||
* @xevent: a pointer to the XEvent to process
|
||
*
|
||
* The ::xevent signal is a low level signal that is emitted
|
||
* whenever an XEvent has been received.
|
||
*
|
||
* When handlers to this signal return %TRUE, no other handlers will be
|
||
* invoked. In particular, the default handler for this function is
|
||
* GDK's own event handling mechanism, so by returning %TRUE for an event
|
||
* that GDK expects to translate, you may break GDK and/or GTK+ in
|
||
* interesting ways. You have been warned.
|
||
*
|
||
* If you want this signal handler to queue a `GdkEvent`, you can use
|
||
* gdk_display_put_event().
|
||
*
|
||
* If you are interested in X GenericEvents, bear in mind that
|
||
* XGetEventData() has been already called on the event, and
|
||
* XFreeEventData() will be called afterwards.
|
||
*
|
||
* Returns: %TRUE to stop other handlers from being invoked for the event.
|
||
* %FALSE to propagate the event further.
