No. (It will be part of the themeability support, but not now)

You can't. If you really want that kind of control, you'll have to
go back to the EventBox. It shouldn't be too hard to even duplicate
the way buttons work. (The event triggers on the release, but only
if the pointer is within widget->allocation)
But have some pity on the user. Why not just make the volume control

True. It is just getting queued for redraw. In 0.99.4 you will be able to
fix that by doing the:
thing, before going off and doing your long operation. But there is an
even easier way, that I didn't think of mentioning earlier: just call:
gtk_widget_draw (button, NULL);
Which will make the button be redrawn immediately. It has the
downside that the button will later be drawn again, from the queued
idle redraw, but that shouldn't be noticeable.
