RTGUI APP CREAT 疑问 (fixed)

RTT版本 1.1.0RC 请问 app->mq = rt_mq_create("rtgui", sizeof(union rtgui_event_generic), 32, RT_IPC_FLAG_FIFO);里消息队列名字都是"RTGUI"，那如果创建了多个APP，那消息队列OBJECT 名字不都是一样？如果用rt_object_t rt_object_find(const char *name, rt_uint8_t type) 函数查找的话是否有点问题？当然这不影响正常使用，应该没有人会用rt_object_find查找一个对象吧。

```struct rtgui_app* rtgui_app_create(
        rt_thread_t tid,
        const char *title)
{
	rt_thread_t srv_tid;
	struct rtgui_app *app;
	struct rtgui_event_application event;

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

/* create application */
	app = RTGUI_APP(rtgui_object_create(RTGUI_APP_TYPE));
	if (app == RT_NULL)
		return RT_NULL;

/* one thread only can create one rtgui application */
	RT_ASSERT(tid->user_data == 0);
	app->tid = tid;
	/* set user thread */
	tid->user_data = (rt_uint32_t)app;

app->mq = rt_mq_create("rtgui", sizeof(union rtgui_event_generic), 32, RT_IPC_FLAG_FIFO);
	if (app->mq == RT_NULL)
	{
		rt_kprintf("create msgq failed.
");
		goto __mq_err;
	}

/* set application title */
	app->name = (unsigned char*)rt_strdup((char*)title);
	if (app->name == RT_NULL)
		goto __err;

/* send a message to notify rtgui server */
	srv_tid = rtgui_get_server();
	if (srv_tid == RT_NULL)
	{
		rt_kprintf("gui server is not running.
");
		goto __err;
	}

/* create the rtgui server application */
	if (srv_tid == rt_thread_self())
		return app;

RTGUI_EVENT_APP_CREATE_INIT(&event);
	event.app = app;

/* notify rtgui server to one application has been created */
	if (rtgui_send_sync(srv_tid, RTGUI_EVENT(&event), sizeof(event)) == RT_EOK)
	{
		return app;
	}

__err:
__mq_err:
	rtgui_object_destroy(RTGUI_OBJECT(app));
	tid->user_data = 0;
	return RT_NULL;
}```
