Accessible.announce

void announce(string message, gtk.types.AccessibleAnnouncementPriority priority)

Requests the user's screen reader to announce the given message.

This kind of notification is useful for messages that either have only a visual representation or that are not exposed visually at all, e.g. a notification about a successful operation.

Also, by using this API, you can ensure that the message does not interrupts the user's current screen reader output.

Parameters

`message`	the string to announce
`priority`	the priority of the announcement
