Widget.getAccessible

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

library contains more information about accessible objects and their uses.
