Implementations

impl TextInput

pub fn new(initial: &str, max_len: usize) -> Self

pub fn value(&self) -> String

pub fn is_empty(&self) -> bool

pub fn cursor(&self) -> usize

pub fn len(&self) -> usize

pub fn slice(&self, start: usize, end: usize) -> String

pub fn clear_selection(&mut self)

pub fn has_selection(&self) -> bool

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

Inclusive start and exclusive end of the selection, if any.

pub fn selected_text(&self) -> Option<String>

pub fn delete_selection(&mut self) -> bool

Removes the selected range. Returns true when something was deleted.

pub fn select_word(&mut self)

Select the word under (or beside) the cursor — macOS Select Word.

pub fn set_cursor(&mut self, cursor: usize)

pub fn set_cursor_from_col(&mut self, col: usize)

Places the cursor at a display column of the visible window, as produced by TextInput::visible. Past the end of the text the cursor lands at the end.

pub fn at_start(&self) -> bool

pub fn at_end(&self) -> bool

pub fn split_off_at_cursor(&mut self) -> Self

Cuts everything after the cursor into a new input.

pub fn append(&mut self, other: &Self) -> bool

Appends another input’s text, leaving the cursor at the join. Returns false without changing either input when the full join would exceed this field’s grapheme or byte limit.

pub fn insert(&mut self, c: char)

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

Inserts a run of text at the cursor. Tab/newline separators are flattened, while terminal control bytes are discarded at the input boundary so they can never reach the renderer.

pub fn backspace(&mut self)

pub fn delete(&mut self)

pub fn delete_to_start(&mut self)

pub fn delete_to_end(&mut self)

pub fn delete_word_left(&mut self)

pub fn left(&mut self)

pub fn right(&mut self)

pub fn select_left(&mut self)

pub fn select_right(&mut self)

pub fn word_left(&mut self)

pub fn word_right(&mut self)

pub fn select_word_left(&mut self)

pub fn select_word_right(&mut self)

pub fn home(&mut self)

pub fn end(&mut self)

pub fn select_home(&mut self)

pub fn select_end(&mut self)

pub fn word_left_index(&self) -> usize

Where the caret lands moving one word left; the body editor uses this to extend a selection across block boundaries.

pub fn word_right_index(&self) -> usize

Where the caret lands moving one word right.

pub fn wrap_breaks(&self, width: usize) -> Vec<(usize, usize)>

Soft-wrap into visual rows of at most width columns. Prefers breaking after whitespace; hard-breaks when a single word is wider than the field. Empty text yields one empty row.

pub fn wrap_height(&self, width: usize) -> usize

How many visual rows the text needs at width (at least 1).

pub fn wrap_cursor_from_breaks(&self, breaks: &[(usize, usize)]) -> (usize, u16)

Cursor as (visual_row, column) from precomputed wrap breaks.

pub fn wrap_cursor(&self, width: usize) -> (usize, u16)

Cursor as (visual_row, column) for a wrapped layout.

pub fn set_cursor_from_wrap(&mut self, width: usize, row: usize, col: usize)

Place the caret from a click on a wrapped row.

pub fn wrap_up(&mut self, width: usize, prefer_col: u16) -> bool

Move the caret up one visual row. Returns false when already on the first row (caller may leave the block).

pub fn wrap_down(&mut self, width: usize, prefer_col: u16) -> bool

Move the caret down one visual row. Returns false when already on the last row (caller may leave the block).

pub fn wrapped(&self, width: usize) -> WrappedView

Full soft-wrapped view for painting a multi-line field.

pub fn wrapped_with_sel( &self, width: usize, sel: Option<(usize, usize)>, ) -> WrappedView

Like Self::wrapped, but uses an explicit grapheme-range selection (for body-level multi-line selections).

pub fn wrapped_from_breaks( &self, breaks: &[(usize, usize)], sel: Option<(usize, usize)>, ) -> WrappedView

Soft-wrapped view from precomputed breaks (one wrap pass per paint).

pub fn place_cursor(&mut self, cursor: usize)

Move the caret and drop this line’s own selection: when the body editor drives the caret, the multi-line selection is its to own.

pub fn visible(&mut self, width: usize) -> View

Text to draw in a field width columns wide, the cursor’s column within that field, and the selection’s column span when it overlaps. Single-row fields (title, status) use this; body uses Self::wrapped.
