我现在创建2个panle,那是不是要创建两个线程去处理
。。。。。。。。。。
rt_thread_t tTop;   //for panel 1*/
		rt_thread_t tMain;	//for panel 2

tTop = rt_thread_create("tp",
			ui_top_entry, RT_NULL,
			512, 200, 10);

tMain = rt_thread_create("wb",
			ui_main_entry, RT_NULL,
			2048, 25, 10);

if (tTop != RT_NULL) rt_thread_startup(tTop);
		if (tMain != RT_NULL) rt_thread_startup(tMain);
。。。。。。
