[Paraview-developers] Adding toggle to turn on/off interactions with 3-D widgets

[Stanton, Eric T]

Hello--

My customers have a need to be able to turn on/off mouse interaction
with 3-D widgets in ParaView. When doing analysis using box widgets that
requires precise placement, for example, they find it too easy to
accidentally rotate/scale the box widget when they meant to do so for
the entire model. 

I'm proposing adding a checkbox to the 3D widget interfaces in ParaView
(vtkPVBoxWidget, vtkPVSphereWidget) as well as a keyboard accelerator
't' to turn on/off mouse control over the widgets' size. If the former
seems too intrusive to the ParaView code, the latter would be
sufficient. vtkBoxWidget would also need to be modified to check the
state of a flag to determine whether it should be allowing interactions
to the widget or not.

Is this something other people would find useful, or no?

Thanks,
