Translucent background hide whole window

  • Hi,

    At first, My english is not very well, I'm sorry.
    I have a very annoying problem. Everytime I set a tranclucent background to my widget (a class that inherits QWidget), it hides completly. What I want is a single QFrame that ist on the Widget. I'm on OSX and interesting is, that I can see the window as preview in mission control (in these little rectangles with Desktop1, Desktop2, etc.), but not on the real Desktop.
    When I set the window opacity to a value that is not null, I can sea a transparent window, but then the frame is transparent, too. What can I do to fix that problem?
    @ setWindowFlags(Qt::FramelessWindowHint);
    setAttribute(Qt::WA_TranslucentBackground, true);

    Thank you

    by the way, the same code works on ubuntu.
