+ @section _errors Error Handling |
+ HRESULT values are defined by the Microsoft® Win32® API. For more information, refer to |
+ <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/aa378137%28v=vs.85%29.aspx"> |
+ Interpreting HRESULT Values</a> in MSDN®. |
+ |
+ Note that the S_FALSE return value is considered a non-error value and the |
+ SUCCEEDED macro will return TRUE. S_FALSE is used when there is no failure |
+ but there was nothing valid to return, e.g. in IAccessible2::attributes when |
+ there are no attributes. When S_FALSE is returned [out] pointer types should |
+ be NULL and [out] longs should generally be 0, but sometimes -1 is used such |
+ as IAccessible2::indexInParent, IAccessibleText::caretOffset, and |
+ IAccessibleHypertext::hyperlinkIndex. |
+ |
+ Note that for BSTR [out] variables common COM practice is that the server does |
+ the SysAllocString and the client does the SysFreeString. Also note that when |
+ NULL is returned there is no need for the client to call SysFreeString. Please |
+ refer to the documentation for each method for more details regarding error handling. |
+ |
+ @section _memory Memory Management |
+ The following memory management issues should be considered: |
+ @li Although [out] BSTR variables are declared by the client, their space is |
+ allocated by the server. They need to be freed with SysFreeString by the |
+ client at end of life; the same is true when BSTRs are used in structs or |
+ arrays which are passed to the server. |
+ @li If there is no valid [out] BSTR to return, the server should return S_FALSE and |
+ assign NULL to the output, e.g. *theOutBSTR = NULL;. |
+ @li COM interfaces need to be referenced with AddRef when used and dereferenced |
+ with Release at end of life. |
+ @li Single [out] longs, HWNDs, booleans, and structs are declared by the caller |
+ and passed by reference. The marshaller does all the memory management. |
+ |
+ The following articles may be helpful for understanding memory management issues: |
+ @li An article by Don Box in a |
+ <a href="http://www.microsoft.com/msj/1196/activex1196.aspx">Q & A section</a> |
+ of the November 1996 edition of the Microsoft Systems Journal. |
+ @li A posting to a CodeGuru forum, |
+ <a href="http://www.codeguru.com/forum/showthread.php?t=364511">Windows SDK |
+ String: What are the rules for BSTR allocation and deallocation?</a> |
+ |
+ @subsection _arrayConsideration Special Consideration when using Arrays |
+ There are several methods which return arrays. In the case of IAccessible2::relations |
+ and IAccessibleRelation::targets the client must allocate and free the arrays. |
+ |
+ For the remaining methods which return arrays, the server must allocate the array |
+ and the client must free the array when no longer needed. These methods are |
+ IAccessible2::extendedStates, IAccessible2::localizedExtendedStates, |
+ IAccessible2_2::relationTargetsOfType, IAccessibleAction::keyBinding, |
+ IAccessibleHypertext2::hyperlinks, IAccessibleTable::selectedChildren, |
+ IAccessibleTable::selectedColumns, IAccessibleTable::selectedRows, |
+ IAccessibleTable2::selectedCells, IAccessibleTable2::selectedColumns, |
+ IAccessibleTable2::selectedRows, IAccessibleTableCell::columnHeaderCells, |
+ and IAccessibleTableCell::rowHeaderCells. |
+ For those methods, the server must allocate both the top level array and any storage |
+ associated with it, e.g. for BSTRs. The server must allocate the arrays with |
+ CoTaskMemAlloc and any BSTRs with SysAllocString. The client must use CoTaskMemFree |
+ to free the array and any BSTRs must be freed with SysFreeString. |
+ |
+ Also, the IDL for IAccessible2::extendedStates, IAccessible2::localizedExtendedStates, |
+ IAccessibleAction::keyBinding, IAccessibleTable::selectedChildren, |
+ IAccessibleTable::selectedColumns, and IAccessibleTable::selectedRows includes an |
+ extraneous [in] parameter for the caller to specify the max size of the array. |
+ This parameter will be ignored by the COM server. |
+ |
+ @section _indexes Zero and One Based Indexes |
+ Unless otherwise specified all offsets and indexes are 0 based. |
+ |
+ @section _enumBase Enum Base |
+ Note that enums start at 0. |
+ |
+ @section _specialOffsets Special Offsets for use in the IAccessibleText and IAccessibleEditableText Methods |
+ IAccessibleText and IAccessibleEditableText can use one or more of the following |
+ special offset values. They are defined in the ::IA2TextSpecialOffsets enum. |
+ @li Using ::IA2_TEXT_OFFSET_LENGTH (-1) as an offset in any of the IAccessibleText or |
+ IAccessibleEditableText methods is the same as specifying the length of the string. |
+ @li Using ::IA2_TEXT_OFFSET_CARET (-2) as an offset for IAccessibleText::textBeforeOffset, |
+ IAccessibleText::textAtOffset, and IAccessibleText::textAfterOffset indicates that the |
+ text related to the physical location of the caret should be used. This is needed for |
+ applications that consider the character offset of the end of one line (as reached by |
+ pressing the End key) the same as the offset of the first character on the next line. |
+ Since the same offset is associated with two different lines a special means is needed |
+ to fetch text from the line where the caret is physically located. |
+ |
+ @section _dicoveringInterfaces Discovery of Interfaces |
+ In general AT (Assistive Technology) should try IAccessible2 interfaces, followed by using |
+ the MSAA (Microsoft® Active Accessibility®) interfaces. (In cases where the an application |
+ is known to have custom interfaces which provide information not supplied by IAccessible2 |
+ or MSAA, then those custom interfaces can be used.) The AT can then, by default, support |
+ unknown IAccessible2/MSAA applications, without the application developers having to request |
