项目结构:

效果图一:

效果图二:

效果图三:

关于闹钟:



代码如下:

Alarm hongten v1.0

 使用说明:

     此文件夹中包括:
             src文件夹       存放图片和声音文件夹,使用程序的时候,请不要删除此文件夹
             alarm.jar    主要的功能程序jar包(要求安装jdk1.5或以上版本)
             ReadMe.txt     说明文档

 

  1.菜单功能说明

     文件—— >   
           上传铃声(还没实现)
           退出                     功能:退出程序
     工具—— >   
           截图工具              功能:进行截图
           更改背景        功能:更改背景
     帮助—— >   
           关于程序        功能:查看程序说明

 
  2.设置闹表

     2.1.可以在响铃时间里设置闹表时间

     2.2.还可以用快速设置,+1表示在系统时间的基础上增加一分钟,-1表示在系统时间的基础上减去一分钟                (+5,+30,-5,-30同样原理)

  3.提示铃声

     可以选择铃声类型,进行试听,试听是时候可以停止(该功能还没完善)

  4.系统托盘

     4.1.在主窗体隐藏的时候,单击左键,主窗体可以显示出来;

     4.2.在主窗体隐藏的时候,单击右键,可以进行功能选择:退出,恢复主窗体可见,截图

     4.3.在设置的闹表时间剩下30秒是时候,系统会自动提示信息(电脑右下角会弹出消息提示框)

     4.4.在设置更改背景的时候,同样会弹出提示信息(所有的提示信息会自动隐退)
