Resize main window and widgets inside it on screen/monitor size change

  • My MainWindows is subclassing QMainWindow.
    I have multiple monitors. My mainwindow and widgets inside the main loose their aspect ratio after moving from one screen to other.

    How can I resize my main window according to new screen size while maintaining the aspect ratio?

    I tried following this, it didn't help in my case.

    Thanks in advance.
