///
/// This is just a shortcut for `IdView::new(id, self)`
///
/// You can use the given id to find the view in the layout tree.
///
/// # Examples
///
/// ```rust
/// # use cursive::Cursive;
/// # use cursive::views::TextView;
/// # use cursive::view::Boxable;
/// use cursive::view::Identifiable;
///
/// let mut siv = Cursive::dummy();
/// siv.add_layer(
/// TextView::new("foo")
/// .with_id("text")
/// .fixed_width(10)
/// );
///
/// // You could call this from an event callback
/// siv.call_on_id("text", |view: &mut TextView| {
/// view.set_content("New content!");
/// });
/// ```
///
/// # Notes
///
/// You should call this directly on the view you want to retrieve later,
/// before other wrappers like [`fixed_width`]. Otherwise, you would be
/// retrieving a [`BoxView`]!
///
/// [`fixed_width`]: trait.Boxable.html#method.fixed_width
