# Objective Fix https://github.com/bevyengine/bevy/issues/4530 - Make it easier to open/close/modify windows by setting them up as `Entity`s with a `Window` component. - Make multiple windows very simple to set up. (just add a `Window` component to an entity and it should open) ## Solution - Move all properties of window descriptor to ~components~ a component. - Replace `WindowId` with `Entity`. - ~Use change detection for components to update backend rather than events/commands. (The `CursorMoved`/`WindowResized`/... events are kept for user convenience.~ Check each field individually to see what we need to update, events are still kept for user convenience. --- ## Changelog - `WindowDescriptor` renamed to `Window`. - Width/height consolidated into a `WindowResolution` component. - Requesting maximization/minimization is done on the [`Window::state`] field. - `WindowId` is now `Entity`. ## Migration Guide - Replace `WindowDescriptor` with `Window`. - Change `width` and `height` fields in a `WindowResolution`, either by doing ```rust WindowResolution::new(width, height) // Explicitly // or using From<_> for tuples for convenience (1920., 1080.).into() ``` - Replace any `WindowCommand` code to just modify the `Window`'s fields directly and creating/closing windows is now by spawning/despawning an entity with a `Window` component like so: ```rust let window = commands.spawn(Window { ... }).id(); // open window commands.entity(window).despawn(); // close window ``` ## Unresolved - ~How do we tell when a window is minimized by a user?~ ~Currently using the `Resize(0, 0)` as an indicator of minimization.~ No longer attempting to tell given how finnicky this was across platforms, now the user can only request that a window be maximized/minimized. ## Future work - Move `exit_on_close` functionality out from windowing and into app(?) - https://github.com/bevyengine/bevy/issues/5621 - https://github.com/bevyengine/bevy/issues/7099 - https://github.com/bevyengine/bevy/issues/7098 Co-authored-by: Carter Anderson <mcanders1@gmail.com> |
