CefMenuModel (CEF3 Java API Docs)

```
public interface CefMenuModel
```
Supports creation and modification of menus. See cef_menu_id_t for the command ids that have default implementations. All user-defined command ids should be between MENU_ID_USER_FIRST and MENU_ID_USER_LAST. The methods of this class can only be accessed on the browser process the UI thread.
支持创建和修改菜单。有关具有默认实现的命令ID，请参阅cef_menu_id_t。所有用户定义的命令ID都应在MENU_ID_USER_FIRST和MENU_ID_USER_LAST之间。此类的方法只能在浏览器处理UI线程上访问
