l[2] = detail; + ev.xclient.data.l[3] = data1; + ev.xclient.data.l[4] = data2; + trap_errors(); + XSendEvent(dpy, w, False, NoEventMask, &ev); + XSync(dpy, False); + if (untrap_errors()) { + /* Handle failure */ + } +} + + + + Issues + + Implementation of modality + + The protocol could be simplified by removing the + XEMBED_MODALITY_ON and XEMBED_MODALITY_OFF messages in favor + of requiring the embedder to map an input-only window over + it's child when it beings shadowed by a modal grab. + + + One possible reason for the current protocol is that a toolkit + might want to have elements such as scrollbars that remain + active even when grab shadowed. (I know of no toolkit that + actually implements this.) + + + + Clarify function of timestamps + + The function of the timestamp arguments needs to be clarified, + as well as the requirements for what should be passed + in the field. The original draft of the specification + contained the text about the determining the timestamp. + +
+ + The x time is to be updated whenever the toolkit receives an + event from the server that carries a timestamp. XEmbed client + messages qualify for that. + + + Hint to implementators: Check that the xembed time stamp + is actually later than your current x time. While this cannot + happen with ordinary XEvents, delayed client messages may have + this effect. Be prepared that evil implementations may even + pass CurrentTime sometimes. + +
+ + But I [OWT] wouldn't agree with this advice. The point + of a timestamp is to make sure that when events are processed + out of order, the event generated last by the user wins + for shared resources such as input focus, selections, and + grabs. An example of where this can matter is if you have + + Toplevel Window + Embedder + Client + Text Entry 1 + Embedder + Client + Text Entry 2 + + If the entries are set to select the text on focus in, and the + user hits TAB in quick succession, then the timestamps on the + FOCUS_IN events are what makes sure that Entry 2 actually ends + up owning the PRIMARY selection, instead of it being a race + between the two clients. But in situations like this having + the correct timestamp only matters if a user action triggers + the behavior. + + + Hence the advice that the timestamp should be the time from + the event currently being processed. + + + If no explicit user action is involved, then the + best thing to do is to use CurrentTime; using the timestamp + from the last X event received can cause problems if the + ultimate trigger of the behavior is a timeout or network + and the last X event happened some time in the distant past. + + + + Complexity of accelerator handling + + The current specification for accelerator handling is a little + complex. Most of the complexity (the accelerator IDs) comes + from the need to handle conflicting accelerators. + GTK+ currently implements a simpler scheme where grabs are + identified only by key symbol and modifier and conflicting + mnemonic resolution doesn't work across embedder/client + interfaces. + + + + Infinite loops in focusing + + There is the potential for infinite loops of focusing - + Consider the case: + + Toplevel Window + Embedder + Client + + Where there are no focusable sites in the client or in the + toplevel window. Then if Tab is pressed, the embedder + will send: FOCUS_IN/FOCUS_FIRST to the client, the client will + send FOCUS_NEXT to the embedder, the toplevel window will + wrap the focus around and send FOCUS_IN/FOCUS_FIRST to the + client... + + + The minimum mechanism that seems necessary to prevent this + loop is a serial number in the FOCUS_IN/FOCUS_FIRST message + that is repeated in a resulting FOCUS_NEXT message. + + + A possibly better way of handling this could be to make FOCUS_IN have + an explicit response; that, is, add a XEMBED_FOCUS_IN_RESPONSE + that the client must send to the embedder after receipt + of a FOCUS_IN message. + + + + XEMBED_FOCUS_IN_RESPONSE + + + + detail1 if the client accepted the focus, 0 otherwise + + + data1serial number from XEMBED_FOCUS_IN + + + +
+ + The main problem with requiring a response here is that caller + needs to wait for the return event, and to handle cases like + parent (client 1) => child (client 2) => grandchild (client 1), + it probably needs to process all sorts of incoming events at + this point. If the user hits TabTab + in quick succession things could get very complicated. + + + + Robustness + + The protocol, as currently constituted, is not robust against + the embedder crashing. This will result in the embedder + window being destroyed by the X server, and, as a consequence + client's window being unexpectedly destroyed, which will likely cause the + client to die with a BadWindow error. + + + To fix this requires an X protocol extension which extends + the functionality of XChangeSaveSet() in + two areas: + + + + + Allow it to be specified that the saved window should be + reparented to the root window rather than to the nearest + parent. (The nearest parent typically being the window + manager's frame window, reparenting to the nearest + parent only saves the client until the window manager + cleans up and destroys the frame window.) + + + + + Allow it to be specified that the saved window should be + unmapped rather than then mapped. (Without this capability + the client will mapped as a child of the root window, + which will be confusing to the user.) + + + + + + Sensitivity + + Toolkits such as Qt and GTK+ have a concept of disabled + widgets. This notion is typically hierarchical, so if + the embedder or a ancestory of the embedder becomes + insensitive, widgets inside the client should be displayed as, + and act insensitive as well. + + + + Directional focusing + + Some toolkits, such as GTK+, support, along with the standard + concept of a focus chain, the idea of directional + focusing; it's possible in some cases to navigate + focus using the arrow keys. To do this perfectly, you need + to have information about the coordinates of the original + focus window, which is hard to do in an embedding context, + but a good approximation is to, when focusing into a + container, provide the side of the container where focus + is coming from and to focus the "middle widget" on this side. + + + This could be supported by adding an extra data field to + to the XEMBED_FOCUS_FIRST/XEMBED_FOCUS_LAST subtypes + of XEMBED_FOCUS_IN and to XEMBED_FOCUS_NEXT and + XEMBED_FOCUS_PREV, which would contain: + + /* Directions for focusing */ +#define XEMBED_DIRECTION_DEFAULT 0 +#define XEMBED_DIRECTION_UP_DOWN 1 +#define XEMBED_DIRECTION_LEFT_RIGHT 2 + + Applications supporting only normal tab focusing would always + pass XEMBED_DIRECTION_DEFAULT and treat all received + directions as XEMBED_DIRECTION_DEFAULT. + + + The argument against supporting this is that it's a rather + confusing feature to start with (many widgets eat arrow keys + for other purposes), and becomes more confusing if you have + a application containing widgets from different toolkits, + some of which support it, some of which don't. + + + + Modal dialogs + + The specification doesn't have any provisions for handling the + case where an embedded client wants to put up a dialog. Such a + dialog should be transient-for the real toplevel window, and, + if modal, should block the entire toplevel window. To fully + implement this, you would need some concept of an application + that spanned multiple toplevel windows in multiple clients. + + + + Propagation of key presses + + It's frequently useful to have keybindings that trigger on + a widget if the focus is on a child of that widget. For + instance, ControlPageUp + and ControlPageUp switch + pages in a notebook widget when the focus is on a child + of the notebook. The XEmbed spec currently has no handling + of this situation. + + + The simplest solution would be to specify that if the client + widget doesn't handle a key press sent to it, it then sends + the event back to the embedder. Some care would be required + in the embedder handle infinite loops, but it shouldn't + be that bad. + + + + Handling of toplevel modes + + GTK+-2.0 contains a feature for key navigation of tooltips + where Control-F1 toggles a "tooltips keyboard mode" where + the tooltip for the currently focused window is displayed. + There is no way of propagating this across XEMBED. + This feature could clearly be implemented the same + way as XEMBED_WINDOW_ACTIVATE, but adding a pair of + messages for every feature of this type seems excessive. + + + A possible alternate idea would be to add a _XEMBED_STATE + property that the embedder sets on the client window which + is a list of atoms. This could actually be used to + replace XEMBED_WINDOW_ACTIVATE, and XEMBED_MODALITY_ON, + simplifying the protocol. + + + There are some race conditions in maintaining this property + if the client is allowed to reparent itself out of the + embedder that would have to be considered. + + + + + Change history + + "Version 1.0 DRAFT 1", 22 April 2000, Matthias Ettrich + + + + + "Version 1.0 DRAFT 2", 15 August 2000, Matthias Ettrich + + + + + Version 0.5, 19 April 2002, Owen Taylor + + + + + Add the life-cycle chapter, including _XEMBED_INFO + property, and the XEMBED_MAPPED flags. + + + + + Define the data2 for XEMBED_EMBEDDED_NOTIFY to be the + protocol version in use. + + + + + Replaced XEMBED_GRAB_KEY scheme for handling accelerators + with XEMBED_REGISTER_ACCELERATOR. + + + + + Removed text "This also means that the client has to + prepare for becoming visible anytime without filing a map + request itself" from the description of + XEMBED_EMBEDDED_NOTIFY". + + + + + Added text about the independence of FOCUS_IN/OUT and + ACTIVATE/DEACTIVE to the description of + XEMBED_WINDOW_ACTIVATE / XEMBED_WINDOW_DEACTIVATE. + + + + + Added note about fields in WMNormalHints not necessarily + being obeyed by embedders. + + + + + Removed mention of XEMBED_PROCESS_NEXT_EVENT, which is + no longer part of the protocol. + + + + + Added definitions of "Active" and "Focused" to the + definitions section. + + + + + Added issues and change history sections. + + + + + Lots of textual editing for clarity, style consistency. + + + + + Converted to docbook format. + + + + + + +

+ ettrich@trolltech.com +
+ + + + Owen + Taylor + +
+ otaylor@redhat.com +
