[newbie] Reloading KDE desktop from a shell.

[=?x-unknown?q?Pe=F1a_Arellano_Fabian_Erasmo?=]

        Hi all,

        Is it possible to reload the KDE desktop using a shell command
without restarting the X server? How does an installation program sets an
icon on the desktop? 
        Thanks in advance to all.

        Fabian.
