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
