Class TContour2DNode

Unit

X3DNodes

Declaration

type TContour2DNode = class(TAbstractNode)

Description

Groups a set of curve segments for a composite contour, for X3D.

X3D cannot share implementation with VRML 2.0 version (TContour2DNode_2), since for VRML 2.0 this is a valid geometry node (TAbstractGeometryNode descendant).

Hierarchy

Overview

Methods

	function DirectEnumerateActive(Func: TEnumerateChildrenFunction): Pointer; override;
	class function ForVRMLVersion(const Version: TX3DVersion): boolean; override;
	procedure CreateNode; override;
	class function ClassX3DType: String; override;
	procedure SetChildren(const Value: array of TX3DNode);

Properties

	property EventAddChildren: TMFNodeEvent read FEventAddChildren;

Description

Methods

	function DirectEnumerateActive(Func: TEnumerateChildrenFunction): Pointer; override;

	class function ForVRMLVersion(const Version: TX3DVersion): boolean; override;

	procedure CreateNode; override;
Create node fields and events.

	class function ClassX3DType: String; override;

	procedure SetChildren(const Value: array of TX3DNode);

Properties

	property EventAddChildren: TMFNodeEvent read FEventAddChildren;

	property EventRemoveChildren: TMFNodeEvent read FEventRemoveChildren;

	property FdChildren: TMFNode read FFdChildren;
Internal wrapper for property Children. This wrapper API may change, we advise to access simpler Children instead, if it is defined (TODO: for now, some field types do not have a simpler counterpart).
