Whats that supposed to do (I have an idea, but thats ugly ...)

This starts a QRunnable at a negative priority (in this case the negative integer value for NewFiles) and then calls runnableStarted(NewFiles) with the enum of the started runnable.

Yeah, I suspected that - fugly as hell!

If you need different priorities, make it explicit.