+ AT vendors for support on an individual application by application basis. |
+ |
+ When you have a reference to an IAccessible and require a reference to an IAccessible2 use |
+ QueryService as follows: |
+ @code |
+ // pAcc is a reference to the accessible object's IAccessible interface. |
+ IServiceProvider *pService = NULL; |
+ hr = pAcc->QueryInterface(IID_IServiceProvider, (void **)&pService); |
+ if(SUCCEEDED(hr)) { |
+ IAccessible2 *pIA2 = NULL; |
+ hr = pService->QueryService(IID_IAccessible, IID_IAccessible2, (void**)&pIA2); |
+ if (SUCCEEDED(hr) && pIA2) { |
+ // The control supports IAccessible2. |
+ // pIA2 is the reference to the accessible object's IAccessible2 interface. |
+ } |
+ } |
+ @endcode |
+ |
+ @section _changingInterfaces Changing between Accessible Interfaces |
+ Note that developers must always implement MSAA's IAccessible and, if needed, some |
+ of the interfaces in the set of IAccessible2 interfaces. Although the IAccessible2 |
+ IDL is coded such that IAccessible2 is a subclass of MSAA's IAccessible, none of |
+ MSAA's IAccessible methods are redefined by IAccessible2. |
+ |
+ QueryService must be used to switch from a reference to an MSAA IAccessible interface |
+ to another interface. This has been |
+ <a href="http://www.atia.org/files/public/Introducing_IAccessibleEx.doc"> |
+ documented</a> and the pertinent facts have been extracted below: |
+ |
+ @par |
+ Why use QueryService instead of just using QueryInterface to get IAccessibleEx |
+ directly? The reason is that since MSAA 2.0, clients don't talk to a server's |
+ IAccessible interface directly; instead they talk to an intermediate MSAA-provided |
+ wrapper that calls through to the original IAccessible. This wrapper provides services |
+ such as implementing IDispatch, supplying information from MSAA 2.0's Dynamic Annotation |
+ service, and scaling locations when running on Windows Vista with DPI scaling enabled. |
+ QueryService is the supported way to expose additional interfaces from an existing |
+ IAccessible and was originally used by MSHTML to expose IHTMLElement objects corresponding |
+ to IAccessibles. QueryService is often more convenient for servers to implement than |
+ QueryInterface because it does not have the same requirements for preserving object |
+ identity or symmetry/transitivity as QueryInterface, so QueryService allows servers to |
+ easily implement the interface on the same object or a separate object. The latter is |
+ often hard to do with QueryInterface unless the original object supports aggregation. |
+ |
+ Two related references in MSDN® are: |
+ @li <a href="http://msdn.microsoft.com/en-us/library/ms696078(VS.85).aspx"> |
+ "Using QueryService to expose a native object model interface for an IAccessible object"</a> |
+ @li <a href="http://msdn.microsoft.com/en-us/library/ms528415.aspx#acc_obj"> |
+ "Accessing the Internet Explorer Object Associated with an Accessible Object"</a> |
+ |
+ Based on this information from Microsoft, QueryService must be used to switch back and forth |
+ between a reference to an MSAA IAccessible interface and any of the IAccessible2 interfaces. |
+ |
+ Regarding switching between any of the IAccessible2 interfaces, applications implementing |
+ IAccessible2 should implement the IAccessible2 interfaces on a single object since ATs |
+ will be using QueryInterface to switch between the IAccessilbe2 interfaces. Implementing |
+ the IAccessible2 interfaces on separate objects would require the use of QueryService. |
+ There is one exception, IAccessibleApplication can be implemented on a separate object so |
+ its common code doesn't have to be included in each accessible object. ATs should use |
+ QueryService to access IAccessibleApplication. |
+ |
+ @section _applicationInfo Access to Information about the Application |
+ Servers implementing IAccessible2 should provide access to the IAccessibleApplication |
+ interface via QueryService from any object so that ATs can easily determine specific |
+ information about the application such as its name or version. |
+ |
+ @section _childIDs Child IDs |
+ The IAccessible2 interfaces do not support child IDs, i.e. simple child elements. |
+ Full accessible objects must be created for each object that supports IAccessible2. |
+ Therefore MSAA's get_accChild should never return a child ID (other than CHILDID_SELF) |
+ for an object that implements any of the IAccessible2 interfaces. |
+ |
+ Microsoft's UI Automation specification has the same limitation and this was resolved |
+ in the UI Automation Express specification by adding IAccessibleEx::GetObjectForChild |
+ and IAccessibleEx::GetIAccessiblePair. These methods allow mapping back and forth |
+ between an IAccessibleEx and an {IAccessible, Child ID} pair. A future version of |
+ IAccessible2 may include similar methods to map back and forth between an IAccessible2 |
+ and an {IAccessible, Child ID} pair. |
+ |
+ @section _variants VARIANTs |
+ Some methods return a VARIANT. Implementers need to make sure that the return type is |
+ specified, i.e. VT_I4, VT_IDISPATCH, etc. The methods that return VARIANTs are |
+ IAccessibleHyperlink::anchor, IAccessibleHyperlink::anchorTarget, IAccessibleValue::currentValue, |
+ IAccessibleValue::maximumValue, IAccessibleValue::minimumValue. |
+ |
+ @section _iaaction-iahyperlink IAccessibleHyperlink as subclass of IAccessibleAction |
+ In this version of the IDL, IAccessibleHyperlink is a subclass of IAccessibleAction. |
+ However, there is no practical need for that inheritance and in some cases, such as |
+ an image map of smart tags, it doesn't make sense because such an image map doesn't |
+ have actionable objects; it's the secondary smart tags that are actionable. As a |
+ result, implementations should not rely on the inheritance as it may be removed in |
+ a later version of the IDL. |
+ |

