    Hi @sehnkim ,

    AFAIK, Some one can't force the title bar font from the Qt as Mr. @SGaist said . It's completely from the desktop settings. You can change this from the Desktop settings . if your are really worried about the font size. But the problem is. the desktop setting will be applicable to all windows on Windows.

          Hi
          sadly dragging images to forum post is bugged. we cant see the image.
          Please use external site such as postimage.org (or what u prefer)

          About drawing Title bar or borders:
          This is called decorations and is beyond Qts control. As already stated it's
          not really possible in any platform neutral way.

          So the only solutions is to
          1: make a fake windows widget and draw caption and implement dragging etc.
          This is a road of pain as if to be used as a Mainwindow it will show some of its fake nature in
          various aspects of the OS.
          2: use native SDK
          This covers it ok and also discuss Win native api calls to use to make possible.
          https://forum.qt.io/topic/3258/how-to-draw-to-the-windows-title-bar-with-qt-is-this-possible
          Note that this will ofc not work on linux etc.

            Thank you so much @Ni.Sumi and @SGaist

            May I ask you one follow-up question?
            As shown in the attached picture, I need to change the color of the title bar (refer to the green arrow) and the color of the border line (refer to the red arrow) of the main window.
            I am not sure if I can change them or not. Any comments would be really appreciated.

            Thanks a lot.

              You might be able to do that with some native API on Windows but I haven't tested them. This article might help you get further

                Hi,

                The title bar is handled by the window manager not by Qt so it's not something you can modify within the app by default.

                @SGaist so we can't customize the title bar of the application window of QML?

                  @Vijaykarthikeyan Qt does not manage window decoration. That's the OS that does it.
