窗口最小化后如何还原
直接调用 window 的 orderFront 是不好使的，其实 window 进入了 miniaturize 模式了，只要调用 deminiaturize 方法就行了:

鼠标 Hover 时指针变成小手
创建 NSTrackingArea 对象时，options 传入 NSTrackingCursorUpdate ；然后设置成想要的指针类型就好了。通过 mouseEnter 和 mouseExit 实现会有bug，有的时候鼠标进入了指针却没能改变！

[[NSCursor pointingHandCursor] set];

模拟鼠标单击
测试发现，会弹出一个辅助功能控制电脑的弹框，默认是不允许的，所以项目中并没有用这个方案。
