Help needed overriding toolbar events!!

[richiemac]

Hello again, I need to 'quickly' learn how to override some methods of the toolbar class. I'm pretty close to totally ingnorant of how I go about this so all help would be gratefully received. I know how to inherit from a base class but I don't know how to override methods and how to use my new class with the overridden methods. I specifically looking at how to override the Enabled property so that instead of getting rid of the image it just shows a new image and how to override the button click method so that the button is no longer 'clickable' when enabled equals false. If anyone could point me to some source code of how the base class goes about things I could probably work it out for myself - eventually :).
