[Bug] Broken Linux symlink crashes Demo_Tree_Element.py

从 Demo_Tree_Element.py 开始，重点查看第 36 行，该行在将文件插入树中时使用了 os.stat(fullname)。使用包含损坏符号链接的目录重现该问题；当 demo 不再崩溃，并且受影响的条目在树中得到可见处理时，即视为完成。

[Bug] Broken Linux symlink crashes Demo_Tree_Element.py
When running the program against a directory tree that contains a broken file symbolic link, it crashes with a "file not found" error. Python throws an exception that isn't handled:
Traceback (most recent call last):
File "Demo_Tree_Element.py", line 38, in
add_files_in_folder('', starting_path)
File "Demo_Tree_Element.py", line 34, in add_files_in_folder
add_files_in_folder(fullname, fullname)
File "Demo_Tree_Element.py", line 34, in add_files_in_folder
add_files_in_folder(fullname, fullname)
File "Demo_Tree_Element.py", line 36, in add_files_in_folder
treedata.Insert(parent, fullname, f, values=[os.stat(fullname).st_size], icon=file_icon)
FileNotFoundError: [Errno 2] No such file or directory: '/home/ran/projects/net_tools/samplicator-master/depcomp'

This was obvious when I ran it from the command line, but from the Demo Browser it just silently disappeared

Troubleshooting

These items may solve your problem. Please check those you've done by changing - [ ] to - [X]

• Searched main docs for your problem www.PySimpleGUI.org
• Looked for Demo Programs that are similar to your goal. It is recommend you use the Demo Browser! Demos.PySimpleGUI.org
• None of your GUI code was generated by an AI algorithm like GPT
• If not tkinter - looked for Demo Programs for specific port
• For non tkinter - Looked at readme for your specific port if not PySimpleGUI (Qt, WX, Remi)
• Run your program outside of your debugger (from a command line)
• Searched through Issues (open and closed) to see if already reported Issues.PySimpleGUI.org
• Have upgraded to the latest release of PySimpleGUI on PyPI (lastest official version)
• Tried using the PySimpleGUI.py file on GitHub. Your problem may have already been fixed but not released

Detailed Description

When running the program against a directory tree that contains a broken file symbolic link, it crashes with a "file not found" error. Python throws an exception that isn't handled:
Traceback (most recent call last):
File "Demo_Tree_Element.py", line 38, in
add_files_in_folder('', starting_path)
File "Demo_Tree_Element.py", line 34, in add_files_in_folder
add_files_in_folder(fullname, fullname)
File "Demo_Tree_Element.py", line 34, in add_files_in_folder
add_files_in_folder(fullname, fullname)
File "Demo_Tree_Element.py", line 36, in add_files_in_folder
treedata.Insert(parent, fullname, f, values=[os.stat(fullname).st_size], icon=file_icon)
FileNotFoundError: [Errno 2] No such file or directory: '/home/ran/projects/net_tools/samplicator-master/depcomp'

This was obvious when I ran it from the command line, but from the Demo Browser it just silently disappeared

Code To Duplicate

The Demo_Tree_Element.py file included with the package.

This pre-formatted code block is all set for you to paste in your bit of code:

# Paste your code here

To fix, replace line 36 with something like:

            try:
                treedata.Insert(parent, fullname, f, values=[os.stat(fullname).st_size], icon=file_icon)
            except:
                treedata.Insert(parent, fullname, f, values=["???? error"], icon=file_icon)
