gtk:info-bar-show-close-button (object)

object -- a gtk:info-bar widget
setting -- true to include a Close button

The accessor for the show-close-button slot gets or sets whether to include a standard Close button. If true, a standard Close button is shown. When clicked it emits the :close response. The gtk:info-bar implementation is deprecated since 4.10. Do not use it in newly written code.
