i feel the need to comment on this :-)

unless i misunderstand what you're saying, that's not quite right..
if i do:
constructor TmyPanel.Create(AOwner: TComponent);
begin
inherited;
FmyButton:=TButton.Create(self);
then you dont need to override the destructor. the TComponent.Destroy
override takes care of destroying anything that you own
(i.e. .create(self));
but if you do:
constructor TmyPanel.Create(AOwner: TComponent);
begin
inherited;
FmyList:=TStringList.Create;
then you will need a:
destructor TComponent.Destroy;
begin
FmyList.Free;
inherited;
else you will get a memory leak.
hope that clears things up a bit :-)
