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. > > In any case: Did you look at gdk_display_put_event () with a > GdkEventButton?

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. > -- > Michael C.

Random memory allocation error

RE: Random memory allocation error
Nailed it on the head. bad programing. I forgot how wonderful valgrind is, thanks.
