This page needs a review and probably holds information that needs to be fixed.

Parts to be reviewed:

  • Update to kapidox and KF5
  • Update link to community

The KDE project uses doxygen to generate API documentation from source code.

Please see our documentation policy and tutorial.


HTML pages

Generate apidox in the KDE format using

% cd html_dir
% /path/to/trunk/KDE/kdelibs/doc/api/ --recurse \
    --doxdatadir=/path/to/trunk/KDE/kdelibs/doc/common \


  • You must type the paths in full - the script doesn't understand tilde ('~') representing your home directory. However, you can use the $HOME environment variable instead.
  • The QTDOCDIR environment variable should point to the html folder of the Qt documentation. If QTDOCDIR is not set, will try to find the documentation based on the value of QTDIR.

To generate documentation in doxygen style instead of KDE style, use

% cd source_dir
% /path/to/trunk/KDE/kdesdk/scripts/

You'll find the top-level html at ./apidocs/html/index.html Load that page into your favorite web browser, review your documentation, then edit your code accordingly.

Warnings from doxygen will be found in ./doxygen.log. Please try to fix all warnings reported by doxygen.

Man pages

Man page lovers can generate man pages using Like so:

% cd source_dir
% /path/trunk/KDE/kdesdk/scripts/ -d /path/kdeinstall/share

You can also generate man pages from Qt source code using

% cd qt-copy/src
% /path/trunk/KDE/kdesdk/scripts/ -d /path/kdeinstall/share

and then add /path/kdeinstall/share/man to your $MANPATH environment variable.

Qt Assistant

If you like to view API documentation with Qt's assistant, then you can generate the necessary 'qch' files using

Note that requires doxygen as well as qhelpgenerator from the Qt toolkit.

doxygen v1.5.7 or above is required.

To use:

% cd source_dir
% /path/trunk/KDE/kdesdk/scripts/

You should now have a file called apidocs/qch/KDE-4.2.qch in this current working directory. Copy KDE-4.2.qch some place for safe keeping.

Now, start assistant. Go into Edit->Preferences->Documentation and add the safe copy of KDE-4.2.qch into the db.
