Hi Mathias, I haven't dived into reviewing this submissions yet as I still haven't decided what the best route to take is. This week I'm moving towards having a dedicated osgQt utility library that would have various integration classes. It would seem like your QFontImplementation would be a candidate for this, as would the code in osgQtBrowser for webkit integration. There is also the sticky issue of a Viewer/GraphicsContext/QWidget integration of some form.
I have a little experience with Qt, but I'm far from an expert, so I could kick things off such as by refactoring your submission and osgQtBrowser, but it'd be very useful if the community could come together to address the more awkward parts such as how best to implement viewer integration - we have several integration examples but none work fully in all situations. Does this sound like a good plan? Will you be able to help provide some Qt expertise to get the lib in shape?
