Maybe there is really no (public) API to just get the QKeySequence, as defined in the KDE settings dialog, because to my understanding KDE applications just need to bother about the proper KAction instance, which for standard actions is easily instantiated via:

  http://api.kde.org/4.0-api/kdelibs-apidocs/kdeui/html/namespaceKStandardAction.html

And I guess the corresponding shortcut is properly set according to the user settings respective the HIG recommendations.


As a proof of concept, a naive "user settings aware" Qt implementation could be

- When initialising QApplication and
- When we detect running on KDE
- Dynamically link to "KDE Core" library (if not already done so anyway)
- For each standard QKeySequence:
  * Instantiate the corresponding KAction via KStandardAction
  * Get the shortcut (QKeySequence) set for the KAction and initialise the standard QKeySequence in Qt with it


Off course instantiating n objects just for getting a shortcut is totally nonsense, let alone that linking against a library (KDE Core) which on its turn depends on Qt itself is not such a brilliant idea...

Heck, but via clever plugin mechanisms Qt also manages to call the standard KDE file dialog today, so I'm pretty sure there is a way to query the KDE shortcut settings, too, in some way :)
