VTK multi RenderWindow and RenderItem in QML

I’m Trying to display Multi Render item in QML.
I created 2x2 grid layout with 4 rectangle and 4 Render window and Render Item, but it was displaying only one at a time.

If I try with 1 Render Window with 4 Render Items, it’s displaying the object (here I used sphere and cone as objects).

But I need individual Render window for each Render item to use different interactor.


How do I add different interactors to individual Render Items?
