Mouse click in DisplayImplJ2D

Hi, there,

Suppose I implement a function, (x,y)->f, and display it in 2D with DisplayImplJ2D, how can I get the coordinates (x,y) as well as the range f, by clicking right button of mouse?

I notice that offers similar functionality, but it is only for 3D, in other words, I cannot do: myDisplayImplJ2D.addReferences(PickManipulationRendererJ3D, myDataRef).  Does anyone any workaround?

thanks in advance,
