呃， 你们搞错了、不是这样的， 我碰到的问题是，当我Model第二个Windows的时候，发现底层的控件会无视第二个Windows的区域继续刷新，导致第二个windows显示错误。

此外 ，关于你们的Model,在老的GUI，我是采用另外一种方法解决的、
if (RTGUI_IS_WORKBENCH(parent_widget))
			{
				rtgui_workbench_t* workbench;
				workbench = RTGUI_WORKBENCH(win->parent_toplevel);
				workbench->flag |= RTGUI_WORKBENCH_FLAG_MODAL_MODE;
				workbench->modal_widget = RTGUI_WIDGET(win);

rtgui_workbench_event_loop(workbench);
				result = workbench->modal_code;
				workbench->flag &= ~RTGUI_WORKBENCH_FLAG_MODAL_MODE;
				workbench->modal_widget = RT_NULL;
			}
			else if (RTGUI_IS_WIN(parent_widget))
			{
				rtgui_win_t* parent_win;
				parent_win = RTGUI_WIN(win->parent_toplevel);
				parent_win->style |= RTGUI_WIN_STYLE_UNDER_MODAL;
				parent_win->modal_widget = RTGUI_WIDGET(win);
                //parent_win->parent_toplevel =  RTGUI_TOPLEVEL(win);

//rtgui_widget_update_clip(RTGUI_WIDGET(win));
				rtgui_win_event_loop(parent_win);
				result = parent_win->modal_code;
				parent_win->style &= ~RTGUI_WIN_STYLE_UNDER_MODAL;
				parent_win->modal_widget = RT_NULL;
			}
事先声明，我这样改是因为我的第二个窗口是在Windows的控件上建立的，它的Parent是第一个Windows，所以这样改之后。

void rtgui_win_event_loop(rtgui_win_t* wnd)
{
	rt_err_t result;
	rtgui_thread_t* tid;
	struct rtgui_event* event;
    rtgui_widget_t * widget;

tid = rtgui_thread_self();
	RT_ASSERT(tid != RT_NULL);

widget = wnd->modal_widget;
	/* point to event buffer */
	event = (struct rtgui_event*)tid->event_buffer;

if (wnd->style & RTGUI_WIN_STYLE_UNDER_MODAL)
	{
		while (wnd->style & RTGUI_WIN_STYLE_UNDER_MODAL)
		{
			if (tid->on_idle != RT_NULL)
			{
				result = rtgui_thread_recv_nosuspend(event, RTGUI_EVENT_BUFFER_SIZE);
				if (result == RT_EOK)
				{
					/* perform event handler */
                    //自己添加的， 为的事将事件直接传递给上一层控件
                    if ((widget != RT_NULL) && (widget->event_handler != RT_NULL))
                    {
                        widget->event_handler(widget, event);
                    }					//RTGUI_WIDGET(wnd)->event_handler(RTGUI_WIDGET(wnd), event);
				}
				else if (result == -RT_ETIMEOUT)
				{
					tid->on_idle(RTGUI_WIDGET(wnd), RT_NULL);
				}
			}
			else
			{
				result = rtgui_thread_recv(event, RTGUI_EVENT_BUFFER_SIZE);
				if (result == RT_EOK)
				{
					/* perform event handler */
                    //自己添加的， 为的事将事件直接传递给上一层控件
                    if ((widget != RT_NULL) && (widget->event_handler != RT_NULL))
                    {
                        widget->event_handler(widget, event);
                    }
					//RTGUI_WIDGET(wnd)->event_handler(RTGUI_WIDGET(wnd), event);
				}
			}
		}
	}
	else
	{
		while (!(wnd->style & RTGUI_WIN_STYLE_CLOSED))
		{
			if (tid->on_idle != RT_NULL)
			{
				result = rtgui_thread_recv_nosuspend(event, RTGUI_EVENT_BUFFER_SIZE);
				if (result == RT_EOK)
				{
					/* perform event handler */
					RTGUI_WIDGET(wnd)->event_handler(RTGUI_WIDGET(wnd), event);
				}
				else if (result == -RT_ETIMEOUT)
				{
					tid->on_idle(RTGUI_WIDGET(wnd), RT_NULL);
				}
			}
			else
			{
				result = rtgui_thread_recv(event, RTGUI_EVENT_BUFFER_SIZE);
				if (result == RT_EOK)
				{
					/* perform event handler */
					RTGUI_WIDGET(wnd)->event_handler(RTGUI_WIDGET(wnd), event);
				}
			}
		}
	}

/* destroy window */
	//rtgui_widget_destroy(RTGUI_WIDGET(wnd));
}

这样的话，就能实现Model显示下，只要上当前Windows基础上创建ModelWindows， 第二个Windows都不会出现把前一个Window退出的现象，因为它有个先后顺序，事件只会传递给最上层Windows，当前Windows退出后会自动转到前一个Windows继续运行。
