Note that a VBox doesn't get any expose events as it doesn't have any "drawable area" (I forgot the proper name for its classifaction). To get expose events pack the vbox into a GtkEventBox. You can then set the background of the GtkEventBox.

I'm not *entirely* sure, but maybe the solution is to make sure that
after your expose-event handler gets called, the default expose event
handler gets called. If my guess is correct, then your expose-event
handler is either being called *after* or *in place of* the ordinary
expose-event handler which draws its child widgets.

Perhaps then another solution might also be to invoke similar
expose-events upon the child nodes of your VBox?
