Hi everybody,
in our application we do custom drawing. To make it accessible we create
wrapper-objects (subclasses of NSView) that implement the
NSAccessibility protocol for each control. This works fine for buttons,
checkboxes etc.
To let Voice Over read text input we tried to send
NSAccessibilityValueChangedNotification whenever the user changes the
text. We hoped that Voice Over would then read the text. But it didn't.
On the other hand in a standard cocoa text input area Voice Over speaks
(depending on its configuration) each typed character/word and selected
text. Through which API calls is this behaviour triggered?
Regards
Frank
