transparent area hit testing

clicking 100% transparent area doesnt activate the window

August 9, 2006 12:08 AM from

I'm working on an open source 'aero' skin and noticed that when I click on a completely transparent area of a windows border, it doesn't activate that window. Is this intended? I was going to make buttons with part of the glyph being completely transparent. This will definitely change my design.

That is perfectly normal. If the window is 100% invisible at any point then that point cannot be selected.

A possible solution would be to make the alpha set to 1 instead of 0. Then you can click it but it will be almost invisible still.

Thanks. I thought about that an hour after posting. There's not a visible difference and the hit testing works as I expect.
