makepad-event-action

To handle Makepad widget events and send actions, implement handle_event to process inputs like Hit::FingerDown, then use cx.action to emit typed actions upward to parent components.

Makepad event propagation flows downward for events like MouseDown and KeyDown, while actions flow upward, allowing parent widgets to capture and forward actions using capture_actions and ActionsBuf.

Yes, Makepad event handling patterns apply across desktop and mobile UIs, enabling consistent action emission and handling for MouseDown, KeyDown, and TouchUpdate events across different platforms.

The best way to capture actions from child widgets in Makepad is using capture_actions to intercept ActionsBuf, ensuring typed actions emitted via cx.action are properly caught and processed by parents.

To map Makepad lifecycle and drawing events to defined actions, implement handle_event in your widget to process Event enums and Hit matching, then emit corresponding actions using the ActionTrait API.

Makepad widget actions might not reach parent components if they are not emitted using cx.action or if parents fail to intercept the ActionsBuf flow using capture_actions during event handling.
