accessible-event listener

Steps to reproduce:
1. Launch the accessible-event listener in a terminal
2. Open the attached test case
3. Click once or arrow in the document text

Expected results: The objects embedded in the paragraph would be listed in the terminal.

Actual results: The objects embedded in the paragraph are not listed.

Equivalent html test case

Results when performing the same test using Epiphany and Firefox -- having first enabled caret-navigation by pressing F7:

Epiphany:

[paragraph | ] has 2 hyperlinks
	0. (chars: 10 - 11) [image | Foo!]
	1. (chars: 26 - 28) [entry | foo]

---------

Firefox:

[paragraph | ] has 2 hyperlinks
	0. (chars: 10 - 11) [text | Foo!]
	1. (chars: 26 - 27) [entry | ]

Lastly, please note that this also applies to comments -- at least. Or to put it a different way: Whenever there is a replaced object character in the text, the object it "replaces" should be obtainable reliably via AtkHypertext and AtkHyperlinImpl.

Qubit - thoughts on this one? You're mot up to speed on Accessibility issues than I am. Thanks!
Comment 5 Jacobo Aragunde Pérez 2014-07-10 12:24:09 UTC
The implementation of hyperlinks in LibreOffice is not complete, according to bug #35107 and it would still require some work.

As for comments, the use of AtkHyperlink would match its documentation and the fix should be easier because comments are already accessible objects.

TESTING on Ubuntu 14.04 + LO 4.4.0.2

CONFIRMED -- the listener showed that LibreOffice was not providing information about any hyperlinks in the document.

Dear all,

This bug also affects images: they are not visible for screen reader users.

Best regards.

Comment 15 Joanmarie Diggs 2024-06-12 11:23:34 UTC
Michael: I just confirmed that what is described in the opening report is still an issue. The impact is that Orca says nothing for the embedded objects because it has no way of retrieving them.

Orca needs to be able to retrieve the embedded objects via the Hypertext interface as Hyperlink objects. (Yes, I know the embedded objects are not links. The API is unfortunately named.)

The embedded objects should implement the hyperlink interface so that Orca can retrieve the following:

* The actual accessible objects
* The start and end character offsets of the embedded objects with respect to their parent paragraph.

Given that IA2 has similar interfaces, my guess is this bug also impacts NVDA.
