Render Qt Quick to FBO
I would like to render Qt Quick/QML 2.0 directly to a FBO and use that as an overlay over a 3D scene in a QGLWidget. As it is not yet possible to mix QQuickView and QWidgets, that is my best option as far as I can see.
How can I achieve this? I see QQuickWindow has a setRenderTarget(QOpenGLFrameBufferObject*), but how can I load a QML file and render it to a FBO without ever showing the window to screen?
Are there any code examples/tests that show how to do it?
I've tried to search for this, but I only found a code snippet using QQuickCanvas, but it seems that QQuickCanvas is not available in Qt5. Is that right?
Could you post the code snippet using QQuickCanvas? I'm also trying to render Qml to a FBO.
