1020 @section _errors Error Handling

1021 HRESULT values are defined by the Microsoft® Win32® API. For more inf ormation, refer to

1022 <a href="http://msdn2.microsoft.com/en-us/library/bb401631.aspx">Interpreting HRESULT Values</a>

1023 in MSDN®.

1024

1025 Note that the S_FALSE return value is considered a non-error value and the

1026 SUCCEEDED macro will return TRUE. S_FALSE is used when there is no failure

1027 but there was nothing valid to return, e.g. in IAccessible2::attributes when

1028 there are no attributes. When S_FALSE is returned [out] pointer types should

1029 be NULL and [out] longs should generally be 0, but sometimes -1 is used such

1030 as IAccessible2::indexInParent, IAccessibleText::caretOffset, and

1031 IAccessibleHypertext::hyperlinkIndex.

1032

1033 Note that for BSTR [out] variables common COM practice is that the server does

1034 the SysAllocString and the client does the SysFreeString. Also note that when

1035 NULL is returned there is no need for the client to call SysFreeString. Pleas e

1036 refer to the documentation for each method for more details regarding error ha ndling.

1037

1038 @section _memory Memory Management

1039 The following memory management issues should be considered:

1040 @li Although [out] BSTR variables are declared by the client, their space is

1041 allocated by the server. They need to be freed with SysFreeString by the

1042 client at end of life; the same is true when BSTRs are used in structs or

1043 arrays which are passed to the server.

1044 @li If there is no valid [out] BSTR to return, the server should return S_FALS E and

1045 assign NULL to the output, e.g. *theOutBSTR = NULL;.

1046 @li COM interfaces need to be referenced with AddRef when used and dereference d

1047 with Release at end of life.

1048 @li Single [out] longs, HWNDs, booleans, and structs are declared by the calle r

1049 and passed by reference. The marshaller does all the memory management.

1050

1051 The following articles may be helpful for understanding memory management issu es:

1052 @li An article by Don Box in a

1053 <a href="http://www.microsoft.com/msj/1196/activex1196.aspx">Q & A section</a >

1054 of the November 1996 edition of the Microsoft Systems Journal.

1059 @subsection _arrayConsideration Special Consideration when using Arrays

1060 There are several methods which return arrays. It is considered a best practi ce

1061 for the client to allocate and free the arrays. This can be done for

1062 IAccessible2::relations and IAccessibleRelation::targets. However, due to the

1063 coding of the IDL for the remaining methods which return arrays, the server mu st

1064 allocate the array and the client must free the array when no longer needed.

1065 These methods are IAccessible2::extendedStates, IAccessible2::localizedExtende dStates,

1066 IAccessibleAction::keyBinding, IAccessibleTable::selectedChildren,

1067 IAccessibleTable::selectedColumns, and IAccessibleTable::selectedRows. For th ose

1068 methods, the server must allocate both the top level array and any storage

1069 associated with it, e.g. for BSTRs. The client must use CoTaskMemFree to free

1070 the array and any BSTRs must be freed with SysFreeString.

1071

1072 Also, the IDL for those methods includes an extraneous [in] parameter for the

1073 caller to specify the max size of the array. This parameter will be ignored b y

1074 the COM server.

1075

1076 @section _indexes Zero and One Based Indexes

1077 Unless otherwise specified all offsets and indexes are 0 based.

1078

1079 @section _enums Enums

1080 Note that enums start at 0.

1081

1082 @section _specialOffsets Special Offsets for use in the IAccessibleText and IAc cessibleEditableText Methods

1083 IAccessibleText and IAccessibleEditableText can use one or more of the followi ng

1084 special offset values. They are defined in the ::IA2TextSpecialOffsets enum.

