virtual void Enable()
Enable/Disable interactions.
virtual char * GetKeySym()
Set/get the key symbol for the key that was pressed.
virtual int InternalDestroyTimer(int platformTimerId)
Internal methods for creating and destroying timers that must be implemented by subclasses.
implements Win32 specific functions required by vtkRenderWindowInteractor.
virtual int InternalCreateTimer(int timerId, int timerType, unsigned long duration)
Internal methods for creating and destroying timers that must be implemented by subclasses.
virtual void SetAndroidApplication(struct android_app *app)
virtual void Initialize()
Prepare for handling events and set the Enabled flag to true.
static vtkRenderWindowInteractor * New()
platform-independent render window interaction including picking and frame rate control.

Definition: vtkIndent.h:33
virtual void ExitCallback()
These methods correspond to the Exit, User and Pick callbacks.
virtual void StartEventLoop()
Run the event loop (does not return until TerminateApp is called).

void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
static void * ClassExitMethodArg
Class variables so an exit method can be defined for this class (used to set different exit methods f...
