Module edit 

Editable text: the retained state of every text_edit node, keyed by node Key, built on cosmic-text’s editor.

A view declares an editor with Ui::text_edit(label, initial, &opts, spec), where opts is an EditOptions. The core keeps the buffer, caret, selection, IME composition and undo history across frames, routes InputEvent::Text / InputEvent::Key to the focused editor and posts changed and submit events. An app reads the draft back with Core::edit_text / Ui::edit_text and replaces it with Core::set_edit_text; the store itself is not something an app touches.

use kui_core::{Core, EditOptions, InputEvent, NodeSpec, Size, TextStyle};

let mut core = Core::new();
let mut ui = core.frame(Size::new(400.0, 300.0), 1.0);
let opts = EditOptions {
    style: TextStyle::new(14.0),
    autofocus: true,
    ..Default::default()
};
let field = ui.text_edit("name", "hello", &opts, NodeSpec::row().grow_width().pad(4.0));
ui.finish();

// Typing reaches the focused editor; the host reads the draft back.
core.handle_input(InputEvent::Text(" world".into()));
assert_eq!(core.edit_text(field).as_deref(), Some("hello world"));

Structs

EditOptions

How a text_edit node behaves: its text style, whether it is a single-line field or a multiline document, and how it takes focus and paints its selection. Build one with struct update syntax from Default.

EditStore

The retained editors of one window, owned by Core. Reach it through Ui::text_edit, Core::edit_text and Core::set_edit_text rather than directly.

Constants

MAX_UNDECLARED_EDITS

How many undeclared editors the store keeps before the longest undeclared one is dropped. A declared editor is never evicted, however many there are: retention across absence is what text_edit promises, so this is a ceiling, not a prune. An editor holding a short line is a few KB and one holding a long line about 22 KB, so a full budget is a few MB.
