[pygtk] Geting a window/dialog to appear on a different screen.

[Neil Dugan]

Hi,

I have a LTSP set-up here.  I would like to put a window or dialog on =

the client screens, but I can't seem to get this to happen I am =

getting weird errors from gtk.main().

See attachment for the code.

The errors I am getting are
/media/tmp/testgui:43: GtkWarning: gdk_screen_get_display: assertion =

`GDK_IS_SCREEN (screen)' failed
   gtk.main()
/media/tmp/testgui:43: GtkWarning: gdk_keymap_get_for_display: =

assertion `GDK_IS_DISPLAY (display)' failed
   gtk.main()
/media/tmp/testgui:43: Warning: invalid (NULL) pointer instance
   gtk.main()
/media/tmp/testgui:43: Warning: g_signal_connect_data: assertion =

`G_TYPE_CHECK_INSTANCE (instance)' failed
   gtk.main()
Traceback (most recent call last):
   File "/media/tmp/testgui", line 43, in <module>
     gtk.main()


If I comment out line 20 =

"window.set_screen(display.get_screen(screen))" all works as expected.

Any help appreciated.

Regards Neil.
