local cf= CompositeFont.new{ -- *** PLEASE NOTICE THE CURLY BRACES { } INSTEAD OF ( ) ***
	{ font=of, color=0x0, alpha=1, }, -- draw outline in black
	{ font=nf, x=1, y=2, }, -- draw normal text with an offset
}
local tf = TextField.new(cf, str)
tf:setTextColor(0xff0000)
tf:setPosition(16, 64)
stage:addChild(tf)
