QVtkWidget under QTabWidget interactions are not working

[Muhammad Jawad]

Here is my code:

vtkSmartPointer<vtkImageViewer2> imageViewer = vtkSmartPointer<vtkImageViewer2>::New(); 
    vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor = vtkSmartPointer<vtkRenderWindowInteractor>::New();
    // this class is reimplemented from VtkInteractorStyleImage
    vtkSmartPointer<MyVtkInteractorStyleImage> myInteractorStyle =  vtkSmartPointer<MyVtkInteractorStyleImage>::New();
 
    renderWindowInteractor->SetInteractorStyle(myInteractorStyle);
    myInteractorStyle->SetImageViewer(imageViewer);
 
    imageViewer->SetupInteractor(renderWindowInteractor);
 
    QVTKWidget *qvtkWidget = this->ptrMainWindow->GetQVtkWidget(viewerId);
    qvtkWidget->SetRenderWindow(imageViewer->GetRenderWindow());
    imageViewer->GetRenderer()->ResetCamera();
    imageViewer->Render();
    qvtkWidget->GetRenderWindow()->SetInteractor(imageViewer->GetRenderWindow()->GetInteractor());

vtkSmartPointer<vtkImageViewer2> imageViewer = vtkSmartPointer<vtkImageViewer2>::New(); 
    vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor = vtkSmartPointer<vtkRenderWindowInteractor>::New();
    // this class is reimplemented from VtkInteractorStyleImage
    vtkSmartPointer<MyVtkInteractorStyleImage> myInteractorStyle =  vtkSmartPointer<MyVtkInteractorStyleImage>::New();
    
    renderWindowInteractor->SetInteractorStyle(myInteractorStyle);
    myInteractorStyle->SetImageViewer(imageViewer);
    
    imageViewer->SetupInteractor(renderWindowInteractor);
 
    QVTKWidget *qvtkWidget = this->ptrMainWindow->GetQVtkWidget(viewerId);
    qvtkWidget->SetRenderWindow(imageViewer->GetRenderWindow());
    imageViewer->GetRenderer()->ResetCamera();
    imageViewer->Render();
    qvtkWidget->GetRenderWindow()->SetInteractor(imageViewer->GetRenderWindow()->GetInteractor());

When I use QVtkWidget as a mainwindow child then the interactions are working perfectly. But, I need to put three QVtkWidgets. So, I used QTabWidget inside mainwindow and put three QVtkWidgets in multiple tabs of QTabWidget. It load the data, but the interactions become jam.

Any help.

Sorry, but I don't know enough about vtk to help. Doesn't Kitware have a forum for vtk? You might be better off to post your question there.

But I think, this is not the problem at vtk side. It may be more on Qt side. But any way thanks for your time.
