Hi,
Thanks for your replies, it confirms what I was thinking... The iOS way of
sending events seems to be an exception, all the touch technologies I use
(mostly MPX, Windows 7 and TUIO) send them separately, so I think it should
be useful to add to EventQueue a way to track the events to put them
altogether into the GUIEventAdapter, what do you think ?
Cheers,
