Hello, I'm using Telegram Desktop Flatpak on GNU/Linux and drag & drop doesn't work from Thunar of XFCE. It says "Could not send an empty file..."

Flatpak applications run in a restricted sandboxes. Check this: https://github.com/flatpak/xdg-desktop-portal/issues/99

so won't fix? (because it cannot be fixed)

They are talking about adding a Mimetype "application/x-file-contents" or something like that to the *.desktop file? and some other possible solutions... I tried but it doesn't work.

But if I put the file in the sandbox home folder of Telegram it works perfectly (/home/user/.var/app/org.telegram.desktop/picture.png), but that is a little annoying. Yeah, maybe I can make a link to that folder to make the things easier. But if it can't be fixed and use the routes outside of the sandbox only for drag & drop in the future, it would be very sad...

Thanks for the help :)

The link doesn't work either... Only if I access manually to the original path... But I don't understand because if I install a file explorer from Flatpak, this can access to host paths... And also I can drag and drop between a host file explorer to a flatpack file explorer

[darksystem23]

I fixed with flatpak override --user --filesystem=home org.telegram.desktop the user has to set the override. It's simple like that

This is not a fix. You have just disabled isolation and divided the whole point of Flatpak to zero.

Flatpak is a next-generation technology for building and distributing desktop applications on Linux

The point of Flatpak is not sandbox but having an easy way to distribute binaries without having to care about different Linux distributions. https://www.flatpak.org/ does not even mention sandboxing once.

That depends on what perspective you are looking at and what purposes

This is just not true. The wiki page starts with that. I would advise reading more about Flatpak that their front page that's supposed to be short
