[propget] HRESULT localizedRelationType([out] BSTR localizedRelationType );
[propget] HRESULT nTargets([out] long nTargets );
[propget] HRESULT relationType([out] BSTR relationType );
[propget] HRESULT target([in] long targetIndex, [out] IUnknown target );
[propget] HRESULT targets([in] long maxTargets, [out, size_is(maxTargets), length_is( nTargets)] IUnknown targets, [out] long nTargets );

Methods

localizedRelationType()

Returns a localized version of the relation type.

[propget] HRESULT localizedRelationType(
  [out] BSTR localizedRelationType
);
Parameters
localizedRelationType
Return value

S_OK.

nTargets()

Returns the number of targets() for this relation.

[propget] HRESULT nTargets(
  [out] long nTargets
);
Parameters
nTargets
Return value

S_OK.

relationType()

Returns the type of the relation.

[propget] HRESULT relationType(
  [out] BSTR relationType
);
Parameters
relationType
The strings returned are defined @ref grpRelations "in this section of the documentation".
Return value

S_OK.

target()

Returns one accessible relation target.

[propget] HRESULT target(
  [in] long targetIndex,
  [out] IUnknown target
);
Parameters
targetIndex
0 based index.
target
Return value

E_INVALIDARG if bad [in] passed, [out] value is null. S_FALSE if there is nothing to return, [out] value is null. S_OK.

targets()

Returns multiple accessible relation targets.

[propget] HRESULT targets(
  [in] long maxTargets,
  [out, size_is(maxTargets), length_is( nTargets)] IUnknown targets,
  [out] long nTargets
);
Parameters
maxTargets
Maximum size of the array allocated by the client.
targets
The array of target objects. Note that this array is to be allocated by the client and freed when no longer needed. Refer to @ref _arrayConsideration "Special Consideration when using Arrays" for more details. You will need to use QueryInterface on the IUnknown to get the IAccessible2.
nTargets
Actual number of targets in the returned array (not more than maxTargets)
Return value

S_FALSE if there is nothing to return, nTargets() is set to 0. S_OK.
