Struct SelectionList 

pub struct SelectionList<'a, T, Message, Theme = Theme, Renderer = Renderer>
where
    T: Clone + ToString + Eq + Hash,
    [T]: ToOwned<Owned = Vec<T>>,
    Renderer: Renderer + Renderer<Font = Font>,
    Theme: Catalog + Catalog,
{ /* private fields */ }

A widget for selecting a single value from a dynamic scrollable list of options.

Implementations

impl<'a, T, Message, Theme, Renderer> SelectionList<'a, T, Message, Theme, Renderer>

where Message: 'a + Clone, Renderer: 'a + Renderer + Renderer<Font = Font>, Theme: 'a + Catalog + Catalog + Catalog, T: Clone + Display + Eq + Hash, [T]: ToOwned<Owned = Vec<T>>,

pub fn new( options: &'a [T], on_selected: impl Fn(usize, T) -> Message + 'static, ) -> Self

Creates a new SelectionList with the given list of options, the current selected value, and the message to produce when an option is selected. This will default the style, text_size and padding. use new_with to set those.

pub fn new_with( options: &'a [T], on_selected: impl Fn(usize, T) -> Message + 'static, text_size: f32, padding: impl Into<Padding>, style: impl Fn(&Theme, Status) -> Style + 'a + Clone, selected: Option<usize>, font: Font, ) -> Self

where <Theme as Catalog>::Class<'a>: From<StyleFn<'a, Theme, Style>>,

Creates a new SelectionList with the given list of options, the current selected value, the message to produce when an option is selected, the style, text_size, padding and font.

pub fn width(self, width: impl Into<Length>) -> Self

Sets the width of the SelectionList.

pub fn height(self, height: impl Into<Length>) -> Self

Sets the height of the SelectionList.

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

where <Theme as Catalog>::Class<'a>: From<StyleFn<'a, Theme, Style>>,

Sets the style of the SelectionList.

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

Sets the class of the input of the SelectionList.

Trait Implementations

impl<'a, T, Message, Theme, Renderer> From<SelectionList<'a, T, Message, Theme, Renderer>> for Element<'a, Message, Theme, Renderer>

where T: Clone + ToString + Eq + Hash + Display, Message: 'static, Renderer: 'a + Renderer + Renderer<Font = Font>, Theme: 'a + Catalog + Catalog,

fn from(selection_list: SelectionList<'a, T, Message, Theme, Renderer>) -> Self

Converts to this type from the input type.

impl<'a, T, Message, Theme, Renderer> Widget<Message, Theme, Renderer> for SelectionList<'a, T, Message, Theme, Renderer>

where T: 'a + Clone + ToString + Eq + Hash + Display, Message: 'static, Renderer: Renderer + Renderer<Font = Font> + 'a, Theme: Catalog + Catalog,

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 tag(&self) -> Tag

Returns the Tag of the Widget.

fn state(&self) -> State

Returns the State of 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, state: &mut Tree, event: &Event, layout: Layout<'_>, cursor: Cursor, renderer: &Renderer, clipboard: &mut dyn Clipboard, shell: &mut Shell<'_, Message>, viewport: &Rectangle, )

Processes a runtime Event.

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

Returns the current mouse::Interaction of the Widget.

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

Draws the Widget using the associated Renderer.

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

Returns a Size hint for laying out 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, _tree: &'a mut Tree, _layout: Layout<'a>, _renderer: &Renderer, _viewport: &Rectangle, _translation: Vector, ) -> Option<Element<'a, Message, Theme, Renderer>>
