1 安装环境

1）Python环境安装PyQt5、PyQt-sip、PyQt5Designer、PyQt5-tools
2）在环境下\Lib\site-packages\QtDesinger\designer.exe，打开designer.exe应用程序。

2 Ctrl+N，新建Main Window窗口，保存为checkBox.ui文件

在这里插入图片描述

3 CheckBox的三种状态

1）QT.Cheched—>选中
2）QT.PartialyChecked—>半选中
3）QT.Unchecked—>未选中

4 实现通用复选框的选中状态设置用户权限功能

1）在Qt Designer设计器中选中5个Checkbox控件和一个设置按钮pushbutton，选中双击每个文本设置如下：
在这里插入图片描述
2）保存为.ui文件，并使用Python环境中的Scripts\pyuic5.exe程序转换为.py文件：

pyuic5.exe -o checkBox.py checkBox.ui

在这里插入图片描述
3）修改生成的.py文件，如下：
