I first tried to use glGetString() from main after the compositor creation but that should be a different thread than the rendering thead: https://github.com/hawaii-desktop/greenisland/blob/master/src/greenisland/main.cpp Then I tried to connect the signal on the QQuickView subclass constructor to a private slot. The slot should be called from the rendering thread, giving me access to the context but it doesn't seem to happen. -- Out of the box experience http://www.maui-project.org/ _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
