Well I'am creating to create a game sovler. Once my window is placed
over the grid of the game, the application starts to take shots of the
display, and move the mouse and clicks over the grid depending on the
content of the shot.

I'm reading its documentation right now, but it seems not work even
tought it's possible I'm using it wrong. Indeed when I create an event
I should insert the window which is going to receive the event: what
is it in my particular case? is the gdk_display_put_event going to
override this field inside my event object? Here is the code I'm
trying (python):

 def fake_button_press_event(self, x, y):
   event = gdk.Event(gdk.BUTTON_PRESS)
   event.x = 500.
   event.y = 500.
   event.button = 1

   gtk.gdk.display_get_default().put_event(event)


Thanks in advance.
