本例子为在Form1的Panel中显示Form2窗体，请注意例子中的reintroduce关键字
//Form2 子窗体 uses unit2; procedure TForm1.FormCreate(Sender: TObject); begin form2 := TForm2.Create(Panel,self); form2.BorderStyle := bsNone; form2.WindowState := wsMaximized; form2.Parent := Panel; form2.Show; end; //Form1 父窗体 uses Unit1; private FOwnerForm : TForm; end; constructor Create(AOwner: TComponent; OwnerForm: TForm ); reintroduce;//响应父窗体事件的关键 constructor TForm2.Create(AOwner: TComponent; OwnerForm: TForm); begin inherited Create(Aowner); FOwnerForm := OwnerForm; end; //事件触发（在FORM2中来响应FORM1的事件） procedure TForm2.Button1Click(Sender: TObject); begin if Self.FOwnerForm.ClassType = TForm1 then begin ShowMessage('按下我了！'); end; end;
