The KDE Core Functionality Library
3.5.10
All
KDE programs use this library to provide basic functionality such as the configuration system, IPC, internationalization and locale support, site-independent access to the filesystem and a large number of other (but no less important) things. All
KDE applications should link to the kdecore library. Also, using a
KApplication derived class instead of
QApplication is almost mandatory if you expect your application to behave nicely within the
KDE environment.
