d여기에서 Save your application setting values within a PyQt application | PyQt5 Tutorial – module ‘pyqt5.qtgui’ has no attribute ‘qapplication’ 주제에 대한 세부정보를 참조하세요
In this PyQt5 tutorial, we are going to look how to save application setting values within the PyQt application itself.
Users normally expect an application to remember its settings (window sizes and positions, options, etc.) across sessions. This information is often stored in the system registry on Windows, and in property list files on macOS and iOS. On Unix systems, in the absence of a standard, many applications (including the KDE applications) use INI text files.
QSettings is an abstraction around these technologies, enabling you to save and restore application settings in a portable manner.

## What is PyQt?
PyQt is a library created by Riverbank based on the Qt framework to let you build desktop applications in Python. (An alternative is PySide6, by Qt the company itself).
Qt framework itself is written in C++, and the framework is also available in other programming languages, such as Java and C++. By using Python, we can build applications much more rapidly.

Qt5: AttributeError: ‘module’ object has no attribute ‘QApplication’
System: 15.10 (Wily Werewolf) x64
Code:
# -*- coding: utf-8 -*- # Form implementation generated from reading ui file ‘test.ui’ # # Created by: PyQt5 UI code generator 5.5.1 # # WARNING! All changes made in this file will be lost! from PyQt5 import QtCore, QtGui, QtWidgets class Ui_Form(object): def setupUi(self, Form): Form.setObjectName(“Form”) Form.resize(400, 300) self.pushButton = QtWidgets.QPushButton(Form) self.pushButton.setGeometry(QtCore.QRect(120, 120, 85, 26)) self.pushButton.setObjectName(“pushButton”) self.retranslateUi(Form) QtCore.QMetaObject.connectSlotsByName(Form) def retranslateUi(self, Form): _translate = QtCore.QCoreApplication.translate Form.setWindowTitle(_translate(“Form”, “Form”)) self.pushButton.setText(_translate(“Form”, “PushButton”)) if __name__ == ‘__main__’: app = QtGui.QApplication(sys.argv) ex = Ui_Form() ex.show() sys.exit(app.exec_())
I get the following error:
app = QtGui.QApplication(sys.argv) AttributeError: ‘module’ object has no attribute ‘QApplication’
Basically, I designed the GUI with the Qt5 and then used pyuic5. I already installed PyQt5, not sure if the installation went through as expected.

Any help will be highly appreciated.

