Struct Responsive

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

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 tag(&self) -> Tag

Returns the Tag of the Widget.

fn state(&self) -> State

Returns the State of the Widget.

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, )

Applies an Operation to the Widget.

fn on_event( &mut self, tree: &mut Tree, event: Event, layout: Layout<'_>, cursor: Cursor, renderer: &Renderer, clipboard: &mut dyn Clipboard, shell: &mut Shell<'_, Message>, viewport: &Rectangle, ) -> Status

Processes a runtime Event.

fn draw( &self, tree: &Tree, renderer: &mut Renderer, theme: &Theme, style: &Style, layout: Layout<'_>, cursor: Cursor, viewport: &Rectangle, )

Draws the Widget using the associated Renderer.

fn mouse_interaction( &self, tree: &Tree, layout: Layout<'_>, cursor: Cursor, viewport: &Rectangle, renderer: &Renderer, ) -> Interaction

Returns the current mouse::Interaction of the Widget.

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

fn id(&self) -> Option<Id>

Returns the id of the widget

fn set_id(&mut self, _id: Id)

fn drag_destinations( &self, state: &Tree, layout: Layout<'_>, renderer: &Renderer, dnd_rectangles: &mut DndDestinationRectangles, )

Adds the drag destination rectangles of the widget. Runs after the layout phase for each widget in the tree.

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(&mut self, _tree: &mut Tree)

Reconciliates the Widget with the provided Tree.
