如何在一个窗体中嵌入另一个窗体

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
//Form1 父窗体

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;

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;
//Form2 子窗体

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;
