在多子菜单中切换状态 [英] switch statment in multi sub menu
问题描述
hi
我在做液晶显示器.我想在此LCD中制作编辑菜单.
在此LCD中，我们可以同时显示四行.
但我的确切问题是我们内部和内部都有许多子菜单.
我们如何在LCD中实现它.
这是我的计划.
主菜单
>>控件
>> TS IP
IP地址
网关
子网掩码
>>管理IP
IP地址
网关
子网掩码
>>输入
>>视频
>>来源
>> SDI
>> HDMI
>>组件
>>宽度
>>高度
>>视频格式
>>帧
>>音频
>>来源
>>模拟
>>嵌入式
>> AES-EBU HDMI
>>样品
>>服务
>>服务名称
>>服务提供商
>>服务编号
>> PMT PID
....
>>输出
>>视频
>>压缩
>>编码类型
>>比特率
>>个人资料
>>等级
>>音频
>> TYPE
>> ASI
>>多播
>> UDP/RTP
>>目标IP
>>港口
>> UNICAST
>> UDP/RTP
>>目标IP
>>港口
我们如何实现它.

推荐答案
我看不出问题是什么.这是液晶显示屏，所以甚至可以运行Windows吗?如果不是，则C ++不支持菜单，因此答案必须取决于您将使用的特定UI库.或者，您是在问我们如何容纳16条线(只有4条线)?这又取决于您正在编程的内容，可以滚动吗?如果没有，您就不能，您需要重新设计菜单.对我来说似乎很明显.
I don''t see what the question is. This is an LCD, so is it even running Windows ? If not, C++ has NO menu support, so the answer has to rely on the specific UI library you will use. Or are you asking us how to fit 16 lines where you can only have 4 ? That depends again on what you''re programming, can you have scrolling ? If not, you can''t, you need to redesign your menus. Seems obvious to me.
在星期四晚上，这是一个不错的练习:
Thats a nice exercise for a thuresday evening:
#pragma once
#include <stdio.h>
#include <tchar.h>
enum{ LCD_LINES=4, };
typedef enum
{
APP_QUIT,
MAIN,
Controls,
MANAGEMENT_IP,
Input,
AUDIO,
Service,
Output,
// Controls,

} MENUITEMS;
#define ITEM
(S)__ T(#S)， const TCHAR * __ menuitems [] = { ITEM
(S) __T( #S ), const TCHAR* __menuitems[] = { ITEM
