# Objective Implement minimal multi-click support. Add double click to select word and triple click to select all support to text input widgets. Fixes #23874 ## Solution New `MULTI_CLICK_DURATION` constant that sets the max time between clicks for them to count as consecutive. Added a field `count` to `Click`. 1 is a single click, 2 is a double click, 3 is a triple click and so on. It's a `u8` and saturates at 255 if you click that many times. Current multi-click state is stored in a field `clicking` on `PointerButtonState`. The `clicking` state is cleared after `MULTI_CLICK_DURATION` without another click. New `SelectWordAtPoint` `TextEdit`. New observer system `on_pointer_click` in `bevy_ui_widgets::text_input`. This queues `SelectWordAtPoint` for 2 clicks and `SelectAll` for 3 or more. `Click` events are dispatched on release, so they happen after `Press`. The `Press` for a double click might move the cursor but that doesn't affect the `SelectWordAtPoint` edit that is dispatched. # The implementation is deliberately minimal, I just added here what was needed for the text input. Left for followups: - Tracking the initial click position and returning the displacement with `Click`. - Spatial tolerance (clicks are only multi-clicks if the pointer hasn't moved too far). - Configurable multi-click duration. We could add a separate `MultiClick` event instead. It seems to me things would be more complicated with both `Click` and `MultiClick` observer systems though. ## Testing Text inputs now support double click to select a word and triple click to select all: ``` cargo run --example multiline_text_input ``` --------- Co-authored-by: Alice Cecile <alice.i.cecile@gmail.com> Co-authored-by: Talin <viridia@gmail.com>
