PyQt5 QFileDialog迟滞问题临时解决

作者:互联网

PyQt5 QFileDialog.getExistingDirectory

date: 2021-06-11

问题说明

获取图像所在文件夹,然后返回路径将其更新到textBrowser中。测试发现win10下会选择完路径后很久才返回文件夹地址,但该现象出现在我更新系统后,不知原因。

img_dir_path = QFileDialog.getExistingDirectory(self,
                                                caption='Select Image Directory',
                                                directory=os.getcwd())
self.image_path_line.setText(str(img_dir_path))

解决办法

The QFileDialog constructor creates a Qt dialog, whereas the static functions (like getSaveFileName) will create a native one (unless the DontUseNativeDialog option is set to True).

无法保证系统的NativeDialog比qt自带的快,但是测试发现qt自带的速度更快。所以有解决办法:

img_dir_path = QFileDialog.getExistingDirectory(self,
                                                caption='Select Image Directory',
                                                directory=os.getcwd(),
                                                options=QFileDialog.DontUseNativeDialog)
self.image_path_line.setText(str(img_dir_path))

或者直接输入文件夹路径。
