That's simply plainly false. what happens here is that the window switch
to "Initial state is Iconic State" ICCCM WM_HINTS when you call
gtk_widget_hide() in on_window_state_event()

Look, try yourself, do xprop on your window and look for "Initial state
is Iconic State.".

It happen that metacity is currently broken and do not implents this
properly. Kwin does, xfwm4 does, but metacity does not. It used to in
previous version, but not in current version. Try in an earlier version
of metacity/gnome and you'll see by yourself.

A proof? Try "xterm -iconic" in xfwm4, in kwin and in metacity: In kwin
and xfwm4, the window starts iconic as it should. In metacity it does
not... That's exactly the same that happen with your app.

Seriuously xfwm4 does implement the standard, while metacity does not.
It happen (as already explained earlier) that your program in broken,
but it doesn't show in metacity because metacity does *not* implement
the protocol properly.

Really, I'm doing my best, but it sounds like a useless waste of time.
You do not listen not even try to understand what I'm desesperatly
tryingto tell you...

Again it's not just for xfwm4. Did you actually try with kwin, or any
descent good window manager? I guess you did not, otherwise you would
not claim such nonsense.

Because if the gtk_widget_hide() in on_window_state_event() that trigger
the start iconic flag. I already explained that.

Afgai, it's metacity that is broken, you cannot just trash all other
good window managers because metacity is broken.

Again and again and again, but you really don't seem to try to understand...

Cheers,
Olivier.
