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

A generic Overlay.

Implementations

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

where Renderer: Renderer,

pub fn new(overlay: Box<dyn Overlay<Message, Theme, Renderer> + 'a>) -> Self

Creates a new Element containing the given Overlay.

pub fn map<B>( self, f: &'a dyn Fn(Message) -> B ) -> Element<'a, B, Theme, Renderer>

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

Applies a transformation to the produced message of the Element.

pub fn layout(&mut self, renderer: &Renderer, bounds: Size) -> Node

Computes the layout of the Element in the given bounds.

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

Processes a runtime Event.

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

Returns the current mouse::Interaction of the Element.

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

Draws the Element and its children using the given Layout.

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

Applies a widget::Operation to the Element.

pub fn is_over( &self, layout: Layout<'_>, renderer: &Renderer, cursor_position: Point ) -> bool

Returns true if the cursor is over the Element.

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

Returns the nested overlay of the Element, if there is any.

Trait Implementations

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

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

fn from(group: Group<'a, Message, Theme, Renderer>) -> Self
