    What can I do to make the taskbar always on top of my window if the window is maximized and the FramelessWindowHint flag is set.
    I know that with this flag the window will always overlap the Windows task pane. How will this be avoided?

      Hi,

      Please show how you are doing it.

      Also the platform and Qt version would be useful.

        @SGaist Hi,
        I want to make a non-standard window interface.
        I just want to understand how to make sure that my window does not overlap the taskbar.
        When I turn off the titlebar and call the showMaximize () method, while the taskbar is automatically hidden, my window completely hides the taskbar.
        If you look at the Photoshop program, the taskbar is on top - I want this effect.

        Windows 8.1
        Qt 5.8.0

              You're dealing with OS features:

              • Resizing
              • DropShadow
              • Minimize Animation
              • Aero shake
              • System context menu

              Qt::FrameLessWindowHint:

              Produces a borderless window. The user cannot move or resize a borderless window via the window system. On X11, the result of the flag is dependent on the window manager and its ability to understand Motif and/or NETWM hints. Most existing modern window managers can handle this.

              With this flag you say to window manager you don't want any OS feature to apply to your window so you should implement (fake) that features which give you full control.
              If you want to save your time you could take a look at this: https://github.com/deimos1877/BorderlessWindow

                              @dxdws You're using MinGW as compiler, right?
                              Try with MSVC++ compiler.

                                But the window still overlaps the taskbar, if it is automatically hidden.

                                  Well i don't think this could be implement and it changes in each windows version.
                                  In windows 10 main window or dialogs doesn't overlap the taskbar (as also for photo shop).
                                  Try thinking for other workaround
