Member Function Documentation

New()

static vtkOpenGLTextActor * vtkOpenGLTextActor::New ( )

static

IsTypeOf()

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

static

IsA()

virtual vtkTypeBool vtkOpenGLTextActor::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 vtkTextActor.

SafeDownCast()

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

static

NewInstanceInternal()

virtual vtkObjectBase * vtkOpenGLTextActor::NewInstanceInternal ( ) const

protectedvirtual

Reimplemented from vtkTextActor.

NewInstance()

vtkOpenGLTextActor * vtkOpenGLTextActor::NewInstance

const

PrintSelf()

void vtkOpenGLTextActor::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 vtkActor2D.

RenderOverlay()

int vtkOpenGLTextActor::RenderOverlay ( vtkViewport *  viewport )

overridevirtual

Support the standard render methods.

Reimplemented from vtkActor2D.

RenderGL2PS()

int vtkOpenGLTextActor::RenderGL2PS ( vtkViewport *  viewport, vtkOpenGLGL2PSHelper *  gl2ps  )

protected
