How can I keep the text 100% opacity while in a semii-transparent container? <Grid x:Name="LayoutRoot"> <Border Background="red" O...

I am trying to create an app in Qt/C++ with Qt4.5 and want the any active windows to change opacity on a mouseover event... As i understand it, there is no explicit mouseover event in Qt.

Is it really true that Crystal Reports does not support images that have transparency? We are using it at work and the guy that does Crystal Reports told me it doesn't support transparency. I couldn't believe it so I've spent the last 20 minutes googling and think he might be right. This seems absolutely incredible in this day and age....
