Double tap in webOS

How can I implement DoubleTap event 开发者_如何学运维and SingleTap event separately in webOS ?

In your handler for Mojo.Event.tap, look at the event's count field. That will be 2 for a double-tap, 1 for a single-tap. Note that you'll always get the single tap first, so make sure you don't do anything destructive on that.
