 ... obviously you mean keypress_callback...

Anyway, the drawing area does'nt catches the key_press event.

With gtk_widget_set_events (da, GDK_KEY_PRESS_MASK | 
                                GDK_BUTTON_PRESS_MASK | 
                                GDK_EXPOSURE_MASK);
and
  gtk_signal_connect (GTK_OBJECT (da), "button_press_event",
                     (GtkSignalFunc) buttonpress_callback, NULL);

gint button_press_event (GtkWidget *widget, GdkEventButton *event,
gpointer data)
{
  g_print ("button_press\n");
  return TRUE;
}

The drawing area catches the button_press event.

Any idea ?
Thanks.
