当 wxpython 中的文件夹中不存在图像时，框架不会打开
frame does not open when image is not present in folder in wxpython
'''
在下面的代码中，我在三个不同的面板中显示文件夹中的图像。在这里我遇到了一个问题，问题是当文件夹中没有任何图像时，wxpython 框架不会打开，但代码执行完美，没有任何错误。主要问题是框架打不开。即使文件夹中不存在图像，如何放置任何逻辑来显示框架。'''

即使没有图像，您也需要在 sizer 中添加一些内容。
我没有编辑你的代码，而是升级了以前的答案，因为你的代码混合了位置放置和大小调整器，这最终会给你带来麻烦。
