Hi
For the buttons is it necessary to give advance warning opens as a
simulated dialog these buttons will opens a dialog ?
Please find the below link
https://www.webaccessibility.com/best_practices.php?technology_platform_idG
"Developers must alert users *when a link is used* to open a simulated
dialog. When *links* do not indicate the purpose of opening a simulated
dialog, users of assistive technology may expect another action and may be
confused when that expected action does not occur. Text should be added *to
the link* alerting users that a simulated dialog will be opened when the
link is activated..."
(*emphasis* added)

*This official W3 example includes a button which does NOT warn of a
pending simulated dialog*

The webaccessibility.com site is not an official w3 site nor a spec, even
if it's from a reputable company like Level Access and has great
information.
If a button does not indicate it will open a dialog, then from a strict
compliance perspective, it's not a WCAG failure. However, if the dialog
itself that pops up does not announce itself, then that would definitely be
a WCAG violation.
Should a button indicate it has a dialog? Sure, that would be great, but
indicating a dialog will popup would be great for *all* users, not just
screen reader users.
The new values of aria-haspopup
<https://www.w3.org/TR/wai-aria/#aria-haspopup> has a "dialog" value to do
exactly what you're asking about. Support for it might not be widespread
yet, but setting it would be a good idea. But again, that attribute only
helps screen reader users. It'd be nice if there was an indication for all
users.

*Ensure links that spawn dialogs indicate the fact*
"When a link (text link or image link) is used as the element that opens a
dialog, its link text must indicate this special action to Assistive
Technology users. Otherwise users would assume the link performs the
standard link action of navigating to another page and might be confused
when that standard action does not occur."
*"Note: When a button is used instead of a link to trigger a dialog, it is
not necessary to indicate the dialog action textually*. This includes
standard HTML button control types as well as the ARIA role of button."
*With best regards,*
*K.S.Meharoon*

Thanks Geln for your inputs
I fully agree, it's good for all users to know if links will open in a new
window. But do you have any good examples of accessible web sites or web
applications where buttons (not links) have such visible text? Opens a
simulated dialog.

Hi, that best practice indicates it is not required for buttons although it may be useful to some users. Specifically the best practice was created for situations such as when links are used where the user expects to be taken to a new page or somewhere else on the current page because a link rather than a button was used.
