Returns the “default value” for a type.

impl View for KeyArea

type Args<'v> = KeyArea

Arguments for building a view.

type Response = KeyAreaResponse

Response from this view that is given to the user

fn create(args: Self::Args<'_>) -> Self

Create your view with the args provided from the user

fn update(&mut self, _args: Self::Args<'_>, _ui: &Ui<'_>) -> Self::Response

fn layout(&mut self, layout: Layout<'_>, space: Space) -> Size

Lay out your view.

fn draw(&mut self, render: Render<'_, '_>)

Draw your view

fn default_event(&mut self, event: ViewEvent, ctx: EventCtx<'_>) -> Handled

The default event handling behavior to delegate to your children.

fn default_layout(&mut self, layout: Layout<'_>, space: Space) -> Size
