MonoOn Direction: MonoOff Specifies the direction in which the node is to be attached to the ContextNode. The values this variable can take are as follows: PREV : Attach node as a previous sibling of the context node NEXT : Attach node as a next sibling of the context node FIRSTCHILD: Attach node as the first child of the context node LASTCHILD : Attach node as a last child of the context node BoundingRect: Bounding rectangle The remaining inputs specify the status of the node: Locked: Is node locked ? Mangled: Is node mangled ? Marked: Is node marked ? Selected: Is node selected ? Purpose: This constructor initialises the nodes flags and links it to ContextNode in the direction specified by Direction. All neccesary tree links are updated. Note: SetUpShape() must be called before the NodeRegularShape is in a state in which it can be used.
