前置：

QButtonGroup、QRadioButton、QGroupBox

QCheckBox

QInputDialog

前置：

1 本系列将以 “PyQt6基础_”开头，放在【PyQt6基础】专栏
2 本文只将界面控件简单讲述，后续博文会对一些控件进一步讲解，会统一放在这个系列里
3 本系列后续会在B站录制视频，到时会在文末贴出链接。本人还是建议先看博文，不懂的再看视频，这样效率高，节约时间。

注意：以下链接虽然是PySide6的官方文档，但PyQt6大部分都通用。

1 QButtonGroup QRadioButton QGroupBox 在实际开发过程中，这三个控件总是一起使用，就放在一起讲解

2 QButtonGroup只是作为多个按钮的管理，没有界面，就不存在需要放入layout的情况。QButtonGroup中放入的按钮要指定一个id，如果设置为 -1，程序会自动分配id，程序自动分配的id是负数，从-2开始，所以建议手动配置的id设置为正数，避免冲突。

3 QGroupBox 直接设置布局，不直接放控件

4 QRadioButton 如果一个界面中有多组QRadioButton就必须分组

QCheckBox

1 这里也使用了QButtonGroup来管理QCheckBox组。这里和QRadioButton不同，在一个界面中有多组QCheckBox不是必须用QButtonBroup来分组，直接代码上做好识别也可以。

2 QButtonGroup比较适合QRadioButton使用，本身的设计也是契合QRadioButton使用的。所以把QButtonGroup用于QCheckBox时，需要.setExclusive(False)，这个值默认是True。exclusive的作用是标识按钮组任何时候只有一个可以选中，不能选中多个。复选框QCheckBox一般用来做多选，所以要将exclusive设为False

QInputDialog

https://doc.qt.io/qtforpython-6/PySide6/QtWidgets/QInputDialog.html QInputDialog官方文档

from PyQt6.QtCore import Qt,QSize,QDate
from PyQt6.QtWidgets import (
