Allow access to Microsoft Word documents via UIAutomation, providing a significant speed improvement, and ability to access documents when in-process injection is impossible. #7849

michaelDCurran · 2017-12-12T02:20:56Z

A quick note on testing this pr:
To forecefully use UIAAutomation in Microsoft Word when available, set config.conf['UIA']['useInMSWordWhenAvailable'] to True.
You can confirm that NVDA is using UIA as the role for the document will be document, rather than editableText.
Most importantly though, performance should be a lot snappier.

None

Summary of the issue:

Speed improvements

NVDA must fetch a lot of data from Microsoft Word when reading content. This results in many many calls to Microsoft Word's object model.
Although NVDA does many of these calls in-process when possible, recently due to both changes in Microsoft Word, and the growing number of calls needed, performance is getting worse.

Unable to inject

In some situations, such as when running NVDA on Windows 10 S as a store app, it is impossible for NVDA to inject into other processes. Therefore, bulk-fetching data in Microsoft Word by injection is not an option. this results in Microsoft word being completely inaccessible on Windows 10 S for NVDA.

Description of how this pull request fixes the issue:

NVDA already had preliminary support for Microsoft Word via UIAutomation as this was the way NVDA was able to access Windows 10 Mail. However, this support was limited and did not make use of all possible features.
This PR does the following:

Abstraction of table navigation scripts

For a while, browseMode has had a pretty nice abstraction of table navigation support. This support has now been moved out into a documentBase.DocumentWithTableNavigation class, which browseMode, and other document implementations can use.
Table navigation code was moved out of UIABrowseMode and into a new UIA base class of UIADocumentWithTableNavigation, allowing UIA implementations for browseMode or NVDAObjects to get standard table navigation.
The UIAutomation WordDocument NVDAObject now also inherits from this new base class, gaining table navigation support for free.
In short, table navigation scripts such as control+alt+rightArrow etc, are now available in Microsoft Word when accessed via UIAutomation.

Ensure browseMode works in Microsoft Word with UIAutomation

Some small fixes to UIATextInfo's constructor where needed so that creating a TextInfo from its root UIA NVDAObject would correctly work.

Report more formatting in UIATextInfo

Support detection of spelling errors when they are exposed along with other annotations at the same time. Previously we only supported fetching them by themselves.
Report the existance of comments.
report style name. (E.g. Microsoft Word paragraph style).
Report editor revisions including insertions and deletions.
Report line spacing.

Further specific Microsoft Word UIA enhansements

No longer announce "edit" when entering tables of contents.
Report page numbers
Ensure to report all spelling errors, not just one for the entire text chunk (if it contained one or more).
Report footnotes and endNotes within text.
Add a reportCurrentComment script (NVDA+alt+c) which reports the comment (including author and date) similar to Microsoft word support via the object model.

Allow UIA Microsoft Word support in various situations

Fallback to UIA support if it is available and injection is impossible
Forecefully use UIA if it is available and config.conf['UIA']['useInMSWordWhenAvailable'] is True. This is useful for testing the new UIA support.
Allow the UIA support to make use of the existing object model support if available for features such as reporting in format toggle scripts such as turning bold on and off.
For these changes it was necessary to move some of the older Microsoft Word support into NVDAObjects.IAccessible.winword, and only leave the object model fetching code, and some toggle scripts in NVDAObjects.window.winword.
Note that in order not to break localization gesture bindings for toggle scripts such as control+b (bold) etc, it was important to keep these toggle scripts in NVDAObjects.window.winword.

Testing performed:

Tested with config.conf['UIA']['useInMSWordWhenAvailable'] both true and false, in Microsoft Word 2016, and Windows 10 Mail. this needs much wider testing.

Known issues with pull request:

Eventually we may consider turning on UIA support in MS Word by default if available. However, we must be careful to only allow this for complete UIA implementations. I.e. it is possible that Office 2013 exposed a UIA implementation, though it may have been incomplete.
Setting / getting of user-defined header rows/columns is not supported. In MS word 2016 and higher it is recommended to actually set the header rows/columns via the Ribbon as that is now supported in Office.
Author / date info for track changes in Elements list. This is currently impossible to fetch with MS word's UIA implementation.

Even with these limitations, this is still a far far improvement for situations where injection is unavailable, thus I feel these issues should be addressed in further PRs. this is already a significant patch.

Change log entry:

From the general user's point of view there will not be any change (yet). However, once we start offering NVDA in the Windows store for Windows 10 S, support for Microsoft word will now be possible.
Changes for developers:

For document implementations such as NVDAObjects or browseMode that have a textInfo, there is now a new documentBase.documentWithTableNavigation class that can be inherited from to gain standard table navigation scripts. Please refer to this class to see which helper methods must be provided by your implementation for table navigation to work.

… UIA support, by abstracting existing browseMode table navigation code even further. Specifically: Add a new documentBase module which contains: * TextContainerObject, which is an object that can make a textInfo. It contains a TextInfo class property, as well as makeTextInfo, and selection getter and setter. This is now inherited by NVDAObject and documentTreeInterceptor. * DocumentWithTableNavigation: a TextContainerObject that contains table navigation scripts, implemented by abstraction table code that used to exist in browseMode. Now BrowseModeDocument inherits from this. UIABrowseModeDocument's _getTableCellAt was moved into its own UIADocumentWithTableNavigation class, which UIABrowseModeDocument now inherits from, and so dos the UIA WordDocument NVDAObject class, thus now giving UIA word document support table navigation outside browse mode.

