Qt5.8 QMediaPlayer 音乐播放器
来源：互联网 发布：苍穹测绘软件视频教程 编辑：程序博客网 时间：2024/05/21 06:52
学了半个月的Qt 做了个音乐播放器 实现了简单的功能 播放/暂停 歌曲 下一曲 上一曲 添加歌曲 查找歌曲 删除歌曲 添加至我喜欢 右键菜单 双击事件 更换皮肤 切换播放模式 清除列表 定位歌曲等功能 在做播放器的过程中 更熟悉了QMediaPlayer类 ，和 QMediaPlaylist 类的使用 以及一些窗体如QListWidget 堆栈窗体等的使用 程序思路比较简单
先定义个QMediaPlaylist *Playlist来存储播放歌曲的列表 ，使用ListWidget 来显示播放列表 ，然后在开个数据库来存储播放l列表歌曲的所在路径，然后在定义QMediaPlayer *music 来播放歌曲，另外还有一些功能没有实现 比如歌词，多选操作等 以后再尽量完成这些功能吧 下面是程序运行结果
还可以切换至小播放器模式
因为第一次写Qt大项目 所以代码写的有点乱
下面是一些源码(仅供参考):
