    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:

      private:
          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) {
          move(event->globalX()-m_nMouseClick_X_Coordinate,event->globalY()-m_nMouseClick_Y_Coordinate);
      }
      

      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.
