Inherited Constructor (add a Parameter)?

[PascalDragon]

Code: Pascal  [Select][+][-]

1. MyList.Create(S));
2. TMyList.Create(S));
3.  

The first variant simply calls the constructor as a normal method.
The second is a real constructor call with compiler magic to instantiate a new instance using TMyList.NewInstance before calling the constructor.

Class helper could help too.

Code: Pascal  [Select][+][-]

1. TMemohelper= class helper for TMemo
2.    procedure addlines(S: string);
3.  end;
4.  
5.  
6. procedure TMemohelper.Addlines(S:string);
7. var list:TStringlist;
8. begin
9.   list:=TStringlist.create;
10.   list.Delimiter:=';';
11.   list.DelimitedText := S;
12.   Lines.AddStrings(list);
13.   list.free;
14. end;
