	No exemplo da documentacao do GTK (instale o DevHelp, e' muito bom!), as
funcoes do GDK sao utilizadas; veja:


---8<---

gboolean
expose_event (GtkWidget *widget, GdkEventExpose *event, gpointer data)
{
  gdk_window_clear_area (widget->window,
                         event->area.x, event->area.y,
                         event->area.width, event->area.height);
  gdk_gc_set_clip_rectangle (widget->style->fg_gc[widget->state],
                             &event->area);
  gdk_draw_arc (widget->window,
                widget->style->fg_gc[widget->state],
                TRUE,
                0, 0, widget->allocation.width, widget->allocation.height,
                0, 64 * 360);
  gdk_gc_set_clip_rectangle (widget->style->fg_gc[widget->state],
                             NULL);

  return TRUE;
}
[...]
  GtkWidget *drawing_area = gdk_drawing_area_new();
  gdk_drawing_area_size (GTK_DRAWING_AREA (drawing_area),
                         100, 100);
  gtk_signal_connect (GTK_OBJECT (drawing_area),

	Qualquer coisa, tamos ai'.
