Interface Xj3DCADView

public interface Xj3DCADView

Wrapper interface for the internal viewpoint representation, to allow abstraction of the user interface description of viewpoints from the underlying node representation.

This class deliberately does not give access to the SAI X3DNode that represents the viewpoint.

Method Summary

void	addCADViewListener(Xj3DCADViewListener l) Add a listener for CAD-style changes.
X3DNode[]	getCADAssemblies() Get the list of layers declared in the current scene.
X3DNode[]	getCADLayers() Get the list of layers declared in the current scene.
void	highlightPart(X3DNode structureNode, X3DNode material) Highlight the given part or assembly using the given alternate appearance attributes.
void	removeCADViewListener(Xj3DCADViewListener l) Remove a listener for CAD-style changes.

Method Detail

getCADLayers

X3DNode[] getCADLayers()

Get the list of layers declared in the current scene. If the scene does not contain any layers, it will return null.

getCADAssemblies

X3DNode[] getCADAssemblies()

Get the list of layers declared in the current scene. If the scene does not contain any layers, it will return null.

highlightPart

void highlightPart(X3DNode structureNode,
                   X3DNode material)

Highlight the given part or assembly using the given alternate appearance attributes. This will temporarily override the appearance on all sub-children until one of the following conditions are met:

• The world is replaced
• The parent scene graph containing this structure node is removed
• Another part or structure is requested to be highlighted
• This same node is requested, but with a null material parameter

Once highlighting has stopped, the ordinary material values are returned.

Parameters:

structureNode - A X3DProductStructureNode to be highlighted (or PROTO wrapper of one)

material - A X3DmaterialNode to use as the highlight colour, or null to clear the current highlighted object

addCADViewListener

void addCADViewListener(Xj3DCADViewListener l)

Add a listener for CAD-style changes. Adding the same listener instance more than once will be silently ignored. Null values are ignored.

Parameters:

l - The listener instance to add

removeCADViewListener

void removeCADViewListener(Xj3DCADViewListener l)

Remove a listener for CAD-style changes. If this listener is not currently registered, the request will be silently ignored.

Parameters:

l - The listener instance to remove
