Struct zng :: toggle :: Selector Copy item path

impl Selector

pub fn new(selector: impl SelectorImpl) -> Selector

New custom selector.

pub fn nil() -> Selector

Represents no selector and the inability to select any item.

pub fn single<T>(selection: impl IntoVar<T>) -> Selector
where T: VarValue,

Represents the “radio” selection of a single item.

pub fn single_opt<T>(selection: impl IntoVar<Option<T>>) -> Selector
where T: VarValue,

Represents the “radio” selection of a single item that is optional.

pub fn bitflags<T>(selection: impl IntoVar<T>) -> Selector
where T: VarValue + BitOr<Output = T> + BitAnd<Output = T> + Not<Output = T>,

Represents the “check list” selection of bitflags.

Add the selector subscriptions in WIDGET.

pub fn select(&self, value: Box<dyn AnyVarValue>) -> Result<(), SelectorError>

Insert the value in the selection, returns Ok(()) if the value was inserted or was already selected.

pub fn deselect( &self, value: &(dyn AnyVarValue + 'static), ) -> Result<(), SelectorError>

Remove the value from the selection, returns Ok(()) if the value was removed or was not selected.

pub fn is_selected(&self, value: &(dyn AnyVarValue + 'static)) -> bool

Returns true if the value is selected.
