Just call this function everytime you want to refresh the drawing area.
(assuming that you have "expose_event" connected to the drawing function)

-------------
void drawing_area_draw (GtkWidget *drawing_area)
{
GdkRectangle area;

area.x = 0;
area.y = 0;
area.width  = drawing_area->allocation.width;
area.height = drawing_area->allocation.height;

gtk_widget_draw (drawing_area, &area);
}
