Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

## ◆ TerminateApp()

void QVTKInteractor::TerminateApp | ( |  | ) |
| overridevirtual

Overloaded terminate app, which does nothing in Qt.

Use qApp->exit() instead.

Reimplemented from vtkRenderWindowInteractor.

## ◆ Start()

void QVTKInteractor::Start | ( |  | ) |
| overridevirtual

Overloaded start method does nothing.

Use qApp->exec() instead.

Reimplemented from vtkRenderWindowInteractor.

## ◆ Initialize()

void QVTKInteractor::Initialize | ( |  | ) |
| overridevirtual

Prepare for handling events and set the Enabled flag to true.

This will be called automatically by Start() if the interactor is not initialized, but it can be called manually if you need to perform any operations between initialization and the start of the event loop.

Reimplemented from vtkRenderWindowInteractor.

## ◆ StartListening()

virtual void QVTKInteractor::StartListening | ( |  | ) |
| virtual

Start listening events on 3DConnexion device.

## ◆ StopListening()

virtual void QVTKInteractor::StopListening | ( |  | ) |
| virtual

Stop listening events on 3DConnexion device.

timer event slot

## ◆ InternalCreateTimer()

int QVTKInteractor::InternalCreateTimer | ( | int | timerId,
|  | int | timerType,
|  | unsigned long | duration
| ) |  |
| overrideprotectedvirtual

Internal methods for creating and destroying timers that must be implemented by subclasses.

InternalCreateTimer() returns a platform-specific timerId and InternalDestroyTimer() returns non-zero value on success.

Reimplemented from vtkRenderWindowInteractor.

## ◆ InternalDestroyTimer()

int QVTKInteractor::InternalDestroyTimer | ( | int | platformTimerId | ) |
| overrideprotectedvirtual

Reimplemented from vtkRenderWindowInteractor.