+ + + + + + + Overview + + XEmbed is a protocol that uses basic X mechanisms such as client + messages and reparenting windows to provide embedding of a + control from one application into another application. Some + of the goals of the XEmbed design are: + + + + + Support for out-of process controls, written in any toolkit + or even plain Xlib. + + + + + Support for in-process-controls when mixing different + toolkits in one process. + + + + + Smooth integration of the embedding application and embedded client + in areas such as input device handling and visual feedback. + + + + + Easy implementation. A full implementation supporting all + details correctly may require minor toolkit modifications, + but it should be possible to get basic functionality going + in less than 1000 lines of code. + + + + + Goal 1 is the most urgent one. A embedding specification allows + developers to write applets for whatever desktop the user is + using in whatever toolkit they prefer. Goal 2 is more of + something to keep in mind than a immediate requirement. While + there are other ways to mix two or more toolkits, using XEmbed + might be the easiest and thus most comfortable way. Goal 3 + describes the targeted level of integration. The users should + not necessarily notice that they work with embedded controls; + devices like the keyboard and the mouse should work as expected, + inactive windows should look like they are inactive, and so + forth. The level of integration may, however, be limited by goal + 4. In order for the protocol to be successful, it's crucial to + get implementations for the most important toolkits. Thus, the + implementation should not require too much coding and no or only + few modifications to the toolkit's kernel. + + + At the time of writing, an implementation of XEmbed is included + in GTK+-2.0 that mostly conforms to this version of the + specification. The main area of divergence is in the area of + accelerators, where a simpler scheme is implemented than the + XEMBED_REGISTER_ACCELERATOR, XEMBED_UNREGISTER_ACCELERATOR + accelerator scheme described here. The KDE libraries (libkdeui) + include QXEmbed, a mostly-complete implementation for Qt of an + earlier version of the protocol. + + + + Definitions + + + Active + + + A toplevel window is active if it + currently is receiving keyboard events. (The window or a + descendent has the X keyboard focus.) A widget within the + toplevel is active if the toplevel is active, regardless + of whether that widget has the input focus within the + toplevel. + + + + + Client + + + In an embedding situation, the client is + the window that is embedded into an embedder. Sometimes also + called a plug. (Note that the usage here should not be + confused with the typical X usage of "client" to mean an application + connecting to the X server. That is always referred to as + an application in this document) + + + [ Should we replace client by some other term in + this document to avoid the confusion? ] + + + + + Embedder + + + In an embedding situation, the embedder + is the graphical location that embeds an external + client. Sometimes also called a socket or site. + + + + + Focused + + + A widget is focused if it receives + keyboard events within its toplevel. This is without + regard to whether the toplevel is active, and has nothing + to do with the X keyboard focus. + + + + + + + Rationale and discussion + + The basis for handling embedding is that the embedder acts like + a "window manager" for the client. (The window management + protocol is defined in the X Inter-Client Communications Manual + or ICCCM). The embedder selects with SubstructureRedirectMask + on its window so that it can intercept, and then the client + window is reparented (using + XReparentWindow()) + as a child of the embedder window. Because of the substructure redirect, the + embedder is able to intercept calls to move or resize the client + window, and handle them as appropriate to the location in the + embedding application. (Map requests are also redirected, but + XEmbed actually handles map requests separately... see the + description of the XEMBED_MAPPED flag.) + + + The window management protocol is sufficient to handle the + basics of visual embedding, but has deficiencies in other areas + that prevent it from providing natural integration between + toolkits. These areas include: + + + + window activation state + keyboard focus + tab focus chain + keyboard short cuts / accelerators + modality + drag and drop (XDND) + + + + The XEmbed protocol is mainly concerned with communicating + additional information between embedder and client to handle + these areas. Communication in XEmbed is done by forwarding + slightly modified XEvents using + XSendEvent(), + by sending special xembed messages, and by setting X properties. In addition, + standard ICCCM features like WMNormalHints are used where + appropriate. + + + The next sections explain why these problems occur with the + simple "window management" approach and how XEmbed solves them. + + + + Window activation state + + A widget has to know the activation state of its toplevel + window. This enables input widgets like a line editor, to display + a blinking cursor only when the user can actually type into it. In + addition, certain GUI styles choose to display inactive windows + differently, typically with a lighter and less contrasting color + palette. + + + Unfortunately, there are no such messages like WindowActivate + or WindowDeactivate in the X protocol. Instead, a window knows + that it is active when it receives keyboard focus (XFocusInEvent + with certain modes) or looses it (XFocusOutEvent with certain + modes). This applies to embedded child windows only, when the + mouse pointer points onto one of the child's subwindows in the very + moment the window manager puts the X focus on the toplevel + window. For that reason, XEmbed requires the embedders to pass + XEMBED_WINDOW_ACTIVATE and XEMBED_WINDOW_DEACTIVATE messages to + their respective clients whenever they get or loose X keyboard + + + + + Keyboard focus + + The delivery of keyboard events in X is designed in a way that + does not correspond to the typical operation of modern + toolkits; instead it seems designed to allow things to allow + things to work without either a window manager or a focus + handling in the toolkit. Typically, key events are sent to the + window which has the X input focus (set with + XSetInputFocus()). However, if the mouse pointer is inside + that focus window, the event is sent to the subwindow of the + focus window that is under the moues pointer. In modern toolkits, + the X input focus is typically left on the toplevel window and + a separate logical input focus is implemented within the + toolkit. The toolkit ignores the window that the key event is + actually sent to (which might be a scrollbar or other random + widget within the toplevel, depending on where the mouse + pointer is), and distributes key events to widget with the + logical input focus. + + + So, for standard operation, the behavior where key events are sent + to the window with the mouse pointer is simply ignored. But + with embedded windows, it causes problems, since, if the + mouse pointer is within the embedded window, the outer toolkit + doesn't see any key events, even if the logical keyboard focus + is elsewhere within the outer toolkits toplevel window. + + + Previous embedding techniques therefore required clients to + forward any key event they receive (KeyPress and KeyRelease) to + their respective embedder. In order to support multiple levels of + embedding, events that stem from a SendEvent request had to be + forwarded as well. While this is a possible solution, it adds both + race conditions and inefficency + + + The solution proposed by XEmbed is is to beat X11 with its own + weapons: The topmost toolkit is required + to keep the X input focus on one of its own windows without + any embedded children. Keeping the focus on such a window + ensures that key events are always delivered to the outer + toolkit and thus can be forwarded easily to any embedded + window. This also makes it possible to use this part of XEmbed + with clients that do not support the protocol at all, without + breaking keyboard input for the embedding application. + + + In detail, the topmost embedder creates a not-visible X Window to + hold the focus, the focus proxy. (It might be a 1x1 child + window of toplevel located at -1,-1.) Since the focus proxy isn't + an ancestor of the client window, the X focus can never move + into the client window because of the mouse pointer location. + In other words, whenever the outer window is activated + (receives the X input focus), it has to put the X focus on the + FocusProxy by calling XSetInputFocus(). + + + The trouble with this is, that you should not use XSetInputFocus() + without a proper time stamp from the Server, to avoid race + conditions. Unfortunately, the XFocusIn even does not carry a + timestamp. The solution to this is, to ask the window manager for + the WM_TAKE_FOCUS window protocol. Thus, whenever the window is + activated, it will receive a WM_PROTOCOLS client message with + data.l[0] being WM_TAKE_FOCUS and data.l[1] being a proper + timestamp. This timestamp can be used safely for the call to + XSetInputFocus(). + + + If an embedder widget gets the logical input focus, it sends + an XEMBED_FOCUS_IN message to its client. The client that + receives this messages knows that its logical focus is now + also the logical focus of the application window and will + react accordingly. If its logical focus lies on the line + editor control mentioned above, and the window is active, the + editor will show a blinking cursor after processing this + message. + + + In a similar fashion, if the embedder looses focus, it sends + an XEMBED_FOCUS_OUT message. + + + + Tab focus chain + + X does not have a concept of a tab focus chain, it is up to the + toolkit or the application to implement it. Since the concept + is standard among almost all toolkits, XEmbed supports it. An + XEmbed client integrates perfectly in the embedder's tab focus + chain, i.e. the user can tab onto the client, through all its + widgets and back to the outer world without noticing that they + traversed an external window. + + + As explained in the previous section, an embedder sends an + XEMBED_FOCUS_IN message to its client when it gets focus. The + detail code of this message is per default 0, that is, + XEMBED_FOCUS_CURRENT. It indicates that the clients keeps its own + logical focus where it was. To support tabbing, XEmbed provides + two more detail codes, namely XEMBED_FOCUS_FIRST and + XEMBED_FOCUS_LAST, that indicate that the client should move + its focus to the beginning or end of the focus chain. + + + When the user tabs to the very end of a client's tab chain, the + client follows the request (i.e. it puts its logical focus back to + the beginning its tab chain) and sends an XEMBED_FOCUS_NEXT + message to the embedder. If the embedder has siblings that accept + tab focus, it will do a virtual tab forward. As a result, it will + loose focus itself and consequently send an XEMBED_FOCUS_OUT + message to the client. As expected, the client's line edit control + from the previous example will stop blinking. + + + Backward tabbing is done exactly in the same manner, using the + XEMBED_FOCUS_PREV message. + + + + Keyboard short cuts / accelerators + + XEmbed is designed in such a way, that keyboard events are + received by the toplevel window, and then sent down the focus + focus chain. Toolkits will usually check for shortcuts or + accelerators before sending the event to the focus widget. If + such a shortcut is defined, the respective action is taken + rather than passing the event through to the focus + widget. This means, accelerators in the outmost window always + work properly, whereas accelerators defined inside an embedded + client only work if that client actually has focus. XEmbed + solves this problem with two messages, + XEMBED_REGISTER_ACCELERATOR and XEMBED_UNREGISTER_ACCELERATOR. + With XEMBED_REGISTER_ACCELERATOR, a client can reserve a + certain key/modifier combination as shortcut or + accelerator. The message is passed through to the topmost + embedder, where the key combination is stored. An + XEMBED_UNREGISTER_ACCELERATOR message releases the key again. + + + + Modality + + If an application window is shadowed by a modal dialog, no user + input is supposed to get through. The XEmbed design ensures this + for keyboard input, because the toplevel window knows about its + modal state and will not pass key events through. Embedded clients + thus inherit the modality from the topmost embedder. Mouse input, + however, is sent directly to the embedded clients by the X-Server, + unaffected by the modality of the application window. To give + clients the possibility to behave correctly when being shadowed by + a modal dialog, an embedder can choose to send an + XEMBED_MODALITY_ON message to its client when it becomes shadowed, + and an XEMBED_MODALITY_OFF message when it leaves modality + again. If the client contains embedders itself, those have to pass + both messages through to their clients. + + + + Drag and drop (XDND) + + XDND drag-and-drop does not work with reparented external + windows, since messages are exchanged with the toplevel window + only. This is done for performance reasons. While it is cheap to + get the window under the mouse pointer, it is very expensive to + get a window under another window. Unfortunately, this is required + quite often when dragging objects around, since the pointer + may overlap the drag icon. + + + Solving the drag-and-drop problem, however, is quite easy, + since the XDND protocol was carefully designed in a way that + makes it possible to support embedded windows. Basically, the + embedder has to operate as drag-and-drop proxy for the client. Any + XDND messages like XdndEnter, Xdnd,Leave, etc. simply have to be + passed through. A toollkit's XDND implementation has to take this + situation in consideration. + + + + + Embedding life cycle + + The protocol is started by the embedder. The window ID of + the client window is passed (by unspecified means) to the + embedding application, and the embedder calls + XReparentWindow() to reparent the client + window into the embedder window. + + + Implementations may choose to support an alternate method of + beginning the protocol where the window ID of the embedder + is passed to client application and the client creates a window + within the embedder, or reparents an existing window into + the embedder's window. Which method of starting XEmbed is + used a matter up to higher level agreement and outside the + scope of this specification. + + + In either case the client window must have a property called + _XEMBED_INFO on it. This property has type _XEMBED_INFO + and format 32. The contents of the property are: + + + _XEMBED_INFO + + + + FieldTypeComments + + + + + versionCARD32The protocol version + + + flagsCARD32A bitfield of flags + + + +
+ + The version field indicates the + maximum version of the protocol that the client supports. + The embedder should retrieve this field and set the data2 field + of the XEMBED_EMBEDDED_NOTIFY to + Min (version, max version supported by embedder). + The version number corresponding to the current version of the + protocol is 0. + [Should the version be defined as (Major << 16 | Minor) ?] + + + The currently defined bit in the + flags field is: + + /* Flags for _XEMBED_INFO */ +#define XEMBED_MAPPED (1 << 0) + + + XEMBED_MAPPED + + + If set the client should be mapped. The embedder must + track the flags field by selecting for PropertyNotify + events on the client and map and unmap the client + appropriately. (The embedder can leave the client unmapped + when this bit is set, but should immediately unmap the + client upon detecting that the bit has been unset.) + + + Rationale: the reason for using this bit rather than + MapRequest events is so that the client can reliably + control it's map state before the inception of the + protocol without worry that the client window will + become visible as a child of the root window. + + + + + + To support future expansion, all fields not currently defined + must be set to zero. To add proprietary extensions to the + XEMBED protocol, an application must use a separate property, rather + than using unused bits in the struct field or extending the + _XEMBED_INFO property. + + + At the start of the protocol, the embedder first sends an + XEMBED_EMBEDDED_NOTIFY message, then sends + XEMBED_FOCUS_IN, XEMBED_WINDOW_ACTIVATE, and XEMBED_MODALITY_ON + messages as necessary to synchronize the state of the + client with that of the embedder. Before any of these messages + received, the state of the client is: + + Not focused + Not active + Modality off + + + + If the embedder is geometry managed and can change its size, it + should obey the client's WMNormalHints settings. Note that + most toolkits will not have equivalents for all the hints in + the WMNormalHints settings, clients must not assume that the + requested hints will be obeyed exactly. The + width_inc, + height_inc, + min_aspect, and + max_aspect fields are examples of + fields from WMNormalHints that are unlikely to be supported + by embedders. + + + The protocol ends in one of three ways: + + + + + The embedder can unmap the client and reparent the client + window to the root window. If the client receives an + ReparentNotify event, it should check the + parent field of the + XReparentEvent structure. If this + is the root window of the window's screen, then the protocol + is finished and there is no further interaction. If it + is a window other than the root window, then the protocol + continues with the new parent acting as the embedder window. + + + + + The client can reparent its window out of the embedder + window. If the embedder receives a ReparentNotify signal + with the window field being the + current client and the parent + field being a different window, this indicates the end + of the protocol. + + + [ GTK+ doesn't currently handle this; but it seems useful + to allow the protocol to be ended in a non-destructive + fashion from either end. ] + + + + + The client can destroy its window. + + + + + + Message Specifications + + An XEmbed message is an X11 client message with message type + "_XEMBED". The format is 32, the first three data longs carry the + toolkit's X time (l[0]), the message's major opcode (l[1]) and the + message's detail code (l[2]). If no detail is required, the value + passed has to be 0. The remaining two data longs (l[3] and l[4]) + are reserved for data1 and data2. Unused bytes of the client + message are set to 0.

+ + + XEMBED_WINDOW_ACTIVATE / XEMBED_WINDOW_DEACTIVATE + + Sent from the embedder to the client when the window becomes + active or inactive, i.e. when the window gets or looses the + keyboard input focus. If the client contains embedders itself, + those have to pass the message through to their clients. + + + Note that no XEMBED_FOCUS_IN or XEMBED_FOCUS_OUT messages + should be sent when the toplevel window gains or loses + focus. The XEMBED_FOCUS_IN and XEMBED_FOCUS_OUT messages + refer only to focus within the + toplevel window and are independent of toplevel activation + state. This independence is necessary so that input focus + within a toplevel can be moved programmatically when the + toplevel doesn't have input focus. + + + [ GTK+ is currently in violation of the preceding note, + and sends FOCUS_IN and FOCUS_OUT only when the toplevel + is active. See + GNOME bug #67943 ] + + + Widgets within the client should typically be displayed with + the focus only when the client both has focus and is active. + + + + XEMBED_REQUEST_FOCUS + + Sent from the client to the embedder when the client wants + focus.

+ + The accelerator_id is used to identify the accelerator when + activating the accelerator. The reason for using an + accelerator ID instead of identifying accelerators simply by + key symbol and modifiers is to allow the correct handling of + overloaded accelerators with embedded widgets. (An accelerator + is overloaded if there multiple accelerators on the same key, + usually because of accidental collisions.) When an overloaded + accelerator is pressed repeatedly, the toplevel activates + accelerators on that key in round-robin fashion. If this + round-robin behavior is not supported by the embedding + toolkit, picking an arbitrary accelerator for the key and + activating it is acceptable. Well designed applications should + avoid collisions in any case. + + + + Ordering the round-robin of conflicting accelerators + in a predictable (geometric or in focus chain) order + is desirable. This can be achieved if the toplevel sorts + the conflicting accelerators as if they applied to the + client instead of widgets within the client and then + each client does the same sort on the subset of conflicting + accelerators within it. To get this to work properly + if there are conflicting accelerators within a client, say widget + A and B both have the same mnemonic, then instead of + registering one accelerator for widget A and one for + widget B, the client should register two accelerators that + corresponds to both A and B, and then when + XEMBED_ACTIVATE_ACCELERATOR is received for either + accelerator, implement round robin between A and B + with the correct sorting. + + + + The modified bit field is a bitwise OR of values indicating + various accelerators; these indicate logical accelerator + keys rather than corresponding directly to the bits in + the XKeyEvent state field. + + /* Modifiers field for XEMBED_REGISTER_ACCELERATOR */ +#define XEMBED_MODIFIER_SHIFT (1 << 0) +#define XEMBED_MODIFIER_CONTROL (1 << 1) +#define XEMBED_MODIFIER_ALT (1 << 2) +#define XEMBED_MODIFIER_SUPER (1 << 3) +#define XEMBED_MODIFIER_HYPER (1 << 4) + + (Meta is intentionally left out here because if you try to separate + Alt and Meta, a large fraction of users will experience problems + with their keyboard setups... there is no reliably standard + of which one is the primary modifier key and on the Alt key.) + + + On activation, the topmost embedder will send + XEMBED_ACTIVATE_ACCELERATOR to its client; if the + accelerator was registered by an embedder inside that + client, the embedder will send XEMBED_ACTIVATE_ACCELERATOR + to its client and so forth. + + + Note that the assignment of ID's is private for each pair + of client and embedder and when accelerators are being + propagated through multiple client/embedder pairs, a + different accelerator ID may be used for each pair. + + + The XEMBED_UNREGISTER_ACCELERATOR message releases the key + combination again. + + + XEMBED_UNREGISTER_ACCELERATOR + + + + detailinteger ID passed + to XEMBED_REGISTER_ACCELERATOR + + + +

If the + client contains embedders itself, those have to pass the message + through to their clients. An embedded control should ignore + mouse input while modality is active.

