I tried to create an AppIndicator using gtk.ImageMenuItems. Normally ImageMenuItems display the stock's item, but using Python AppIndicator no Icons in the menu are displayed at all. Is this a lacking feature ?
Here is my example code. Of course the indicator displays an icon but non of the menu entries:
exit_item = gtk.ImageMenuItem(stock_id=gtk.STOCK_QUIT)
exit_item.connect("activate", quit, None)
exit_item.show()
