Hey! Does anyone from #GNOME or that works with GNOME technologies know how I can make my #python #GTK4 / #Libadwaita app run in the background when closing ? And how to make it appear correctly in GNOME background app menu, or even in the AppIndicator extension ?
Any link to relevant documentation will be useful ! :)
Thank you in advance!
@krafting you can use the background portal through libportal: https://libportal.org/method.Portal.request_background.html
Or you can call the DBus method directly: https://flatpak.github.io/xdg-desktop-portal/docs/doc-org.freedesktop.portal.Background.html
@ebassi Thank you, i'll try this XdpPortal thingy!
@krafting the basics are:
1. request background access
2. if successful, call Gio.Application.hold() to keep the instance alive even if the window is closed
3. on failure, log the issue and continue as normal
@ebassi Welp, I got it almost working. I get an error when trying to compile the flatpak thogh...
"ValueError: Namespace Xdp not available"
I import Xdp in python using
gi.require_version('Xdp', '1.0')
from gi.repository import Xdp
It works by running the script with python script.py but not in the flatpak...
Doesn't the org.gnome.Sdk/47 comes with Xdp ?
@krafting no, libportal is not currently in the run time, I'm afraid; you need to build it inside your manifest, like this: https://github.com/flathub/re.sonny.Workbench/blob/master/modules/libportal.json
It's enough to build the library: it comes with its own introspection data that can be loaded by pygobject.
@ebassi do you know if it ever will be in the runtime ?
And thank you very much for the info, I'll try to build it then and use it this way !
@krafting it's a complicated question; libportal is not a stable API, so shipping it in the run time could cause issues when updating the dependency in applications: https://gitlab.gnome.org/GNOME/gnome-build-meta/-/issues/496
@ebassi yeah I understand, maybe in the future then!