For this reason X errors + must be trapped when performing any operation with a window + not created by the application. This is done by using + XSetErrorHandler(). + A sample implementation of trapping errors in C looks like: + + #include <X11/Xlib.h> + +static int trapped_error_code = 0; +static int (*old_error_handler) (Display *, XErrorEvent *); + +static int +error_handler(Display *display, + XErrorEvent *error) +{ + trapped_error_code = error->error_code; + return 0; +} + +void +trap_errors(void) +{ + trapped_error_code = 0; + old_error_handler = XSetErrorHandler(error_handler); +} + +int +untrap_errors(void) +{ + XSetErrorHandler(old_error_handler); + return trapped_error_code; +} + + + Forwarding X Events + + An XEmbed embedder has to forward key-press and key-release + events to its respective client. + + + Key events are forwarded by changing the event's window field + to the window handle of the client and sending the modifed + message via XSendEvent() to the embedder, + with no event mask and propagation turned off. + + + Note: XEmbed requires toolkits to handle key-events that come + from a SendEvent request. That means, if somebody can access + your X-Server, it's possible to fake keyboard input. Given + that most toolkits accept sent key events today anyway and the + X Server is typically protected through magic cookie + authorization, this is not considered to be an + issue. Applications with higher security requirements may + choose not to use embedded components, though, and to filter + out any events coming from XSendEvent(). + + + Given that Window client is the client's window handle, + here is a piece of code of an imaginary event-loop in C that does + the forwarding. + + #include <X11/Xlib.h> + +void handle_event( + Display* dpy, /* display */ + XEvent* ev /* event */ +){ + if ( ev->type == KeyPress || ev->type == KeyRelease ) { + ev->xkey.window = client; + trap_errors(); + XSendEvent( dpy, client, False, NoEventMask, ev ); + XSync( dpy, False ); + if (untrap_errors()) { + /* Handle failure */ + } + + return; + } + ... /* normal event handling */ +} + + + Sending XEmbed messages + + Given that Time x_time contains the timestamp from the event + currently being processed. (CurrentTime is generally the best + choice if no event is being processed), here is a valid + implementation in C of sending an XEMBED message: + + #include <X11/Xlib.h> + +void send_xembed_message( + Display* dpy, /* display */ + Window w, /* receiver */ + long message, /* message opcode */ + long detail /* message detail */ + long data1 /* message data 1 */ + long data2 /* message data 2 */ +){ + XEvent ev; + memset(&ev, 0, sizeof(ev)); + ev.xclient.type = ClientMessage; + ev.xclient.window = w; + ev.xclient.message_type = XInternAtom( dpy, "_XEMBED", False ); + ev.xclient.format = 32; + ev.xclient.data.l[0] = x_time; + ev.xclient.data.l[1] = message; + ev.xclient.data.l[2] = detail; + ev.xclient.data.l[3] = data1; + ev.xclient.data.l[4] = data2; + trap_errors(); + XSendEvent(dpy, w, False, NoEventMask, &ev); + XSync(dpy, False); + if (untrap_errors()) { + /* Handle failure */ + } +} + + + + Issues + + Implementation of modality + + The protocol could be simplified by removing the + XEMBED_MODALITY_ON and XEMBED_MODALITY_OFF messages in favor + of requiring the embedder to map an input-only window over + it's child when it beings shadowed by a modal grab. + + + One possible reason for the current protocol is that a toolkit + might want to have elements such as scrollbars that remain + active even when grab shadowed. (I know of no toolkit that + actually implements this.) + + + + Clarify function of timestamps + + The function of the timestamp arguments needs to be clarified, + as well as the requirements for what should be passed + in the field. The original draft of the specification + contained the text about the determining the timestamp. + +
+ + The x time is to be updated whenever the toolkit receives an + event from the server that carries a timestamp. XEmbed client + messages qualify for that. + + + Hint to implementators: Check that the xembed time stamp + is actually later than your current x time. While this cannot + happen with ordinary XEvents, delayed client messages may have + this effect. Be prepared that evil implementations may even + pass CurrentTime sometimes. + +
+ + But I [OWT] wouldn't agree with this advice. The point + of a timestamp is to make sure that when events are processed + out of order, the event generated last by the user wins + for shared resources such as input focus, selections, and + grabs. An example of where this can matter is if you have + + Toplevel Window + Embedder + Client + Text Entry 1 + Embedder + Client + Text Entry 2 + + If the entries are set to select the text on focus in, and the + user hits TAB in quick succession, then the timestamps on the + FOCUS_IN events are what makes sure that Entry 2 actually ends + up owning the PRIMARY selection, instead of it being a race + between the two clients. But in situations like this having + the correct timestamp only matters if a user action triggers + the behavior. + + + Hence the advice that the timestamp should be the time from + the event currently being processed. + + + If no explicit user action is involved, then the + best thing to do is to use CurrentTime; using the timestamp + from the last X event received can cause problems if the + ultimate trigger of the behavior is a timeout or network + and the last X event happened some time in the distant past. + + + + Complexity of accelerator handling + + The current specification for accelerator handling is a little + complex. Most of the complexity (the accelerator IDs) comes + from the need to handle conflicting accelerators. + GTK+ currently implements a simpler scheme where grabs are + identified only by key symbol and modifier and conflicting + mnemonic resolution doesn't work across embedder/client + interfaces. + + + + Infinite loops in focusing + + There is the potential for infinite loops of focusing - + Consider the case: + + Toplevel Window + Embedder + Client + + Where there are no focusable sites in the client or in the + toplevel window. Then if Tab is pressed, the embedder + will send: FOCUS_IN/FOCUS_FIRST to the client, the client will + send FOCUS_NEXT to the embedder, the toplevel window will + wrap the focus around and send FOCUS_IN/FOCUS_FIRST to the + client... + + + The minimum mechanism that seems necessary to prevent this + loop is a serial number in the FOCUS_IN/FOCUS_FIRST message + that is repeated in a resulting FOCUS_NEXT message. + + + A possibly better way of handling this could be to make FOCUS_IN have + an explicit response; that, is, add a XEMBED_FOCUS_IN_RESPONSE + that the client must send to the embedder after receipt + of a FOCUS_IN message. + + + + XEMBED_FOCUS_IN_RESPONSE + + + + detail1 if the client accepted the focus, 0 otherwise + + + data1serial number from XEMBED_FOCUS_IN + + + +
+ + The main problem with requiring a response here is that caller + needs to wait for the return event, and to handle cases like + parent (client 1) => child (client 2) => grandchild (client 1), + it probably needs to process all sorts of incoming events at + this point. If the user hits TabTab + in quick succession things could get very complicated. + + + + Robustness + + The protocol, as currently constituted, is not robust against + the embedder crashing. This will result in the embedder + window being destroyed by the X server, and, as a consequence + client's window being unexpectedly destroyed, which will likely cause the + client to die with a BadWindow error. + + + To fix this requires an X protocol extension which extends + the functionality of XChangeSaveSet() in + two areas: + + + + + Allow it to be specified that the saved window should be + reparented to the root window rather than to the nearest + parent. (The nearest parent typically being the window + manager's frame window, reparenting to the nearest + parent only saves the client until the window manager + cleans up and destroys the frame window.) + + + + + Allow it to be specified that the saved window should be + unmapped rather than then mapped. (Without this capability + the client will mapped as a child of the root window, + which will be confusing to the user.) + + + + + + Sensitivity + + Toolkits such as Qt and GTK+ have a concept of disabled + widgets. This notion is typically hierarchical, so if + the embedder or a ancestory of the embedder becomes + insensitive, widgets inside the client should be displayed as, + and act insensitive as well. + + + + Directional focusing + + Some toolkits, such as GTK+, support, along with the standard + concept of a focus chain, the idea of directional + focusing; it's possible in some cases to navigate + focus using the arrow keys. To do this perfectly, you need + to have information about the coordinates of the original + focus window, which is hard to do in an embedding context, + but a good approximation is to, when focusing into a + container, provide the side of the container where focus + is coming from and to focus the "middle widget" on this side. + + + This could be supported by adding an extra data field to + to the XEMBED_FOCUS_FIRST/XEMBED_FOCUS_LAST subtypes + of XEMBED_FOCUS_IN and to XEMBED_FOCUS_NEXT and + XEMBED_FOCUS_PREV, which would contain: + + /* Directions for focusing */ +#define XEMBED_DIRECTION_DEFAULT 0 +#define XEMBED_DIRECTION_UP_DOWN 1 +#define XEMBED_DIRECTION_LEFT_RIGHT 2 + + Applications supporting only normal tab focusing would always + pass XEMBED_DIRECTION_DEFAULT and treat all received + directions as XEMBED_DIRECTION_DEFAULT. + + + The argument against supporting this is that it's a rather + confusing feature to start with (many widgets eat arrow keys + for other purposes), and becomes more confusing if you have + a application containing widgets from different toolkits, + some of which support it, some of which don't. + + + + Modal dialogs + + The specification doesn't have any provisions for handling the + case where an embedded client wants to put up a dialog. Such a + dialog should be transient-for the real toplevel window, and, + if modal, should block the entire toplevel window. To fully + implement this, you would need some concept of an application + that spanned multiple toplevel windows in multiple clients. + + + + Propagation of key presses + + It's frequently useful to have keybindings that trigger on + a widget if the focus is on a child of that widget. For + instance, ControlPageUp + and ControlPageUp switch + pages in a notebook widget when the focus is on a child + of the notebook. The XEmbed spec currently has no handling + of this situation. + + + The simplest solution would be to specify that if the client + widget doesn't handle a key press sent to it, it then sends + the event back to the embedder. Some care would be required + in the embedder handle infinite loops, but