Implementations§

Source§

impl<D> SelectState<D>
where D: SelectDelegate + 'static,

Source

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

Create a new Select state.

Source

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

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

When true, there will be a search input at the top of the dropdown menu.

Source

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.

Source

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

Set selected value for the select.

This method will to get position from delegate and set selected index.

If the value is not found, the None will be sets.

Source

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

Set the items for the select state.

Source

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

Get the selected index of the select.

Source

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

Get the selected value of the select.

Source

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

Focus the select input.
