KDE3

Information in this section should be used with care, as it was not written for the current version of Trinity. However, much of it still applies. If you know of any other interesting KDE3 documentation or tutorials, please add them to this section.

• KDE 3.5 API Reference

The original API reference, at kde.org

• KDE3 Architecture

The architecture pages detail how everything was originally supposed to fit together. Ported from the KDE wiki.

• KDE3 Tutorials

On everything from using kdevelop to writing dcop-aware applications to creating window themes. Ported from the KDE wiki.

• KDE3 Filesystem Hierarchy

Ported from the KDE wiki and verified against a working KDE3 instance.

• KDE3 Compilation Requirements

Mandatory and optional packages for building KDE3, most of which are still used by Trinity.

Books

C++ GUI Programming with Qt 3

Blanchette, Jasmin & Summerfield, Mark. (2015). C++ GUI Programming with Qt 3. (ISBN 0-13-124072-2)

Things to note:

• Names changed from "Qt..." to "TQt..."
• compiling by hand needs something like g++ a.cpp $(pkgconf tqt --cflags --libs) -lstdc++
• qmake -project ... will not include the TDE folders, so you'll have to add them manually to the *.pro file
• When in doubt check against the TQt API documentation
