Why don't you make an OpenGL middleware driver? Then your application will always be an OpenGL application and the middleware driver will take all of the OpenGL calls in place of the system's driver and do the translation there? The middleware driver will then contain the ANGLE code and the application will be none the wiser.

Well, I guess it's not possible to link against the ANGLE OpenGL library and native OpenGL libraries at the same time, so maybe this wouldn't work out in practice, unless we do a lot of runtime resolving magic... Not talking about using different plugins, since QtGui itself nedes to link against OpenGL. > If so, where you planning on mixed usage (OpenGL ES2 and OpenGL 2 > usage at the same time)? Nope, just for an application to be able to explicitly use desktop OpenGL if so desired. At best we could hope to support using OpenGL ES 2 for one QWindow and desktop OpenGL for another, but definitely not mixing the two within the same context. -- Samuel _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
