[vtkusers] Problem with Callback function

[vishal]

hi,
I retified the error that i have made...
    // // Allow the observer to access the sphereSource 
         keypressCallback->SetClientData(volume); 
        keypressCallback->SetCallback(KeypressCallbackFunction ); 
        renWin->AddObserver(vtkCommand::KeyPressEvent, keypressCallback); 

the last line should actually be:
        iren->AddObserver(vtkCommand::KeyPressEvent, keypressCallback);

now the radius values are appearing BUT they are not updating after the
first keypress... I have attached the result with this mail.. please
advice...thank you
Regards
Vishal
