The API is available by including qopenglcontext.h as usual,
but scoped in the QPlatformInterface namespace. The namespace
exposes platform specific type-safe interfaces that provide:
a) Factory functions for adopting native contexts, e.g.
QCocoaGLContext::fromNative(nsContext, shareContext);
b) Access to underlying native handles, e.g.
openGLContext->platformInterface<QCocoaGLContext>->nativeContext()
c) Platform specific functionality, e.g.
static QWGLContext::openGLModuleHandle()
openGLContext->platformInterface<QEGLContext>->doSomething();
The platform interfaces live close to the classes they extend,
removing the need for complex indirection and plumbing, and
avoids kitchen-sink modules and APIs such as the extras modules,
QPlatformFunctions, or QPlatformNativeInterface.
In the case of QOpenGLContext these platform APIs are backed
by the platform plugin, so dynamic_cast is used to ensure the
platform plugin supports the requested interface, but this is
and implementation detail. The interface APIs are agnostic
to where the implementation lives, while still being available
to the user as part of the APIs they extend/augment.
The documentation will be restored when the dust settles.

README
Qt is supplied with a number of example applications that have been written to provide developers with examples of the Qt API in use, highlight good programming practice, and showcase features found in each of Qt's core technologies. Documentation for examples can be found in the Examples section of the Qt documentation.
