TextInputState

Struct TextInputState 

Source
pub struct TextInputState {
    pub text: String,
    pub cursor_pos: usize,
    pub selection_anchor: Option<usize>,
    pub focused: bool,
    pub caret_visible: bool,
    pub last_edit_time: f32,
}
Expand description

Text input state managed by the renderer.

Components don’t store this directly — the renderer maintains it and components query/modify it through the Renderer trait methods.

Fields§

§text: String

The full text content.

§cursor_pos: usize

Cursor position as byte offset into the text.

§selection_anchor: Option<usize>

Selection anchor. If Some, the selection is from anchor to cursor. If None, there is no selection.

§focused: bool

Whether the input is focused (shows cursor, accepts keyboard).

§caret_visible: bool

Whether the caret is currently visible (for blinking).

§last_edit_time: f32

Last edit timestamp for undo coalescing.

Implementations§

Source§

impl TextInputState

Source

pub fn new(text: impl Into<String>) -> Self

Create a new TextInputState with the given initial text.

Source

pub fn selection_range(&self) -> Option<(usize, usize)>

Get the selection range as (start, end) byte offsets. Returns None if there is no selection.

Source

pub fn selected_text(&self) -> String

Get the selected text, or empty string if no selection.

Source

pub fn insert(&mut self, new_text: &str)

Insert text at the current cursor position, replacing any selection.

Source

pub fn delete(&mut self, backward: bool, count: usize) -> String

Delete characters. If there’s a selection, delete it. Otherwise delete count characters backward (backspace) or forward (delete).

Source

pub fn move_cursor(&mut self, direction: TextDirection, extend_selection: bool)

Move the cursor in the given direction.

Source

pub fn select_all(&mut self)

Select all text.

Source

pub fn cursor_byte_pos(&self) -> usize

Get the byte offset of the cursor.
