python+PyQT实现系统桌面时钟

2021-04-20 00:43智元元 Python

这篇文章主要为大家详细介绍了python+PyQT实现系统桌面时钟,文中示例代码介绍的非常详细,具有一定的参考价值,感兴趣的小伙伴们可以参考一下

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.
