QFileDialog view folders and files but select folders only?

Question

I\'m creating my own custom file dialog using the following code:

file_dialog = QtGui.QFileDialog()
file_dialog.setFileMode(QtGui.QFileDialog.Directory)
file

To prevent files being selected, you can install a proxy model which manipulates the flags for items in the file-view:

dialog = QFileDialog()
dialog.setFileMode(QFileDialog.Directory)
dialog.setOption(QFileDialog.DontUseNativeDialog, True)

class ProxyModel(QIdentityProxyModel):
    def flags(self, index):
        flags = super(ProxyModel, self).flags(index)
        if not self.sourceModel().isDir(index):
            flags &= ~Qt.ItemIsSelectable
            # or disable all files
            # flags &= ~Qt.ItemIsEnabled
        return flags

proxy = ProxyModel(dialog)
dialog.setProxyModel(proxy)

dialog.exec()
