music-player's Issues

Build errors: non-existing headers; sign_up_win.cpp: error: 'void QAbstractButton::clicked(bool)' is protected within this context; etc.

Apparently it uses Qt5-only headers with Qt4 build. These do not exist, for example:

#include <QMediaPlayer>      // 实现多媒体的 应用
#include <QMediaPlaylist>

Then, the build fails on:

请问一下就是这个项目，没有附带数据库么，数据库需要自己去设计么？
