python+PyQT实现系统桌面时钟
用Python+PyQT写的一个系统桌面时钟，刚学习Python，写的比较简陋，但是基本的功能还可以。
功能：
①窗体在应用程序最上层，不用但是打开其他应用后看不到时间
②左键双击全屏，可以做小屏保使用，再次双击退出全屏。
③系统托盘图标，主要参考PyQt4源码目录中的PyQt4\examples\desktop\systray下的程序
④鼠标右键，将程序最小化
使用时需要heart.svg放在源代码同级目录下，[文件可在PyQt4示例代码目录下PyQt4\examples\desktop\systray\images找到
运行需要Python2.7+PyQt4.
