The accessor for the gtk-shell-shows-menubar slot of the gtk:settings class gets or sets whether the desktop environment is displaying the menubar. Set to true if the desktop environment is displaying the menubar, false if the application should display it itself. This property is deprecated since 4.20. This setting is not relevant anymore.
