Subject: frame-visible-p reporting t instead of 'icon
Date: Wed, 09 Nov 2011 10:41:41 +0100

Hi,

Has there been any recent changes to the code that detects when a frame
is visible or not on GTK? I didn't find anything in bzr log, but I can't
be sure.

The following snippet sometimes (erratically) reports "t" when it should
report "icon". That started happening one, maybe two weeks ago.

(defun blah (&rest args)
  (pp(frame-visible-p (selected-frame))))

(run-with-timer 2 nil 'blah)

(eval the run-with-timer, switch virtual desktops for two seconds, come
back)

I'm using frame-visible-p to handle notifications (notify me when I
don't see what's happening in emacs), so this bug is pretty annoying.

It might be a bug in my display environment, but I haven't changed
anything in a while.

(for reference, I'm using gnome-panel with metacity on ubuntu 11.10)

I get t also in 23.3, and 'icon when iconified.

What do you mean? That's what it's supposed to do. The point is I
sometimes get t when it's iconified (different virtual desktop), and
that's recent. Can you try the code snippet on trunk a bunch of times
and see if you get t when it's iconified?

Hi.

Are you running Gnome 3 or Unity by any chance?
See here: http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9893.

I'm using Gnome 3 (libgtk is 3.2.0), but with the "old" gnome desktop
environment (metacity and gnome-panel). My bug did start happening
around the time you made the fix, so your fix is probably what caused
the bug.

Can you take a look as to why that would happen? If you tell me where to
look, I'll be happy to send you the GTK messages in the buggy case.

Antoine

Hi,

Any news on this? It's still an issue for me, and I'm holding back on
updating emacs because of this bug.

Hi,

Cool, thanks!

However, at compilation, I now get:

xterm.c: In function ‘get_current_wm_state’:
xterm.c:8484:23: error: ‘struct x_display_info’ has no member named ‘Xatom_net_wm_state_hidden’
xterm.c: In function ‘x_term_init’:
xterm.c:10290:41: error: ‘struct x_display_info’ has no member named ‘Xatom_net_wm_state_hidden’

That's even after make clean.

You probably have local modifications or there was a bad merge.  Try bzr status to see what is wrong.
Also try bzr up again.

Hm, that's weird, I specifically did a bzr resolved --take-other --all
in the hope that it'd clear everything up by itself. Apparently, bzr
revert . was what I needed. Silly me. Thanks for the help!

It is hard to detect if Emacs is not on the active desktop with Unity (Compiz really).  One could try to calculate the geometries but it would probably be complicated and error prone.
It is a shame that Emacs has exposed these kind of low level details in its Lisp, it is very hard to support when the world moves on to another implementation.

Emacs did not detect iconification correctly in Unity, I fixed that at least.
