a pixmap is not a window. even if had a signal such as "clicked", it
could not generate it because, having no window, it will never be
recipient of the "lower level" X/Gdk events that eventually may lead
to a "clicked" being sent.
you need to put the container into an event box, and set the events
for the event box to include BUTTON_RELEASE_MASK, and connect to
"button-release" of the event box.
"clicked" is a special signal that as far as i know only buttons
generation.