1085 @li Using ::IA2_TEXT_OFFSET_LENGTH (-1) as an offset in any of the IAccessible Text or

1086 IAccessibleEditableText methods is the same as specifying the length of the s tring.

1087 @li Using ::IA2_TEXT_OFFSET_CARET (-2) as an offset for IAccessibleText::textB eforeOffset,

1088 IAccessibleText::textAtOffset, and IAccessibleText::textAfterOffset indicates that the

1089 text related to the physical location of the caret should be used. This is n eeded for

1090 applications that consider the character offset of the end of one line (as re ached by

1091 pressing the End key) the same as the offset of the first character on the ne xt line.

1092 Since the same offset is associated with two different lines a special means is needed

1093 to fetch text from the line where the caret is physically located.

1094

1095 @section _dicoveringInterfaces Discovery of Interfaces

1096 In general AT (Assistive Technology) should try IAccessible2 interfaces, follo wed by using

1097 the MSAA (Microsoft® Active Accessibility®) interfaces. (In cases whe re the an application

1098 is known to have custom interfaces which provide information not supplied by I Accessible2

1099 or MSAA, then those custom interfaces can be used.) The AT can then, by defau lt, support

1100 unknown IAccessible2/MSAA applications, without the application developers hav ing to request

1101 AT vendors for support on an individual application by application basis.

1102

1103 When you have a reference to an IAccessible and require a reference to an IAcc essible2 use

1104 QueryService as follows:

1105 @code

1106 // pAcc is a reference to the accessible object's IAccessible interface.

1107 IServiceProvider *pService = NULL;

1108 hr = pAcc->QueryInterface(IID_IServiceProvider, (void **)&pService);

1109 if(SUCCEEDED(hr)) {

1110 IAccessible2 *pIA2 = NULL;

1111 hr = pService->QueryService(IID_IAccessible, IID_IAccessible2, (void**)&pIA2 );

1112 if (SUCCEEDED(hr) && pIA2) {

1113 // The control supports IAccessible2.

1114 // pIA2 is the reference to the accessible object's IAccessible2 interface .

1115 }

1116 }

1117 @endcode

1118

1119 @section _changingInterfaces Changing between Accessible Interfaces

1120 Note that developers must always implement MSAA's IAccessible and, if needed, some

1121 of the interfaces in the set of IAccessible2 interfaces. Although the IAccess ible2

1122 IDL is currently coded such that IAccessible2 is a subclass of MSAA's IAccessi ble,

1123 none of MSAA's IAccessible methods are overridden or extended. In order to al low

1124 future removal of the inheritance, Assistive Technologies (ATs) should not rel y on

1125 that inheritance.

1126

1127 QueryService must be used to switch from a reference to an MSAA IAccessible in terface

1128 to another interface. This has been

1129 <a href="http://www.accessinteropalliance.org/docs/Introducing_IAccessibleEx.d oc">

1130 documented by Microsoft</a> and the pertinent facts have been extracted below:

1131

1132 @par

1133 Why use QueryService instead of just using QueryInterface to get IAccessibleE x

1134 directly? The reason is that since MSAA 2.0, clients don't talk to a server's

1135 IAccessible interface directly; instead they talk to an intermediate MSAA-pro vided

1136 wrapper that calls through to the original IAccessible. This wrapper provides services

1137 such as implementing IDispatch, supplying information from MSAA 2.0's Dynamic Annotation

1138 service, and scaling locations when running on Windows Vista with DPI scaling enabled.

1139 QueryService is the supported way to expose additional interfaces from an exi sting

1140 IAccessible and was originally used by MSHTML to expose IHTMLElement objects corresponding

1141 to IAccessibles. QueryService is often more convenient for servers to impleme nt than

1142 QueryInterface because it does not have the same requirements for preserving object

1143 identity or symmetry/transitivity as QueryInterface, so QueryService allows s ervers to

1144 easily implement the interface on the same object or a separate object. The l atter is

1145 often hard to do with QueryInterface unless the original object supports aggr egation.

