QUESTION
I have a textblock (ContentTextBlock
) with AutomationProperties.LiveSettings="Assertive"
. I'm just testing and checking how useful this feature is. And... am disappointed so far.
ANSWER
Answered 2019-Jan-28 at 12:47Whilst I didn't manage to get live regions to work, I found another workaround:
Tolk is a library which can, among oterrs
- Detect which supported screen reader, if any, is running
- Pass strings to the screen reader's speech engine and braille.
- Also has support for SAPI
To include Tolk in your C# project, download it from the link above, then include tolk.cs
(from src/dotnet
) in your project, and place tolk.dll
(it's found in bin
) in the folder with your executable (or somewhere in the PATH variable). Make sure that the dll version matches your CPU target (x86/x64). Do the same for the dlls in the lib directory. Then you can use it according to the code found in the examples folder.
PS. Tolk works on Win 7 as well, so that's a bonus. The live-regions of WPF were only supported from Win 8 on.
QUESTION
tl;dr: How would I implement an accessible popover? (I'm using bootstrap at the moment, but open to any ideas)
One of the biggest accessibility problems I face is the use of popovers when providing extra help information.
The way I understand it, popovers (and I guess more broadly, modals) are used for extra information when a tooltip cannot suffice. Popovers require the user to "open/click/activate" a help button for a new DOM element to be appended (or otherwise displayed), with the help information. While tooltips passively shows/speaks information whenever a user focuses the element. The tooltip widget itself is still being considered by WAI-ARIA
Say I have a text-input field with a label. I want to attach supplementary content to that input, in the form of a clickable/actionable button. Initially I had the popover button in the label, before finding out the hard way that label's can't have block-level child elements.
I'm aware this probably isn't the best way of implementing an accessible popover. Here is my help button:

Answered 2018-Mar-13 at 22:45It doesn't necessarily have to be a live region. It feels more like a modal dialog, especially if you have interactive elements in it, such as the hide button.
There's a working example of an accessible modal dialog on https://github.com/gdkraus/accessible-modal-dialog
