buttonB:setDimensions(64, 48)
buttonB:setPosition(150,150)
buttonB:setText("btn2")

stage:addChild(buttonA)
stage:addChild(buttonB)

--Here we put the WidgetAction listener on stage. 
--It will be propagated from each button up to stage through the sprite tree
--First parameter of event listeners are always the source widget of the event
function stage:onWidgetAction(w)
	if w==buttonA then
		print("b1")
	elseif w==buttonB then
		print("b2")
	end
end

A button with repeat on 

UI.Style:setDefault(UI.Theme.PointCore_Pink)

local gui=UI.Button.new({ Repeat=0.5, RepeatSpeedup=0.9, NoDoubleClick=true, })
gui:setDimensions(64, 48)
gui:setPosition(128, 128)
gui:setText("btn")
gui.name = "button"

stage:addChild(gui)

function gui:onWidgetAction(w)
	print(w.name, "clicked")
end

A button with a long click indicator 

UI.Style:setDefault(UI.Theme.PointCore_Pink)

local gui=UI.Button.new()
gui:setDimensions(64, 48)
gui:setPosition(128, 128)
gui:setText("btn")
gui.name = "button"

UI.Behavior.LongClick.new(gui,{ clsIndicator=UI.CircularProgress, szIndicator=24 })

function gui:onWidgetAction(w)
	print(w.name, "clicked")
end

function gui:onWidgetLongAction(w)
	print(w.name, "long clicked!")
