在网上找了一个别人的旧版本的播放器~自己更改了一天，终于可运行了，希望分享下同共学习；
不过出了少少问题：希望有经验的一起指导下：
运行环境：qt creator +windows
1、原计划是可支持视频播放的，现在只能加载间频（mp3），一加载视频就卡死
2.、自定义的进度条不起作用，不知为什么百分比槽连接不成功
connect(wmp, SIGNAL(PositionChange(double, double)),this, SLOT(Slot_onPositionChange(double, double)));
3、我用的是QAxWidget控件，这个是不是只支持windows的呢？或者还有没其实更好的？
