Hi,

A user using Insider build 14366 reports that toasts are no longer announced.

STR:

  1. Using Insider build 14366/14367, perform an action that causes toasts to appear, such as connecting hardware.
  2. Listen for toast sound.

Expected: NVDA announces toasts.
Actual: NVDA does not announce toasts.
Cause: Accessibility event Checker (accevent) says toasts do not fire tooltip open event, only window open event is fired. This does not happen with Narrator: when toasts appear, because it listens to window open event, it announces them. I was able to reproduce this on 14366/14367, and can confirm that toasts are announced in build 10586.

Technical: NVDA's UIA handler has a map of which UIA events corresponds to NVDA events. This map does not contain window open event, yet tooltip open event is assigned to alert event. We don't want to listen to window open event, as it causes a flood of events to come through, especially for objects that we do not wish to announce. One workaround would be to tell NVDA that certain windows are safe, thereby allowing window open event from objects such as toasts to be accepted. All this changes if Microsoft fixes this before Anniversary Update (Version 1607) is released (feedback sent to Microsoft).

Thanks.

NvDAObjects/UIA/ToastWin10: recognize priority toasts such as Cortana…
… timer. re #6096

In Redstone, one can set priority to notifications, and if this happens, automation ID changes to PriorityToastView. To handle both normal and high priority toasts, use substrings.
