I think its at the GtkWidget level
something like gtk_widget_queue_draw()
and than your widget will recieve a signal
(expose ?) in the next g_main_loop itteration.

I have created a GtkWindow, with a horizontal box in it. In the first cell
of the box, there is a drawing area containing one pixbuf. In the second
cell there is a spinbutton.
The pixbuf is to be used as a brush (This window is a preview of the brush),
the size of which is dictated by the spinbutton.
I have successfully connected a signal to the spin button so that the brush
size is changed and the pixbuf is redrawn appropriately. However, I cannot
seem to get the drawing area to refresh.
The expose event on the drawing area is working fine - I can move the window
behind another, and when I bring it back to the front, the new brush is
shown. I need it to do this as soon as a value is changed on the
How do I get the spinbutton to generate an expose event or tell the drawing
area to refresh itself?
