[gtkmm] drawing area mouse events

[Milos Negovanovic <milosn xtra co nz>]

Hello,

i am trying to capture mouse clicks on the DrawingArea and so far i
managed to get it working(partially) but X&Y seems never to change:

..............................................................
//enable button press event
add_events(Gdk::BUTTON_PRESS_MASK);

//on_button_press implementation
bool Test::on_button_press_event(GdkEventButton* event) {
	printf("\nbutton: %i", event->button);
	printf("\n   x : %i", event->x);
	printf("\n   y : %i", event->y);
	printf("\n");
}
..................................................................

output is:
button: 1
   x : 0
   y : 0

button: 2
   x : 0
   y : 0

button: 3
   x : 0
   y : 0


Any suggestions? (GTKMM-2.0.2)

Regards
Milos
