Implementations

impl TextFieldState

pub fn new() -> Self

pub fn insert_text(&mut self, text: &str)

pub fn delete_backward(&mut self)

pub fn delete_forward(&mut self)

pub fn move_cursor(&mut self, delta: isize, extend_selection: bool)

pub fn selected_text(&self) -> String

pub fn set_composition(&mut self, text: String, cursor: Option<(usize, usize)>)

pub fn commit_composition(&mut self, text: String)

pub fn cancel_composition(&mut self)

pub fn delete_surrounding(&mut self, before_bytes: usize, after_bytes: usize)

pub fn begin_drag(&mut self, idx_byte: usize, extend: bool)

pub fn drag_to(&mut self, idx_byte: usize)

pub fn end_drag(&mut self)

pub fn caret_index(&self) -> usize

pub fn ensure_caret_visible( &mut self, caret_x_px: f32, inner_width_px: f32, inset_px: f32, )

Keep caret visible inside inner content width (px). inset_px is a small padding (px) to avoid hugging edges.

pub fn ensure_caret_visible_xy( &mut self, caret_x_px: f32, caret_y_px: f32, inner_w_px: f32, inner_h_px: f32, inset_px: f32, )

Keep caret visible inside an inner rect (for multiline).

pub fn clamp_scroll(&mut self, content_h_px: f32)

pub fn reset_caret_blink(&mut self)

pub fn caret_visible(&self) -> bool

pub fn set_inner_width(&mut self, w_px: f32)

pub fn set_inner_height(&mut self, h_px: f32)

fn clone(&self) -> TextFieldState

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TextFieldState

fn fmt(&self, f: &mut Formatter<'_>) -> Result
