pub struct SelectState<D: SearchableListDelegate + 'static>
where
    <D::Item as SearchableListItem>::Value: PartialEq + Clone,
{ /* private fields */ }

State of the Select component.

Implementations

impl<D> SelectState<D>

where D: SearchableListDelegate + 'static, <D::Item as SearchableListItem>::Value: PartialEq + Clone,

pub fn new( delegate: D, selected_index: Option<IndexPath>, window: &mut Window, cx: &mut Context<'_, Self>, ) -> Self

Create a new Select state.

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

Sets whether the dropdown menu is searchable, default is false.

When true, a search input appears at the top of the dropdown menu.

pub fn set_selected_index( &mut self, selected_index: Option<IndexPath>, window: &mut Window, cx: &mut Context<'_, Self>, )

Set the selected index for the select.

pub fn set_selected_value( &mut self, selected_value: &<D::Item as SearchableListItem>::Value, window: &mut Window, cx: &mut Context<'_, Self>, )

Set selected value for the select.

Looks up the position from the delegate and sets the selected index accordingly. Passes None when the value is not found.

The delegate looks the value up in its matched items, so an active search query is cleared first to get an index into the full item list.

pub fn set_items( &mut self, items: D, _: &mut Window, cx: &mut Context<'_, Self>, )

where D: SearchableListDelegate + 'static,

Replace the delegate (item data) for the select state.

pub fn selected_index(&self, cx: &App) -> Option<IndexPath>

Get the current selected index.

pub fn selected_value(&self) -> Option<&<D::Item as SearchableListItem>::Value>

Get the current selected value.

pub fn focus(&self, window: &mut Window, cx: &mut App)

Focus the select trigger input.
