Frameless window dragging issue

  • Hi everyone,
    I am developing an qt gui application and i have set the window flag to @Qt::FramelessWİndowHint@ and i have set the mainwindow stylesheet as i wanted. But i cannot move the window without the window frames.

    Is there any way to solve it ?

    Thanks in advance,

  • Add to window .h file:

        void mousePressEvent(QMouseEvent *event);
        void mouseMoveEvent(QMouseEvent *event);
        int m_nMouseClick_X_Coordinate;
        int m_nMouseClick_Y_Coordinate;

    And this to .cpp file:

    void MainWindow::mousePressEvent(QMouseEvent *event) {
        m_nMouseClick_X_Coordinate = event->x();
        m_nMouseClick_Y_Coordinate = event->y();
    void MainWindow::mouseMoveEvent(QMouseEvent *event) {

    This is quick answer. Code may grow up if you have resizing elements or problems with dragging when mouse pressed on window child elements.

  • I've not done this, but I can only imagine that you would have to provide your own code to move the window. As it is, a frameless window has no UI component with which the user can imagine that the window can be moved.

    Or is that not what you meant ?

  • Of course you need to add code for handling mouse events.
    I think it is good idea to make something like title bar for moving the window.

  • Thank you sanja1989 your code works perfectly.
