Member Function Documentation

New()

static vtkSDL2RenderWindowInteractor * vtkSDL2RenderWindowInteractor::New ( )

static

Construct object so that light follows camera motion.

IsTypeOf()

static vtkTypeBool vtkSDL2RenderWindowInteractor::IsTypeOf ( const char *  type )

static

IsA()

virtual vtkTypeBool vtkSDL2RenderWindowInteractor::IsA ( const char *  name )

virtual

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.

Reimplemented from vtkRenderWindowInteractor.

SafeDownCast()

static vtkSDL2RenderWindowInteractor * vtkSDL2RenderWindowInteractor::SafeDownCast ( vtkObjectBase *  o )

static

NewInstanceInternal()

virtual vtkObjectBase * vtkSDL2RenderWindowInteractor::NewInstanceInternal ( ) const

protectedvirtual

Reimplemented from vtkRenderWindowInteractor.

NewInstance()

vtkSDL2RenderWindowInteractor * vtkSDL2RenderWindowInteractor::NewInstance

const

PrintSelf()

void vtkSDL2RenderWindowInteractor::PrintSelf ( ostream &  os, vtkIndent  indent  )

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkRenderWindowInteractor.

Initialize()

virtual void vtkSDL2RenderWindowInteractor::Initialize ( )

overridevirtual

Initialize the event handler.

Reimplemented from vtkRenderWindowInteractor.

ProcessEvents()

void vtkSDL2RenderWindowInteractor::ProcessEvents ( )

overridevirtual

Run the event loop and return.

This is provided so that you can implement your own event loop but yet use the vtk event handling as well.

Reimplemented from vtkRenderWindowInteractor.

TerminateApp()

void vtkSDL2RenderWindowInteractor::TerminateApp ( void  )

overridevirtual

SDL2 specific application terminate, calls ClassExitMethod then calls PostQuitMessage(0) to terminate the application.

An application can Specify ExitMethod for alternative behavior (i.e. suppression of keyboard exit)

Reimplemented from vtkRenderWindowInteractor.

ExitCallback()

void vtkSDL2RenderWindowInteractor::ExitCallback ( )

overridevirtual

These methods correspond to the Exit, User and Pick callbacks.

They allow for the Style to invoke them.

Reimplemented from vtkRenderWindowInteractor.

AddEventHandler()

void vtkSDL2RenderWindowInteractor::AddEventHandler

(

)

ProcessEvent()

bool vtkSDL2RenderWindowInteractor::ProcessEvent ( void *  event )

protected

InternalCreateTimer()

int vtkSDL2RenderWindowInteractor::InternalCreateTimer ( int  timerId, int  timerType, unsigned long  duration  )

overrideprotectedvirtual

SDL2-specific internal timer methods.

See the superclass for detailed documentation.

Reimplemented from vtkRenderWindowInteractor.

InternalDestroyTimer()

int vtkSDL2RenderWindowInteractor::InternalDestroyTimer ( int  platformTimerId )

overrideprotectedvirtual

SDL2-specific internal timer methods.

See the superclass for detailed documentation.

Reimplemented from vtkRenderWindowInteractor.

StartEventLoop()

void vtkSDL2RenderWindowInteractor::StartEventLoop ( )

overrideprotectedvirtual

This will start up the event loop and never return.

If you call this method it will loop processing events until the application is exited.

Reimplemented from vtkRenderWindowInteractor.