1146

1147 Two related references in MSDN® are:

1148 @li <a href="http://msdn.microsoft.com/en-us/library/ms696078(VS.85).aspx">

1149 "Using QueryService to expose a native object model interface for an IAccessib le object"</a>

1150 @li <a href="http://msdn.microsoft.com/en-us/library/ms528415.aspx#acc_obj">

1151 "Accessing the Internet Explorer Object Associated with an Accessible Object"< /a>

1152

1153 Based on this information from Microsoft, QueryService must be used to switch back and forth

1154 between a reference to an MSAA IAccessible interface and any of the IAccessibl e2 interfaces.

1155

1156 Regarding switching between any of the IAccessible2 interfaces, applications i mplementing

1157 IAccessible2 should implement the IAccessible2 interfaces on a single object s ince ATs

1158 will be using QueryInterface to switch between the IAccessilbe2 interfaces. I mplementing

1159 the IAccessible2 interfaces on separate objects would require the use of Query Service.

1160 There is one exception, IAccessibleApplication can be implemented on a separat e object so

1161 its common code doesn't have to be included in each accessible object. ATs sh ould use

1162 QueryService to access IAccessibleApplication.

1163

1164 @section _applicationInfo Access to Information about the Application

1165 Servers implementing IAccessible2 should provide access to the IAccessibleAppl ication

1166 interface via QueryService from any object so that ATs can easily determine sp ecific

1167 information about the application such as its name or version.

1168

1169 @section _childIDs Child IDs

1170 The IAccessible2 interfaces do not support child IDs, i.e. simple child elemen ts.

1171 Full accessible objects must be created for each object that supports IAccessi ble2.

1172 Therefore MSAA's get_accChild should never return a child ID (other than CHILD ID_SELF)

1173 for an object that implements any of the IAccessible2 interfaces.

1174

1175 Microsoft's UI Automation specification has the same limitation and this was r esolved

1176 in the UI Automation Express specification by adding IAccessibleEx::GetObjectF orChild

1177 and IAccessibleEx::GetIAccessiblePair. These methods allow mapping back and f orth

1178 between an IAccessibleEx and an {IAccessible, Child ID} pair. A future versio n of

1179 IAccessible2 may include similar methods to map back and forth between an IAcc essible2

1180 and an {IAccessible, Child ID} pair.

1181

1182 @section _variants VARIANTs

1183 Some methods return a VARIANT. Implementers need to make sure that the return type is

1184 specified, i.e. VT_I4, VT_IDISPATCH, etc. The methods that return VARIANTs ar e

1185 IAccessibleHyperlink::anchor, IAccessibleHyperlink::anchorTarget, IAccessibleV alue::currentValue,

1186 IAccessibleValue::maximumValue, IAccessibleValue::minimumValue.

1187

1188 @section _iaaction-iahyperlink IAccessibleHyperlink as subclass of IAccessibleA ction

1189 In this version of the IDL, IAccessibleHyperlink is a subclass of IAccessibleA ction.

1190 However, there is no practical need for that inheritance and in some cases, su ch as

1191 an image map of smart tags, it doesn't make sense because such an image map do esn't

1192 have actionable objects; it's the secondary smart tags that are actionable. A s a

1193 result, implementations should not rely on the inheritance as it may be remove d in

1194 a later version of the IDL.

1443

1444 The uniqueID is not related to:

1445 - the MSAA objectID which is used by the server to disambiguate between

1446 IAccessibles per HWND or

1447 - the MSAA childID which is used to disambiguate between children being

1448 managed by an IAccessible.

1449

1450 This value is provided so the AT can have access to a unique runtime persiste nt

1451 identifier even when not handling an event for the object.

1452

1453 An example of when this value is useful is if the AT wants to build a cache.

1454 The AT could cache the uniqueIDs in addition to other data being cached.

1455 When an event is fired the AT could map the uniqueID to its internal model.

1456 Thus, if there's a REORDER/SHOW/HIDE event the AT knows which part of the

1457 internal structure has been invalidated and can refetch just that part.

1458

1459 This value can also be used by an AT to determine when the current control

1460 has changed. If the role is the same for two controls that are adjacent in

1461 the tab order, this can be used to detect the new control.

1462

1463 Another use of this value by an AT is to identify when a grouping object has

1464 changed, e.g. when moving from a radio button in one group to a radio button in a

1465 different group.

1466

1467 One means of implementing this would be to create a factory with a 32 bit num ber

1468 generator and a reuse pool. The number generator would emit numbers starting

2562 /** @brief This interface represents hyperlinks.

2563

2564 This interface represents a hyperlink associated with a single substring

2565 of text or single non-text object. Non-text objects can have either a

2566 single link or a collection of links such as when the non-text object is

2567 an image map.

2568

2569 Linked objects and anchors are implementation dependent. This interface is deri ved

2570 from IAccessibleAction. IAccessibleAction::nActions is one greater than the

2571 maximum value for the indices used with the methods of this interface.

2572

2573 Furthermore, the object that implements this interface has to be connected

2574 implicitly or explicitly with an object that implements IAccessibleText.

2575 IAccessibleHyperlink::startIndex and IAccessibleHyperlink::endIndex are

2576 indices with respect to the text exposed by IAccessibleText.

2577

2578 This interface provides access to a single object which can have multiple actio ns.

2579 An example is an image map which is an image with multiple links each of which is

2580 associated with a separate non-overlapping area of the image. This interface could

2581 also be applied to other kinds of objects with multiple actions such as "smart tags"

2582 which are objects, typically strings, which have multiple actions such as

2583 "Activate URI", "Bookmark URI", etc.

2584

2585 An interesting use case is an image map where each area is associated with mult iple

2586 actions, e.g. an image map of smart tags. In this case you would have to impl ement

2587 two levels of accessible hyperlinks. The first level hyperlinks would only im plement

2588 anchor and anchorTarget. The anchors would all reference the image object. T he

2589 anchorTargets would reference the second level accessible hyperlink objects. None

2590 of the IAccessibleAction methods would be implemented on the first level hyper link

2591 objects. The second level hyperlink objects would implement the IAccessibleAc tion

2592 methods. Their anchors would also reference the image object and their anchor Targets

2593 would reference URLs or the objects that would be activated.

2594

2595 This use case demonstrates that in some cases there is no need for IAccessibleH yperlink

2596 to derive from IAccessibleAction. As a result it may be removed in a later ve rsion of

2597 the IDL and it is suggested that implementations should not rely on the inheri tance.

2820 /** @brief This interface gives access to a two-dimensional table.

2821

2822 Typically all accessible objects that represent cells or cell-clusters of a tab le

2823 will be at the same time children of the table. In this case IAccessible2::in dexInParent

2824 will return the child index which then can be used when calling IAccessibleTab le::rowIndex

2825 and IAccessibleTable::columnIndex.

2826

2827 However, in some cases that kind of implementation will not be possible. When

2828 the table cells are not direct children of a table, the object representing

2829 the cell can define a "table-cell-index" object attribute identifying the 0

2830 based table cell index. This object attribute is obtained by parsing the

2831 attribute string returned by IAccessible2::attributes. The "table-cell-index"

2832 attribute can be used just like a child index of the typical case. ATs should

2833 first test for the presence of the "table-cell-index" attribute and if it is n ot

2834 present then IAccessible2::indexInParent can be used as in the typical case

2835 where cells are direct children of the table.

2836

2837 The range of valid coordinates for this interface are implementation dependent.

2838 However, that range includes at least the intervals from the from the first ro w

2839 or column with the index 0 up to the last (but not including) used row or colu mn

2840 as returned by IAccessibleTable::nRows and IAccessibleTable::nColumns.

2843 rather than this interface.
