For a desktop environment, it¢s helpful to know which execs caused which windows to be opened. One way of doing this is with the Freedesktop.org startup notification protocol, https://specifications.freedesktop.org/startup-notification-spec/startup-notification-latest.txt.
We currently partially support this protocol in GTK builds, because GTK handles it for us automatically. However, GTK can only automatically handle the simple case where emacs is launched and displays a window itself.
To support emacsclient, where the execed process is not necessarily an ancestor of the process displaying the window, as I understand it we¢d need to do the following:
- Pass the value of the DESKTOP_STARTUP_ID environment variable from emacsclient to emacs.
- When opening a new frame at the request of emacsclient, call C function gtk_window_set_startup_id with the value from DESKTOP_STARTUP_ID.
