How to place a pushbutton onto windows title bar, is it possible ?

I'd like to place some buttons at the window title bar.
Any idea ?
Thanks

Qt won't help you in that. The title bar is not part of your application, you need to use WinAPI for that and it will only work on the latest versions of Windows.

A trick can be to create a little window with my button and 'link' it with the main window + connect some slot 'windowmove' and 'windowresize' ?
Thanks
