QFileDialog that accepts a single file or a single directory

Is it possible to show a QFileDialog where the user can select a file or a directory, either one?

QFileDialog::getOpenFileName() accepts only files, while

Answer 1

Connect to the currentChanged signal and then set the file mode to the currently selected item (directory or file). This is a Python3 implementation:

class GroupFileObjectDialog(QFileDialog):

    def __init__(self, parent):
        super().__init__(parent)
        self.setOption(QFileDialog.DontUseNativeDialog)
        self.setFileMode(QFileDialog.Directory)
        self.currentChanged.connect(self._selected)

    def _selected(self,name):
        if os.path.isdir(name):
            self.setFileMode(QFileDialog.Directory)
        else:
            self.setFileMode(QFileDialog.ExistingFile)
