今天看了一点点QWebView，于是有了把web.kugou.com做成客户端的想法。折腾了一天，这是最终效果：
因为默认加载蓝色界面，所以界面适配默认蓝色。
Qt版本为5.1.1，下面是代码：

利用QLabel（tittleBar）控件，屏蔽了webkugou的上侧如下图的位置。屏蔽系统框架，重写鼠标事件，实现窗口拖动。同时利用背景渐变，使其很自然过渡到播放界面。
使用了Qt的webkitwidgets，很方便地加载网页内容。调试的时候需要将NPSWF32_11_8_800_168.dll（或者其他版本的NPSWF32.dll）拷贝至Release的pugins目录下，否则flash无法加载。需要使用Release调试，不知什么原因Debug调试时，在加载flash时会崩溃。
