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

[Xiaopeng Yang]

Alex and David,

Thank you for your reply. Sorry to make you confused about my question. The
first error is that "'ui' : is not a member of 'MouseInteractorStylePP'".
That's why I am asking how to connect the mouse interaction class with QT
ui.

The second problem is that if I would like to call addPoint() within the
mouse interaction class, how to fulfill this? 

Thank you very much.

Best,
Xiaopeng

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.

Alex