it shouldn't + be that bad. + + + + Handling of toplevel modes + + GTK+-2.0 contains a feature for key navigation of tooltips + where Control-F1 toggles a "tooltips keyboard mode" where + the tooltip for the currently focused window is displayed. + There is no way of propagating this across XEMBED. + This feature could clearly be implemented the same + way as XEMBED_WINDOW_ACTIVATE, but adding a pair of + messages for every feature of this type seems excessive. + + + A possible alternate idea would be to add a _XEMBED_STATE + property that the embedder sets on the client window which + is a list of atoms. This could actually be used to + replace XEMBED_WINDOW_ACTIVATE, and XEMBED_MODALITY_ON, + simplifying the protocol. + + + There are some race conditions in maintaining this property + if the client is allowed to reparent itself out of the + embedder that would have to be considered. + + + + + Change history + + "Version 1.0 DRAFT 1", 22 April 2000, Matthias Ettrich + + + + + "Version 1.0 DRAFT 2", 15 August 2000, Matthias Ettrich + + + + + Version 0.5, 19 April 2002, Owen Taylor + + + + + Add the life-cycle chapter, including _XEMBED_INFO + property, and the XEMBED_MAPPED flags. + + + + + Define the data2 for XEMBED_EMBEDDED_NOTIFY to be the + protocol version in use. + + + + + Replaced XEMBED_GRAB_KEY scheme for handling accelerators + with XEMBED_REGISTER_ACCELERATOR. + + + + + Removed text "This also means that the client has to + prepare for becoming visible anytime without filing a map + request itself" from the description of + XEMBED_EMBEDDED_NOTIFY". + + + + + Added text about the independence of FOCUS_IN/OUT and + ACTIVATE/DEACTIVE to the description of + XEMBED_WINDOW_ACTIVATE / XEMBED_WINDOW_DEACTIVATE. + + + + + Added note about fields in WMNormalHints not necessarily + being obeyed by embedders. + + + + + Removed mention of XEMBED_PROCESS_NEXT_EVENT, which is + no longer part of the protocol. + + + + + Added definitions of "Active" and "Focused" to the + definitions section. + + + + + Added issues and change history sections. + + + + + Lots of textual editing for clarity, style consistency. + + + + + Converted to docbook format. + + + + + + +

- - - - - - - Overview - - XEmbed is a protocol that uses basic X mechanisms such as client - messages and reparenting windows to provide embedding of a - control from one application into another application. Some - of the goals of the XEmbed design are: - - - - - Support for out-of process controls, written in any toolkit - or even plain Xlib. - - - - - Support for in-process-controls when mixing different - toolkits in one process. - - - - - Smooth integration of the embedding application and embedded client - in areas such as input device handling and visual feedback. - - - - - Easy implementation. A full implementation supporting all - details correctly may require minor toolkit modifications, - but it should be possible to get basic functionality going - in less than 1000 lines of code. - - - - - Goal 1 is the most urgent one. A embedding specification allows - developers to write applets for whatever desktop the user is - using in whatever toolkit they prefer. Goal 2 is more of - something to keep in mind than a immediate requirement. While - there are other ways to mix two or more toolkits, using XEmbed - might be the easiest and thus most comfortable way. Goal 3 - describes the targeted level of integration. The users should - not necessarily notice that they work with embedded controls; - devices like the keyboard and the mouse should work as expected, - inactive windows should look like they are inactive, and so - forth. The level of integration may, however, be limited by goal - 4. In order for the protocol to be successful, it's crucial to - get implementations for the most important toolkits. Thus, the - implementation should not require too much coding and no or only - few modifications to the toolkit's kernel. - - - At the time of writing, an implementation of XEmbed is included - in GTK+-2.0 that mostly conforms to this version of the - specification. The main area of divergence is in the area of - accelerators, where a simpler scheme is implemented than the - XEMBED_REGISTER_ACCELERATOR, XEMBED_UNREGISTER_ACCELERATOR - accelerator scheme described here. The KDE libraries (libkdeui) - include QXEmbed, a mostly-complete implementation for Qt of an - earlier version of the protocol. - - - - Definitions - - - Active - - - A toplevel window is active if it - currently is receiving keyboard events. (The window or a - descendent has the X keyboard focus.) A widget within the - toplevel is active if the toplevel is active, regardless - of whether that widget has the input focus within the - toplevel. - - - - - Client - - - In an embedding situation, the client is - the window that is embedded into an embedder. Sometimes also - called a plug. (Note that the usage here should not be - confused with the typical X usage of "client" to mean an application - connecting to the X server. That is always referred to as - an application in this document) - - - [ Should we replace client by some other term in - this document to avoid the confusion? ] - - - - - Embedder - - - In an embedding situation, the embedder - is the graphical location that embeds an external - client. Sometimes also called a socket or site. - - - - - Focused - - - A widget is focused if it receives - keyboard events within its toplevel. This is without - regard to whether the toplevel is active, and has nothing - to do with the X keyboard focus. - - - - - - - Rationale and discussion - - The basis for handling embedding is that the embedder acts like - a "window manager" for the client. (The window management - protocol is defined in the X Inter-Client Communications Manual - or ICCCM). The embedder selects with SubstructureRedirectMask - on its window so that it can intercept, and then the client - window is reparented (using - XReparentWindow()) - as a child of the embedder window. Because of the substructure redirect, the - embedder is able to intercept calls to move or resize the client - window, and handle them as appropriate to the location in the - embedding application. (Map requests are also redirected, but - XEmbed actually handles map requests separately... see the - description of the XEMBED_MAPPED flag.) - - - The window management protocol is sufficient to handle the - basics of visual embedding, but has deficiencies in other areas - that prevent it from providing natural integration between - toolkits. These areas include: - - - - window activation state - keyboard focus - tab focus chain - keyboard short cuts / accelerators - modality - drag and drop (XDND) - - - - The XEmbed protocol is mainly concerned with communicating - additional information between embedder and client to handle - these areas. Communication in XEmbed is done by forwarding - slightly modified XEvents using - XSendEvent(), - by sending special xembed messages, and by setting X properties. In addition, - standard ICCCM features like WMNormalHints are used where - appropriate. - - - The next sections explain why these problems occur with the - simple "window management" approach and how XEmbed solves them. - - - - Window activation state - - A widget has to know the activation state of its toplevel - window. This enables input widgets like a line editor, to display - a blinking cursor only when the user can actually type into it. In - addition, certain GUI styles choose to display inactive windows - differently, typically with a lighter and less contrasting color - palette. - - - Unfortunately, there are no such messages like WindowActivate - or WindowDeactivate in the X protocol. Instead, a window knows - that it is active when it receives keyboard focus (XFocusInEvent - with certain modes) or looses it (XFocusOutEvent with certain - modes). This applies to embedded child windows only, when the - mouse pointer points onto one of the child's subwindows in the very - moment the window manager puts the X focus on the toplevel - window. For that reason, XEmbed requires the embedders to pass - XEMBED_WINDOW_ACTIVATE and XEMBED_WINDOW_DEACTIVATE messages to - their respective clients whenever they get or loose X keyboard - - - - - Keyboard focus - - The delivery of keyboard events in X is designed in a way that - does not correspond to the typical operation of modern - toolkits; instead it seems designed to allow things to allow - things to work without either a window manager or a focus - handling in the toolkit. Typically, key events are sent to the - window which has the X input focus (set with - XSetInputFocus()). However, if the mouse pointer is inside - that focus window, the event is sent to the subwindow of the - focus window that is under the moues pointer. In modern toolkits, - the X input focus is typically left on the toplevel window and - a separate logical input focus is implemented within the - toolkit. The toolkit ignores the window that the key event is - actually sent to (which might be a scrollbar or other random - widget within the toplevel, depending on where the mouse - pointer is), and distributes key events to widget with the - logical input focus. - - - So, for standard operation, the behavior where key events are sent - to the window with the mouse pointer is simply ignored. But - with embedded windows, it causes problems, since, if the - mouse pointer is within the embedded window, the outer toolkit - doesn't see any key events, even if the logical keyboard focus - is elsewhere within the outer toolkits toplevel window. - - - Previous embedding techniques therefore required clients to - forward any key event they receive (KeyPress and KeyRelease) to - their respective embedder. In order to support multiple levels of - embedding, events that stem from a SendEvent request had to be - forwarded as well. While this is a possible solution, it adds both - race conditions and inefficency - - - The solution proposed by XEmbed is is to beat X11 with its own - weapons: The topmost toolkit is required - to keep the X input focus on one of its own windows without - any embedded children. Keeping the focus on such a window - ensures that key events are always delivered to the outer - toolkit and thus can be forwarded easily to any embedded - window. This also makes it possible to use this part of XEmbed - with clients that do not support the protocol at all, without - breaking keyboard input for the embedding application. - - - In detail, the topmost embedder creates a not-visible X Window to - hold the focus, the focus proxy. (It might be a 1x1 child - window of toplevel located at -1,-1.) Since the focus proxy isn't - an ancestor of the client window, the X focus can never move - into the client window because of the mouse pointer location. - In other words, whenever the outer window is activated - (receives the X input focus), it has to put the X focus on the - FocusProxy by