description
kded4 is
responsible for creating the sycoca file, i.e. the binary
cache of servicetypes, mimetypes, and services for a
particular user.
It monitors the
directories containing .desktop files. When a file is
added/removed, it waits 5 seconds (in case of a series of
updates), and then launches kbuildsycoca4 to update
the sycoca.
It checks newly
installed update files, i.e. the *.upd files used to update
configuration files of users when the configuration file
formats changes. kconf_update is launched to do the
updates.
When the
hostname changes, it will make the necessary changes to the
KDE environment and X-server to allow continued proper
operation, launching kdontchangethehostname to do the
changes.
Those tasks are
also performed always at kded4 start to ensure that the user
configuration is up to date.
It is also
responsible for launching the on-demand kded4 modules
and init enabled kded4 modules like:
