基于Linux的音乐播放器设计与实现专业：计算机科学与技术学号：学生：指导教师：摘要：作为一项与人们生活息息相关的应用，音乐播放器在人们的生活中发挥着不可替代的作用。本播放器在Linux(Debian6.0)操作系统平台下进行开发，使用Qt程序开发框架实现播放器的GUI设计，并用Phonon多媒体API实现多媒体控制，最后再用C++编程实现。本播放器实现了音乐播放器的基本功能，包括“播放”、“暂停”、“上一曲”、“下一曲”、“添加文件”、“删除文件”、“切换背景图标”、“最小化到托盘”等功能。测试表明，本播放器能够流畅地运行，并能很好地实现各项功能，并且有一定的容错能力，达到了设计预期的效果。同时，本播放器在稳定性、经济成本等方面都有不错的表现。关键词：音乐播放器；Linux；Qt；PhononTheDesignandImplementationofMusicPlayerBasedonLinuxSpecialty:StudentNumber:Student:Supervisor:Abstract:Asanapplication,whichiscloselyrelatedtothepeople'slives,musicplayerplaysanirreplaceableroleinpeople'slife.ThisMusicplayerisdevelopedunderLinux(Debian6.0)operatingsystemwiththeQtapplicationdevelopmentframeworkimplementingtheplayer'sGUIdesign.PhononmultimediaAPIsisusedformultimediacontrolandatlastcodedbyC++programminglanguage.Themusicplayerhasrealizedbasicfunctionsofordinarymusicplayer,including'Play'function,'Pause'function,'Previoustrack'function,'Nexttrack'function,'Addfiles'function,'Deletefiles'function,'Switchbackgroundicon'function,'Minimizetotray'functionandsoon.Thetestingresultsshowthattheplayercanrunsmoothlyandrealizealloffunctionsmentionedbefore.Theplayerisprovidedwithfaulttoleranceaswell.Tosumup,theplayerachievesthedesign'sexpectedresult.Atthesametime,themusicplayerhasawellperformanceinoperationalstabilityandeconomiccost.Keywords:Musicplayer;Linux;Qt;PhononPAGE\*MERGEFORMATII目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc325706897"绪论PAGEREF_Toc325706897\h1HYPERLINK\l"_Toc325706898"1系统开发平台介绍PAGEREF_Toc325706898\h2HYPERLINK\l"_Toc325706899"1.1Linux简介PAGEREF_Toc325706899\h2HYPERLINK\l"_Toc325706900"1.2Qt介绍PAGEREF_Toc325706900\h3HYPERLINK\l"_Toc325706901"1.3集成开发环境PAGEREF_Toc325706901\h3HYPERLINK\l"_Toc325706902"1.4Phonon简介PAGEREF_Toc325706902\h4HYPERLINK\l"_Toc325706903"2系统分析PAGEREF_Toc325706903\h5HYPERLINK\l"_Toc325706904"2.1播放器举例PAGEREF_Toc325706904\h5HYPERLINK\l"_Toc325706905"2.2功能需求分析PAGEREF_Toc325706905\h5HYPERLINK\l"_Toc325706906"2.2.1基本功能PAGEREF_Toc325706906\
