ContextMenus

Dear Rooters,
I have:
class ControlGraph : public TGraph ...
..
public:

   SetFactor(Int_t point_number, Float_t factor); // *MENU*

If a point on the graph is clicked with the right mouse the menu pops up with "SetFactor" being in the list.

Now my question:
Is there a way to find out (in SetFactor) which point is clicked or as an alternative px, py of the point?

Cheers
Otto
