    B:pursued

    答案:A

  • 第5题:

    请判断下列代码在程序关闭时,正确的对象释放顺序

    TMybutton=class(Tbutton)

    Protected

    Destructor Destroy;override;

    End;

    …………

    destructor TMyButton.Destroy;

    Begin

    inherited;

    Application.MessageBox(PChar(Name),’Destroy’,mb_ok);

    end;

    var AButton,BButton:TMyButton;

    procedure TForm1.FormCreate(Sender:TObject);

    begin

    Abutton:=TmyButton.Create(Nil);

    With AButton do

    begin

    Parent:=form1;

    Top:=100;

    Left:=100;

    Visible:=True;

    Name:=’ABtn’;

    end;

    BButton:=TMyButton.Create(Application);

    With BButton do

    begin

    Parent:=Form1;

    Top:=100;

    Left:=200;

    Visible:=True;

    Name:=’BBtn’;

    end;

    procedure TForm1.FormDestroy(Sender:TObject);

    begin

    …………

    end;

    A.BButton.Destroy->Form1.Destroy->AButton.Destroy

    B.上述都不对,应该手工调用 Abutton.free,否则会造成AButton没有释放的

    错误

    C.Form1.Destroy->AButton.Destroy->BButton.Destroy

    D.AButton.Destroy->Form1.Destroy->BButton.Destroy
