这篇文章将为大家详细讲解有关python+PyQT怎么实现系统桌面时钟?,小编觉得挺实用的,因此分享给大家做个参考,希望大家阅读完这篇文章后可以有所收获。
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.
