5.00 and Electron 14

[vchernin]

If this works this is the first Flatpak app on Electron 14 with the portal file chooser (that I know of).
Only for testing purposes since its an RC.

I have no idea why this is so much trouble...
I tried flatpak run --env=GTK_USE_PORTAL=1 com.mattermost.Desktop on various distros and it's just not working.

@squalou @tristan957 I can't get this Electron 14 app working with the file chooser portal either... any ideas?

If not I think I'll open up an issue in electron's repo.

Edit: Maybe it's because of the changes to this file since the PR was merged.

[tristan957]

I don't think you need to set GTK_USE_PORTAL=1 within the flatpak itself. The portal should "just work" ™️

I recommend hopping into #flatpak on matrix.org. I would also recommend checking getting a d-bus monitor and watching the the calls to see if any portal action is happening. Also make sure you have the portal actually installed on the host machine

[tristan957]

I see you are already in the room. Someone there might have some sage advice.

[vchernin]

Yeah I don't see any calls to FileChooser in Bustle.. and I've asked in #flatpak a couple times but I didn't get any response. I'm afraid this issue is in unknown territory.

The portal defintely works with other apps just fine (well ones that support it anyway). I'm on Fedora so I usually like trying out shiny Linux stuff :)

[tristan957]

Honestly I have no clue. The user experience behind these features seems very hard to discover.

I assuming you already checked that xdg-desktop-portal-kde installed and xdg-desktop-portal-gnome/gtk is not installed and that GTK_USE_PORTAL=1 is exported in your host environment?

I guess that question was redundant with your previous message. You could try debugging electron and seeing if it hits the gtk native file chooser code path.

I made an issue for this, hopefully someone has some ideas on what’s wrong electron/electron#31258

I don’t really know how to debug Electron, hopefully someone does though. If I find time one day maybe I’ll try figure it out.
