EventListeners class
Hello All, I am learning ActionScript 3.0 A simple question for you. In my Actions panel. I am trying to get a video feed from the Camera. How do i you use addEventListeners to see if the feed is successfull or unsuccessfull?
copy and paste the code you are using to retrieve the feed.

How to block execution of event listeners
Hi all,
JDev version : 11.1.1.6
My requirement is that I want to block all event listeners like ActionListeners, SelectionListeners, DisclosureListeners, RowDisclosure listeners when the screen is opened in readonly mode.
I could block ActionListeners by disabling command links and command buttons etc.
But there's no way to block SelectionListeners, DisclosureListeners, RowDisclosure listeners.
So Is there any common code which can block all listeners?
Or is there any EventController or something like that which will allow me to control event execution?I would have if it was just one screen.
There are hundreds of screens.
Anyways, can't I use any javascript to do this? There are some interfaces like EventListeners , classes like EventConsumer etc. Do none of them provide feature to block event listeners? -
Handeling EventListeners given from other classes...
Hello again,
I got the folloing Problem:
I've got a Frame-Class, with calls a Class from jPanel, this Panel has a button.
My Problem is this, Is there a way, to handle the button-event from the Parent-Frame?
Means this:
MyPanel mp = new MyPanel();
this.add(mp);
// Here to wait for the button event, and do something.
If anybody has a solution, thx alot.don't expose the hour variable at all.
have a method eg addToHourBy( int hrs )
Probably a simple questions, but how can I access a
variable from another class. My exact situation is as
follows.
A class called WorldCalender has a variable which is
defined: public int hour; (the value is given to it
elsewhere).
I want to access this variable and increase it by one
in a subroutine in the class Hour. In this class I
have put: WorldCalender.hour++; but it doesn't seem to
work. How should I do it? -
EventListeners, bindingUtils, garbageCollection and you...
Hey everyone,
I hope somewhere can help me with this, because I have been
running in circles on this. I am developing on a fairly large
application and have recently noticed that instances of my class
that have event listeners of data binding tied to them cannot be
garbage collected. It has led to some fantastically bizarre
artifacts and some gross memory leaks. Multiple copies of screens
modifying and accessing the same array collections and such...fun.
The way I see it, there are three real solutions here...
1.) dictate that all programmers declare weak references when
creating event listeners
2.) create some sort of onDestroy method that kills bindings
and removes eventlisteners when a child is removed from it's parent
3.) override the addEventListener method to ensure that weak
references are made, when people inevitable forget #1!
My questions are thrice: are those my only options?! Or have
any of you more experienced folks conquered this situation in a
more elegant, reliable way? If these are my only options, which is
the best, in your opinions?
Thank you very much for any info you can give; I'm relatively
new to Flex and while I understand the GC's terms and conditions,
I'm hoping there is some way to avoid a massive rewrite/refactoring
to make it work with me. Thanks again!

There aren't any easy answers, but this might point you in
the right
direction:

Keep in mind that any event listeners added within the scope
of a component
will be destroyed when the component is destroyed.
so this.addEventListener=OK
that.addEventListener=may not be

