Yes, setViewport() will continue to work with QOpenGLWidget too.

Note that all this does not mean existing code has to migrate away from QGLWidget. It is not going to disappear. If it works, just keep using it.

Subject: [Development] QOpenGLWidget vs. QGLWidget

Greetings all,

I've just read the new features for the upcoming Qt 5.4, here:

...and I noticed this:
"Deprecated features: Qt Gui: The QtOpenGL module, that is, the QGL classes
  are deprecated since QGLWidget has a suitable replacement now."

Will the new QOpenGLWidget class be usable like the old QGLWidget, notably
as a background for a QGraphicsView? allowing to draw QGraphicsItem, even
widgets, on top of an OpenGL scene...
