accessibility

问题 I have a normal NSTableView that displays a list of tracks. I have dedicated a table column to displaying an icon that indicates which track is currently playing. I'm working on adding fuller VoiceOver support and I don't like how when each row in the table is selected the first thing said is "image". I would like to disable accessibility for that specific table column. I know I can do this by subclassing either NSTableView and/or NSTableColumn to return YES from accessibilityIsIgnored. Is

问题 I want to automate an application via Pywinauto on my laptop but all the elements are not seen. “Inspect.exe” cannot find some elements of my application on my laptop whilst it finds them on other computers.

问题 I'm working on an accessibility task for a mobile web app (HTML+Angular+ARIA). I tested some potential ways: aria-flowto and aria-owns , not working for web page tabIndex , not working In my local test with iOS 9.2.1 Safari, the default screen reader is linear way from top. Is there a way I can define elements reading order?

问题 How to get IAccessible from IHTMLElement? I have receive "Interface is not support" error. 回答1: Not all HTML elements are accessible. See Accessible HTML Elements (there's also a list of accessible elements below). You might have hit an element that is not meant to be accessible. 回答2: Use IServiceProvider::QueryService - full details at this article. Basic idea is that QueryService is like a less strict version of QI: QI requires that all the interfaces are part of the same COM object and

问题 I have a bunch of tags with background-images properties that I would like to give some content for screenreaders but I obviously can't give it an alt attribute since they are not <img> tags. Would screenreaders be able to read the content as long as I set the text color to transparent? I would not like to use display:none or visibility:hidden as I've read that screenreaders will not read those content and can also be penalized by google for hiding content. What are my options to accomplish

问题 I am trying to make my Ajax-enabled table pagination 508-compliant (accessible using JAWS version 9).

问题 I have a link within an unordered list as follows: <li class="savelink"> <a href="/save"><span>Save</span></a> </li> Normally the screen readers read "Save". Is it possible, and with which attribute, to change that without changing the actual link text? The business need is to have a link, styled with an icon. The icon will be complementary to the link text. For example: An icon of a "+" sign and a link text "menu" that is equal to the "add menu item" action. I tried aria-label, with no

问题 I have a CustomViewGroup that extends from a ViewGroup. In it I have 2 text views and 3, 4 different buttons that I inflate from different XML files. My problem is that it does not seem to be accessible. What do I need to do at my end to see whats the problem? Can you someone please point me to a good article or resource about accessibility ?
