Expand description

The text edit state stored between frames.

Attention: You also need to store the updated state.

let mut output = TextEdit::singleline(&mut text).show(ui);

// Create a new selection range
let min = CCursor::new(0);
let max = CCursor::new(0);
let new_range = CCursorRange::two(min, max);

// Update the state
output.state.set_ccursor_range(Some(new_range));
// Store the updated state
output.state.store(ui.ctx(), output.response.id);

Fields§

§cursor_range: Option<CursorRange>§ccursor_range: Option<CCursorRange>

This is what is easiest to work with when editing text, so users are more likely to read/write this.

§undoer: Arc<Mutex<Undoer<(CCursorRange, String)>>>

Wrapped in Arc for cheaper clones.

§has_ime: bool§singleline_offset: f32
