org.kde.notifications settings via qtscript

[Dennis Knorr]

Hi,
i was pointed here with my plasma/desktop configuration issue.
I want to set a certain configuration item for the notifications via
qtscript.
I tried to access the systemtray widget and access from there the applet
for org.kde.notifications. But this did not work.
Any idea how to set configuration-parameters for org.kde.notification?
I did read the PlasmaDesktopScripting Tutorial, but it didn't help.

Thanks,
Dennis