Is it possible to pass parameters through eventlisteners?
Hello everyone!
Inside a .fla file I have some buttons and each button will tween a different image to the stage. All the images are outside the stage in the same x and y position and I just need to tween the x coordinate.
Now I'm working with an external document class where I'm trying to hold all my functions and I'm stucked with the Tweens. I'm willing to stay away from the flash tween engine and I'm trying to work with tweenLite.
My question is: Is it possible to pass parameters through eventListeners so I can use something like this inside my docClass?
public function animeThis (e:MouseEvent, mc:MovieClip, ep:int):void { //ep stands for endPoint.
TweenLite.to(mc, 2, {x:ep});
If this is possible, how am I supposed to write the listeners so it will pass the event to be listened for AND those parameters? And how to build the function so it will receive those parameters and the event?
If this is not possible, what's the best approach to do this?
Thanks again!So, I understand you need to match buttons with corresponding visuals.
Here is a suggested approach.
Since SimpleButton is not a dynamic class, I suggest you have an enhanced base class for these buttons that extends SimpleButton. What is enhanced is that button has reference to the target.
I wrote code off the top of my head and it may be buggy. But concept is clear:
This is base class for all the buttons:
package
import flash.display.DisplayObject;
import flash.display.SimpleButton;
public class NavButton extends SimpleButton
public var targetObject:DisplayObject
public function NavButton()
Now, this is your doc class that utilizes this new buttons:
package
import flash.display.DisplayObject;
import flash.display.MovieClip;
import flash.display.Sprite;
import flash.events.Event;
import flash.events.MouseEvent;
public class DocClass extends Sprite
private var btnArray:Array;
private var visuals:Array;
// references to objects being swapped
private var visualIn:MovieClip;
private var visualOut:MovieClip;
public function DocClass()
if (stage) init();
else addEventListener(Event.ADDED_TO_STAGE, init);
private function init(e:Event = null):void
removeEventListener(Event.ADDED_TO_STAGE, init);
// buttons and MCs shouldn't be in the same array - otherwise it is counterintuitive
// assuming all the objects are on stage
btnArray = [price_btn, pack_btn, brand_btn, position_btn];
visuals = [g19_mc, g16_mc, g09_mc, g04_mc];
configObjects();
private function configObjects():void
var currentVisual:MovieClip;
var currentButton:NavButton;
for (var i:int = 0; i < btnArray.length; i++)
currentVisual = visuals[i];
// hold original positioin
currentVisual.hiddenPosition = currentVisual.x;
currentButton = btnArray[i];
// set target MC
currentButton.targetObject = currentVisual;
currentVisual.addEventListener(MouseEvent.CLICK, placeObject);
currentButton.addEventListener(MouseEvent.CLICK, placeObject);
private function placeObject(e:MouseEvent):void
// if NavButton is clicked - make new visual targeted for moving in and currently visible object subject for moving out
if (e.currentTarget is NavButton) {
visualOut = visualIn;
visualIn = NavButton(e.currentTarget).targetObject;
else {
// otherwise - move visual out
visualOut = visualIn;
swapVisuals();
* Accompishes visuals swapping
private function swapVisuals():void {
if (visualIn) TweenLite.to(visualIn, .3, { x:0 } );
if (visualOut) TweenLite.to(visualOut, .3, { x:visualOut.hiddenPosition } ); -
I've been working on a bit big project. I've some components on the stage. There are basically 4 frames. Each frame has some components. What I've done is, I've used tween class. Workflow is something like this:
Frame 1:
--used Tween class to get fade effect for List component.
--used Tween.MOTION_FINISH event to fire an event when it is finished.
--when it is finished, applied eventListener
--on Change event, remove eventListeners and use Tween class again to get reverse fade effect.
--again used Tween.MOTION_FINISH event to fire an event when finished.
--in that evenHandler, gotoAndStop(2);
Frame 2:
//similar
Frame 3:
//similar
and so on.. now, what happens, is, if i play with my scene, sometimes tween class failed to work. sometimes it does not display List component, sometimes it displays List component with alpha 0.2. sometimes it happens with movieClip also. Is it flash bug or problem with my code?probably a coding problem. the most common error that seems like a flash bug would be to define a tween within a function body allowing flash to gc that tween, possibly before it starts and/or completes.

Inheritance problem: base class does not see stage instances
I'm writing a series of Search windows for an application. I create the FLA files on the stage, each has 3 simple buttons: next_btn, prev_btn, and close_btn. Those all have event listeners which call findNext(), findPrev() and closeWin() respectively. Each search window looks for different things, some with a text box and some with a combo, etc.
So I have a base class com.search that extends Sprite and adds the eventListeners at startup (actually, on addedToStage). Like this:
function isAddedToStage(evt:Event){
next_btn.addEventListener("click",findNext);
prev_btn.addEventListener("click",findPrev);
close_btn.addEventListener("click",closeWin);
Then I write the appropriate find functions in each derived class.
For example, I have
package com {
import com.search;
class searchText extends search {
In my FLA file, I set the class to com.searchText.
But when I compile and run the window, I get runtime errors:
ReferenceError: Error #1065: Variable next_btn is not defined.
at com::search()
at com::searchtext()
If I add the event listeners in the derived class rather than the base, it works fine. But that seems to defeat the purpose of inheritance, plus it infers that I won't be able to derive new classes/swfs from those derived classes.
So the question is, how does one reference objects created on the stage from a base class of that document's class?Found it. After messing around with trying dynamic classes and overriden functions that returned the desired button (that worked, but was ugly.)
Simply and silly once you know how.
You have to explicitly reference the stage objects (or any newly declared methods or properties) in the derived class as members of "this" in the base class - so:
class Search {
function isAddedToStage(evt:Event){
this.next_btn.addEventListener("click",this.findNext);
this.prev_btn.addEventListener("click",this.findPrev);
this.close_btn.addEventListener("click",closeWin);
function closeWin(e:Event){
and then create the buttons on stage in the FLA using the derived class.
You can also declare the event handling functions in the base class as empty functions and then override them in the derived classes. Or fill in the functions in the base class to throw a runtime error, and then override - that's as close to an abstract class as you can get, I think. -
I am continuing work with custom classes and OOP. I find that
I can't get eventlisteners and other actions to work unless I use
nested functions (which I know are frowned upon). The following
works correctly but the mouse event listener is an example nested
functions mentioned above. How can I rewrite this without the
nested function that executes the mouse listener? Thanks as always.

