Re: Issue 650 Does the Hover or focus SC apply to tabbed interfaces?

I don’t think that this SC is a problem for a set of tabs or for a menu.

For a set of tabs, I agree with Alastair that the content within other tabs is not additional content, it is part of the page content, but even if it was regarded as additional, the set of tabs is focused and what is changing is the selection, so this SC doesn’t apply.

For a menu system, if I move my mouse pointer over an item that triggers a pop-out, I think that all of the items within this SC are appropriate.

Is there another problem that I’m not aware of?

Thanks,

issue #650 to which I'm assigned

They ask if the hover or focus SC applies to tabbed interfaces...


The issue is significant as far as I can see. Initially, I wanted to say no because in general tabs don't change on hover. However, many tabbed interfaces change on focus. Such as the wai aria best practices example.

https://www.w3.org/TR/wai-aria-practices-1.1/examples/tabs/tabs-1/tabs.html<https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.w3.org%2FTR%2Fwai-aria-practices-1.1%2Fexamples%2Ftabs%2Ftabs-1%2Ftabs.html&data=02%7C01%7Cakirkpat%40adobe.com%7C7ca02e01f6f64e35d34508d554a98e83%7Cfa7b1b5a7b34438794aed2c178decee1%7C0%7C0%7C636508009575940072&sdata=1FBrOg42EtFN5xyCw94kNF5Rjeqdc3Uk7UOJ7yz4U30%3D&reserved=0>

The SC says that it must be able to "dismiss the additional content without moving pointer hover or keyboard focus" The way to dismiss a tab with a keyboard is to move focus to the next tab. Tabbed interfaces don't have a little "x" and you'd have to move focus even if there was. The problem in the SC seems to be "without moving pointer hover or keyboard focus" in the first bullet. It seems we'll need to amend the SC to say something like:
·         Dismissable: A mechanism is available to dismiss the additional content from within the new content or by moving focus away from the control that activated it, ...;

It seems like a real problem.


Cheers,
David MacDonald
