AS3.0 code for tooltip

Question

Hello, I'm able to find AS2.0 code for a tooltip, but can't seem to find a simple one for AS3.0.
When the pointer hovers over a point on the map, a tooltip appears with the name of the city. I need to be able to change the city name depending on the point.
I appreciate anyone's help!

// create one buttonObj for all your buttons
var buttonObj:Object={};
//////////////////////////////////////change nothing above ////////////////////////////////////
//the next 3 lines need to be done for all your buttons
buttonObj[yourbutton.name] = ["hello",2,2];
yourbutton.addEventListener(MouseEvent.MOUSE_OVER,addToolTipF) ;
yourbutton.addEventListener(MouseEvent.MOUSE_OUT, removeToolTipF);
////////////////////////////////////change nothing below/////////////////////////
function addToolTipF(e:MouseEvent):void{
var a:Array = buttonObj[e.currentTarget.name];
var tf:TextField=new TextField();
buttonObj[e.currentTarget.name].push(tf);
tf.text=a[0];
tf.multiline=false;
tf.autoSize="left";
tf.border=true;
addChild(tf);
tf.x=a[1]+e.currentTarget.x;
tf.y=a[2]+e.currentTarget.y;
function removeToolTipF(e:MouseEvent):void{
removeChild(buttonObj[e.currentTarget.name][3]);
buttonObj[e.currentTarget.name].splice(3,1);
