[vtkusers] Hi, question in VTK renderwindow

[Hui Zhang (James)]

Hi,

Currently my program has several vtk window attached to FLTK widgets. Just a
question, how could I prevent vtk to render or update these windows? All or
part of them?
For example, four vtk windows A, B, C, D. What I want to do is prevent A and
B from updating and rendering, even I click or drag mouse on it, while
window C and D is working normally?

Thanks
James
