Dear Qt/OpenGL experts, After the return of the 0.11 StelPainter classes I am trying again to prepare the Scenery3D plugin for integration. This plugin was developed mostly by a few students with much better OpenGL knowledge than I have, but who are no longer available to me. They managed to hack around Qt4 limitations with GLee, GLU, etc, which should not be used in Qt5. I find the used functionality in the OpenGL3.2 compatibility profile.
Qt5 brings (according to docs) easier integration of advanced OpenGL functions. However, when I derive my classes from QOpenGLFunctions_3_2_Compatibility, the required calls to initializeOpenGLFunctions() in the constructors always fail. Everything else concerning OpenGL then leads to a crash. I can compile and link shaderPrograms, but even deleting the shaderProgram without ever using it causes a crash. The docs always mention dealing with the GL context and classes which are not used by Stellarium. We use the QtDeclarative module which is now declared deprecated, and has been replaced by QML and QtQuick1 [also declared deprecated], and should be replaced by QtQuick2. Does anybody know: Can I use OpenGL3.2 at all with our current deprecated classes? Do I just have to call QOpenGLContext::create() (or something else?) somewhere (where??) before a class calls its OpenGL3.2 functions? Or do we need to update the StelMainView to use QtQuick2?
