1950785 - Caret isn't updated correctly if set on a document by UIA

Status: RESOLVED WORKSFORME

(Core :: Disability Access APIs, defect)

Description

[James Teh [:Jamie]]

If you set the caret on a document using IA2's IAccessibleText::setCaretOffset, the caret is updated correctly. Calling IAccessibleText::caretOffset to retrieve it returns the updated offset. In contrast, if you set the caret on a document using UIA's ITextProvider::SetSelection, the caret isn't updated correctly. Calling ITextProvider::GetSelection doesn't reflect the change.

For IAccessibleText, we use HyperTextAccessible::SetCaretOffset, which calls SetSelectionRange. This in turn updates the caret with nsFocusManager. For ITextProvider, we use TextLeafRange::SetSelection, which doesn't call nsFocusManager.

I'm not sure what I did wrong in my testing, but this appears to be incorrect and this particular use case works as expected. I still think it's worth unifying the caret setting code to be consistent, both in code path and how it behaves, but that's not a UIA bug.
