Use Desktop Portal for Linux Sandbox Compatibility

[RayJW]

It seems like at the moment, this crate doesn't use the xdg-desktop-portal API for trashing files. Sadly, this means that it doesn't behave correctly in sandboxed environments like e.g. Flatpak packages.

It would be great if that could be changed, and I think it would benefit the code in general, as that would be the preferred way to ensure that any usual Linux cases are handled properly. More on this can be read here, where the reasons are explained.

That's great, thanks so much for sharing!

If this API is available on the platform, I also think it would make sense to use it, particularly if it also works for non-sandboxed applications. After all, the current implementation is very 'manual', which would never be the preferred choice here.

Yes, definitely. The API is completely independent of how the application is packaged and works across basically all Linux distros (at least I wouldn't know of any half modern distro not shipping the xdg desktop portals). It was initially designed to make sandboxed applications more isolated, but it still offers many advantages to traditional applications, like being compatible with permission based settings etc.

That's why one of the docs pages I've shared does say: "App developers are encouraged to use portal APIs even for unsandboxed apps".

After all, the current implementation is very 'manual', which would never be the preferred choice here.

For sure, I saw that and thought this must be a lot of work that the portals are already doing for you.

That's great to hear, thanks for elaborating.

And most importantly, portals are very likely to do this correctly. I am not so sure about the implementation here.
