Protected Methods
| Name | Description | |
|---|---|---|
 | CollapseChild | Center all the objects that aren't links and make everything invisible (besides Label and Handle and Port and CollapsedObject). |

| ComputeReferencePoint | Return the point from which the relative positions of the children are calculated. |
| CopyChildren | Overridden. This override is needed to make sure the expanded position information is copied correctly when this subgraph is collapsed at the time of the copy. |
| CreateCollapsedObject | This method is called to create an object that is displayed when the node is collapsed. |
| CreateHandle | This method is called to create the "handle" representing the whole subgraph that the user can select to drag or click to collapse or expand the subgraph. |

| ExpandChild | Restore a child to its original position. |
| FinishCollapse | This method is called towards the end of the process of a Collapse call. |
| FinishExpand | This method is called at the end of the process of an Expand call. |

| OnBoundsChanged | Overridden. When collapsed, update saved bounds for expand when empty. |
| OnLayerChanged | Called when this object's layer is changed. (Inherited from Northwoods.Go.GoObject) |
