Detectable auto-repeat - make a repeating key generate

Browse Source 
Sat Mar  3 16:26:33 2001  Owen Taylor  <otaylor@redhat.com>

	* gdk/x11/gdkmain-x11.c gdk/x11/gdkkeys-x11.c
	  gdk/x11/gdkevents-x11.c gdk/x11/gdkprivate-x11.c:

	Detectable auto-repeat - make a repeating key generate
	press/press/press/release instead of press/release pairs.

	If we have Xkb and XkbSetDectableAutoRepeat supports
	that, we do it that way. Otherwise, when we get
	a release event, we check ahead with XPending to see
	if the next key is a KeyPress with the same keycode
	and timestamp. (Not 100% reliable, but pretty close.)

Tue Feb 27 02:16:14 2001  Owen Taylor  <otaylor@redhat.com>

  	* gtk/gtkmain.c (gtk_propagate_event): Only do special
        special key-press grab handling for widgets within
        GtkWindows. Otherwise, fall through to normal case.

        This prevents key events being sent twice to GtkInvisible
        widgets, which can cause all sorts of mischief.
