gr.FileExplorer does not update view when root_dir does not change.

[christian-kento-rasmussen]

Describe the bug

When auto updating a gr.FileExplorer component using gr.Blocks().load(every=1) the file tree does not update when a file is created. The file tree does only update when the root_dir variable changes.

As an example:

If I have gr.FileExplorer open in a folder it will show all files, however when i manually create a new file this file it not shown.
The file will only be shown if I change the root_dir to a new path and then back again to the old path.
This is shown in the code example below. (remember to create a new file in the first 10 seconds)

Expected behaviour:

The file tree will update each second to include any new files.

References

this was supposedly fixed in #6096 however it does not work.

Reproduction

import os
import time

import gradio as gr

start_time = time.time()

def set_work_dir():
    # Check if the time elapsed is between 10 and 12 seconds
    if time.time() - start_time > 10 and time.time() - start_time < 12:
        print("Changing work dir to subfolder for 2 seconds and then back again, file should then be shown.")
        # Return the subfolder path to update the root_dir of FileExplorer
        return os.getcwd() + "/qim3d"
    else:
        # Return the current working directory
        return os.getcwd() 

with gr.Blocks() as demo:
    # Create a FileExplorer widget with the root_dir set dynamically using set_work_dir function
    f = gr.FileExplorer(root_dir=set_work_dir())
    # Load the FileExplorer widget into the demo
    demo.load(lambda: gr.FileExplorer(root_dir=set_work_dir()), None, f, every=1)
    
demo.launch()

Severity

I can work around it

I also encountered the same problem. Is there any solution now?

I to have this problem on a more recent version (4.21.0)

+1 here. my work around is to temporarily change the root dir and back:

def update_file_explorer():
    return gr.FileExplorer(root_dir=file_root_tmp)
def update_file_explorer_2():
    return gr.FileExplorer(root_dir=file_root)

refresh_btn.click(update_file_explorer, outputs=file_explorer).then(update_file_explorer_2, outputs=file_explorer)

Can we periodically trigger this refresh_btn.click every x=1 seconds?
I've tried to add every=1 to each/ both the click and then call but it didn't work.

I have encountered a similar problem. Adding a refresh button but not actually updating gr.FileExplorer.
