Compilation of Qt would fail even with the presence of the MSYS shell sh.exe in the PATH. This caveat, has over the years, resulted in very many user complaints including this, this, this, this, this and not […]

I’ve been working on a lot of things at once over the last week but I just remembered that I never mentioned something that I should have. In the beginning of the Qt 4.3 development phase I added a class called QSvgGenerator to QtSvg. QSvgGenerator is a paint device, meaning you can open QPainter on […]

More on WebKit Qt

Posted in Aggregated

Two days ago Lars and I sat down and did the initial implementation of classes which will represent the public API for the Qt/KDE version of WebKit. In KHTML almost everything has been handled by KHTMLPart. We’d like to avoid having one huge object that does everything this time so we went with similar abstraction […]
