/** @brief This interface represents hyperlinks.
|
|
|
|
This interface represents a hyperlink associated with a single substring
|
|
of text or single non-text object. 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 indicates 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 is an implementation dependent value. For example, for a text link this

method could return the substring of the containing string where the subsgtring

is overridden with link behavior, and for an image link this method could return

an IUnknown VARIANT for IAccessibleImage.
