Struct Responsive

pub struct Responsive<'a, Message, Theme = Theme, Renderer = Renderer<Renderer, Renderer>> { /* private fields */ }

Available on crate feature lazy only.

A widget that is aware of its dimensions.

A Responsive widget will always try to fill all the available space of its parent.

Implementations

impl<'a, Message, Theme, Renderer> Responsive<'a, Message, Theme, Renderer>

where Renderer: Renderer,

pub fn new( view: impl Fn(Size) -> Element<'a, Message, Theme, Renderer> + 'a, ) -> Responsive<'a, Message, Theme, Renderer>

Creates a new Responsive widget with a closure that produces its contents.

The view closure will be provided with the current Size of the Responsive widget and, therefore, can be used to build the contents of the widget in a responsive way.

Trait Implementations

impl<'a, Message, Theme, Renderer> From<Responsive<'a, Message, Theme, Renderer>> for Element<'a, Message, Theme, Renderer>

where Message: 'a, Theme: 'a, Renderer: Renderer + 'a,

fn from( responsive: Responsive<'a, Message, Theme, Renderer>, ) -> Element<'a, Message, Theme, Renderer>

Converts to this type from the input type.

impl<'a, Message, Theme, Renderer> Widget<Message, Theme, Renderer> for Responsive<'a, Message, Theme, Renderer>

where Renderer: Renderer,

fn size(&self) -> Size<Length>

Returns the Size of the Widget in lengths.

fn layout( &self, _tree: &mut Tree, _renderer: &Renderer, limits: &Limits, ) -> Node

Returns the layout::Node of the Widget.

fn operate( &self, tree: &mut Tree, layout: Layout<'_>, renderer: &Renderer, operation: &mut dyn Operation, )

fn overlay<'b>( &'b mut self, tree: &'b mut Tree, layout: Layout<'_>, renderer: &Renderer, translation: Vector, ) -> Option<Element<'b, Message, Theme, Renderer>>

Returns the overlay of the Widget, if there is any.

fn size_hint(&self) -> Size<Length>

Returns a Size hint for laying out the Widget.

fn children(&self) -> Vec<Tree>

Returns the state Tree of the children of the Widget.

fn diff(&self, _tree: &mut Tree)

Reconciles the Widget with the provided Tree.