+ The names of actual companies and products mentioned herein may be the trademarks of |
+ their respective owners. In particular, Active Accessibility, Microsoft, MSDN, and Win32 |

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

+ - the MSAA childID which is used to disambiguate between children being |
+ managed by an IAccessible. |
+ |
+ This value is provided so the AT can have access to a unique runtime persistent |
+ identifier even when not handling an event for the object. |
+ |
+ An example of when this value is useful is if the AT wants to build a cache. |
+ The AT could cache the uniqueIDs in addition to other data being cached. |
+ When an event is fired the AT could map the uniqueID to its internal model. |
+ Thus, if there's a REORDER/SHOW/HIDE event the AT knows which part of the |
+ internal structure has been invalidated and can refetch just that part. |
+ |
+ This value can also be used by an AT to determine when the current control |
+ has changed. If the role is the same for two controls that are adjacent in |

+ |
+ One means of implementing this would be to create a factory with a 32 bit number |

+ at 1. Each time an object's life cycle ended, its number would be saved into a |
+ reuse pool. The number generator would be used whenever the reuse pool was empty. |
+ |

+/** @brief This interface provides clipboard capability to text objects. |
+ |
+ This interface is typically used in conjunction with the IAccessibleText |
+ interface and complements that interface with the additional capability of |
+ clipboard operations. Note that even a read only text object can support |
+ the copy capability so this interface is not limited to editable objects. |
+ |
+ The substrings used with this interface are specified as follows: |
+ If startOffset is less than endOffset, the substring starts with the |
+ character at startOffset and ends with the character just before endOffset. |
+ If endOffset is lower than startOffset, the result is the same as a call |
+ with the two arguments exchanged. The whole text can be defined by passing |
+ the indices zero and IAccessibleText::nCharacters. If both indices have the |
+ same value, an empty string is defined. |
+ |

+/** @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 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. |

+ Typically all accessible objects that represent cells or cell-clusters of a table |
+ will be at the same time children of the table. In this case IAccessible2::indexInParent |
+ will return the child index which then can be used when calling IAccessibleTable::rowIndex |
+ and IAccessibleTable::columnIndex. |
+ |
+ However, in some cases that kind of implementation will not be possible. When |
+ the table cells are not direct children of a table, the object representing |
+ the cell can define a "table-cell-index" object attribute identifying the 0 |
+ based table cell index. This object attribute is obtained by parsing the |
+ attribute string returned by IAccessible2::attributes. The "table-cell-index" |
+ attribute can be used just like a child index of the typical case. ATs should |
+ first test for the presence of the "table-cell-index" attribute and if it is not |
+ present then IAccessible2::indexInParent can be used as in the typical case |
+ where cells are direct children of the table. |
+ |
+ The range of valid coordinates for this interface are implementation dependent. |
+ However, that range includes at least the intervals from the from the first row |
+ or column with the index 0 up to the last (but not including) used row or column |
+ as returned by IAccessibleTable::nRows and IAccessibleTable::nColumns. |
+ |
+ Note that newer implementations are now using IAccessibleTable2 and IAccessibleTableCell |
+ rather than this interface. |
