[pygtk] Critical when emitting key press event

[Fabrizio Pollastri]

I am emulating a keyboard with gtk buttons. To entry some text into a 
gtk.Entry, I first set the focus on the gtk.Entry and then I press the 
buttons. Keypad input works as expected (the keypad character appears 
into gtk.Entry), but gtk complains with the following two messages at 
each button pressing.

(myprogram.py:21650): Gdk-CRITICAL **: gdk_drawable_get_display: 
assertion `GDK_IS_DRAWABLE (drawable)' failed

(myprogram.py:21650): Gdk-CRITICAL **: gdk_keymap_get_for_display: 
assertion `GDK_IS_DISPLAY (display)' failed

My code is the following.

This is the callback code for the button press event.

event = gtk.gdk.Event(gtk.gdk.KEY_PRESS)
event.keyval = ord(key_associated_with_pressed_button)
keypad_widget.get_toplevel().get_focus().emit("key_press_event",
         event)

Last row suppose that the keypad input must be directed to any widget 
having the focus in the same top level window. In my case, the widget is 
a gtk.Entry.

Thanks in advance for any help.
