# Objective The new `bevy_input_focus` crates has a tool to bubble input events up the entity hierarchy, ending with the window, based on the currently focused entity. Right now though, this only works for keyboard events! Both `bevy_ui` buttons and `bevy_egui` should hook into this system (primarily for contextual hotkeys), and we would like to drive `leafwing_input_manager` via these events, to help resolve longstanding pain around "absorbing" / "consuming" inputs based on focus. In order to make that work properly though, we need gamepad support! ## Solution The logic backing this has been changed to be generic for any cloneable event types, and the machinery to make use of this externally has been made `pub`. Within the engine itself, I've added support for gamepad button and scroll events, but nothing else. Mouse button / touch bubbling is handled via bevy_picking, and mouse / gamepad motion doesn't really make sense to bubble. ## Testing The `tab_navigation` example continues to work, and CI is green. ## Future Work I would like to add more complex UI examples to stress test this, but not here please. We should take advantage of the bubbled mouse scrolling when defining scrolled widgets. |