calling XSetInputFocus(). - - - The trouble with this is, that you should not use XSetInputFocus() - without a proper time stamp from the Server, to avoid race - conditions. Unfortunately, the XFocusIn even does not carry a - timestamp. The solution to this is, to ask the window manager for - the WM_TAKE_FOCUS window protocol. Thus, whenever the window is - activated, it will receive a WM_PROTOCOLS client message with - data.l[0] being WM_TAKE_FOCUS and data.l[1] being a proper - timestamp. This timestamp can be used safely for the call to - XSetInputFocus(). - - - If an embedder widget gets the logical input focus, it sends - an XEMBED_FOCUS_IN message to its client. The client that - receives this messages knows that its logical focus is now - also the logical focus of the application window and will - react accordingly. If its logical focus lies on the line - editor control mentioned above, and the window is active, the - editor will show a blinking cursor after processing this - message. - - - In a similar fashion, if the embedder looses focus, it sends - an XEMBED_FOCUS_OUT message. - - - - Tab focus chain - - X does not have a concept of a tab focus chain, it is up to the - toolkit or the application to implement it. Since the concept - is standard among almost all toolkits, XEmbed supports it. An - XEmbed client integrates perfectly in the embedder's tab focus - chain, i.e. the user can tab onto the client, through all its - widgets and back to the outer world without noticing that they - traversed an external window. - - - As explained in the previous section, an embedder sends an - XEMBED_FOCUS_IN message to its client when it gets focus. The - detail code of this message is per default 0, that is, - XEMBED_FOCUS_CURRENT. It indicates that the clients keeps its own - logical focus where it was. To support tabbing, XEmbed provides - two more detail codes, namely XEMBED_FOCUS_FIRST and - XEMBED_FOCUS_LAST, that indicate that the client should move - its focus to the beginning or end of the focus chain. - - - When the user tabs to the very end of a client's tab chain, the - client follows the request (i.e. it puts its logical focus back to - the beginning its tab chain) and sends an XEMBED_FOCUS_NEXT - message to the embedder. If the embedder has siblings that accept - tab focus, it will do a virtual tab forward. As a result, it will - loose focus itself and consequently send an XEMBED_FOCUS_OUT - message to the client. As expected, the client's line edit control - from the previous example will stop blinking. - - - Backward tabbing is done exactly in the same manner, using the - XEMBED_FOCUS_PREV message. - - - - Keyboard short cuts / accelerators - - XEmbed is designed in such a way, that keyboard events are - received by the toplevel window, and then sent down the focus - focus chain. Toolkits will usually check for shortcuts or - accelerators before sending the event to the focus widget. If - such a shortcut is defined, the respective action is taken - rather than passing the event through to the focus - widget. This means, accelerators in the outmost window always - work properly, whereas accelerators defined inside an embedded - client only work if that client actually has focus. XEmbed - solves this problem with two messages, - XEMBED_REGISTER_ACCELERATOR and XEMBED_UNREGISTER_ACCELERATOR. - With XEMBED_REGISTER_ACCELERATOR, a client can reserve a - certain key/modifier combination as shortcut or - accelerator. The message is passed through to the topmost - embedder, where the key combination is stored. An - XEMBED_UNREGISTER_ACCELERATOR message releases the key again. - - - - Modality - - If an application window is shadowed by a modal dialog, no user - input is supposed to get through. The XEmbed design ensures this - for keyboard input, because the toplevel window knows about its - modal state and will not pass key events through. Embedded clients - thus inherit the modality from the topmost embedder. Mouse input, - however, is sent directly to the embedded clients by the X-Server, - unaffected by the modality of the application window. To give - clients the possibility to behave correctly when being shadowed by - a modal dialog, an embedder can choose to send an - XEMBED_MODALITY_ON message to its client when it becomes shadowed, - and an XEMBED_MODALITY_OFF message when it leaves modality - again. If the client contains embedders itself, those have to pass - both messages through to their clients. - - - - Drag and drop (XDND) - - XDND drag-and-drop does not work with reparented external - windows, since messages are exchanged with the toplevel window - only. This is done for performance reasons. While it is cheap to - get the window under the mouse pointer, it is very expensive to - get a window under another window. Unfortunately, this is required - quite often when dragging objects around, since the pointer - may overlap the drag icon. - - - Solving the drag-and-drop problem, however, is quite easy, - since the XDND protocol was carefully designed in a way that - makes it possible to support embedded windows. Basically, the - embedder has to operate as drag-and-drop proxy for the client. Any - XDND messages like XdndEnter, Xdnd,Leave, etc. simply have to be - passed through. A toollkit's XDND implementation has to take this - situation in consideration. - - - - - Embedding life cycle - - The protocol is started by the embedder. The window ID of - the client window is passed (by unspecified means) to the - embedding application, and the embedder calls - XReparentWindow() to reparent the client - window into the embedder window. - - - Implementations may choose to support an alternate method of - beginning the protocol where the window ID of the embedder - is passed to client application and the client creates a window - within the embedder, or reparents an existing window into - the embedder's window. Which method of starting XEmbed is - used a matter up to higher level agreement and outside the - scope of this specification. - - - In either case the client window must have a property called - _XEMBED_INFO on it. This property has type _XEMBED_INFO - and format 32. The contents of the property are: - - - _XEMBED_INFO - - - - FieldTypeComments - - - - - versionCARD32The protocol version - - - flagsCARD32A bitfield of flags - - - -
- - The version field indicates the - maximum version of the protocol that the client supports. - The embedder should retrieve this field and set the data2 field - of the XEMBED_EMBEDDED_NOTIFY to - Min (version, max version supported by embedder). - The version number corresponding to the current version of the - protocol is 0. - [Should the version be defined as (Major << 16 | Minor) ?] - - - The currently defined bit in the - flags field is: - - /* Flags for _XEMBED_INFO */ -#define XEMBED_MAPPED (1 << 0) - - - XEMBED_MAPPED - - - If set the client should be mapped. The embedder must - track the flags field by selecting for PropertyNotify - events on the client and map and unmap the client - appropriately. (The embedder can leave the client unmapped - when this bit is set, but should immediately unmap the - client upon detecting that the bit has been unset.) - - - Rationale: the reason for using this bit rather than - MapRequest events is so that the client can reliably - control it's map state before the inception of the - protocol without worry that the client window will - become visible as a child of the root window. - - - - - - To support future expansion, all fields not currently defined - must be set to zero. To add proprietary extensions to the - XEMBED protocol, an application must use a separate property, rather - than using unused bits in the struct field or extending the - _XEMBED_INFO property. - - - At the start of the protocol, the embedder first sends an - XEMBED_EMBEDDED_NOTIFY message, then sends - XEMBED_FOCUS_IN, XEMBED_WINDOW_ACTIVATE, and XEMBED_MODALITY_ON - messages as necessary to synchronize the state of the - client with that of the embedder. Before any of these messages - received, the state of the client is: - - Not focused - Not active - Modality off - - - - If the embedder is geometry managed and can change its size, it - should obey the client's WMNormalHints settings. Note that - most toolkits will not have equivalents for all the hints in - the WMNormalHints settings, clients must not assume that the - requested hints will be obeyed exactly. The - width_inc, - height_inc, - min_aspect, and - max_aspect fields are examples of - fields from WMNormalHints that are unlikely to be supported - by embedders. - - - The protocol ends in one of three ways: - - - - - The embedder can unmap the client and reparent the client - window to the root window. If the client receives an - ReparentNotify event, it should check the - parent field of the - XReparentEvent structure. If this - is the root window of the window's screen, then the protocol - is finished and there is no further interaction. If it - is a window other than the root window, then the protocol - continues with the new parent acting as the embedder window. - - - - - The client can reparent its window out of the embedder - window. If the embedder receives a ReparentNotify signal - with the window field being the - current client and the parent - field being a different window, this indicates the end - of the protocol. - - - [ GTK+ doesn't currently handle this; but it seems useful - to allow the protocol to be ended in a non-destructive - fashion from either end. ] - - - - - The client can destroy its window. - - - - - - Message Specifications - - An XEmbed message is an X11 client message with message type - "_XEMBED". The format is 32, the first three data longs carry the - toolkit's X time (l[0]), the message's major opcode (l[1]) and the - message's detail code (l[2]). If no detail is required, the value - passed has to be 0. The remaining two data longs (l[3] and l[4]) - are reserved for data1 and data2. Unused bytes of the client - message are set to 0. The event is sent to the target window with - no event mask and propagation turned off. - - - The valid XEmbed messages are: - - /* XEMBED messages */ -#define XEMBED_EMBEDDED_NOTIFY 0 -#define XEMBED_WINDOW_ACTIVATE 1 -#define XEMBED_WINDOW_DEACTIVATE 2 -#define XEMBED_REQUEST_FOCUS 3 -#define XEMBED_FOCUS_IN 4 -#define XEMBED_FOCUS_OUT 5 -#define XEMBED_FOCUS_NEXT 6 -#define XEMBED_FOCUS_PREV 7 -/* 8-9 were used for XEMBED_GRAB_KEY/XEMBED_UNGRAB_KEY */ -#define XEMBED_MODALITY_ON 10 -#define XEMBED_MODALITY_OFF 11 -#define XEMBED_REGISTER_ACCELERATOR 12 -#define XEMBED_UNREGISTER_ACCELERATOR 13 -#define XEMBED_ACTIVATE_ACCELERATOR 14 - - A detail code is required for XEMBED_FOCUS_IN. The following values - are valid: - - /* Details for XEMBED_FOCUS_IN: */ -#define XEMBED_FOCUS_CURRENT 0 -#define XEMBED_FOCUS_FIRST 1 -#define XEMBED_FOCUS_LAST 2 - - XEMBED_EMBEDDED_NOTIFY - - Sent from the embedder to the client on embedding, after - reparenting and mapping the client's X window. A client that - receives this messages knows that its window was embedded by an - XEmbed site and not simply reparented by a window manager. To support toolkits - that do not keep track of reparenting events, the message carries - the embedder's window handle as data1: - - - XEMBED_EMBEDDED_NOTIFY - - - - data1The embedder's window handle. - - - data2The protocol version in use - (see the description of _XEMBED_INFO). - - - -
