How to make a window always on top of all windows, including the taskbar?

I'm trying to make a system tray app with a small transparent window that will sit on top of the taskbar on Windows, like this:

I've created the transparent window, but how can I make it display always on top, even over the taskbar like the example above?

Hi
Did you try with this->setWindowFlags(Qt::FramelessWindowHint|Qt::WindowStaysOnTopHint); ?
sometimes also Qt::Popup is useful.

If it will stay above the task bar, depends on the Windows Manager used.
