I seem to recall that I originally (about 3 years ago) chose a pbuffer implementation because frame buffers were not widely supported on Windows. Is it possible to give some general advice as to the compatibility of frame buffers vs pbuffers on Mac and Windows? I see 5.0 has QOpenGLFramebufferObject. Is this considered to be widely compatible with various graphics cards? _______________________________________________ Development mailing list [email protected] http://lists.qt-project.org/mailman/listinfo/development
