[pygtk] Setting the cursor on a Combobox GDK Window

[Shandy Brown]

Hi all.

I've been struggling with how to set the cursor on the GDK Window that
pops up when you click on a combobox.  I think I need to use
get_root_window() as demonstrated in the snippet below.  This works but
I'm seeking confirmation that get_root_window() is actually returning
what I think it is.  Anybody more informed than myself care to comment?

self.comboBox.connect('realize', self._comboRealized)

def _comboRealized(self, widget):
  # The root window is the GDK Window that pops up when a user clicks
  # on the comboBox widget.  It doesn't exist until the comboBox is
  # realized, so we have to set the cursor in this special function.
  rootWin = self.comboBox.get_root_window()
  rootWin.set_cursor(gtk.gdk.Cursor(gtk.gdk.LEFT_PTR))
