pub fn window_buttons(ui: &mut Ui<'_>)Expand description
The minimize/maximize/close cluster. Renders nothing when the OS already
provides controls (native decorations, or macOS traffic lights), so it
is always safe to call. It grows to the height it is given — the
strip’s, in titlebar_with — and is a titlebar tall where nothing
gives it one, since a grow child adds nothing to a fit parent’s
height.
