1. Brief introduction
QT->tabWidget: tab page.
Customize the pull control through the toolbar in the ui, where tabwidget can create multiple tab pages, and two tab_widgets (tab_1/tab_2) are generated by default. And you can freely add tabs such as control deletion by right-clicking in the UI. Switching tabs is to switch widgets.
2. Customized use
If you want to use tabwidget more flexibly, or decouple the page. Then a solution that comes to mind is to separate the ui-widget from the tabwidget and insert the widget through the tabwidget function method.
2.1 Add controls
Interface settings, drag the control into the window and delete the default two tabs
2.2 Custom widgets
Customize the page you want to put in the tabwidget (custom ui-widget)
2.3 Add widget to tab_widget
Add custom ui-widget to tab through the method in tabwidget class

ui->tabWidget->addTab(m_userWidget, QString("个人信息"));
