Module textarea 

A multi-line editable text control.

TextArea is a view rather than a RenderOnce builder, for the same reason crate::controls::input::TextInput is: the caret, the selection, the in-progress input method composition, and the vertical scroll position all outlive a frame. Text wraps at the width the control was given, so there is no horizontal scrolling, and the caret moves by visual line.

let notes = cx.new(|cx| {
    TextArea::new("review.notes", window, cx)
        .placeholder("What changed, and why")
        .rows(4)
        .max_rows(12)
});
cx.subscribe(&notes, |_host, notes, event, cx| {
    if let TextAreaEvent::Submit = event {
        let _typed = notes.read(cx).value().to_string();
    }
})
.detach();

Constants

KEY_CONTEXT

The key context every text area publishes, so a host can layer its own bindings on top without re-declaring these.
