Add progress bar to the file input widget
Opened this issue · 3 comments
As the web server is located at the observatory, it is expected that users need to wait a bit to finish the file upload. It's not an issue for a relatively small file, but maybe problematic for a large file. It would be nice to have a progress bar of the file upload.
Describe the solution you'd like
Add a progress bar for the file upload widget to indicate the progress of the transfer.
Describe alternatives you've considered
Just ask users to wait for a while before proceeding to the next steps.
Additional context
There is a possibility discussed in the following thread.

I think it's not quite sustainable, so I'd like to wait for being incorporated in Panel. (maybe someone should help to send a PR...)
I disable the buttons at start. Once the first file is uploaded, the "validate" button becomes active. 6e94085
The FileDropper widget is available in the master. I've not yet tested, but sounds promising.