- - - XEMBED_WINDOW_ACTIVATE / XEMBED_WINDOW_DEACTIVATE - - Sent from the embedder to the client when the window becomes - active or inactive, i.e. when the window gets or looses the - keyboard input focus. If the client contains embedders itself, - those have to pass the message through to their clients. - - - Note that no XEMBED_FOCUS_IN or XEMBED_FOCUS_OUT messages - should be sent when the toplevel window gains or loses - focus. The XEMBED_FOCUS_IN and XEMBED_FOCUS_OUT messages - refer only to focus within the - toplevel window and are independent of toplevel activation - state. This independence is necessary so that input focus - within a toplevel can be moved programmatically when the - toplevel doesn't have input focus. - - - [ GTK+ is currently in violation of the preceding note, - and sends FOCUS_IN and FOCUS_OUT only when the toplevel - is active. See - GNOME bug #67943 ] - - - Widgets within the client should typically be displayed with - the focus only when the client both has focus and is active. - - - - XEMBED_REQUEST_FOCUS - - Sent from the client to the embedder when the client wants - focus. The most common ocassion is when the user clicks into one - of the client's child widgets, for example a line editor, in order - to type something in. - - - The message is passed along to the topmost embedder that - eventually responds with a XEMBED_FOCUS_IN message. The focus in - message is passed all the way back until it reaches the original - focus requestor. In the end, not only the original client has - focus, but also all its ancestor embedders. - - - - XEMBED_FOCUS_IN - - Sent from the embedder to the client when it gets focus. The - detail code determines, where the client shall move its own - logical focus to. Three possibilities exist: - - - - XEMBED_FOCUS_CURRENT - - - Normal activation, does not move the clients logical - focus. - - - - - XEMBED_FOCUS_FIRST - - - Used when the user tabs onto a client. It indicates that - the client should put its logical focus onto the widget - that comes first in its own tab focus chain. - - - - - XEMBED_FOCUS_LIST - - - Used when the user tabs onto a client. It indicates that - the client should put its logical focus onto the widget - that comes first in its own tab focus chain. - - - - - - - XEMBED_FOCUS_OUT - - Sent from the embedder to the client when it looses focus. - - - - XEMBED_FOCUS_NEXT - - Sent from the client to the embedder when it reaches the end of - its logical tab chain after the user tabbed forwards. If the - embedder has siblings that accept tab focus, it will do a virtual - tab forward. As a result, it will loose focus itself and - consequently send an XEMBED_FOCUS_OUT message to the client - - - - XEMBED_FOCUS_PREV - - Sent from the client to the embedder when it reaches the - beginning of its logical tab chain after the user tabbed - backwards. If the embedder has siblings that accept tab focus, it - will do a virtual tab backward. As a result, it will loose focus - itself and consequently send an XEMBED_FOCUS_OUT message to the - client - - - - XEMBED_REGISTER_ACCELERATOR / XEMBED_UNREGISTER_ACCELERATOR - - A client that needs to reserve a certain key/modifier - combination as shortcut or accelerators, sends a XEMBED_REGISTER_ACCELERATOR - message to its embedder. As long as the embedder itself is a child - of a client, the accelerator will be propagated up to the toplevel. - - - XEMBED_REGISTER_ACCELERATOR - - - - detailaccelerator_id - - - data1X key symbol - - - data2bit field of modifier values - - - -
- - The accelerator_id is used to identify the accelerator when - activating the accelerator. The reason for using an - accelerator ID instead of identifying accelerators simply by - key symbol and modifiers is to allow the correct handling of - overloaded accelerators with embedded widgets. (An accelerator - is overloaded if there multiple accelerators on the same key, - usually because of accidental collisions.) When an overloaded - accelerator is pressed repeatedly, the toplevel activates - accelerators on that key in round-robin fashion. If this - round-robin behavior is not supported by the embedding - toolkit, picking an arbitrary accelerator for the key and - activating it is acceptable. Well designed applications should - avoid collisions in any case. - - - - Ordering the round-robin of conflicting accelerators - in a predictable (geometric or in focus chain) order - is desirable. This can be achieved if the toplevel sorts - the conflicting accelerators as if they applied to the - client instead of widgets within the client and then - each client does the same sort on the subset of conflicting - accelerators within it. To get this to work properly - if there are conflicting accelerators within a client, say widget - A and B both have the same mnemonic, then instead of - registering one accelerator for widget A and one for - widget B, the client should register two accelerators that - corresponds to both A and B, and then when - XEMBED_ACTIVATE_ACCELERATOR is received for either - accelerator, implement round robin between A and B - with the correct sorting. - - - - The modified bit field is a bitwise OR of values indicating - various accelerators; these indicate logical accelerator - keys rather than corresponding directly to the bits in - the XKeyEvent state field. - - /* Modifiers field for XEMBED_REGISTER_ACCELERATOR */ -#define XEMBED_MODIFIER_SHIFT (1 << 0) -#define XEMBED_MODIFIER_CONTROL (1 << 1) -#define XEMBED_MODIFIER_ALT (1 << 2) -#define XEMBED_MODIFIER_SUPER (1 << 3) -#define XEMBED_MODIFIER_HYPER (1 << 4) - - (Meta is intentionally left out here because if you try to separate - Alt and Meta, a large fraction of users will experience problems - with their keyboard setups... there is no reliably standard - of which one is the primary modifier key and on the Alt key.) - - - On activation, the topmost embedder will send - XEMBED_ACTIVATE_ACCELERATOR to its client; if the - accelerator was registered by an embedder inside that - client, the embedder will send XEMBED_ACTIVATE_ACCELERATOR - to its client and so forth. - - - Note that the assignment of ID's is private for each pair - of client and embedder and when accelerators are being - propagated through multiple client/embedder pairs, a - different accelerator ID may be used for each pair. - - - The XEMBED_UNREGISTER_ACCELERATOR message releases the key - combination again. - - - XEMBED_UNREGISTER_ACCELERATOR - - - - detailinteger ID passed - to XEMBED_REGISTER_ACCELERATOR - - - -
- - Hint to implementators: It is the responsibility of the - embedder to keep track of all forwarded accelerators - and to remove them when the client window dies. - - - - XEMBED_ACTIVATE_ACCELERATOR - - The XEMBED_ACTIVATE_ACCELERATOR message is sent when a - accelerator previously registered with - XEMBED_REGISTER_ACCELERATOR is activated on the toplevel - containing the embedder. - - - XEMBED_ACTIVATE_ACCELERATOR - - - - detailinteger ID passed - when registering the accelerator - - - data1flags. - - - -
- - The following bit is defined for the flags field; all - other bits must be zero. - - /* Flags for XEMBED_ACTIVATE_ACCELERATOR */ -#define XEMBED_ACCELERATOR_OVERLOADED (1 << 0) - - - - XEMBED_ACCELERATOR_OVERLOADED - - - This flag indicates that multiple accelerators exist for - the key combination within the toplevel. The toolkit - may modify the behavior of the accelerator based on - this value. For instance, if the accelerator is a - mnemonic for a button, it might activate the the button - immediately if the accelerator is not overloaded, but - when overloaded, it would only focus the button. - - - - - - - XEMBED_MODALITY_ON / XEMBED_MODALITY_OFF - - Sent from the embedder to the client when the window becomes - shadowed by a modal dialog, or when it is released again. If the - client contains embedders itself, those have to pass the message - through to their clients. An embedded control should ignore - mouse input while modality is active. Note that that keyboard - input is blocked anyway by XEmbed, since the topmost embedder will - not pass keyboard events through in modal state. - - - - - - Techniques - - - Handling errors - - Implementors of the XEmbed protocol should handle the other - party disappearing at any point. For this reason X errors - must be trapped when performing any operation with a window - not created by the application. This is done by using - XSetErrorHandler(). - A sample implementation of trapping errors in C looks like: - - #include <X11/Xlib.h> - -static int trapped_error_code = 0; -static int (*old_error_handler) (Display *, XErrorEvent *); - -static int -error_handler(Display *display, - XErrorEvent *error) -{ - trapped_error_code = error->error_code; - return 0; -} - -void -trap_errors(void) -{ - trapped_error_code = 0; - old_error_handler = XSetErrorHandler(error_handler); -} - -int -untrap_errors(void) -{ - XSetErrorHandler(old_error_handler); - return trapped_error_code; -} - - - Forwarding X Events - - An XEmbed embedder has to forward key-press and key-release - events to its respective client. - - - Key events are forwarded by changing the event's window field - to the window handle of the client and sending the modifed - message via XSendEvent() to the embedder, - with no event mask and propagation turned off. - - - Note: XEmbed requires toolkits to handle key-events that come - from a SendEvent request. That means, if somebody can access - your X-Server, it's possible to fake keyboard input. Given - that most toolkits accept sent key events today anyway and the - X Server is typically protected through magic cookie - authorization, this is not considered to be an - issue. Applications with higher security requirements may - choose not to use embedded components, though, and to filter - out any events coming from XSendEvent(). - - - Given that Window client is the client's window handle, - here is a piece of code of an imaginary event-loop in C that does - the forwarding. - - #include <X11/Xlib.h> - -void handle_event( - Display* dpy, /* display */ - XEvent* ev /* event */ -){ - if ( ev->type == KeyPress || ev->type == KeyRelease ) { - ev->xkey.window = client; - trap_errors(); - XSendEvent( dpy, client, False, NoEventMask, ev ); - XSync( dpy, False ); - if (untrap_errors()) { - /* Handle failure */ - } - - return; - } - ... /* normal event handling */ -} - - - Sending XEmbed messages - - Given that Time x_time contains the timestamp from the event - currently being processed. (CurrentTime is generally the best - choice if no event is being processed), here is a valid - implementation in C of sending an XEMBED message: - - #include <X11/Xlib.h> - -void send_xembed_message( - Display* dpy, /* display */ - Window w, /* receiver */ - long message, /* message opcode */ - long detail /* message detail */ - long data1 /* message data 1 */ - long data2 /* message data 2 */ -){ - XEvent ev; - memset(&ev, 0, sizeof(ev)); - ev.xclient.type = ClientMessage; - ev.xclient.window = w; - ev.xclient.message_type = XInternAtom( dpy, "_XEMBED", False ); - ev.xclient.format = 32; - ev.xclient.data.l[0] = x_time; - ev.xclient.data.l[1] = message; - ev.xclient.data.l[2] = detail; - ev.xclient.data.l[3] = data1; - ev.xclient.data.l[4] = data2; - trap_errors(); - XSendEvent(dpy, w, False, NoEventMask, &ev); - XSync(dpy, False); - if (untrap_errors()) { - /* Handle failure */ - } -} - - - - Issues - - Implementation of modality - - The protocol could be simplified by removing the - XEMBED_MODALITY_ON and XEMBED_MODALITY_OFF messages in favor - of requiring the embedder to map an input-only window over - it's child when it beings shadowed by a modal grab. - - - One possible reason for the current protocol is that a toolkit - might want to have elements such as scrollbars that remain - active even when grab shadowed. (I know of no toolkit that - actually implements this.) - - - - Clarify function of timestamps - - The function of the timestamp arguments needs to be clarified, - as well as the requirements for what should be passed - in the field. The original draft of the specification - contained the text about the determining the timestamp. - -
- - The x time is to be updated whenever the toolkit receives an - event from the server that carries a timestamp. XEmbed client - messages qualify for that. - - - Hint to implementators: Check that the xembed time stamp - is actually later than your current x time. While this cannot - happen with ordinary XEvents, delayed client messages may have - this effect. Be prepared that evil implementations may even - pass CurrentTime sometimes. - -
- - But I [OWT] wouldn't agree with this advice. The point - of a timestamp is to make sure that when events are processed - out of order, the event generated last by the user wins - for shared resources such as input focus, selections, and - grabs. An example of where this can matter is if you have - - Toplevel Window - Embedder - Client - Text Entry 1 - Embedder - Client - Text Entry 2 - - If the entries are set to select the text on focus in, and the - user hits TAB in quick succession, then the timestamps on the - FOCUS_IN events are what makes sure that Entry 2 actually ends - up owning the PRIMARY selection, instead of it being a race - between the two clients. But in situations like this having - the correct timestamp only matters if a user action triggers - the behavior. - - - Hence the advice that the timestamp should be the time from - the event currently being processed. - - - If no explicit user action is involved, then the - best thing to do is to use CurrentTime; using the timestamp - from the last X event received can cause problems if the - ultimate trigger of the behavior is a timeout or network - and the last X event happened some time in the distant past. - - - - Complexity of accelerator handling - - The current specification for accelerator handling is a little - complex. Most of the complexity (the accelerator IDs) comes - from the need to handle conflicting accelerators. - GTK+ currently implements a simpler scheme where grabs are - identified only by key symbol and modifier and conflicting - mnemonic resolution doesn't work across embedder/client - interfaces. - - - - Infinite loops in focusing - - There is the potential for infinite loops of focusing - - Consider the case: - - Toplevel Window - Embedder - Client - - Where there are no focusable sites in the client or in the - toplevel window. Then if Tab is pressed, the embedder - will send: FOCUS_IN/FOCUS_FIRST to the client, the client will - send FOCUS_NEXT to the embedder, the toplevel window will - wrap the focus around and send FOCUS_IN/FOCUS_FIRST to the - client... - - - The minimum mechanism that seems necessary to prevent this - loop is a serial number in the FOCUS_IN/FOCUS_FIRST message - that is repeated in a resulting FOCUS_NEXT message. - - - A possibly better way of handling this could be to make FOCUS_IN have - an explicit response; that, is, add a XEMBED_FOCUS_IN_RESPONSE - that the client must send to the embedder after receipt - of a FOCUS_IN message. - - - - XEMBED_FOCUS_IN_RESPONSE - - - - detail1 if the client accepted the focus, 0 otherwise - - - data1serial number from XEMBED_FOCUS_IN - - - -
- - The main problem with requiring a response here is that caller - needs to wait for the return event, and to handle cases like - parent (client 1) => child (client 2) => grandchild (client 1), - it probably needs to process all sorts of incoming events at - this point. If the user hits TabTab - in quick succession things could get very complicated. - - - - Robustness - - The protocol, as currently constituted, is not robust against - the embedder crashing. This will result in the embedder - window being destroyed by the X server, and, as a consequence - client's window being unexpectedly destroyed, which will likely cause the - client to die with a BadWindow error. - - - To fix this requires an X protocol extension which extends - the functionality of XChangeSaveSet() in - two areas: - - - - - Allow it to be specified that the saved window should be - reparented to the root window rather than to the nearest - parent. (The nearest parent typically being the window - manager's frame window, reparenting to the nearest - parent only saves the client until the window manager - cleans up and destroys the frame window.) - - - - - Allow it to be specified that the saved window should be - unmapped rather than then mapped. (Without this capability - the client will mapped as a child of the root window, - which will be confusing to the user.) - - - - - - Sensitivity - - Toolkits such as Qt and GTK+ have a concept of disabled - widgets. This notion is typically hierarchical, so if - the embedder or a ancestory of the embedder becomes - insensitive, widgets inside the client should be displayed as, - and act insensitive as well. - - - - Directional focusing - - Some toolkits, such as GTK+, support, along with the standard - concept of a focus chain, the idea of directional - focusing; it's possible in some cases to navigate - focus using the arrow keys. To do this perfectly, you need - to have information about the coordinates of the original - focus window, which is hard to do in an embedding context, - but a good approximation is to, when focusing into a - container, provide the side of the container where focus - is coming from and to focus the "middle widget" on this side. - - - This could be supported by adding an extra data field to - to the XEMBED_FOCUS_FIRST/XEMBED_FOCUS_LAST subtypes - of XEMBED_FOCUS_IN and to XEMBED_FOCUS_NEXT and - XEMBED_FOCUS_PREV, which would contain: - - /* Directions for focusing */ -#define XEMBED_DIRECTION_DEFAULT 0 -#define XEMBED_DIRECTION_UP_DOWN 1 -#define XEMBED_DIRECTION_LEFT_RIGHT 2 - - Applications supporting only normal tab focusing would always - pass XEMBED_DIRECTION_DEFAULT and treat all received - directions as XEMBED_DIRECTION_DEFAULT. - - - The argument against supporting this is that it's a rather - confusing feature to start with (many widgets eat arrow keys - for other purposes), and becomes more confusing if you have - a application containing widgets from different toolkits, - some of which support it, some of which don't. - - - - Modal dialogs - - The specification doesn't have any provisions for handling the - case where an embedded client wants to put up a dialog. Such a - dialog should be transient-for the real toplevel window, and, - if modal, should block the entire toplevel window. To fully - implement this, you would need some concept of an application - that spanned multiple toplevel windows in multiple clients. - - - - Propagation of key presses - - It's frequently useful to have keybindings that trigger on - a widget if the focus is on a child of that widget. For - instance, ControlPageUp - and ControlPageUp switch - pages in a notebook widget when the focus is on a child - of the notebook. The XEmbed spec currently has no handling - of this situation. - - - The simplest solution would be to specify that if the client - widget doesn't handle a key press sent to it, it then sends - the event back to the embedder. Some care would be required - in the embedder handle infinite loops, but it shouldn't - be that bad. - - - - Handling of toplevel modes - - GTK+-2.0 contains a feature for key navigation of tooltips - where Control-F1 toggles a "tooltips keyboard mode" where - the tooltip for the currently focused window is displayed. - There is no way of propagating this across XEMBED. - This feature could clearly be implemented the same - way as XEMBED_WINDOW_ACTIVATE, but adding a pair of - messages for every feature of this type seems excessive. - - - A possible alternate idea would be to add a _XEMBED_STATE - property that the embedder sets on the client window which - is a list of atoms. This could actually be used to - replace XEMBED_WINDOW_ACTIVATE, and XEMBED_MODALITY_ON, - simplifying the protocol. - - - There are some race conditions in maintaining this property - if the client is allowed to reparent itself out of the - embedder that would have to be considered. - - - - - Change history - - "Version 1.0 DRAFT 1", 22 April 2000, Matthias Ettrich - - - - - "Version 1.0 DRAFT 2", 15 August 2000, Matthias Ettrich - - - - - Version 0.5, 19 April 2002, Owen Taylor - - - - - Add the life-cycle chapter, including _XEMBED_INFO - property, and the XEMBED_MAPPED flags. - - - - - Define the data2 for XEMBED_EMBEDDED_NOTIFY to be the - protocol version in use. - - - - - Replaced XEMBED_GRAB_KEY scheme for handling accelerators - with XEMBED_REGISTER_ACCELERATOR. - - - - - Removed text "This also means that the client has to - prepare for becoming visible anytime without filing a map - request itself" from the description of - XEMBED_EMBEDDED_NOTIFY". - - - - - Added text about the independence of FOCUS_IN/OUT and - ACTIVATE/DEACTIVE to the description of - XEMBED_WINDOW_ACTIVATE / XEMBED_WINDOW_DEACTIVATE. - - - - - Added note about fields in WMNormalHints not necessarily - being obeyed by embedders. - - - - - Removed mention of XEMBED_PROCESS_NEXT_EVENT, which is - no longer part of the protocol. - - - - - Added definitions of "Active" and "Focused" to the - definitions section. - - - - - Added issues and change history sections. - - - - - Lots of textual editing for clarity, style consistency. - - - - - Converted to docbook format. - - - - - - -
