my code

def selectResourceFile(self):
    # 资源文件路径
    resourceFile = QFileDialog.getOpenFileName(self, caption='选择资源文件', dir=os.getcwd(), filter='All Files (*)')
    if resourceFile[0] not in ['', None]:
        # 插入表格内容
        self.ui.tableWidget.insertRow(0)  # 插入到第一行
        self.setTable(0, 0, resourceFile[0])
        self.setTable(0, 1, '.')

@SGaist
Same result in 6.4.2!

Based on this thread of the Apple developer forum, it looks like an Apple issue.

@maccan , @SGaist , all,

In my case, I could fix the problem by using the QFileDialog::DontUseNativeDialog option.

When using that option, the Apple native file dialog window is not used anymore, which seems to fix the problem in my application (on macOS Ventura and M1 Pro chip).

I hope that helps.

Best,

@Riccardo-M-Bianchi

I am running into this same issue (Mac OS, Ventura, M1 chip, etc), but I am using QML and following the basic QT manual page for opening a QML folder dialogue: https://doc.qt.io/qt-6/qml-qt-labs-platform-folderdialog.html#:~:text=To show a folder dialog,made by accepting the dialog.

Does anyone know if there is a way to set the QFileDialog::Don'tUseNative option from within QML?

    QStringList fileNames = QFileDialog::getOpenFileNames(
        this, tr("Import File(Import tif files first)"), filePath,
        "file (*.tiff *.tif *.png *.bmp)",0,QFileDialog::DontUseNativeDialog);

QFileDialog::DontUseNativeDialog

add up option，program could work，but way？

[SGaist]

@ShineGalaxy because then the native dialog is not used and thus does not trigger the message.

@SGaist add tifflib-4.5.1，then problem occurred. why?