…annotation types, such as for Microsoft Word. UIATextInfo: support reporting of comments. UIATextInfo: support reporting of style name (E.g. Microsoft Word styles) UIATextInfo: report insertion and deletion revisions (Though Edge and MS Word don't seem to implement this yet). UIATextInfo: report linespacing.

…g edit in tables of contents. UIA wordDocumentTextInfo: support page numbers. UIA Word document support: Always at least split by unit format when fetching formatting. Fetching formatting for the entire text chunk may not be good as some annotationTypes such as spelling return valid results for the total range, and therefore do not give the greatest resolution UIA WordDocumentTextInfo: remove som old code that detected annoying editable text nodes which no longer works. UIA word document: report existance of footnotes and endnotes within text. UIA WordDocument: add reportCurrentComment script

…VDAObject. Use UIA with Microsoft word if NVDA connot inject, or NVDA is specifically configured to do so. Choose WordDocument with IAccessible Outlook appModule: grab WordDocument code from IAccessible rather than Window

… current cell from the headers if inappropriately put there by the UIA implementation.

Brian1Gaff · 2017-12-12T10:22:24Z

As a matter of interest, One assumes that for legacy systems, ie Windows 7 or older versions of word or other apps that may use some of the old code used for Word, then the old code is used, not the new parts described. I'm only mentioning this as we don't really want to break stuff that has worked for ages accidentally.There seems to be enough agro with Outlook and other office components alredy! Brian

Notes for testing this pr:

Test with many varying word documents, though
Test document.docx might be useful as it contains headings, formatting changes, spelling errors, comments, revisions, graphics, footnotes and endnotes etc.
Testing MS Word 2010 through 2016, with the new UIA code disabled (by default), there should be no user-visible difference at all.
With the new UIA code enabled (via the config option):
MS word 2010 and 2013: there should be no user-visible change at all.
MS Word 2016: UIA should be used. Notice documents have a role of document, and performance is vastly improved. The user should be able to access all functionality they could with the UIA code disabled, even though presentation may be ever so slightly different (E.g. "list" will be reported when entering a list where this does not happen with out UIA code).
Test things such as:
Headings: reading, quicknav, elements list
links: reading, quicknav, elements list
tables: reading, table navigation commands, quick nav
announcing existance of revisions, spelling errors,
announcing existance of comments, reporting current comment
reading with sayAll
announcement of page numbers
reporting of formatting, and auto announcement of format changes (with options turned on in Document formatting settings)
announcement of styles
Reporting of toggle formatting commands (e.g. bold control+b), italic, underline, line spacing, outline level etc.

Reiterating again that the main purpose of this code for now is to provide something when injection is not available (such as in windows 10 S).
Therefore, crashes, errors, things not working at all, are the most important. Small presentation fixes can be addressed later.

…f announceEntireNewLine class viarable is true. This is false by default, but UIA WordDocument sets this to true for better list bullet reading.

… class at the very end before the base UIA class, so that subclasses of UIA can override methods and properties of EditableTextWithoutAutoSelectDetection (such as for controlling of announcement of new line text).

…ng lists. this ensures compatibility with the older MS Word implementation, and stops confusion when pressing enter for new bullets where NVDA was announcing exiting and then entering a new list.

Hi, I think that i found a Bug. 1. Open Microsoft word, opening an existing document. 2. Open elements list with insert +f7 3. From the filter elements radio button, select grammar errors 4. As a result, you will see, that MS word crashes, and elements list leaves opened. Using latest next, Windows 10 1709 16299 Installed NVDA — You are receiving this because you are subscribed to this thread.

I found another browse mode bug regarding finding:

Enter the following lines of text:
```
Hello!
How are you?
```
Go to the top of the document
Enable browse mode
Search for how

It seems that the cursor does move one cursor position to the right, but it does not move to the actual result.

fernando-jose-silva · 2018-01-08T17:52:24Z

Sorry for opening a separate call to this discussion.
As I reported in the call I opened 7903, I would just like to report that I can not read characters, words or lines when editing a cell in excel 2013 on windows 7.
I saw that as far as the menu to start this had already been approached in this discussion.
Thank you.

…AnnotationTypes variable before any point where it can be used. Specifically: If the IUIAutomationTextRange3 interface was missing, fetchAnnotationTypes was never set. It should be set to False by default.

michaelDCurran · 2018-01-11T20:49:49Z

The issue with find in browse mode is clearly a bug in MS Word's UI automation implementation. If it finds text, it returns the original text range, rather than the position of the found string. There is no way to work around this in NVDA.

Re grammar errors crash with Elements list: a test word document file would be great.

michaelDCurran · 2018-01-11T20:51:31Z

and the Windows 7 attributeError in the start menu has been fixed in the last commit to this branch.

Hi, I activated the this feature. But, I think I found an issue.
When using NVDA in mouse tracking mode, NVDA doesn't report the main text of the Word document. NVDA reports header and footer text, buttons, menus, etc. NVDA says"<current_page> content" instead reporting the text.
I'm using Office 365 ProPlus on Windows 10 64-bit Home. Windows and Office both are up to date.

LeonarddeR · 2018-12-29T14:58:52Z

@ferhatbkr: What version of NVDA did you test this? Mouse tracking should work in latest Alpha builds.

ferhatbkr · 2018-12-30T00:26:44Z

@LeonarddeR I didn't try on alpha version, only on latest stable.

zstanecic · 2018-12-30T08:11:04Z

Hi to all, I can say, that for me it works perfectly.
