# Objective Expose the `winit` functions [drag_window](https://docs.rs/winit/latest/winit/window/struct.Window.html#method.drag_window) and [resize_window](https://docs.rs/winit/latest/winit/window/struct.Window.html#method.drag_resize_window). Which allows implementing move & resize for windows without decorations. ## Solution Add the functions `start_drag_move` and `start_drag_resize` to `bevy_window::Window`, which are then assigned to fields in `InternalWindowState`, and propagated to `winit` in the `changed_windows` system. ## Testing I've tested that both functions works on x11 and wayland. Not sure if someone needs to test on windows/mac? --- ## Showcase [Screencast from 2024-10-06 11-49-58 (trimmed).webm](https://github.com/user-attachments/assets/1cdee7b1-22bd-41d3-8a0a-6872a6ebf62c) (The flickering in the video is some issue with resizing without decorations on x11) <details> <summary>Click to view showcase</summary> Not the same code used in the video, but simple way to test moving a window without decorations. ```rust use bevy::prelude::*; fn main() { App::new() .add_plugins(DefaultPlugins.set(WindowPlugin { primary_window: Some(Window { decorations: false, ..default() }), ..default() })) .add_systems(Update, move_windows) .run(); } fn move_windows(mut windows: Query<&mut Window>, input: Res<ButtonInput<MouseButton>>) { if input.pressed(MouseButton::Left) { for mut window in windows.iter_mut() { window.start_drag_move(); } } } ``` </details> --------- Co-authored-by: Alice Cecile <alice.i.cecile@gmail.com> |
