XSettings-KDE is a XSettings (http://freedesktop.org/wiki/Standards_2fxsettings_2dspec ) daemon, wrapping some KDE configuration paramaters for XSettings aware applications, such as most GTK+ 2 applications and GNOME 2 applications.

Currently, it allows those applications to receive instant notification of the following changes in KDE configuration :
-default font name and size
-theme name
-icon theme name
-maximum interval of time between two clicks to be considered as a double-click
-threshold to trigger drag and drop
-icon presence in stock buttons
-toolbar style (text only, icons only, ...)

This daemon is based on Owen Taylor xsetting reference implementation which can be found on http://cvs.freedesktop.org/xsettings/xsettings/
