本次使用PyQt5制作一款历史上的今天查看器,支持查看任一日期的历史事件,包括大事记、逝世事记、出生事记,简单又小巧,开始吧~

请确保已经安装了Python3.X,安装以下第三方库。

  1. PyQt5 用于QT代码的撰写
pip install PyQt5

2.PyQt5-tools 使用其中的QT设计师,进行QT界面设计

pip install PyQt5-tools

1.启动

启动以后软件自动加载当天的历史大事记,点击左侧的事件即可查看对应的事件详情。 img

2.日期切换

在旋钮组件(SpinBox)中选择一个日期,就会转到所选日期的大事件(字体、字体颜色、背景色可单独设置) img

1.整体流程

img

2.UI设计(草图)

3.UI设计(QT设计师)
