From e0d6ad1d5e7e80321285a9b14ca3329289eb02e6 Mon Sep 17 00:00:00 2001 From: Jan-Marek Glogowski Date: Mon, 15 Jul 2019 16:20:10 +0200 Subject: xdg-shell: use case to change the app ID at runtime MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit LibreOffice is one big binary with explicit brandings for different application modules. This is represented in X11 by a different WM_CLASS setting for a window. The WM_CLASS is changed based on the loaded document at runtime. As a result LibreOffice already offers multiple desktop files with different icons, StartupWMClass entries and application names. This amendment of the set_app_id request just explicitly specifies the use case to change a surfaces' app ID at runtime, so a compositor implementor is made aware of it. Just as the WM_CLASS, a change of the app ID should result in an update of the propertes of a surface depending on the app ID, like the window icon specified in the desktop file or a re-grouping of the surfaces in a task manager.
