Enum Handled 

pub enum Handled {
    No,
    Yes,
}

Whether an event was consumed.

Variants

No

The widget ignored the event.

Yes

The widget acted on the event.

This also marks the node dirty. A widget that consumes an event has almost always changed what it draws, and the cost of being wrong is repainting one widget-sized rectangle. Missing an invalidation costs a stale frame that only shows up on hardware, so the default errs the cheap way. Use EventCtx::invalidate for the rare change that consumes nothing.
