Re: multi-touch capabilities

I haven't done anything with multi-touch yet but I think you would use TouchEvent for multiple touch events. And I think MouseEvent would work like your first option. But I could be wrong.

Re: multi-touch capabilities

@XoomMan, you're exactly right.  I was assuming that his comment "although my app is not specifically looking to respond to a multitouch gesture" meant he was actually listening only to the MouseEvents which are automatically generated in parallel to the touch events.


I guess if he's actually responding to TouchEvents, but not handling them properly (i.e. tracking the touchPointIDs), then he could well get behaviour unsuitable for his app.  (I'd say "unexpected" behaviour, but he hasn't describe his expectations really.)

Re: multi-touch capabilities

Thank you guys. I am using MouseEvents - and your guess at what should happen with a second 'touch' happens being ignored by MouseEvents makes a lot of sense.

Re: multi-touch capabilities







That will just report all touches as mouse events only, and disble reporting of individual touch events or gestures. It's a global setting as far as I can tell, something that Adobe will have to change sometime, because it should realy be component-specific.


The only way to test multitouch at the moment is:



  1. on Windows with a touchscreen as a stand-alone AIR app (the simulator doesn't handle touch properly, even with a touchscreen)
  2. on another platform, such as Android or IOS
  3. on a physical PlayBook 


I've used 1) on a Packard Bell Viseo 200T monitor and a Dell Latitude XT2 and 2) on an HTC Desire HD.
