I don't know if this still applies on GTK3 but on earlier versions ISTR 
that display widgets (like progress bar) usually aren't sensitive to 
mouse events because they have no reason to be. On X11 that also means 
they don't have the necessary X type. You have to wrap them in an event 
box and hook up to that instead.
