/* This is an IBus workaround. The flow of events with IBus is that every time

|
* it gets gets a key event, it:
|
||
|
|
*
|
||
|
|
* Sends it to the daemon via D-Bus asynchronously
|
||
|
|
* When it gets an reply, synthesizes a new GdkEvent and puts it into the
|
||
|
|
* GDK event queue with gdk_event_put(), including
|
||
|
|
* IBUS_FORWARD_MASK = 1 << 25 in the state to prevent a loop.
|
||
|
|
*
|
||
|
|
* (Normally, IBus uses the GTK+ key snooper mechanism to get the key
|
||
|
|
* events early, but since our key events aren't visible to GTK+ key snoopers,
|
||
|
|
* IBus will instead get the events via the standard
|
||
|
|
* GtkIMContext.filter_keypress() mechanism.)
|
||
|
|
*
|
||
|
|
* There are a number of potential problems here; probably the worst
|
||
|
|
* problem is that IBus doesn't forward the timestamp with the event
|
||
|
|
* so that every key event that gets delivered ends up with
|
||
|
|
* GDK_CURRENT_TIME. This creates some very subtle bugs; for example
|
||
|
|
* if you have IBus running and a keystroke is used to trigger
|
||
|
|
* launching an application, focus stealing prevention won't work
|
||
|
|
* right. http://code.google.com/p/ibus/issues/detail?id=1184
|
||
|
|
*
|
||
|
|
* In any case, our normal flow of key events is:
|
||
|
|
*
|
||
|
|
* GDK filter function => clutter_x11_handle_event => clutter actor
|
||
|
|
*
|
||
|
|
* So, if we see a key event that gets delivered via the GDK event handler
|
||
|
|
* function - then we know it must be one of these synthesized events, and
|
||
|
|
* we should push it back to clutter.
|
||
|
|
*
|
||
|
|
* To summarize, the full key event flow with IBus is:
|
||
|
|
*
|
||
|
|
* GDK filter function
|
||
|
|
* => Mutter
|
||
|
|
* => gnome_shell_plugin_xevent_filter()
|
||
|
|
* => clutter_x11_handle_event()
|
||
|
|
* => clutter event delivery to actor
|
||
|
|
* => gtk_im_context_filter_event()
|
||
|
|
* => sent to IBus daemon
|
||
|
|
* => response received from IBus daemon
|
||
|
|
* => gdk_event_put()
|
||
|
|
* => GDK event handler
|
||
|
|
* => <this function>
|
||
|
|
* => clutter_event_put()
|
||
|
|
* => clutter event delivery to actor
|
||
|
|
*
|
||
|
|
* Anything else we see here we just pass on to the normal GDK event handler
|
||
|
|
* gtk_main_do_event().
