[vtkusers] QVTKWidget existing interactors

[Drysdale, Jeremy]

David,

Thanks for the info.  One other question comes to mind... short of testing with every possible interactor available, is there a list or a decent description somewhere?

Thanks,

What you're looking for are called interactor "styles". These classes
start with vtkInteractorStyleXYZ

Here are some examples demonstrating how to use SetInteractorStyle:
