[Insight-users] How to connect vtk mouse interaction class with QT UI

[Xiaopeng Yang]

Dear Users,

 

I would like to render my qvtkWidget when I right click the mouse. But the
following code has error in the red line. Could you point out where I made a
mistake?

 

And also I would like to execute addpoint() when I right click the mouse. So
I tried the code in green line. But it also had error. Do you how to execute
addpoint by the mouse interaction?

 

 

SimpleView::SimpleView()

{ 

     this->ui = new Ui_SimpleView;

     this->ui->setupUi(this);

}

 

 

SimpleView:: addpoint()

{

}

 

class MouseInteractorStylePP : public vtkInteractorStyleTrackballCamera

{

public:

    static MouseInteractorStylePP* New();

    vtkTypeMacro(MouseInteractorStylePP, vtkInteractorStyleTrackballCamera);

virtual void OnRightButtonDown() 

{

 
this->Interactor->GetPicker()->Pick(this->Interactor->GetEventPosition()[0],


                         this->Interactor->GetEventPosition()[1], 

                         0, 

 
this->Interactor->GetRenderWindow()->GetRenderers()->GetFirstRenderer());

         double picked[3];

         this->Interactor->GetPicker()->GetPickPosition(picked);

         std::cout << "Picked value: " << picked[0] << " " << picked[1] << "
" << picked[2] << std::endl;

 

         this->ui->qvtkWidget->GetRenderWindow()->Render();  ?? Error here

         

         SimpleView *workspace = (SimpleView*)ClientData; //ClientData:
undefined

         workspace->addPoint();

}

 

Thanks a lot!

 

Best regards,

Xiaopeng
