See the documentation of QGraphicsView and especially setViewPort ( http://qt-project.org/doc/qt-5/qgraphicsview.html ). In Qt 5.4 you can also use a
QOpenGLWidget. It basically sets a specific widget as the output, qtwebkit can
find that widget and use the same opengl-context in case it uses one. Without
this qtwebkit would have its own widget that can mess with yours and would
still need copying over CPU to blit textures.
