用button 和QFileDialog打开文件夹 没啥问题
self.pushButton.clicked.connect(self.openfile)后
def openfile(self): openfile_name = QFileDialog.getOpenFileName(self,'选择文件','','Excel files(*.xlsx , *.xls)')
但用菜单栏里的action 和QFileDialog打开文件夹会报错
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'
请问大神们菜单栏里的action如何打开文件夹
