Philipp Schaffrath 166f044fd0 gpui: Linux wayland set exclusive zone and edge (#60163) ... # Objective The exclusive zone and exclusive edge of a wlr-layer-shell surface could only be set once, at creation, through `LayerShellOptions`. This adds runtime setters so a live layer-shell window such as a panel can update them without being recreated. ## Solution Add two methods on `Window`: - `set_exclusive_zone` updates how much screen space the surface reserves. A positive value reserves that distance from the anchored edge, 0 lets the surface be moved out of others' exclusive zones, and -1 ignores reserved space and may extend under other surfaces. - `set_exclusive_edge` chooses which anchored edge the exclusive zone applies to, which is needed to disambiguate a corner-anchored surface. Setting an exclusive edge the surface is not anchored to is a fatal protocol error, so the edge is validated (it must be a single edge that the surface anchor contains) and an invalid edge is logged and ignored. The same validation now also guards the creation path. Both setters only commit the surface when a change actually applies, and are no-ops on non-layer-shell windows and on other platforms. This is where these 2 are documented: https://wayland.app/protocols/wlr-layer-shell-unstable-v1#zwlr_layer_surface_v1:request:set_exclusive_zone https://wayland.app/protocols/wlr-layer-shell-unstable-v1#zwlr_layer_surface_v1:request:set_exclusive_edge ## Testing - Verified with a small local layer-shell window (a top bar anchored TOP, LEFT, RIGHT) with buttons that call the setters at runtime - No automated test was added, since this calls through to the compositor. - Reviewers without a layer-shell capable compositor (for example GNOME/Mutter) cannot exercise this, as `zwlr_layer_shell_v1` is unavailable there, I tested this on the [Smithay](https://github.com/Smithay/smithay/) based compositor [niri](https://github.com/niri-wm/niri) ## Self-Review Checklist: - [x] I've reviewed my own diff for quality, security, and reliability - [x] Unsafe blocks (if any) have justifying comments - [x] The content adheres to Zed's UI standards ([UX/UI](https://github.com/zed-industries/zed/blob/main/CONTRIBUTING.md#uiux-checklist) and [icon](https://github.com/zed-industries/zed/blob/main/crates/icons/README.md) guidelines) - [ ] Tests cover the new/changed behavior - [x] Performance impact has been considered and is acceptable --- Release Notes: - N/A		2026-07-15 08:18:46 +00:00
