Application window not responsive when iconified

[Takkat]

How to reproduce:

Iconify an application window running from autostart with the gtk_window_iconify method from GTK2.

What is expected:

1. The application windows is minimized to its launcher icon.
2. Calling gtk_window_deiconify or gtk_window_present maximized the application.
or
3. Clicking on the launcher icon maximizes the application window.

What is observed instead:

* After startup the application window is minimized as expected.
* We can not maximize the window again with
    - gtk_window_show_all
    - gtk_window_deiconify
    - gtk_window_present
or by clicking on the Launcher icon of the running application.

Note that this only occurs when running the application from autostart. When the application is run regularly deiconify and other methods work as expected. The gtk_windows_hide method is not affected.

This is on Unity 3D Ubuntu 12.04 am64, 11.10 am64, python 2.7 / pyGTK.

I think the GTK doc clearly mentions that the iconify function can often get blocked by the window manager, something which was considered normal in GNOME2 too? So it's dependence should be restricted, no?

[Takkat (takkat-nebuk)]

As it is true that the window manager can iconify or deiconify windows:

http://developer.gnome.org/gtk/2.24/GtkWindow.html#gtk-window-iconify

Thus we can not rely on iconification. However this should not affect deiconification or the window manager's capability to deiconify (e.g. by click on launcher). Note that the observed behaviour only occurs after run from autostart and did not appear in GNOME2 or Unity before 11.10.

It would be good if Unity displayed a indicator for windows that are iconified.

This seems to be what the patches that get added to things like gtk-recordmydesktop do.

Is this still happening? Can you provide a simple app to test it?

[Takkat (takkat-nebuk)]

yeah the issue still exists in both, gtk2 and gtk3 tested on 12.04 (gtk
2.24.10 and 3.4.2), and 13.10. (gtk 2.24.20 and 3.8.2).

The issue now is consistent, i.e. not only when run from autostart as
stated above.

Test case:

#!/usr/bin/python
from gi.repository import Gtk as gtk
# import gtk

window = gtk.Window()
window.connect("delete-event", gtk.main_quit)
window.show_all()
window.iconify()
# window.deiconify()
gtk.main()

1. On 12.04 we can not open the window from the Launcher icon.
2. On 13.10 we are able to deiconify from the Launcher as expected.
3. If we called deiconify() from the app the window will have no
decoration (12.04 and 13.10)
