Visually Disable a Canvas

That may have been a poor heading but what I want to do is; I’ve created a custom button class in a Canvas. It has an Icon in the middle which is stored in the Icon property of my class. If I disable my button, whats the easiest way of giving my icon a disabled look i.e. fading it a bit or making it embossed with no colour.

I just make them slightly transparent in Answers.

if not Enabled then g.Transparency = 70

Cheers Tim. I never knew this property existed. Works perfect.
