using the following code i cant get a cancelled event phase

if i touch the object i get began, if i move i get moved, if i let go i get ended.

what action would generate the cancelled phase

local bb = display.newCircle( 200, 100, 30 ) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; bb:addEventListener("touch", function(e) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if e.phase == "began" then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; print("began") &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; display.getCurrentStage():setFocus( e.target ) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; end &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if e.phase == "moved" and e.target.isFocus then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; print("moved") &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; end &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if e.phase == "ended" then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; print("ended") &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; display.getCurrentStage():setFocus(nil) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; end &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if e.phase == "cancelled" then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; print("cancelled") &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; display.getCurrentStage():setFocus(nil) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; end &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; end)

What if you drag offscreen? If I remember correctly from a post I read, that caused a cancelled event. But I could be wrong.

If I remember correctly, a cancelled event is generated when an orientation change occurs while touching an object.

It also occurs if you’d do a four-finger swipe up or left/right on an iPad while an object is “active”.

jstrahan,

Did you see this from the other thread you posted in about the detecting if the user had moved off an object? It is a note from Brent at Corona:

“cancelled” is not really an event that gets triggered by the user. It generally happens only if the OS itself cancels the process, i.e. something interrupts the process.
