That doesn't look like the right API to use with Qt 5 in WebCore. In fact this shouldn't even compile. I distinctly removed QtOpenGL and QtWidgets from the WebCore build a while ago. Maybe it somehow came back. QtOpenGL is linking against QtWidgets, which I don't want to re-introduce as dependency here.

The right API to use would be either low-level QPA or a QWindow with OpenGLSurface as surface type.

Good point. I'll figure something out :)

btw this code is copied from PageClientQt, code that runs with Qt5+WebKit1...
