* 1. 将所有通道切换处理全部集中到一个类。
* 2. 通用整数倍数布局切换函数，可方便拓展到100、255通道等。
* 3. 通用异形布局切换函数，可以参考进行自定义异形布局。
* 4. 通道布局切换发出信号通知。
* 5. 可控每种布局切换菜单是否启用。
* 6. 支持自定义子菜单布局内容。
* 7. 支持设置对应的菜单标识比如默认的通道字样改成设备。

/**
* 监控画面切换控件 作者:feiyangqingyun(QQ:517216493) 2021-11-08
* 1. 将所有通道切换处理全部集中到一个类。
* 2. 通用整数倍数布局切换函数，可方便拓展到100、255通道等。
* 3. 通用异形布局切换函数，可以参考进行自定义异形布局。
* 4. 通道布局切换发出信号通知。
* 5. 可控每种布局切换菜单是否启用。
* 6. 支持自定义子菜单布局内容。
* 7. 支持设置对应的菜单标识比如默认的通道字样改成设备。
