    what if the file doesn't exist? I would just use a QTemporaryFile to create a file and try to overwrite it.

Indeed, on closer investigating it appears that there is no way to even explictly force an overwrite check when using the KDE platform theme, because of this code in plasma-integration/src/platformtheme/kdeplatformfiledialoghelper.cpp:

This is also a sensible default to have from the user's point of view.  This change does that in the platform theme plugin, for all saving operations.
