TObjectList prüfen ob Index exitstiert

[Hawkeye219]

Hallo,

wo steht, daß eine TObjectList keine Lücken zuläßt?

Delphi-Quellcode:

List := TObjectList.Create;

List.Add (TObject.Create);
List.Add (TObject.Create);
List.Add (TObject.Create);
List.Add (TObject.Create);
List.Add (TObject.Create);
Count := List.Count;  // Count=5

List[3] := NIL;
Count := List.Count;  // Count=5

List.Pack;
Count := List.Count;  // Count=4

List.Free;

Gruß Hawkeye
