Great!

You only need to define a QML Gesture Area and implement onSwipe method (with desired angle) as a trigger to launch the next/previous page action.

Beware that if the are is near the borders, you need to disable global swipe gestures in fullscreen more to avoid the "swipe to menu" feature while you are reading pages. You can reenable it when showing the toolbar. Check this post as an example, although it might be other ways to handle that.
