This is really a GTK question. Rhythmbox doesn't provide any specific
means to do this. Anyway, it depends on what exactly you're trying to
do. If you want to catch middle-click events in specific widgets, you
can probably connect a button-click-event or button-release-event
handler for those widgets. If you want to catch middle clicks anywhere
in the whole application (which doesn't sound like a great idea to me,
but whatever), you might need to use gdk_window_add_filter instead.
