[Gtk-sharp-list] Toggled state change and events

[Scott Ellington]

If you are using regular toggle buttons (i.e. not toggletoolbuttons),
then what you can do is subclass ToggleButton and override the OnClicked
method like so:

protected override void OnClicked()
{
	// make the change programmatically that causes the button to be toggled
	// Don't call base.OnClicked() thus preventing the toggling
}

If you, like me, are using ToggleToolButton, then, as far as I know, you are out 
luck.  I have submitted a bug for this:
