Bug 119829 – IAccessibleText/2 implementation for AppleWindows port

• Component: Accessibility
• Status: RESOLVED FIXED

[Roger Fong]

Implement IAccessibleText and IAccessibleText2.

The first patch is a bit of a rough draft.
First patch implements some of the more obvious core methods.

Draft Patch

This is a preliminary patch.
I've yet to test it using NVDA but most of it's straightforward.

This patch is fairly large, I will split it up into smaller patches once I
figure out a good way to divide things up (which will depend on the importance of the methods to NVDA)

If anyone is willing to brave taking a quick cursory glance of it just to point out any glaring mistakes that would be grand.
No pressure tho.

I'll upload some more tested, more split up patches tomorrow, but a preliminary review would definitely help expedite the process.
Thanks

I think this looks great!  Sorry this turned into a larger project than I had originally envisioned. :(

> Source/WebKit/win/AccessibleText.cpp:63
> +HRESULT AccessibleText::attributes(long offset, long *startOffset, long *endOffset, BSTR *textAttributes)

The asterisk is part of the type! Please write long* startOffset, etc.

> Source/WebKit/win/AccessibleText.cpp:73
> +HRESULT AccessibleText::caretOffset(long *offset)

Ditto

> Source/WebKit/win/AccessibleText.cpp:76
> +        return E_FAIL;

We usually check that the pointer argument is non-null and return E_POINTER if we are called without a valid pointer. This applies to the other methods as well.

> Source/WebKit/win/AccessibleText.cpp:205
> +    int previous_pos = std::max(0, (int)(offset-1));

Need a C++ cast here...

> Source/WebKit/win/AccessibleText.cpp:528
> +    else

No need for this else case. Just return offset.

there's a document() method on axObject that you can call that will check if renderer() exists. you should probably verify that that document exists after retrieving

ditto for document()

> Source/WebKit/win/AccessibleText.cpp:135

there's a node() method on axObject. you should prob. verify it exists after retrieving

> +    int textLength = m_object->text().length();

length() returns an unsigned here

do you want to use m_object->textLength() here in case of password fields?

[Roger Fong]

I've made the suggested changes.

Two things I'm having issues with however.

1. When to create a new AccessibleText object.
This is controlled by the isTextControl() method is AccessibilityObject.cpp

Currently this returns true if the role is 
    case TextAreaRole:
    case TextFieldRole:
    case ComboBoxRole:
	case StaticTextRole:
	case ListItemRole:
(I've added the last 2)

I'm not sure that this is correct hwoever.

Another issue is that in the query interface method, I only ever seem to hit the IAccessibleText case. Never IAccessibleText2 or IAccessibleEditableText,

although the functionality of say copy paste using NVDA commands seems to work regardless.

This is a tad confusing because an IAccessibleText2 is an IAccessibleText.
The way things are organized right now, AccesibleBase implements IAccessibleText2 (which inherits from IAccessibleText) and from IAccessibleEditableText. Since NVDA supposedly uses IAccessible2 shouldn't it always be seeing the IAccessibleText2 uiid case?

My second patch adds those files...
Hmm I guess I'll need to commit both patches at the same time to minimize build breakage.
Or we can just go with the larger patch, which'll just do everything at once.

Is checking the existence of m_object->renderer()->document() not the same thing?
I do that in the initialCheck method.

I think it's cleaner if we don't have to ask for the renderer() object. I think the platform implementations should try hard to work mainly through the WebCore AccessibilityObject interface rather than diving into objects it holds on to.

There's also a chance that renderer() disappears or doesn't exist for the object because maybe in a <canvas>

Ok I've replaced all calls to renderer->document with jsut document, including in the initialcheck method.
