def openFileNameDialog(self):
options = QFileDialog.Options()
options |= QFileDialog.DontUseNativeDialog
fileName, _ = QFileDialog.getOpenFileName(self,"QFileDialog.getOpenFileName()", "","All Files (*);;Python Files (*.py)", options=options)
if fileName:
print(fileName)
For this code, this is my output ,
fileName, _ = QFileDialog.getOpenFileName(self,"QFileDialog.getOpenFileName()", "","All Files ();;Python Files (.py)", options=options) TypeError: getOpenFileName(parent: QWidget = None, caption: str = '', directory: str = '', filter: str = '', initialFilter: str = '', options: Union[QFileDialog.Options, QFileDialog.Option] = 0): argument 1 has unexpected type 'Ui_MainWindow'
How do I fix this ?
(Post Edit) : This is my GUI code :
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(443, 427)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.pushButton = QtWidgets.QPushButton(self.centralwidget)
self.pushButton.setGeometry(QtCore.QRect(350, 100, 75, 23))
self.pushButton.setObjectName("pushButton")
**self.pushButton.clicked.connect(self.openFileNameDialog)**
self.lineEdit = QtWidgets.QLineEdit(self.centralwidget)
self.lineEdit.setGeometry(QtCore.QRect(40, 100, 281, 21))
self.lineEdit.setObjectName("lineEdit")
MainWindow.setCentralWidget(self.centralwidget)
self.menubar = QtWidgets.QMenuBar(MainWindow)
self.menubar.setGeometry(QtCore.QRect(0, 0, 443, 21))
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.pushButton.setText(_translate("MainWindow", "Browse"))
The error is thrown when I run the python script.
Thanks for providing the GUI code. I believe the error most likely arises from inheritance complications. I am not sure why you are passing a separate MainWindow object to various functions. Instead, try to inherit from QMainWindow() and assign all the UI elements to self.