Qt5: AttributeError: ‘module’ object has no attribute ‘QApplication’
I am not sure how your main function was generated. I tried to replicate it with what seems to be the same version of pyuic5. I am calling it with the commandline pyuic5 -x untitled.ui (where the ui as in your case just contains a PushButton in a Widget). The -x option has the effect: ‘The generated Python code includes a small amount of additional code that creates and displays the GUI when it is executes as a standalone application.’ (http://pyqt.sourceforge.net/Docs/PyQt5/designer.html) The result I get is
# -*- coding: utf-8 -*- # Form implementation generated from reading ui file ‘untitled.ui’ # # Created by: PyQt5 UI code generator 5.5.1 # # WARNING! All changes made in this file will be lost! from PyQt5 import QtCore, QtGui, QtWidgets class Ui_Form(object): def setupUi(self, Form): Form.setObjectName(“Form”) Form.resize(400, 300) self.pushButton = QtWidgets.QPushButton(Form) self.pushButton.setGeometry(QtCore.QRect(70, 50, 75, 23)) self.pushButton.setObjectName(“pushButton”) self.retranslateUi(Form) QtCore.QMetaObject.connectSlotsByName(Form) def retranslateUi(self, Form): _translate = QtCore.QCoreApplication.translate Form.setWindowTitle(_translate(“Form”, “Form”)) self.pushButton.setText(_translate(“Form”, “PushButton”)) if __name__ == “__main__”: import sys app = QtWidgets.QApplication(sys.argv) Form = QtWidgets.QWidget() ui = Ui_Form() ui.setupUi(Form) Form.show() sys.exit(app.exec_())
which has a different main function. The rest of the code is equivalent.
Qt5: AttributeError: ‘module’ object has no attribute ‘QApplication’
from PyQt5 import QtCore, QtGui, QtWidgets # Import the PyQt5 module we’ll need import sys # We need sys so that we can pass argv to QApplication import design # This file holds our MainWindow and all design related things # it also keeps events etc that we defined in Qt Designer import os # For listing directory methods class ExampleApp(QtWidgets.QMainWindow, design.Ui_MainWindow): def __init__(self): # Explaining super is out of the scope of this article # So please google it if you’re not familar with it # Simple reason why we use it here is that it allows us to # access variables, methods etc in the design.py file super(self.__class__, self).__init__() self.setupUi(self) # This is defined in design.py file automatically # It sets up layout and widgets that are defined self.btnBrowse.clicked.connect(self.browse_folder) # When the button is pressed # Execute browse_folder function def browse_folder(self): self.listWidget.clear() # In case there are any existing elements in the list directory = QtGui.QFileDialog.getExistingDirectory(self, “Pick a folder”) # execute getExistingDirectory dialog and set the directory variable to be equal # to the user selected directory if directory: # if user didn’t pick a directory don’t continue for file_name in os.listdir(directory): # for all files, if any, in the directory self.listWidget.addItem(file_name) # add file to the listWidget def main(): app = QtGui.QApplication(sys.argv) # A new instance of QApplication form = ExampleApp() # We set the form to be our ExampleApp (design) form.show() # Show the form app.exec_() # and execute the app if __name__ == ‘__main__’: # if we’re running file directly and not importing it main() # run the main function
I get the error :
app = QtGui.QApplication(sys.argv) AttributeError : ‘module’ object has no attribute ‘QApplication’
I have a “design.py” which is the gui of my application. This code is my “main.py” that’s suppose to show and execute the app. But I got that error. Not sure what is wrong. Thank you in advance.

初次用Python制作图形界面，遇到了这个问题
AttributeError: module ‘PyQt5.QtGui’ has no attribute ‘QApplication’
代码如下：
from PyQt5 import QtCore, QtGui, QtWidgets class Ui_MainWindow (object) : def setupUi (self, MainWindow) : MainWindow.setObjectName( “MainWindow” ) MainWindow.resize( 520 , 401 ) self.centralwidget = QtWidgets.QWidget(MainWindow) self.centralwidget.setObjectName( “centralwidget” ) self.quitButton = QtWidgets.QPushButton(self.centralwidget) self.quitButton.setGeometry(QtCore.QRect( 350 , 260 , 91 , 51 )) self.quitButton.setAutoDefault( False ) self.quitButton.setDefault( False ) self.quitButton.setFlat( False ) self.quitButton.setObjectName( “quitButton” ) MainWindow.setCentralWidget(self.centralwidget) self.menubar = QtWidgets.QMenuBar(MainWindow) self.menubar.setGeometry(QtCore.QRect( 0 , 0 , 520 , 23 )) self.menubar.setObjectName( “menubar” ) MainWindow.setMenuBar(self.menubar) self.statusbar = QtWidgets.QStatusBar(MainWindow) self.statusbar.setObjectName( “statusbar” ) MainWindow.setStatusBar(self.statusbar) self.retranslateUi(MainWindow) QtCore.QMetaObject.connectSlotsByName(MainWindow) def retranslateUi (self, MainWindow) : _translate = QtCore.QCoreApplication.translate MainWindow.setWindowTitle(_translate( “MainWindow” , “MainWindow” )) self.quitButton.setText(_translate( “MainWindow” , “quit” )) if __name__ == “__main__” : import sys app=QtWidgets.QApplication(sys.argv) widget=QtWidgets.QWidget() ui=Ui_MainWindow() ui.setupUi(widget) widget.show() sys.exit(app.exec_())
查了一些资料后发现：我用qt designer创建的是一个mainwindow，而不是wideget或者dialog,所以需要把
widget=QtWidgets.QWidget()
改成
widget=QtWidgets.QMainWindow()
然后界面就出来啦~~~
