self.ui对象上“安装” GUI，因此ui上的每个小部件实际上都可以作为self.ui.someWidget进行访问。而且，QTextEdit没有text()属性，但是toPlainText()：
toPlainText()
我建议您从不编辑用
def otpravit_naz(self): print("1") textboxValue = self.ui.textEdit.toPlainText() print(textboxValue)生成的文件，但始终将它们用作导入的模块；阅读更多关于pyuic的信息；另外，请注意在主窗口小部件上而不是在其子窗口上设置主布局，并将所有内容添加到该布局中，否则，每当调整窗口大小时，子窗口小部件都可能被隐藏。
