[vtkusers] Rectangular selection widget

[John Platt]

Hi Users,

 

Has anyone got a widget that can be used to select a rectangle in
display coordinates in a render window? The idea is to use the widget to
change the selection window in vtkSelectVisiblePoints. Basically,
vtkScalarBarWidget without the scalar bar and stickiness.

 

Many thanks.

 

John.
