Trait Implementations

impl<'v> Builder<'v> for Constrain

type View = Constrain

impl Clone for Constrain

fn clone(&self) -> Constrain

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Constrain

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl View for Constrain

type Args<'v> = Constrain

Arguments for building a view.

type Response = ()

Response from this view that is given to the user

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

Create your view with the args provided from the user

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

Lay out your view.

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

Update your view with the args provided from the user

fn flex(&self) -> Flex

If your view can be flexible, this returns how flexible it is.

fn interests(&self) -> Interest

If you want to receive events, you need to provide some Interests

fn primary_axis(&self) -> Axis

The primary axis of your view.

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

When you provide specific Interest and an event is processed by the runtime, this method is called.

fn size(&self, intrinsic: IntrinsicSize<'_>, axis: Axis, extent: f32) -> f32

This is a hint can be used for determining how much space a view will take up on a specific axis with a specific extent (width/height).

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

The default layout handling behavior to delegate to your children.

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

The default draw handling behavior to delegate to your children.
