You can invalidate an area of the widget with

  http://library.gnome.org/devel/gtk/stable/GtkWidget.html#gtk-widget-queue-draw-area

or invalidate the whole widget with gtk_widget_queue_draw().

This will (eventually, not immediately) result in the widget receiving
an expose event for the invalid area.
