Just to have a feel of this change I endorse CPP mode as the default mode fot HBQT. Later if it is not felt ok, we can always revert it. Till date I ever experimented with default Harbour builds and Qt 4.5.1 only. I never tried with later versions of Qt because of the fact that it will lead to more cheos if someone will try to use Qt 4.5 only. I would suggest, for the time being, drop Qt 4.6 support. Let it be mature enough before we make a final decision. Then I will recommend about minimum version to be Qt 4.6 which Harbour supports. Once we implement Qt 4.6 wrappers, it will not be possible to link with Qt 4.5 anyway.
