我實驗了一下，父類別沒有virtual，子類別沒有override，
只要有"inherited 方法名"就等於直接拷貝該父類別方法，
如果沒有"inherited 方法名"就等於覆蓋父類別繼承下來的該方法，
那這樣不就跟父類別有virtual,子類別有override修飾字時的情況一樣了嗎??    我實驗的三個unit：    unit Unit1;    interface    uses
  Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
  StdCtrls, Buttons;    type
  TForm1 = class(TForm)
    BitBtn1: TBitBtn;
    procedure BitBtn1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;    var
  Form1: TForm1;    implementation    uses
  unit2,unit3;    {$R *.DFM}    procedure TForm1.BitBtn1Click(Sender: TObject);
begin
  test1 := Ttest1.create;
  test2 := ttest2.create;      test1.abc;
  test2.abc;
end;    end.        unit Unit2;    interface    uses
  Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
  StdCtrls, Buttons;          type
  Ttest1 = class
    procedure abc;
  end;
  
var
  test1 : ttest1;    implementation    procedure Ttest1.abc;
begin
  showmessage('test1.abc');
end;    end.        unit Unit3;    interface    uses
  Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
  StdCtrls, Buttons, unit2;    type
  Ttest2 = class(Ttest1)
    procedure abc;
  end;
  
var
  test2 : ttest2;    implementation    procedure Ttest2.abc;
begin
  inherited abc;
  showmessage('test2.abc');
end;    end.
