pyQt5 AttributeError:'布尔'对象没有属性'txtCustCode' [英] pyQt5 AttributeError: 'bool' object has no attribute 'txtCustCode'

问题描述

使用QT Designer设计代码.然后使用pyuic5 -x productentryscreen.ui > productentryscreen3.py命令生成python代码. 我正在使用按钮和文本框.当按下按钮时，我要显示在QlineEdit框中输入的值. 但是单击btnCancel时出现错误"AttributeError:'bool'对象没有属性".这是引发错误(我认为)textboxValue = self.txtCustCode.text的地方.我什至尝试了textboxValue = self.txtCustCode.text() 以下是代码

Using QT Designer to design the code. Then using the pyuic5 -x productentryscreen.ui > productentryscreen3.py command to generate python code. i am using buttons and textboxes. when a button is pressed i want to display value entered in the QlineEdit box. But i am getting the error " AttributeError: 'bool' object has no attribute" when the btnCancel is clicked. This is where the error is thrown (i presume) textboxValue = self.txtCustCode.text. i even tried with textboxValue = self.txtCustCode.text() Following is the code

推荐答案

下面的行返回布尔值.

self.txtCustCode = QLineEdit(self.centralwidget)

然后，您尝试使用setGeometry属性.这就是为什么它会给您错误.

Then you are trying to using setGeometry attribute. That's why it gives you error.

self.txtCustCode.setGeometry(QtCore.QRect(230, 160, 211, 20))
self.txtCustCode.setObjectName("txtCustCode")
