When calling g_signal_connect the handler will be called before the
default handler, i.e. the custom drawing happens before all the other
widgets are drawn. The opposite is done by gtk-sharp when connecting
to an event. The order can be changed by using the
GLib.ConnectBeforeAttribute.
[GLib.ConnectBefore]
public void Expose(object o, Gtk.ExposeEventArgs args)
{...}
The other (recommended) way is to subclass the object and override the
virtual method for the default handler.
protected override bool OnExposeEvent(Gdk.EventExpose evnt)
{
// Custom drawing before and/or after the default handler.
// The default handler can also be ignored completely.
return base.OnExposeEvent(evnt);
}
