Description Sebastien Bacher 2004-10-17 19:48:45 UTC 
The problem has been reported here: http://bugs.debian.org/276734

"I've noticed that a recent update seems to have broken the
gdk_window_set_icon() function, at least as far as using the icon_window
parameter. Specifically, it doesn't seem to get around to setting the
IconWindowHint on the leader window. If i set this one hint
manually, it works as expected."

A window-maker test program is attached in the original bug report.

I've made a small test case that creates 2 windows and set the icon of the first
with a pixmap and the second with the first. The icon is not changed ...

I think this is because update_wm_hints() refuses to set hints on withdrawn windows.

	Fix #155658, Sebastian Bacher:
	
	* gdk/x11/gdkwindow-x11.h (struct _GdkToplevelX11): Add a new 
	is_leader flag.

	* gdk/x11/gdkwindow-x11.c (update_wm_hints): Set wm hints on
	leader windows even if they are withdrawn.
	(gdk_window_set_group): Mark the new leader window as such. We 
	never remove the flag again, but that should a) be vanishingly
	rare and b) not a problem, since the flag just turns off an
	optimization.

	* gdk/x11/gdkdisplay-x11.c (gdk_display_open): Mark the default
	leader window as such.
