Struct Float 

pub struct Float<'a, Message, Theme = Theme, Renderer = Renderer>
where
    Theme: Catalog,
{ /* private fields */ }

A widget that can make its contents float over other widgets.

Implementations

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

where Theme: Catalog,

pub fn new(content: impl Into<Element<'a, Message, Theme, Renderer>>) -> Self

Creates a new Float widget with the given content.

pub fn scale(self, scale: f32) -> Self

Sets the scale to be applied to the contents of the Float.

pub fn translate( self, translate: impl Fn(Rectangle, Rectangle) -> Vector + 'a, ) -> Self

Sets the translation logic to be applied to the contents of the Float.

The logic takes the original (non-scaled) bounds of the contents and the viewport bounds. These bounds can be useful to ensure the floating elements always stay on screen.

pub fn style(self, style: impl Fn(&Theme) -> Style + 'a) -> Self

where Theme::Class<'a>: From<StyleFn<'a, Theme>>,

Sets the style of the Float.

pub fn class(self, class: impl Into<Theme::Class<'a>>) -> Self

Available on crate feature advanced only.

Sets the style class of the Float.

Trait Implementations

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

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

fn from(float: Float<'a, Message, Theme, Renderer>) -> Self

Converts to this type from the input type.

impl<Message, Theme, Renderer> Widget<Message, Theme, Renderer> for Float<'_, Message, Theme, Renderer>

where Theme: Catalog, Renderer: Renderer,

fn tag(&self) -> Tag

Returns the Tag of the Widget.

fn state(&self) -> State

Returns the State of 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.

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

Returns the Size of the Widget in lengths.

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

Returns a Size hint for laying out the Widget.

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

Returns the layout::Node of the Widget.

fn update( &mut self, tree: &mut Tree, event: &Event, layout: Layout<'_>, cursor: Cursor, renderer: &Renderer, shell: &mut Shell<'_, Message>, viewport: &Rectangle, )

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

Applies an Operation to the Widget.

fn overlay<'a>( &'a mut self, state: &'a mut Tree, layout: Layout<'a>, renderer: &Renderer, viewport: &Rectangle, offset: Vector, ) -> Option<Element<'a, Message, Theme, Renderer>>

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