Abstract
A graphical object in an object-oriented environment is comprised of a plurality of child graphical objects. The parent graphical object and each of the child graphical objects have a property corresponding to the orientation of a representation of the respective object. A connection tree is formed from the parent graphical object which has the initial values of each property of the child graphical objects. During operation, the value of the property of the graphical object may be altered corresponding to a change in the position of the object's graphical representation. The altered value is broadcast through the connection tree to allow recalculation of each child object's property based upon its initial value so that the parent object and its child objects can be graphically displayed based on the changed position.
