public virtual unowned Object get_accessible ()
Returns the accessible object that describes the widget to an assistive technology.
If accessibility support is not available, this Object instance may be a no-op. Likewise, if no class-specific Object implementation is available for the widget instance in question, it will inherit an Object 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.
