I tried by scrolling the mouse wheel to change the opacity.. so , at the point of 255, it might go into that SetOpacity () function.. I gave printf statement there to track it. That is never get printed. For opacity value '0', it wont go inside, due to the default opacity value of '8', but i expected that, it should display the printf comments, while the opacity is at 255. Its not printing. I am using the gtk examples to check this. Is it using any other different layers ? could you please explain me ?
