[vtkusers] Picking a text (label) using mouse.

[rakesh patil]

Hello,

I display a list of texts using vtkPointSetToLabelHierarchy, and passing
this through vtkLabelPlacementMapper. I am able to display the text
successfully. Now, I need to select the text (pick) and move it and place it
wherever I want, using mouse. How can this be done?

Any ideas are welcome.

Thanks
