I am having trouble with the controls showing up for my transform tool. When I click my image I get the bounding box (to scale or rotate the image), but when I hover over the corner I do not get the cursor to transform it.
I am using these files:
This is my code to call the transform tool:
var tool:TransformTool = new TransformTool();
addChild(tool);
And this later on to make the tool show up when the image is clicked and make the tool disappear when the stage is clicked:
tmpImage.addEventListener(MouseEvent.CLICK, select);
function select(e:MouseEvent):void {
tool.target = e.currentTarget as S
stage.addEventListener(MouseEvent.MOUSE_DOWN, deselect);
function deselect(e:MouseEvent):void {
tool.target =
tmpImage.addEventListener(MouseEvent.CLICK, select);
My image selection for the bounding box to appear and disappear work perfectly. All my code works as expected.... except the actual controls on the bounding box. Please help!
The concept is the user can click an image from a menu and drag a new instance of that image to the stage. Then the user can click the new instance and should be able to rotate or scale it. Then they can click off the image to make the bounding box disappear.
(They can add as many images to the stage that they want).
Here is some code that shows the basic click, create new instance, and drag process I have implemented.
//sb1 is the menu area that contains a group of images
//hill is one of the images the user can add to the stage
sb1.hill.addEventListener(MouseEvent.MOUSE_DOWN, createCopy);
var i:int=0;
var tmpImage:S //to store which image is being dragged currently
function createCopy(e:MouseEvent):void {
tmpImage = new Hill_mc();
tmpImage.name = "hillChild"+(i++); //increment every copy
container.addChild(tmpImage);
tmpImage.x = mouseX-470;
tmpImage.y = mouseY-270;
tmpImage.startDrag();
tmpImage.addEventListener(MouseEvent.MOUSE_DOWN, onDown); //add the mouse down to this new object
stage.addEventListener(MouseEvent.MOUSE_UP, onUp); //since the mouse is currently down, we need to listen for mouse up to tell the current copy to stop dragging
//this will be called when click a copy
function onDown(e:MouseEvent):void {
tmpImage = Sprite(e.currentTarget); //get a reference to the one that was clicked, so we know which object to stop dragging on the global mouse up.
container.addEventListener(MouseEvent.MOUSE_UP, onUp); //listen for the mouse up
tmpImage.startDrag();
function onUp(e:MouseEvent):void {
container.removeEventListener(MouseEvent.MOUSE_UP,onUp);
if (tmpImage.hitTestObject(thesubmenu1)) {
container.removeChild(tmpImage);
tmpImage.stopDrag();
tmpImage.addEventListener(MouseEvent.CLICK, select);
function select(e:MouseEvent):void {
tool.target = e.currentTarget as S
tmpImage.addEventListener(MouseEvent.MOUSE_DOWN, deselect);
function deselect(e:MouseEvent):void {
tool.target =
tmpImage.addEventListener(MouseEvent.CLICK, select);
I found this code and placed it in my TransformTool.as. I feel like it's so close and that there must be something called incorrectly because I get an error for a null object reference:
public function select(event:Event):void {
// the selected object will either be the
// event target or current target. The current
// target is checked first followed by target.
// The parent of the target must match the
// parent of the tool to be selected this way.
if (event.currentTarget != this
&& event.currentTarget.parent == parent){
setTarget(event.currentTarget as DisplayObject, event);
}else if (event.target != this
&& event.target.parent == parent){
setTarget(event.target as DisplayObject, event);
* Helper selection handler for deselecting target objects. Set this
* handler as the listener for an event that would cause the
* deselection of a target object.
* It is not required that you use this event handler. It is only a
* helper function that can optionally be used to help ease
* development.
public function deselect(event:Event):void {
if (_target != null && event.eventPhase == EventPhase.AT_TARGET){
setTarget(null, null);
You give too little information to determine what exactly is wrong.
However, there is a very good sample code that does exactly what you want here :
(Click on the link at the bottom of the image.)
I am sure that you are going to make it with this.
Try to use the built-in handlers. I would do something like this :
Instead of this :
tmpImage.addEventListener(MouseEvent.CLICK, select);
function select(e:MouseEvent):void {
tool.target = e.currentTarget as S
stage.addEventListener(MouseEvent.MOUSE_DOWN, deselect);
function deselect(e:MouseEvent):void {
tool.target =
tmpImage.addEventListener(MouseEvent.CLICK, select);
tmpImage.addEventListener(MouseEvent.MOUSE_DOWN, tool.select);
stage.addEventListener(MouseEvent.MOUSE_DOWN, tool.deselect);
If you do not have the handlers, I am not sure :) but I would recommand removing event listeners in each method as they might be interfering with each other.
tmpImage.addEventListener(MouseEvent.CLICK, select);
function select(e:MouseEvent):void {
tmpImage.removeEventListener(MouseEvent.CLICK, select);
tool.target = e.currentTarget as S
stage.addEventListener(MouseEvent.MOUSE_DOWN, deselect);
function deselect(e:MouseEvent):void {
stage.removeEventListener(MouseEvent.MOUSE_DOWN, deselect);
tool.target =
tmpImage.addEventListener(MouseEvent.CLICK, select);

Tools yet to be developed
We're constantly working on updates and new features. Here's a small preview of things to come!
MIMOA WIDGETS
Soon to be developed: integrate MIMOA content on your website.
MIMOA CITY INFO
Soon to be developed: . We will assemble all necessary, interesting, hard to find, undisclosed information which you can not find in the 'main stream tourist guides', and conveniently orden this information for every major architectural destination. All user generated info, off course.
Add Rich Point Of Interest to TomTom
With this feature you'll be able to add several projects onto your TomTom device & all at once. Download your Mi guide or other selections of projects that you want to visit. Your TomTom will show these Points of Interest (POI's) with images and accompanying text (description, opening hours, etc &), aside from lat-long coordinates.
Perfect for your architectural excursion, and what's more: the route between the POI is automatically complemented by whatever TomTom information you normally get along the way. Such as traffic, weather, safety cameras and more.
