Re-invent Your Desktop with Plasma!
There's so much more to say about Plasma and its technologies, but I'm out of space. The Resources for this article include many useful references to help make your desktop (or whatever your Plasma is running on) a better place.
Complete Qt documentation, with tutorials and examples is at doc.qt.nokia.com.
The full KDE API documentation is accessible at api.kde.org.
TechBase, a wiki for KDE developers can be found at techbase.kde.org.
Another great introductory tutorial is techbase.kde.org/index.php?title=Development/Tutorials/Plasma/GettingStarted. All other Plasma tutorials (including tutorials for non-C++ languages) are at techbase.kde.org/index.php?title=Development/Tutorials/Plasma.
The KDE examples module, a new KDE module released with KDE 4.4, contains example code, including (but not limited to) Plasma plugins. Your distribution should have packages available, but if not, you can browse the SVN repository via websvn.kde.org/trunk/KDE/kdeexamples, or you can download a tarball from ftp.kde.org/pub/kde/stable/latest/src.
The full source code for the applet described in this article is available at ftp.linuxjournal.com/pub/lj/listings/issue190/10638.tgz.
You can contact the Plasma developers and applet writers via the mailing list email@example.com, or by joining the #plasma channel on the Freenode IRC network. Don't hesitate to contact us if you need some help!
