Subject: [PATCH] add virtual destructor to
 QWindowSystemInterfacePrivate::WindowSystemEvent
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a virtual destructor to
QWindowSystemInterfacePrivate::WindowSystemEvent class. Otherwise, in
QWindowSystemInterface::sendWindowSystemEvents() "delete event" can't
destruct the subclass of WindowSystemEvent properly.
