WebOS co-ordinates of a finger drag.

Question

I'm trying to find out what the co-ordinates of a users finger when they slide it around the screen.

So in otherwords, if the users taps the screen in the far left corner and drags their finger, without lifting it from the screen, to the borrom right corner; I want to know the full set of co-ordinates.

Would it just be via the down method of Mojo.Event.tap?

Many thanks.
