It seems that internally KTempFile only has one default path, but also allows 
the user to specify a directory (well, rather it interprets the "name" as a 
path prefix rather than a template name a la QTemporaryFile).

I know you're no longer among the trolls, but since you asked, a constructor 
that was the following would seem to get around this issue:

QTemporaryFile(const QDir &dir, const QString &templateName)

...potentially with the other constructors doubled as well.

There are a handful of other methods(file(), textStream(), dataStream()) that 
are widely used, but still possible (if more cumbersome) with the Qt 4 API.

Whether a wrapper class would still be justified is debatable.
