Hello Everyone,

I am trying to figure out how CreateAlphaMask method of Image widget works.

I have tried using code from "Taking a look at SWT Images" (can't post links yet) - "Single alpha value" to see if Image widget will react if I comment out CreateAlphaMask method, but there is no reaction at all.

Can someone give me a piece of code that reacts on changes made inside Image: CreateAlphaMask method, so i could see how it works ?

Any help is appriciated.

Anatoly

I understood why I was unable to see CreateAlphaMask - I am using Linux and CreateAlphaMask is not used when Cairo is used.

So problem solved Smile
