Testing a platform's OpenGL capabilities

[Wieland]

Hi,

in the Scene Graph-Rendering FBOs in a thread example the platform's support for threaded OpenGL is tested like this:

QGuiApplicationPrivate::platform_integration->hasCapability(QPlatformIntegration::ThreadedOpenGL))

As one can see, this involves including private qt features. As the example is around for some years (months?) now, I thought that in the meantime stuff might have been added that offers the same functionality without the need for private qt features to be included.

Any ideas?

Hi,

What OpenGL capabilities do you have in mind ?

[Wieland]

First I need to know if desktop OpenGL is available or only OpenGLES. If the system has support for desktop OpenGL then the next thing I need to know is, if threaded OpenGL (like in my post above) is available.

Would "QOpenGLContext::OpenGLModuleType":http://doc.qt.io/qt-5/qopenglcontext.html#OpenGLModuleType-enum fit for the first part ?

@SGaist Great! Thank you! Didn't know this exists. :-)
