The extra code for using the OpenGL paint engine is significant enough to be distracting from what the examples are supposed to show. If we want to show how to use QPainter on an OpenGL widget, then we can make dedicated and documented examples for that, in the OpenGL category. And we have such examples in the Qt OpenGL module anyway. As is, the examples feel more like manual tests of the OpenGL paint engine; if we need more coverage there, then we can add it there.

Qt's painting system is able to render vector graphics, images, and outline font-based text with sub-pixel accuracy accuracy using anti-aliasing to improve rendering quality. These examples show the most common techniques that are used when painting with Qt, from basic concepts such as drawing simple primitives to the use of transformations. Documentation for these examples can be found via the Examples link in the main Qt documentation.
