virtual void __fastcall Assign(System::Classes::TPersistent* Source);
Sets the strings in the list, and possibly associated objects, from a source object.
Use Assign to set the value of the TWideStrings object from another object. If Source is of type TWideStrings, the list is set to the list of the source TWideStrings object, and if associated objects are supported, any associated objects are copied from the Source as well.
