/**
|

* @brief The DisplayManager class
|
||
* @note 1、对QScreen信息的获取和监听进行了封装，不应该在此程序的其他处再出现类似的代码，而是从当前实例中进行提供
|
||
* @note 2、对显示相关数据的读写尽可能通过Qt库进行，而不是通过一些DBus服务，
|
||
* @note 目的一是为了解耦
|
||
* @note 二是DBus服务的稳定性较低，有部分问题存在
|
||
* @note 三是DBus服务(特指Display相关)刚开始的目的是为了做一些架构和特殊机器的兼容适配工作，因为qt适配开展较慢，所以才有了DBus服务的存在，目前qt已足够稳定，我们不应该再大量使用后端提供的Display服务
