Hi Eugen,

The rule of thumb is that Qt uses the native file dialog where one is
available. As for the English vs. German Qt will respect the machine's
locale unless you override it as you're doing here. So maybe you don't
have the qt_de.qm file on your XP machine?

You can tell Qt not to use native dialogs:
