[win32] desktopcover: gdk_property_get not implemented

[Johannes Sasongko]

Enabling the Desktop Cover plugin in Windows produces a warning:

  C:\exaile\xlgui\guiutil.py:109: GtkWarning: gdk_property_get: Not implemented
    return rootwindow.property_get(workarea)[2][2:4] # W,H

and sometimes followed by an error:

  Traceback (most recent call last):
    File "C:\exaile\xl\plugins.py", line 124, in enable_plugin
      plugin.enable(self.exaile)
    File "C:\exaile\plugins\desktopcover\__init__.py", line 63, in enable
      DESKTOPCOVER = DesktopCover()
    File "C:\exaile\plugins\desktopcover\__init__.py", line 118, in __init__
      self.update_position()
    File "C:\exaile\plugins\desktopcover\__init__.py", line 181, in update_position
      workarea_width, workare_height = get_workarea_size()
    File "C:\exaile\xlgui\guiutil.py", line 109, in get_workarea_size
      return rootwindow.property_get(workarea)[2][2:4] # W,H
  TypeError: 'NoneType' object is unsubscriptable

(Note: I've modified some files, so line numbers may not be accurate).

gdk.Window.property_get always returns None and prints out the warning.

One possible solution would be falling back to gtk.gdk.Screen. Can you see which part exactly fails in xlgui.guiutil.get_workarea_dimensions()?

[Johannes Sasongko (sjohannes)]

Well, gdk_property_get does nothing in Win32 [1]. The PyGTK version just returns None.

Should be fixed with r4201. Please let me know if it is not.
