vtkSliderWidget: Forbid Key Press To Turn On/Off It

You can use the key ‘i’ to enable or disable the vtkSliderWidget object defaultly. Here is a post about how to use vtkSliderWidget to control other model, Control The Size Of Model By VtkSliderWidget.

But we don’t want the shortcut key to influence the program UI sometimes. So let’s forbid it.

#include <iostream>
#include <vtkSmartPointer.h>
#include <vtkSphereSource.h>
#include <vtkActor.h>
#include <vtkConeSource.h>
#include <vtkRenderer.h>
#include <vtkRenderWindow.h>
#include <vtkPolyDataMapper.h>
#include <vtkRenderWindowInteractor.h>
#include <vtkSliderWidget.h>
#include <vtkSliderRepresentation.h>
#include <vtkSliderRepresentation3D.h>
#include <vtkWidgetEventTranslator.h>
#include <vtkTransform.h>
#include <vtkWidgetEvent.h>

//...
    vtkSmartPointer<vtkSliderWidget> sliderWidget =
        vtkSmartPointer<vtkSliderWidget>::New();

//...
    sliderWidget->KeyPressActivationOff();
