You widget must have a window with GDK_SCROLL_MASK in its
event_mask. Then install a callback in
widget_class->scroll_event. This function will be called when wheel up
/ wheel down occurs. You can check the direction by looking at the
field scroll_event->direction. You may want to see GtkScrolledWindow
for an example.
