Description

Methods

Protected function DefaultContainerFieldInContext(const Version: TX3DVersion; const ParentNode: TX3DNode): String; override;

This item has no description. Showing description inherited from TX3DNode.DefaultContainerFieldInContext.

Use this instead of DefaultContainerField to account that containerField may change depending on X3D version (like containerField of metadata nodes, changed between X3D 3 and 4) or parent node (like containerField of HAnimMotion). ParentNode may be Nil when it is at root.

Public procedure CreateNode; override;

Create node fields and events.

Public class function ClassX3DType: String; override;

This item has no description. Showing description inherited from TX3DNode.ClassX3DType.

Node type name in VRML/X3D, for this class. Normal VRML/X3D node classes should override this to return something non-empty, and then X3DType automatically will return the same value.

Empty for classes that don't have a hardcoded VRML/X3D node name, like a special TX3DUnknownNode. Such special classes should override then X3DType to return actual non-empty name there.

You usually should call X3DType. The only use of this method is that it works on classes (it's "class function"), without needing at actual instance.

Properties

Public property FdName: TSFString read FFdName;

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

Public property NameField: String read GetNameField write SetNameField;

This item has no description.

Public property FdReference: TSFString read FFdReference;

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

Public property Reference: String read GetReference write SetReference;

This item has no description.
