gtk:widget-error-bell (widget)

widget -- a gtk:widget object

Notifies the user about an input-related error on this widget. If the gtk-error-bell setting is true, it calls the gdk:surface-beep function, otherwise it does nothing.

Note that the effect of the gdk:surface-beep function can be configured in many ways, depending on the windowing backend and the desktop environment or window manager that is used.
