    Hi all,

    I'm testing some Qtquick and qt gui apps and deploying them to the raspberry.
    I've followed beginners guide to make cross-compilation enviroment. Why always apps are shown on fullscreen mode?

    thanks

      How do you show the widgets/ QWindow? With ::show() or ::showMaximised() maybe?

        I don't use showMaximised() or showFullscreen().

        MainWindow w;
        w.show();

          Hm, then it's probably the window manager. Are other apps opening in fullscreen, too?

            No, I only have LXTerminal opened and it is not in fullscreen, I open midori and it is not opening in fullscreen.
            It only happens with QT deployed apps.

              As far as I know OpenGL on the Pi requires the application to be fullscreen. Maybe this hasn't changed yet.

                Is it using the eglfs QPA plugin? If so that is why.

                      If your app is not using OpenGL and you are running X11 on the Pi, switch to the xcb platform plugin.

                          It's possible that the platform plugin being used was built independently of the Qt configure.

                          QString QGuiApplication::platformName() will tell you what the application is using.
