Multi-touch events in Java on Linux: events from OS or recognize in application?

I'm trying to implement an JavaFX application which is able to make use of touch events and multi-touch gestures. I'm working with Java8 on Linux Mint 17.

I'm using a touch foil as input device. It's eGalaxTouch device (PCAP7200 series) using an EETI eGTouch driver (eGTouchD version: 2.5). It's recognized as standard mouse input device but also creates multi-touch events (ABS_MT_SLOT, ABS_MT_TRACKING_ID, ABS_MT_POSITION_X, ABS_MT_POSITION_Y) which can be read from /dev/input/eventX.

Ubuntu now comes with some multi-touch support and is able to recognize gestures. Is it possible to use those OS generated events in my application and to listen to them like to mouse events with a MouseListener?

Or do I have to recognize gestures in my application, possibly with the help of a library like MT4J?

Since I just started to get acquainted with this stuff, I appreciate any hint or help.

I haven't tried yet, but note that JavaFX also supports GestureEvents such as RotateEvent, ScrollEvent, SwipeEvent, ZoomEvent and probably(?) also custom events.
