Struct List 

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

}

The Private List Handles the Actual list rendering.

on_selected: Box<dyn Fn(usize, T) -> Message>

Function Pointer On Select to call on Mouse button press.

padding: Padding

The padding Width

text_size: f32

The Text Size

selected: Option<usize>

Set the Selected ID manually.

phantomdata: PhantomData<Renderer>

Shadow Type holder for Renderer.

Trait Implementations

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

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

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