[vtkusers] Applying boundary to a vtkBoxWidget

[Anders Strand Vestbo]

Dear vtk-users,

I am investigating the possible usage of a vtkBoxWidget as a kind of 
Volume-Of-Interest tool for interactively selecting regions within a 
volume. I would like to be able to "constrain" the movement of the 
vtkBoxWidget to a certain volume, i.e. such the user should not be able 
to move it outside this volume. Does anyone have any idea how this can 
be done? Is there any way of setting a "movement" boundary of actors in vtk?

Any help would be highly appreciated!

Kind regards,
Anders Vestbo
