Back in October of ’09, Paul announced a windowing system plugin architecture for Qt. Actually, he introduced the lighthouse research project as a port to whatever architecture you may desire. Subsequently, Morten and MBM posted about using lighthouse. Additionally, we’ve heard about some interest both inside and outside of Qt Developer Frameworks. That’s fantastic. We’re […]
