If you are using the main C++ distribution of wxWidgets, Feel free to ask any question related to wxWidgets development here. This means questions regarding to C++ and wxWidgets, not compile problems.
Does it still make sense to use wxGLCanvas for OpenGL rendering if I want to create a 3.x or 4.x context? Is that even supported? Or, if I would want to create my own canvas class, where would I have to start?
