How do I program programs for kde?

I want to learn to program programs for kde, but where should I start? I heard a new version of kde is coming, is the language different? help

KDE is based on the QT GUI framework. The new version of KDE (currently in development) is based on QT4, whereas the current KDE is based on the older version, QT3.

You have a choice of languages - which would you like to use. probably the most flexible and powerful is to use C++ since that is the native language of QT. However, there are quite complete bindings to other languages, for example python.

I'd start by searching for a tutorial of QT in the language you want to use, and once you know about QT, start to explore the KDE libraries.

OK, thanks, I think I saw a tutorial from a trolltech or something to do with qt, maybe I should follow that.

My friend told me that I should learn C instead of c++, what should I do?

That would be a good place to start. QT is a very nice framework - it's easy to learn and extremely powerful. Another very strong reason to try it is that is it cross platform. Once you have an app written in QT, it's easy to port it to the Mac or Windows. The current KDE is not cross platform, so if you use KDE features in your program, it won't be portable. However, KDE4 (the forthcoming version which uses QT4) will be portable. It will be interesting to see KDE running on a windows box.

If you want to program for KDE, then learn C++, python and maybe ruby. C is not used very much in KDE although its the language of choice in GNOME and the Linux Kernel.

C++ is a superset of C, so if you learn C++, you're learning C into the bargain. That's probably not quite fair because C++ and C programs tend to have different designs, but if you're just interested in syntactical stuff, C++ will teach you basic C syntax.

I have a question thats related: Is OpenGL with QT possible? and will it be easily portable(more specifically to MS Windows from Linux)?

Thanks

Yes you can do OpenGL with QT. There are several examples which ship with QT4. Should be portable AFAIK.
