AttributeError: 'Ui_MainWindow' object has no attribute 'selectButton'

AttributeError: 'Ui_MainWindow' object has no attribute 'selectButton'这个错误通常表示在UI文件中没有名为'selectButton'的控件。根据引用中的描述，可能是因为你在UI文件中误用了一个不可编辑的按钮，而正确的控件应该是'plainTextEdit'。请确保在UI文件中使用了正确的控件名称来解决这个问题。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
