使用QML仿写了一个PC端微信的界面，具有以下功能：
1.可以显示文本、图片、音频、视频
2.显示的内容根据“发送方”自动左对齐或者右对齐
3.支持全屏查看图片
4.视频可以播放，不过好像需要安装解码器（我装的是LAV Filters）
QML copy of the use of a PC end micro channel interface, with the following functions:
1 can display text, pictures, audio, video
2 shows the content according to the sender automatic left or right aligned
3 support full screen view picture
4 video can be played, but it seems to need to install the decoder (I installed Filters LAV) (2015-11-10, QT, 99KB, 下载21次)
