各位大佬，代码如下，没有任何显示内容，为啥？？
	struct rtgui_app *myapp;
	struct rtgui_win *mywin;
	struct rtgui_rect myrect;
	struct rtgui_box *mybox;
	rtgui_rect_t mymain_win_rect;
	
	rtgui_label_t  *mylabel_ready_state;

myapp=rtgui_app_create("MyApp");
	RT_ASSERT(myapp!=RT_NULL);
	
	rtgui_graphic_driver_get_rect(rtgui_graphic_driver_get_default(),&myrect);
	
	//win=rtgui_win_create(RT_NULL,"MainWin",&rect,RTGUI_WIN_STYLE_DEFAULT);
	mywin=rtgui_mainwin_create(RT_NULL,"MainWin",RTGUI_WIN_STYLE_DEFAULT);
	if(mywin == RT_NULL)
	{
		rt_kprintf("create windown failed<br>");
		rtgui_app_destroy(myapp);
		return;
	}

mybox = rtgui_box_create(RTGUI_VERTICAL, 5);	
	rtgui_container_set_box(RTGUI_CONTAINER(mywin), mybox);
	rtgui_container_layout(RTGUI_CONTAINER(mywin));

rtgui_widget_get_rect(RTGUI_WIDGET(mywin),&mymain_win_rect);
	
	
	rt_kprintf("x1:%d y1:%d x2:%d y2:%d<br>",myrect.x1,myrect.y1,myrect.x2,myrect.y2);
	mylabel_ready_state = rtgui_label_create("READY");
	RTGUI_WIDGET_BACKGROUND(RTGUI_WIDGET(mylabel_ready_state)) = black;
	RTGUI_WIDGET_FOREGROUND(RTGUI_WIDGET(mylabel_ready_state)) = green;
	RTGUI_WIDGET_TEXTALIGN(mylabel_ready_state) = RTGUI_ALIGN_CENTER;
	mylabel_ready_state->visible = RT_TRUE;
	myrect = (rtgui_rect_t){0,100,100,200};
	rtgui_rect_moveto_align(&mymain_win_rect,&myrect,RTGUI_ALIGN_CENTER_HORIZONTAL|RTGUI_ALIGN_TOP);
	rtgui_label_set_rect(mylabel_ready_state,&myrect);

rtgui_container_add_child(RTGUI_CONTAINER(mywin),RTGUI_WIDGET(mylabel_ready_state));

RTGUI_WIDGET_BACKGROUND(RTGUI_WIDGET(mywin)) = red;
	
	
	rtgui_win_show(mywin,RT_FALSE);
	rtgui_app_run(myapp);
