# Objective Wayland windows have no way to restrict which parts of the surface accept pointer and touch input. This adds support for setting an input region, so events outside it pass through to whatever is below the window. This is useful for shaped or partially click-through windows. Clicks in green area can pass through the window, clicks in red area do not: <img width="1057" height="395" alt="image" src="https://github.com/user-attachments/assets/2039af62-e43b-4834-b877-edad2a8f5ccf" /> ## Solution Add `Window::set_input_region`, which takes `Option<&[Bounds<Pixels>]>`: - `Some(rects)` restricts pointer and touch input to the union of the rectangles, in window coordinates. - `Some(&[])` is an empty region, so the window receives no input at all and is fully click-through. - `None` resets the region to the default, so the whole window receives input again. On Wayland this maps to `wl_surface.set_input_region`, building a `wl_region` from the rectangles or clearing it for `None`, and commits so the change applies immediately rather than waiting for the next frame. The method is a no-op on other platforms. ## Testing Tested on Linux with Wayland. - Tested in my own GPUI application, which uses a fullscreen layer for overlays while allowing clicks outside of the rendered elements to be passed through to the underlying windows. - No automated test was added, since this calls through to the compositor and is checked by observing input routing. ## 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 |
