Unsolved Using QOpenGLWindow on Mac
-
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,

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