[Paraview] vtkBoxWidget2 RotationEnabledOff doesn't work

[Eric E. Monson]

Hello Jorge,

It's been quite a while since I dealt with widgets in ParaView, but I just thought I'd let you know that it wasn't until very recently (sometime late in July 2011) that features like disabling Rotation was actually implemented in the BoxWidget2 in VTK. The API has indicated it was possible for quite some time, but it was never really coded up for some reason.

So, the first step might be to figure out whether the version of ParaView you're building against has a recent-enough version of VTK to even have this functionality.

Good luck,
-Eric
