Struct meli::components::utilities::Selector

pub struct Selector<T: 'static + PartialEq + Debug + Clone + Sync + Send, F: 'static + Sync + Send> {
    single_only: bool,
    entries: Vec<(T, bool)>,
    pub content: CellBuffer,
    theme_default: ThemeAttribute,
    cursor: SelectorCursor,
    vertical_alignment: Alignment,

}

Shows a little window with options for user to select.

Instantiate with Selector::new(). Set single_only to true if user should only choose one of the options. After passing input events to this component, check Selector::is_done to see if the user has finalised their choices. Collect the choices by consuming the Selector with Selector::collect()

Fields

single_only: bool

allow only one selection

entries: Vec<(T, bool)>

content: CellBuffer

theme_default: ThemeAttribute

cursor: SelectorCursor

vertical_alignment: Alignment

horizontal_alignment: Alignment

title: String

done: bool

If true, user has finished their selection

done_fn: F

dirty: bool

id: ComponentId
