Struct Listbox 

pub struct Listbox(/* private fields */);

Available on crate feature listbox only.

A Listbox struct that encapsulates a list of strings, allowing for navigation and manipulation through a cursor. It supports basic operations such as moving the cursor forward and backward, retrieving the current item, and initializing from an iterator of displayable items.

Implementations

impl Listbox

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn push_string(&mut self, item: String)

pub fn from_styled_graphemes(items: Vec<StyledGraphemes>) -> Self

Creates a new Listbox from a vector of StyledGraphemes.

pub fn items(&self) -> &Vec<StyledGraphemes>

Returns a reference to the vector of items in the listbox.

pub fn position(&self) -> usize

Returns the current position of the cursor within the listbox.

pub fn get(&self) -> StyledGraphemes

Retrieves the item at the current cursor position as a String. If the cursor is at a position without an item, returns an empty String.

pub fn backward(&mut self) -> bool

Moves the cursor backward in the listbox, if possible. Returns true if the cursor was successfully moved backward, false otherwise.

pub fn forward(&mut self) -> bool

Moves the cursor forward in the listbox, if possible. Returns true if the cursor was successfully moved forward, false otherwise.

pub fn move_to_head(&mut self)

Moves the cursor to the head (beginning) of the listbox.

pub fn move_to_tail(&mut self)

Moves the cursor to the tail of the listbox.

pub fn is_tail(&self) -> bool
