Class TChildModelCollection

Unit

PhastModelUnit

Declaration

type TChildModelCollection = class(TOrderedCollection)

Description

TOrderedCollection is a base class for collections that avoid deleting their collection items during assign whenever they can. TOrderedCollection is typically used to allow editing of the collection in a GUI. The model owns (directly or indirectly) one copy of the TOrderedCollection. Another copy will be created in the GUI in which Model will be Nil. The user will edit this latter copy in the GUI. The copy then gets assigned back to the original copy.
