The KDE programming environment (APIs, documentation, conventions) is quite impressive. After having played around with konqueror (which is an impressive application in itself) I decided to have a glance at how KDE itself has progressed since I last had a quick look (1.x somewhere). It’s still a shame about the use of Qt. I know that this is a good library and that it’s free for the development of free software for X11, but that’s still not absolutely free.
