Hi Dean,

Can you give me a brief idea how to do that - I don't actually have a
concrete picker declared anywhere - I just have an interactor, and
drop my plane widgets into the scene:

    planeWidget->SetInteractor(iren)
    planeWidget->SetCurrentRenderer(renderer);
    planeWidget->SetPlacement();

I was thinking I could do something like:

    planeWidget->SetPicker(iren->GetPicker());

but that doesn't work! Do I need to make my own picker or can I just
use some default one from the interactor or renderer?

Thanks,
Mark
