Non-text objects can have either a + single link or a collection of links such as when the non-text object is + an image map. + + Linked objects and anchors are implementation dependent. This interface is derived + from IAccessibleAction. IAccessibleAction::nActions is one greater than the + maximum value for the indices used with the methods of this interface. + + Furthermore, the object that implements this interface has to be connected + implicitly or explicitly with an object that implements IAccessibleText. + IAccessibleHyperlink::startIndex and IAccessibleHyperlink::endIndex are + indices with respect to the text exposed by IAccessibleText. + + This interface provides access to a single object which can have multiple actions. + An example is an image map which is an image with multiple links each of which is + associated with a separate non-overlapping area of the image. This interface could + also be applied to other kinds of objects with multiple actions such as "smart tags" + which are objects, typically strings, which have multiple actions such as + "Activate URI", "Bookmark URI", etc. + + An interesting use case is an image map where each area is associated with multiple + actions, e.g. an image map of smart tags. In this case you would have to implement + two levels of accessible hyperlinks. The first level hyperlinks would only implement + anchor and anchorTarget. The anchors would all reference the image object. The + anchorTargets would reference the second level accessible hyperlink objects. None + of the IAccessibleAction methods would be implemented on the first level hyperlink + objects. The second level hyperlink objects would implement the IAccessibleAction + methods. Their anchors would also reference the image object and their anchorTargets + would reference URLs or the objects that would be activated. + + This use case demonstrates that in some cases there is no need for IAccessibleHyperlink + to derive from IAccessibleAction. As a result it may be removed in a later version of + the IDL and it is suggested that implementations should not rely on the inheritance. + +*/ +[object, uuid(01C20F2B-3DD2-400f-949F-AD00BDAB1D41)] +interface IAccessibleHyperlink : IAccessibleAction +{ + + /** @brief Returns an object that represents the link anchor, as appropriate + for the link at the specified index. + @param [in] index + A 0 based index identifies the anchor when, as in the case of an image map, + there is more than one link represented by this object.
