[Qt-interest] transparent widget on top of QGLWidget

[Raja Rokkam]

Do you want a transparent window or Translucent window ?

You will get an opaque black background if you setAttribute as
WA_TranslucentBackground. If you set the windows flag to
FramelessWindowHint, then you would get a translucent window and black
background will go away.
