1 控件之间的伙伴关系
1.1 什么是伙伴关系？
- 其实说白了就是控件之间的关联关系，就是一个控件可以控件另一个控件；
- 比如某些窗口菜单的快捷键等。
1.2 如何来设置伙伴关系？
- 可以使用通过
Qt Designer中的Edit-编辑伙伴来实现；
1.3 一个实例
- 在
From Layout中放置两个Label，两个Text Edit，一个PushButton：
- 点击
Qt Designer中的Edit-编辑伙伴，按住鼠标左键，拖动控件之间的关系即可：
- 保存为
test013_partner.ui，并转成test013_partner.py:
# -*- coding: utf-8 -*-
# Form implementation generated from reading ui file 'test013_partner.ui'

# Created by: PyQt5 UI code generator 5.15.4

self.pushButton.setText(_translate("MainWindow", "登陆"))
2 Tab顺序如何设置？
2.1 什么是Tab顺序？
- 就是通过
Tab键来控制鼠标焦点的顺序；
- 比如几个文本框，鼠标首次焦点定位在第一个框，按
Tab键就会定位到下一个文本框。
2.2 如何设置Tab顺序？
- 通过
Edit-编辑Tab顺序来实现；
- 比如先拖动几个
Line Edit：
- 通过预览后，按住Tab键来观察鼠标的定位情况，是按照从第一个文本框到最后一个：
- 点击
Edit-编辑Tab顺序，可以看到默认的Tab顺序：
- 保存为
test014_tab.ui，转成test014_tab.py：
