A few posts back I bemoaned the upgrade process from Qt3 to 4. Having completed it some time back, I now wonder what all the fuss was about. Qt4 is great! Form subclassing using private inheritance works well, the form designer is cleaner, integration with KDevelop is very good, and generally the whole toolbox has a better consistency and logic to it. There are a few widgets that I have not transferred over completely, deeming it not worth the effort, so the Qt3 support libraries are still being linked into a few modules. All told though I am happier with this new Qt, and it is full steam ahead with programming!
