## Description

The Accessible interface provides for a hierarchical tree of accessible objects corresponding to user interface components and content in an accessible application. Accessible objects provide name, descriptive information, state information, and information on the "role" of the object in the user interface. The capabilities of these objects may be queried via interface queries, as they are implemented via interface aggregation. These objects are located in a containment hierarchy with parent/child relationships, and may have other functional relationships to objects within the tree.

## Details

### struct Accessible

    struct Accessible {
    	CORBA_Object objref;
    	/* And some other bits */
    	guint        on_loan : 1;
