SoActionSetUpState Method |
Creates state if it is NULL or it is no longer valid because new elements have been enabled since it was created.
Extender API: this api is available to programmers who wish to extend the toolkit. We strongly suggest to use it only in the cases described in the Toolmaker guide such as creating a new class inherited from SoShape. See Open Inventor Toolmaker.
Namespace: OIV.Inventor.Actions
Automatically called by the OIV.Inventor.Actions.SoAction.Apply(OIV.Inventor.Nodes.SoNode) methods, but can be useful for application to get a non-null state pointer to "pre-load" certain elements.
