[vtkusers] How to connect vtk mouse interaction class with QT UI

[Alex Malyushytskyy]

As far as I understand before getting renderer you have to add ( at least one ).

you may check with
this->ui->qvtkWidget->GetRenderWindow()->GetRenders(); and check
number of them in collection if you want,

If you need just one renderer you might create one and add
(AddRenderer ) one in constructor.

Your code in green is pure black box for me.
I failed to understand what you were trying to get there.
As far as I can see ClientData is not a member of this class and not
defined anywhere so result of compilation is predictable.
