I assume the drawing area is packed into a main window via some mechanism.
The drawing area must have the focus to receive key press events from the
parent. You should make sure that the drawing area widget has the CAN_FOCUS
flag, otherwise it can never receive the focus.

Subject: About drawing area's keypress event


Hi:
  Many thanks for everybody's advice.Now,I have a question.I use
gtk_widget_set_events() to probe a drawing_area's keypress event,but I
cann't get it.However I may get a buttonpress event.My codes is these below.


file://*********************************************************************
*******//
gtk_widget_set_events (GTK_WIDGET(drawing_area), GDK_EXPOSURE_MASK
| GDK_BUTTON_PRESS_MASK | GDK_POINTER_MOTION_MASK
| GDK_BUTTON_RELEASE_MASK |GDK_KEY_PRESS_MASK | GDK_KEY_RELEASE_MASK);
gtk_signal_connect (GTK_OBJECT (drawing_area), "key_press_event",
    GTK_SIGNAL_FUNC(KeyPrs_CallBack),NULL);


file://*********************************************************************
*******//

If I use window(a Gtk's toplevel window) to replace drawing_area,I may get
keypress event.How can I get drawing_area's keypress event?

Thanks!
