ChildCellProperty

class ipkiss3.all.ChildCellProperty

Property for assigning a Child PCell

Accepts both a PCell and a View, if a view is assigned the corresponding cell is retrieved and assigned to the property. If a ChildCellProperty is a member of a PCell class, it will automatically create corresponding ChildViewProperties in all the View classes of that Pcell class, with restrictions matching the view type.
