Struct ComboState

pub struct ComboState {
    pub query: String,
    pub is_open: bool,
    pub selected: Vec<usize>,
}

Application-owned state for a Combo.

Lives on the app struct and is mutated from update(). The widget reads it once per frame to render the trigger and popup; nothing inside ltk keeps a copy.

Fields

query: String

Current text in the trigger’s search field. Drives item filtering. Empty string means “no filter — show every item”.

is_open: bool

true when the popup is visible.

selected: Vec<usize>

Indices into the items slice currently selected. In single-select mode this is empty or has a single entry; in multi-select mode it can hold any subset.

Implementations

Convenience: toggle is_open.

pub fn select(&mut self, idx: usize)

Convenience: add idx to selected if not present.

pub fn unselect(&mut self, idx: usize)

Convenience: remove idx from selected if present.
