how to make sure that digikam is started only once

[Markus Spring]

Hi,

what is the best method to ensure that there is only one digikam instance
started on a computer? Is there a signal to restore/maximise a running digikam
application, that could be sent from a shell script?

Background: My father is organizing his images with digikam, but sometimes he
overlooks a minimized digikam and starts a 2nd or 3rd instance. This seems to
lead to crashes.

Thanks - Markus

Use qdbusviewer to browse the DBus interfaces available. You can get the winID
from the org.kde.MainAppliction. I currently dont know how to show a window,
seems KWin does not provide the via DBus.
