<PRE>Hi,
|
|
|
|
you should set the event mask before realizing the drawingarea.
|
|
|
|
The code should read:
|
|
|
|
><i> drawingarea = new Gtk.DrawingArea();
|
|
</I>><i> drawingarea.SetSizeRequest(700, 400);
|
|
</I>-----> // vbox2.PackEnd(drawingarea);
|
|
><i>
|
|
</I>><i> drawingarea.ExposeEvent += new ExposeEventHandler(drawingarea_expose_event_cb);
|
|
</I>><i> drawingarea.ConfigureEvent += new ConfigureEventHandler(drawingarea_configure_event_cb);
|
|
</I>><i> drawingarea.MotionNotifyEvent += new MotionNotifyEventHandler(drawingarea_motion_notify_event_cb);
|
|
</I>><i> drawingarea.ButtonPressEvent += new ButtonPressEventHandler(drawingarea_button_press_event_cb);
|
|
</I>><i> drawingarea.Events = EventMask.ExposureMask | EventMask.LeaveNotifyMask |
|
|
</I>><i> EventMask.ButtonPressMask | EventMask.PointerMotionMask |
|
|
</I>><i> EventMask.PointerMotionHintMask;
|
|
</I>><i>
|
|
</I>><i> drawingarea.CanFocus = true;
|
|
</I>><i> drawingarea.GrabFocus();
|
|
</I>><i>
|
|
</I>><i> canvas = new DamageCanvas(drawingarea);
|
|
</I>-----> vbox2.PackEnd(drawingarea);
|
|
|
|
><i> main_window.Resize(800, 500);
|
|
</I>><i>
|
|
</I>
|
|
Hope it helps you.
