Check, and I think you'll find you get exactly one event
with:
event->type == GDK_BUTTON_PRESS
for each event event with event->type == GDK_BUTTON_RELEASE.
You are just getting more events with type
GDK_2BUTTON_PRESS, and GDK_3BUTTON_PRESS.
(For a double click, gdk sends:
GDK_BUTTON_PRESS
GDK_BUTTON_RELEASE
GDK_BUTTON_PRESS
GDK_2BUTTON_PRESS
GDK_BUTTON_RELEASE)

Owen
