Gets or sets if this instance makes use of the IZOrderSupport found in the graph's lookup.

If true, model items placed in the same ICanvasObjectGroup are sorted by their z-order provided by the found IZOrderSupport.

Note that the following methods may only be called if this property is set to true:

• synchronizeZOrders
• normalizeZOrders
• raise
• raiseSelection
• lower
• lowerSelection
• toFront
• selectionToFront
• toBack
• selectionToBack

After enabling z-order support you should either call synchronizeZOrders to adjust the visual z-orders to the values provided by the IZOrderSupport or normalizeZOrders to adjust the values in IZOrderSupport to reflect the current visual z-orders.

The default value is false.

Retrieves the Canvas Object group to use for the given node.

This implementation is called by the default instance that is created by createNodeCanvasGroupProvider

Parameters

See also

Retrieves all canvas objects that have been registered for the given item or null.

Parameters

Retrieves the Canvas Object group to use for the given edge.

This implementation is called by the default instance that is assigned to createEdgeCanvasGroupProvider()

Parameters

See also

Retrieves the canvas object group the given edge label shall be installed in depending on the set labelLayerPolicy.

Parameters

Retrieves the main canvas object that has been registered for the given item or null.

This implementation treats the first element in the array of canvas objects installed into the canvas for the item as the main object.

Parameters

Retrieves the main render canvas object that has been registered for the given item or null.

The main render canvas object of an IModelItem represents the root of the subtree of the canvas object tree that contains the main canvas objects as well of the model item as of all model items whose rendering depends on this item.

This might be the main canvas object of the item itself (if no other item rendering depends on it) or an ICanvasObjectGroup (e.g. for a group nodes whose children depends on its rendering).

Parameters

Retrieves the corresponding IModelItem for the given canvas object.

Parameters

Retrieves the canvas object group the given node label shall be installed in depending on the set labelLayerPolicy.

Parameters

Retrieves the canvas object group the given port shall be installed in depending on the set portLayerPolicy.

Parameters

Iterates hits on the canvas at a given world coordinate position. Only if the given filter function returns true for a hit ICanvasObject, it is included in the iterator.

The instance returned will enumerate hits in the order so that the topmost visual element will be reported first.

Parameters

Moves the main render canvas object of the passed IModelItem one step closer to the beginning of the group rendering list, so that it will be painted behind of its current predecessor. This is done by setting appropriate z-orders via the IZOrderSupport of the set graph.

Note that this method may only be called if the useZOrderSupport property is true, otherwise an IllegalOperationError is thrown.

Parameters

Moves the main render canvas objects of all selected model items one step closer to the beginning of the group rendering list, so that they will be painted behind their current unselected predecessors.

This is done by setting appropriate z-orders via the IZOrderSupport of the set graph.

Note that this method may only be called if the useZOrderSupport property is true, otherwise an IllegalOperationError is thrown.

Parameters

Uses the visual z-order of the model items to set normalized z-order indices using the IZOrderSupport of the set graph.

More precisely the main render canvas objects of the IModelItems in each ICanvasObjectGroups are numbered increasingly from back to front and starting by 0. A canvas object's number ist then set as the model item's z-order.

Note that this method may only be called if the useZOrderSupport property is true, otherwise an IllegalOperationError is thrown.

Moves the main render canvas object of the passed IModelItem one step closer to the end of the group rendering list, so that it will be painted on top of its current successor. This is done by setting appropriate z-orders via the IZOrderSupport of the set graph.

Note that this method may only be called if the useZOrderSupport property is true, otherwise an IllegalOperationError is thrown.

Parameters

Moves the main render canvas objects of all selected model items one step closer to the end of the group rendering list, so that they will be painted on top of their current unselected successors.

This is done by setting appropriate z-orders via the IZOrderSupport of the set graph.

Note that this method may only be called if the useZOrderSupport property is true, otherwise an IllegalOperationError is thrown.

Parameters

Moves the main render canvas objects of all selected model items to the beginning of the group rendering list, so that they will be painted behind all unselected items in the same group.

This is done by setting appropriate z-orders via the IZOrderSupport of the set graph.

Note that this method may only be called if the useZOrderSupport property is true, otherwise an IllegalOperationError is thrown.

Parameters

Moves the main render canvas objects of all selected model items to the end of the group rendering list, so that they will be painted in front of all unselected items in the same group.

This is done by setting appropriate z-orders via the IZOrderSupport of the set graph.

Note that this method may only be called if the useZOrderSupport property is true, otherwise an IllegalOperationError is thrown.

Parameters

Synchronizes the visual z-order of the model items with their z-order index provided by the IZOrderSupport of the set graph.

More precisely the main render canvas objects of the IModelItems in each ICanvasObjectGroups are sorted increasingly (from back to front) by their mapped index.

Note that this method may only be called if the useZOrderSupport property is true, otherwise an IllegalOperationError is thrown.

Moves the main render canvas object of the passed IModelItem to the beginning of the group rendering list, so that it will be painted behind all other items in the same group. This is done by setting appropriate z-orders via the IZOrderSupport of the set graph.

Note that this method may only be called if the useZOrderSupport property is true, otherwise an IllegalOperationError is thrown.

Parameters
