This example will show how to use an external / remote UI together with DPF.
The Plugin has a shell script that calls kdialog and uses qdbus for sending values to it.
It is a very ugly way to show a remote UI (using a shell script!), but it is only to prove the point.
Note that everything regarding external UIs is still a bit experimental in DPF.
There is Unix-specific code in there.
