Hi, by default all well-known applications show in history.
Having DesktopEntry= in the notifyrc should make it show up in System Settings. Make sure the notifyrc file is intsalled in the correct location and the DesktopEntry matches the desktop file name and that the desktop file isn't marked as Hidden etc.
Also, applications that aren't properly registered like above but have sent a notification once will be registered and show up in the list.
Make sure the desktopFileName in the QApplication/KAboutData is set correctly. Check the "desktop-entry" hint of the notification emitted by KAlarm using dbus-monitor if necessary to find out if it sends the correct hint.
Cheers Kai Uwe
