'Ui_Form' object has no attribute 'comboBox'怎么改正

这个错误通常是因为你在代码中引用了一个名为`comboBox`的属性或方法,但实际上该属性或方法不存在于`Ui_Form`对象中。
可能的原因是你在设计界面时没有给组件设置正确的名称或对象名称,或者在代码中访问组件时使用了错误的名称。
如果你使用Qt Designer创建了UI文件,请确保你正确地给每个组件设置了名称或对象名称。可以在属性编辑器中查看和修改这些属性。
如果你是手动编写UI代码,请确保你正确地引用了组件的名称或对象名称。可以通过使用`self.findChild()`或`self.ui.<component_name>`来访问组件。

Ui_MainWindow object has no attribute retranslateUi
As an AI language model, I cannot see your code, so I can only provide a general solution.
This error occurs when you try to access an attribute called "retranslateUi" that does not exist in the Ui_MainWindow object. This attribute is typically generated by the PyQt5 or PySide2 UI compiler when you create a new UI file in Qt Designer and convert it to Python code.
To fix the error, you need to make sure that your UI file has been properly converted to Python code and that the "retranslateUi" method is defined in the class that inherits from Ui_MainWindow. Here are some steps you can take:
1. Make sure that you have converted your UI file to Python code using the PyQt5 or PySide2 UI compiler. You can do this by running the following command in your terminal or command prompt:
```
pyuic5 <ui_file_name>.ui -o <python_file_name>.py
```
Replace <ui_file_name> with the name of your UI file (including the .ui extension) and <python_file_name> with the name of the Python file you want to generate (including the .py extension).
2. Open the Python file that was generated by the UI compiler and look for the class that inherits from Ui_MainWindow. This class should have a method called "retranslateUi" that is used to translate the text of your UI elements to different languages.
3. If the "retranslateUi" method is missing, you can add it manually to your class definition. Here's an example of what the method should look like:
```
def retranslateUi(self, MainWindow):
_translate = QtCore.QCoreApplication.translate
MainWindow.setWindowTitle(_translate("MainWindow", "My Application"))
self.pushButton.setText(_translate("MainWindow", "Click Me!"))
# Add more translations for your UI elements here
```
Make sure to replace "MainWindow" with the name of your main window object, and add translations for all of your UI elements that need to be translated.
4. Save your Python file and run your application again. The "retranslateUi" method should now be called correctly and your UI elements should be translated properly.
I hope this helps! Let me know if you have any other questions.
如何处理Ui_MainWindow object has no attribute retranslateUi
这个错误通常出现在 PyQt5 的程序中,是因为在使用 Qt Designer 设计界面时,修改了窗口标题或其他文本内容,但是没有重新生成 Python 代码。解决方法是重新生成代码。
在 Qt Designer 中打开 .ui 文件,然后在菜单栏中选择 File -> Save As,将保存文件名设置为 ui_***.py(*** 为文件名),保存到项目文件夹中。
在 Python 代码中导入生成的 Python 文件,例如:
```
from PyQt5.QtWidgets import QApplication, QMainWindow
from ui_mainwindow import Ui_MainWindow
class MainWindow(QMainWindow):
def __init__(self):
super().__init__()
self.ui = Ui_MainWindow()
self.ui.setupUi(self)
```
注意,生成的 Python 文件的类名为 Ui_MainWindow,而不是 MainWindow。
如果重新生成代码后仍然出现该错误,可能是因为代码中的变量名与界面文件中的变量名不一致,可以在 Qt Designer 中打开界面文件,然后在 Object Inspector 中查看控件的 ObjectName,确保在 Python 代码中使用的变量名与 ObjectName 一致。
