As elsewhere, make sure objects that need to have a ownership up to the context, and use this ownership chain to find relevant components, such as the backend or the Wayland compositor object instance. wayland/data-device: Hook up data devices to seats They are tied to a seat - make that connection in struct fields too, so that related objects can get to the context via it. wayland: Don't get Wayland compositor via singleton getter This means via the ownership chain or equivalent. xwayland: Hook up manager to Wayland compositor Same applies to the drag-n-drop struct. xwayland: Make X11 event handling compositor instance aware This avoids finding it via singletons in the callee. xwayland: Don't get Wayland compositor from singleton xwayland: Pass manager when handling dnd event window/xwayland: Don't get Wayland compositor from singleton xwayland/grab-keyboard: Don't get backend from singleton xwayland: Don't get backend from singleton wayland: Always get the backend from the context This means traveling up the ownership chain or equivalent when necessary. wayland: Hook up data devices, offers and sources to the compositor This allows tying them to a context without going through any singletons. wayland: Don't get display from singleton xwayland: Don't get display from singleton tablet: Don't get display from singleton Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2718>
