Hello Qt Devs/Users, I'm evaluating the porting of an OpenGL based application from Qt 4 to Qt 5. I'd like to introduce QtQuick 2 Controls usage, so I have some concerns on Windows/ANGLE.
Suppose the application uses it's own non-Qt based rendering engine, which scales from OpenGL 1 to OpenGL 3.x and uses a number of extensions. Since Qt requires OpenGL 2.x but the application should run also on GL 1.x, the obiouvs choice is compiling Qt with ANGLE support. -- The question is: is it possible to embed somehow a native OpenGL window inside a QtQuick 2 view compiled with ANGLE support? (the native GL context is eventually created with OS APIs). Another drawback I see in this approach is that ANGLE excludes any QtOpenGL + OpenGL mixin, which I'm using to simplify some GL operations after the native GL context is created. -- Apart the doubts, If I can give my two cents, I'd propose some enhancement that would make this scenario (native OpenGL rendering + QML) work better: - Make it possible that ANGLE usage is choosen at runtime , instead of compile time. - Another good option would be enabling this ANGLE/Native selection on a per-context basis. This would allow using ANGLE only for QML and eventually not for native QGLWidgets. Anyone with experience on this? Thank you Qb
