Your latest description sounds like a different problem than the one I
understood and tried to help you with. Am I right that your actual
problem isn't just to redraw the widget *immediately* but rather to
redraw the widget with a changed appearance *at all*? In this case for a
GtkHScale? So your problem is actually "how to change the appearance of
a GtkHScale" and not "how to immediately redraw a widget"?
