This method of the IAccessibleDefault Interface retrieves the child object that currently has the keyboard focus. If the object itself has the keyboard focus, this method returns zero as a VT_14 type. If a child has the focus but isn't an accessible object, it returns the child ID as a VT_14 type. If a child has the focus and is an accessible object, this method returns its IDispatch interface.
public Variant getAccFocus();
Returns the Variant object that contains information about the retrieved child object.
