    Sorry, I forgot to add OSX to the list and thats what my tests have been on my MacBook Pro running OSX High Sierra version 10.13.6

    I accept what you are saying with respect to Android and iOS, but the isn't one of those.

    Please download the same example code as posted in the link by mrjj, report back with OS version and Qt version if you find anything different...

    Hi
    Sorry should have mentioned it.
    The samples are directly available in Creator with a normal install.

      The point is Qt is supposed to be multi-platform, I don't have a Windows PC or Linux, only Mac's and clearly it doesn't appear to work.

        Well not all hints are supported on all platforms.
        The name is often a give away
        like Qt::MSWindowsFixedSizeDialogHint
        Note the MS in front.
        or like X11BypassWindowManagerHint which is for linux / X11
        Its mention here.
        http://doc.qt.io/qt-5/qt.html#WindowType-enum

        The MSWindowsFixedSizeDialogHint do work on Windows.

          Sorry, for a product as mature as Qt this isn't what I would expect, I know this kind of thing is perfectly possible, just Qt doesn't currently work correctly.

            Well it depends on platform and the Windows manger in use.
            Some combinations are not possible in Windows either.
            Also some windows mangers on linux also ignore certain Hints.
            You are aware that Qt does not draw the decorations by its self ?
            Its handled by the OS and might not offer any way to apply it
            and Qt would have to resort to custom drawn decorations.

              The fact that it can be done using Xcode means its very possible go do, if Qt didn't rush out quite so many versions, the quality control would be better and the releases more functional.

              I'm a big fan of Qt and have used licensed versions of Qt for defence applications, licenses are not cheap and considering the money involved i would be a seriously disappointed by this show stopping lack of functionality.

              In less than 2 years I've seen Qt go from 5.1 to 5.11 and still going, releases seem to come out very frequently, which is good in one sense but at what cost?

                Well i can relate to that. Personally i would rather have more
                QWidgets/Desktop than 3D and QML/Mobile but
                the commercial side of Qt must try to focus on the marked
                trends.

                  Qt 5.1 was released 5 years ago in 2013.

                    @SGaist , ok, still a lot of releases in a short space of time, the functionality I'm trying to use is very fundamental...shouldn't that be addressed?

                      @SPlatten As @mrjj said window decorations (including the close/minimize buttons) are NOT handled by Qt. Those are handled by the OS. And different OSs are different here (even different window managers on Linux differ here). You can still do this using native APIs.
                      If you think this should be part of Qt you can file a change request.

                              @jsulm , if you can see my first posts I am OR'g in Qt::CustomizeWindowHint with each bit. I will try the WindowFlags example as I cannot guarantee that I did the same when testing with that.

                                There is sum good news and some strange findings, I am running the WindowsFlags example on my macBook Pro.

                                The setup is as follows, from the Type radio buttons, the Window is checked. From the Hints checkboxes, Customize Window is checked.

                                With no other checkboxes the window appears with no title and no widgets, it isn't resizable.

                                With 'Window minimize button' checked, the title is visible and only the minimize widget is visible.

                                If I then enable 'Window maximise button', the maximise widget is enabled along with the minimise widget.

                                If I enable 'Window close button', the close widget is enabled

                                Toggling 'Window Title', 'Frameless window', or 'Window shade button' have no effect.

                                Kind Regards,
                                Sy
