python3GUI--打造一款时间管理工具By:PyQt5（附源码）
作者：互联网
文章目录
本次依然使用PyQt5，打造一款时间管理工具，支持两种时间格式的显示、全屏、窗口的切换以及一些个性化的设置，可以用作计时器或者屏幕保护。
一．准备工作
1.PyQt5
pyqt5是一套Python绑定Digia QT5应用的框架。它可用于Python 2和3。本教程使用Python 3。Qt库是最强大的GUI库之一。pyqt5的官方网站http://www.riverbankcomputing.co.uk/news。
pyqt5做为Python的一个模块，它有620多个类和6000个函数和方法。这是一个跨平台的工具包，它可以运行在所有主要的操作系统，包括UNIX，Windows，Mac OS。pyqt5是双重许可。开发者可以在GPL和商业许可之间进行选择。
2.Qt Designer
Qt设计师（Qt Designer）是使用Qt部件（Widgets）设计和使用图形用户界面（GUI）的工具。它允许我们以所见即所得的方式构建和定制自己的窗口（Windows）或对话框（Dialogs）并提供了不同的方法来测试它们。
二．预览
1.启动
启动软件后，就会进入软件设置界面，通过选择时间显示格式、显示模式、颜色其他设置，可以预览要展示的时间。
2.开始
点击开始后，就会进入软件主界面，软件会根据用户选择的模式和设置展示当前时间。
3.自定义样式
可以自定义日期时间显示样式
三．设计流程
1.UI设计
1.my_time.ui
此为启动界面，整体垂直布局，局部水平布局。
2.my_timer.ui
此为主界面，整体水平布局。
四．源代码

五．总结
本次使用PyQt5制作了一款时间管理工具，可以当做时钟或者屏幕保护，简约大方。本次主要练习了QTimer、QLcdNumber、信号与槽机制。最后希望大家管理好自己的时间，珍惜每分每秒，程序打包好放在了蓝奏云。思路、代码方面有什么不足欢迎各位大佬指正、批评！
