Signals and Slots in Depth 深入信号和槽
Note that signals can also carry any data to the slots they are connected to, even though we don't show examples of that here.
信号也可以将任何数据传送到它们所连接的插槽，尽管在这里我们没有显示这样的示例。
With signals/slots, it is much easier to control communications between objects in a flexible and maintainable manner than it is with a fragile callback style.
使用信号／插槽以灵活且可维护的方式控制对象间通信要比使用脆弱的回调风格容易得多。
This is thanks to Qt's signals and slots mechanism we covered previously.
这要借助于我们前面提过的Qt的信号与槽机制。
