[vtkusers] Question on vtkDistanceWidget

[Alex Malyushytskyy]

I believe you can get distance from presentation :
GetDistanceRepresentation () -> GetDistance();

vtkDistanceRepresentation::SetLabelFormat 	( 	const char *  		)
might help you to specify the way text is displayed.

Something like
GetDistanceRepresentation () ->SetLabelFormat 	( 	" D1 = %s") ;
should work.
