local inc_btn = ui.Button(win, "Increase Label.height !", 15, 10)
local dec_btn = ui.Button(win, "Decrease Label.height", inc_btn.x+150, inc_btn.y)

label.fontstyle = { bold = true }

function inc_btn:onClick()
	local delta
	if self == inc_btn then
		delta = 10
	else
		delta = -10
	end

end

dec_btn.onClick = inc_btn.onClick

-- shows the Window
win:show()
