Besides serving as an example for performing OpenGL rendering inside a window container in a way that it works across all GL versions, this is an extremely useful tool for developers and users alike since it allows quick and easy checking of what sort of context a particular driver returns for a particular QSurfaceFormat. NB! Depending on the OpenGL driver, some surprises can be expected. The handling of core/compatibility profiles, the fwdcompat bit, the supported GLSL versions, etc. tend to be somewhat different across the different OpenGL implementations.

Qt provides support for integration with OpenGL implementations on all platforms, giving developers the opportunity to display hardware accelerated 3D graphics alongside a more conventional user interface. These examples demonstrate the basic techniques used to take advantage of OpenGL in Qt applications. Documentation for these examples can be found via the Examples link in the main Qt documentation.
