Using QOpenGLWindow on Mac

[Dastroet]

Hi all,

we are using Qt in a project with OpenGL context. We specify OpenGL compatability as follows:

    QApplication a(argc, argv);

    //A surface format specifies several parameters about the OpenGL context we want to create
    QSurfaceFormat format;
    //Set version to OpenGL 4.5 Compatibility in order to allow execution of deprecated OpenGL functions
    format.setRenderableType(QSurfaceFormat::OpenGL);
    format.setMajorVersion(4);
    format.setMinorVersion(5);
    format.setProfile(QSurfaceFormat::CompatibilityProfile);
    format.setOption(QSurfaceFormat::DeprecatedFunctions, true);
    //Enable vsync
    format.setSwapBehavior(QSurfaceFormat::DoubleBuffer);
    //Enable depth buffer
    format.setDepthBufferSize(24);

We run OpenGL functions in a MainWindow using QOpenGL functions compatability:

class MainWindow : public QOpenGLWindow
{
    Q_OBJECT
    QOpenGLFunctions_4_5_Compatibility* f;
    \\ ...
};

void MainWindow::initializeGL()
{
    //load OpenGL functions
    f = QOpenGLContext::currentContext()->versionFunctions<QOpenGLFunctions_4_5_Compatibility>();
}

We are confident with this on Linux and Windows. But since OpenGL is deprecated on Mac OS, we are wondering what happens, if we compile and run the code on a MAC machine. Is this going to work? If not is there a way to enable OpenGL on a MAC. AFAIK OpenGL is still available on MAC but considered deprecated.

I'd be glad if anyone could elaborate on Qt's OpenGL capabilities on MAC :)

Best Regards,

But since OpenGL is deprecated

Depricated doesn't mean it is not available. You simply try to build your app and see.
