Detailed Description

a list of 2D actors

vtkActor2DCollection is a subclass of vtkCollection. vtkActor2DCollection maintains a collection of vtkActor2D objects that is sorted by layer number, with lower layer numbers at the start of the list. This allows the vtkActor2D objects to be rendered in the correct order.

Member Function Documentation

◆ New()

static vtkActor2DCollection * vtkActor2DCollection::New ( )

static

Destructor for the vtkActor2DCollection class.

This removes all objects from the collection.

◆ IsTypeOf()

static vtkTypeBool vtkActor2DCollection::IsTypeOf ( const char * type )

static

◆ IsA()

virtual vtkTypeBool vtkActor2DCollection::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 vtkPropCollection.

◆ SafeDownCast()

static vtkActor2DCollection * vtkActor2DCollection::SafeDownCast ( vtkObjectBase * o )

static

◆ NewInstanceInternal()

vtkActor2DCollection * vtkActor2DCollection::NewInstance ( ) const

◆ PrintSelf()

void vtkActor2DCollection::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 vtkCollection.

◆ Sort()

void vtkActor2DCollection::Sort ( )

Sorts the vtkActor2DCollection by layer number.

Smaller layer numbers are first. Layer numbers can be any integer value.

◆ AddItem()

void vtkActor2DCollection::AddItem ( vtkActor2D * a )

Add an actor to the list.

The new actor is inserted in the list according to it's layer number.

◆ IsItemPresent()

int vtkActor2DCollection::IsItemPresent ( vtkActor2D * a )

inline

Standard Collection methods.

Definition at line 112 of file vtkActor2DCollection.h.

◆ GetNextActor2D() [1/2]

vtkActor2D * vtkActor2DCollection::GetNextActor2D ( )

inline

Standard Collection methods.

Definition at line 117 of file vtkActor2DCollection.h.

◆ GetLastActor2D()

vtkActor2D * vtkActor2DCollection::GetLastActor2D ( )

inline

Standard Collection methods.

Definition at line 122 of file vtkActor2DCollection.h.

◆ GetNextItem()

vtkActor2D * vtkActor2DCollection::GetNextItem ( )

inline

Access routines that are provided for compatibility with previous version of VTK.

Please use the GetNextActor2D(), GetLastActor2D() variants where possible.

Definition at line 134 of file vtkActor2DCollection.h.

◆ GetLastItem()

vtkActor2D * vtkActor2DCollection::GetLastItem ( )

inline

Access routines that are provided for compatibility with previous version of VTK.

Please use the GetNextActor2D(), GetLastActor2D() variants where possible.

Definition at line 139 of file vtkActor2DCollection.h.

◆ RenderOverlay()

void vtkActor2DCollection::RenderOverlay ( vtkViewport * viewport )

Sort and then render the collection of 2D actors.

◆ GetNextActor2D() [2/2]

vtkActor2D * vtkActor2DCollection::GetNextActor2D ( vtkCollectionSimpleIterator & cookie )

inline

Reentrant safe way to get an object in a collection.

Just pass the same cookie back and forth.

Definition at line 90 of file vtkActor2DCollection.h.

◆ DeleteElement()

void vtkActor2DCollection::DeleteElement ( vtkCollectionElement * )

overrideprotectedvirtual

Reimplemented from vtkCollection.
