thanks for your help

gtk.drawing_area spec says :
---------------------------------------------------------

--  * Connect it to "button_press" and "button_release" events, when you want
--    it to react to user input. Note that you need to set up the event mask
--    with a call to Gtk.Widget.Set_Events.
---------------------------------------------------------


so i dont understand why my call to connect doesn't work
