Hi Reiner,

I don't think that you should derive a class from TFrame to do this.
I suggest to create an object MyFrame *frame and do frame->Draw() after
having drawn your TGraph(s).
Your class MyFrame should have a function MyFrame::DistancetoPrimitive
implemented calling the TFrame ::DistancetoPrimitive.
MyFrame does not need any other function implemented.
