If you do not specify a part name, VA Smalltalk generates a unique name based on the class name of the part.

If rubberPositioning is set to true, all children parts with no attachments on their top, bottom, left, or right, have their initial top and left positions converted to proportional attachments. If rubberPositioning is set to false, then the initial top and left positions are attached to the parent.
