Re: [orca-list] Strange behavior when using the role attribute in websites

[Peter Vágner <pvagner pvagner tk>]

Hello,

Well, first thing we need to be aware of is what is the difference between browse mode and focus mode.
When orca ís switched into the browse mode it consumes some key presses e).g. arrow keys, quick navigation keys, page up / page down keys, home / end keys.
When orca is switched into the focus mode it consumes no keypresses.

Expanding from that it becomes obvious web authors have to implement keyboard navigation them-selves For made up interactive widgets. Actually this is the other way round, screen readers have adopted focus mode vs browse mode navigation paradigm because it was needed to pass some key presses to the web app.
I.e. if you tell screen readers to treat div as a toolbar, you should also implement toolbar like behaviour for that div.

Similarly for the other widgets like grids, lists, menus and more.

Greetings

Peter

It behaves just as it does on google.com with the search field. The 
toolbar is the first object that appears in the rendered html source. 
When the page loads, Orca automatically goes into focus mode. This is a 
page with Bootstrap 4 on it. Otherwise I did not set focus to the 
toolbar. I didn't know that an author had to create their own navigation 
within certain containers such as toolbar, tree, and others. I assumed 
the screen reader did it for you since JAWS and NVDA already do it. 
Sorry for the confusion.

 Sorry for being spammy. Are you saying that the first thing on your page
 is a toolbar, but you're not putting focus on it? If so, I *could* tweak
 Orca to not assume focus mode. But if the first thing on the page is a
 toolbar, it does look a bit web-appy (as opposed to texty).

 When a page loads, Orca looks to see if the author (or browser) has
 placed focus in a focus-mode (i.e. web application gui) object or form
 input. A toolbar is a web application gui object. It is assumed that if
 the author has placed you automatically inside of a toolbar, then the
 associated web application will be providing the navigation. As a
 result, Orca puts you in focus mode.

 A question back at you: Why are you putting users inside a toolbar if
 you want screen readers to treat it like textual content?

 Hi,


 Orca master, Ubuntu 19.04.


 When I design websites, I often use the role attribute with html
 elements. However, Orca presents some interesting behavior when
 interacting with these types of html elements. When Orca is presented
 with one of these controls, it goes into focus mode and doesn't interact
 with the control very well. For example, a div with role="toolbar" puts
 Orca into focus mode on the toolbar, but the only way to interact with
 the controls inside the toolbar is to press TAB rather than using the
 left/right arrows. In another instance, using role="tree" and
 role="treeitem" puts Orca into focus mode on the tree, but I can't
 interact with the tree nodes. Orca will only go into focus mode when an
 element with the role attribute is the first thing on the page. Any
 ideas what might be going on?
