铃音定时播放系统.docx

铃音定时播放系统程序功能程序的主要功能是定时播放音乐。为了符合学校的需求，本程序设定了方案为主的方式，进行配置。在一个方案可以随意建立256条以内的项目，每条项目有描述，时间，音乐地址三项描述，可以在24小时的时间内自动播放。本程序还内置了4种方案，进行修改后可以符合学校不同季节不同的作息时间安排。程序流程图1 保存当前方案2 保存内置的方案3 保存音乐播放数据1. 循环更新时间2. 按时间定时播放音乐3. 显示下一项目1. 添加项目2. 删除项目3. 按时间进行项目排序程序代码MusicF.pro#-# Project created by QtCreator 2015-08-07T08:13:53#-QT += core guigreaterThan(QT_MAJOR_VERSION, 4): QT += widgets QT += multimediawidgetsTARGET = MusicFTEMPLATE = appSOURCES += main.cpp mainwindow.cpp modelmusic.cpp adddlg.cpp datadelegate.cppHEADERS += mainwindow.h modelmusic.h adddlg.h datadelegate.hmain.cpp/主要功能：/显示程序打开前的画面/创建主窗口/#include mainwindow.h#include #include int main(int argc, char *argv) QApplication a(argc, argv);
