Assuming that image1 is a Gtk::Image object, this is one of the set of
widgets that doesn't have its own Gdk::Window so they don't receive
events (in order to improve performance). If you want to catch an
event on this object, you'll probably need to stuff it into a widget
that does receive events, like a Gtk::EventBox and catch the events on
that widget. See this page for more information:
