我已经创建了一个ui文件，[[window.ui（由一个选项卡小部件组成））和一个小部件文件（[student（某些按钮，功能）），然后使用qtDesigner创建了pyic5格式的py文件。并继承一个单独的文件，例如mainWindow.py和mainStudent.py。
我在mainWindow.py中添加了一个tabWidget，我想从tab调用页面student.py。因此，我创建了一个新文件app.py，在该文件中，我首先从mainWindow.py
继承了类，并添加了一个tab调用student，然后尝试从mainStudent.py继承该类。我的目标是如果我运行app.py，则mainWindo
w将与tabwidget一起出现，其中选项卡名称为“ student”，如果我单击了“学生”选项卡，则所有元素都会从“ mainStudent.py”显示。但我是遇到这个错误：尝试将QLayout“”添加到已经具有布局的StudentPage“ Form”（注意：功能正常））>我不知道我在哪里犯错了！请帮忙！
