按钮单击def'log_in'结果为'TypeError' 但是，当我将按钮更改为def'login_failed'时，则已经可以使用
我是PyQT5的新手，我不明白为什么会收到此错误。将创建def谁将检查登录名和密码文本标签，但我没有从中获得价值。用QT Creator创建的代码。
我的代码：
从PyQt5导入QtCore，QtGui，QtWidgets 从等待时间导入睡眠

TypeError：参数1具有意外的类型'QWidget'
答案 0 :(得分：0)
self.log_in = QtWidgets.QWidget(self.centralwidget)
您将log_in从功能重新定义为QTWidget。当您尝试调用log_in时，它会找到QTWidget，它不是可调用的函数。
