Struct vizia::views::List

pub struct List { /* private fields */ }

A view for creating a list of items from a binding to a Vec<T>

Implementations

impl List

pub fn new<L, T>( cx: &mut Context, list: L, item_content: impl Fn(&mut Context, usize, MapRef<L, T>) + 'static, ) -> Handle<'_, List>

where L: Lens, T: 'static, <L as Lens>::Target: Deref<Target = [T]>,

pub fn new_generic<L, T>( cx: &mut Context, list: L, list_len: impl Fn(&<L as Lens>::Target) -> usize + 'static, list_index: impl Copy + Fn(&<L as Lens>::Target, usize) -> &T + 'static, item_content: impl Fn(&mut Context, usize, MapRef<L, T>) + 'static, ) -> Handle<'_, List>

where L: Lens, T: 'static,

Creates a new List view with a binding to the given lens and a template for constructing the list items

Trait Implementations

impl View for List

fn element(&self) -> Option<&'static str>

Specifies a name for the view type which can be used as an element selector in css.

fn build<F>(self, cx: &mut Context, content: F) -> Handle<'_, Self>

where F: FnOnce(&mut Context),

Builds the view into the tree and returns a handle which can be used to apply style and layout modifiers to the view.

fn event(&mut self, cx: &mut EventContext<'_>, event: &mut Event)

Handles any events received by the view.

fn draw(&self, cx: &mut DrawContext<'_>, canvas: &Canvas)

Provides custom drawing for the view.

fn accessibility(&self, cx: &mut AccessContext<'_>, node: &mut AccessNode)
