Some goals that have hopefully been achieved are: - make QPointerEvent and QEventPoint resemble their Qt Quick counterparts to such an extent that we can remove those wrappers and go back to delivering the original events in Qt Quick - make QEventPoint much smaller than QTouchEvent::TouchPoint, with no pimpl - remove most public setters - reduce the usage of complex constructors that take many arguments - don't repeat ourselves: move accessors and storage upwards rather than having redundant ones in subclasses - standardize the set of accessors in QPointerEvent - maintain source compatibility as much as possible: do not require modifying event-handling code in any QWidget subclass To avoid public setters we now introduce a few QMutable* subclasses. This is a bit like the Builder pattern except that it doesn't involve constructing a separate disposable object: the main event type can be cast to the mutable type at any time to enable modifications, iff the code is linked with gui-private. Therefore event classes can have less-"complete" constructors, because internal Qt code can use setters the same way it could use the ones in QTouchEvent before; and the event classes don't need many friends. Even some read-accessors can be kept private unless we are sure we want to expose them.
