Typically, support for this is plumbed through linking libSM, and GTK notably does not use it. Qt does, of course. This is one of the things I've had on my radar for quite some time. macOS-style automatic relaunch of applications is slated upstream for 6.1: https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/3523 Support for the Wayland protocol will come after, but the combination of the two approaches means that pretty much everything will be able to relaunch as desired in some form on restart. -- 真実はいつも一つ！/ Always, there's only one truth! -- _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
