gtk:widget-accessible (widget)

widget -- a gtk:widget object

The AtkObject associated with widget.

Returns the accessible object that describes the widget to an assistive technology. If accessibility support is not available, this AtkObject instance may be a no-op. Likewise, if no class-specific AtkObject implementation is available for the widget instance in question, it will inherit an AtkObject implementation from the first ancestor class for which such an implementation is defined.

The documentation of the ATK library contains more information about accessible objects and their uses.
