Since there already is a one-to-one relationship between QObject and QAccessibleInterface it makes little sense to create and destroy the interfaces on each call to queryAccessibleInterface. Add a cache and keep created interfaces around for the lifetime of the corresponding QObject. This changes the memory management rules: accessible interfaces must no longer be deleted. If you get an QAccessibleIntrface pointer that pointer will stay valid as long as the corresponding QObject is not deleted. This also re-enables accessibility for Mac. We limit the range of the IDs so that they are useable for Windows directly. That means we can get rid of the event cache there. This is based on: Iebf2f374916fc70a9dd29e95f45a6444b85f6cee Change-Id: I9fe6531812c0dbc5b41101ac05830a6dd75e13a3 Reviewed-by: Morten Johan Sørvig <morten.sorvig@digia.com>
