The glColorMask call was troublesome. In addition, the Qt::WA_TranslucentBackground was misinterpreted and recommended misleadingly in the documentation. The hellogl2 example's --transparent argument was disfunctional in practice. Replace glColorMask with glBlendFuncSeparate. The hellogl2 example and the docs are now corrected wrt enabling semi-transparency in a QOpenGLWidget that is not a top-level (which is the most common case).

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.
