python3GUI--打造一款时间管理工具By:PyQt5(附源码)

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

python3GUI--打造一款时间管理工具By:PyQt5(附源码)
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
python3GUI--打造一款时间管理工具By:PyQt5(附源码)
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!
