You can try this: 
	gtk_widget_queue_resize (widget)

This is a neat hack I got from Federico (we use this in Gnumeric):
Set the backing pixmap for the window to NULL, like this:

gtk_window_set_back_pixmap (GTK_WIDGET (drawing_area)->window, NULL, FALSE);

you can use the gtk_signal_disconnect* family of functions.

but what exactly do you want to do?