I think I should filter the list putting a string before any numerical code. -
Lose MouseEvent after creating new class. Why?
I have a main class that generates three clickable textfields (lessons). Clicking a specific lesson starts the appropriate lesson. However, once the lesson starts, I am unable to detect any mouseevents. I do not use any mouseevents in any of the lessons so I am baffled about what happened to my mouse eventlisteners. Even though I can see the nextLesson button, nothing happens when clicked. If I click it before starting my lesson, my trace indicates that I have clicked it. Any ideas? Do I need my lessons to somehow self-terminate when done and if so, how would I go about this. I currently use the browsers back arrow to terminate the complete session. Seems kludgey.
Site: itonlytakes1.org
Currently I only have one lesson published: Discover the first ten number labels. A minor annoyance is after you click on the lesson text, you have to click on the window again BEFORE the lesson will detect a numeric keypress (don't understand this either). After executing the forty experiments (around two minutes), a summary of the time it took to recognize (subitize) the dashes and the quantity of errors will display. I have been unable to create buttons or execute any code that will let you exit this screen and return to the main program screen, hence the advice to use the browser's back arrow. SO, I decided to create a higher level script that contains all the lessons instead of using HTML, but I have not published it because I can't get the mouseevent to occur after starting Labeling. I'll attach my prototype main program, Discovery, and the first lesson, Labeling (which is currently executed when you click on "Discover the first ten number labels".) Be kind as I only started using AS3 and O.O.P. in January. Thirty years ago I programmed in Fortran IV, and I haven't even written a shell script for 15 years.

var stageRef:Stage;
then later: stageRef.stage.addEventList.....
What am I missing or not understanding?I cannot get it to work. Here is my code:
package com {
// core
import flash.display.MovieClip;
import flash.display.Stage;
// import custom classes
import com.main.BuildStageClass;
import com.main.BootClass;
import com.utils.RotateClass;
import com.utils.ZoomClass;
import com.utils.PanClass;
import com.main.HotSpotClass;
// initialize class
public class DocClass extends MovieClip {
// custom classes
// variables
public static var build_stage_class:BuildStageClass;
public static var boot_class:BootClass;
public static var rotate_class:RotateClass;
public static var zoom_class:ZoomClass;
public static var pan_class:PanClass;
public static var hot_spot_class:HotSpotClass;
// stage containers
public static var main_stage:MovieClip;
public static var background_layer:MovieClip;
public static var content_layer:MovieClip;
public static var popup_layer:MovieClip;
// main constructor
public function DocClass() {
// initialize classes
build_stage_class = new BuildStageClass();
boot_class = new BootClass();
rotate_class = new RotateClass();
zoom_class = new ZoomClass();
pan_class = new PanClass(this.stage);
hot_spot_class = new HotSpotClass();
// add containers to stage
main_stage = new MovieClip();
addChild(main_stage);
background_layer = new MovieClip();
main_stage.addChild(background_layer);
content_layer = new MovieClip();
main_stage.addChild(content_layer);
popup_layer = new MovieClip();
main_stage.addChild(popup_layer);
==========================
Now inside the pan class:
package com.utils{
// import classes
import flash.display.MovieClip;
import flash.display.Stage;
import flash.events.MouseEvent;
import flash.geom.Point;
import flash.ui.Mouse;
// import main classes
import com.DocClass;
// initialize class
public class PanClass extends MovieClip {
// variables
public var do_pan:Boolean = true;
public var last_point:Number = 0;
public var cur_point:Number = 0;
public var hand_cursor:HandCursor;
public var grab_cursor:PanCursor;
private var myStage:Stage;
// main constructor
public function PanClass(docClassStage:Stage) {
// constructor code
myStage = docClassStage;
myStage.addEventListener(MouseEvent.MOUSE_MOVE, panHandler);

Hi,
is there any class in Java to handle keybord shortcuts?
E.g. I have a following part of code:
JPanel panel = new JPanel();
getContentPane().add(panel, BorderLayout.NORTH);
panel.setLayout(new FlowLayout(FlowLayout.LEFT));
JButton button = new JButton("Some stuff");
panel.add(button);
button.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e) {
if(!isModified) {
resetGrid();
readData();
I need that button to respond even if I press CTRL+R on my keybord for instance. Is there such a class, or do I have to handle that with some EventListeners?
Thanks in advance. Lokutus.This is usually solved with the Actions framework.

But the problem both java classes for I used one Jsp only Dynmic spoof customer will come from the JSP Input filed.
In the new Java Class How can I capture the Event When I click the Buttong the InputField value capturing into the AbstractPortalcomponent Class.
I tried like this but It comes as Null Value.
Event event = myContext.getCurrentEvent();
if(event!=null)
InputField ip= (InputField) myContext.getComponentForId("spoofCust");
String spoofCust=ip.getValue().toString();
Please suggest me in this.
What is wrong with this.
Thanks,

Lohitha MLohitha,
Try replacing your two lines of code:
InputField ip= (InputField) myContext.getComponentForId("spoofCust");
String spoofCust=ip.getValue().toString();
with:
InputField ip = (InputField) getComponentByName("spoofCust");
String spoofCust = ip.getValueAsDataType().toString();
Let me know how that works for you.
