With the latest code you should be getting notification of multitouch gestures as well as raw multitouch events. These events use JavaFX's built-in gesture recognizer for embedded platforms.
Out of curiosity, what touch screen are you using? Thanks, Daniel On May 7, 2014, at 12:29 PM, Daniel Blaukopf <daniel.blauk...@oracle.com> wrote: > Hi Ricardo, > > These are great questions.
