anyone tell me what vital (and likely obvious) operation I've failed

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.
