Goals

  • Update Slicer code base to listen to interactor instead of interactor style
  • Add support for interactor style switch per view
  • Allow access to vtkRenderWindow from vtkMRMLViewNode

Motivation

  • We would like to conveniently be able to change the interactor style without having to reset all observer for the displayable managers.
  • Accessing the vtkRenderWindow would allow us to do (for example) screenshots given a specific viewNode.

InteractorStyle management

Workaround

Access 3D View

  • Created a new Action menu in qSlicerMouseModeToolBar following this method.
  • Accessed all qMRMLThreeDView through the layoutManager
void qSlicerMouseModeToolBar::switchToTrackBallInteractorStyle()
{
  qMRMLLayoutManager *layoutManager = qSlicerApplication::application()->layoutManager();

  // loop through all existing threeDViews
  vtkNew<vtkThreeDViewInteractorStyle> interactorStyle;
  for (int i=0; i < layoutManager->threeDViewCount(); ++i)
    {
    qMRMLThreeDView* view = layoutManager->threeDWidget(i)->threeDView();
    // Update Interactor style
    this->SetInteractorStyle(view, interactorStyle.GetPointer());
    // Reset focal point
    view->resetFocalPoint();
    }

  // Update icon
  Q_D(qSlicerMouseModeToolBar);
  d->InteractorStyleToolButton->setIcon(QIcon(":/Icons/TrackBall.png"));
}
  • Issue : not setting the interactor per view but for all views
  • Solution : adding the switch in each 3D View Qt controller
