Struct Select 

pub struct Select { /* private fields */ }

Picks one option from a list, shown in a field-like trigger. Enter, Space or an arrow key opens the list with the current option focused; arrows move, Enter picks, Escape closes, and focus returns to the field.

Implementations

impl Select

pub fn new( selected: Binding<usize>, options: impl IntoIterator<Item = impl Into<String>>, ) -> Self

A select over options; selected holds the zero-based index of the choice.

pub fn of<T: Clone + PartialEq + 'static>( value: Binding<T>, options: impl IntoIterator<Item = (T, impl Into<String>)>, ) -> Self

A select over values of any type, each with the text that shows it: value holds the value itself, not its position. A value that is not among the options shows nothing until one is picked.

use ravenrs_reactive::State;
use ravenrs_widgets::{Select, Ui};

#[derive(Clone, PartialEq)]
enum Quality {
    Draft,
    Final,
}

let quality = State::new(Quality::Final);
let select = Select::of(quality.binding(), [(Quality::Draft, "Draft"), (Quality::Final, "Final")]);
let mut ui = Ui::new(select, ravenrs_style::Theme::raven_dark());
ui.update();

pub fn searchable(self) -> Self

Opens with a search box that filters the options as you type.

pub fn size(self, size: ButtonSize) -> Self

Sets the height and text size to line up with a Button of the same size (Medium by default).

pub fn fill(self) -> Self

Takes the width of its parent, as other fields of a form do.

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

Sets the width in logical pixels (220 by default).

pub fn label(self, label: impl Into<String>) -> Self

The name screen readers announce, such as “Country”. Inside a crate::FormField, its label is used instead.

pub fn disabled(self, disabled: bool) -> Self

Turns the control off: it fades, leaves the tab order and ignores input.

pub fn read_only(self, read_only: bool) -> Self

Shows the value without letting it change; it can still be focused and read.
