    Default Re: [SOLVED] Detachable QDockWidget tabs

    I tried global coordinates for only MousePress and both MouseRelease and MousePress, but both cases didn't work.
    I got this warning message and stacktrace (it's too long to post here, so I attached the full stack trace).

    Qt Code: 
    1. QNSView mouseDragged: Internal mouse button tracking invalid (missing Qt::LeftButton)
    2. QNSView mouseDragged: Internal mouse button tracking invalid (missing Qt::LeftButton)
    3. QNSView mouseDragged: Internal mouse button tracking invalid (missing Qt::LeftButton)
    4. The program has unexpectedly finished.
