I'm trying to call an event I've created in another component. I've added trace() into my methods so I can see what's being called. Everything except for the event listener (myEvent) is being called.

So I have an object, generated on each click of the mouse. It's set up as a series of points with properties, with values for position randomly calculated, and set around where the user clicks the mouse. Lines are drawn from where the mouse is clicked out to each of these points, so it kind of looks like a star, but only lines, rather than a solid shape (like those old 50's atom clocks?). So once clicked there's an enter frame event listener on the object so that each of the points 'wobble' (using a randomly generated number) up and down around the original point.
For some reason, I can either set it so that on each new click of the mouse and newly generated object, the last one stops "wobbling" and only the new one does, or each new object moves to where the new object is, and maybe is still wobbling(?), but is underneath the new object. This way has the event.target as a new object in the wobble function, so I think it may be just a case of where the centre point is - i.e. saving the mouse x and y for each object individually, or perhaps I have too much of the setup function code repeated in my "wobble"function?

I've dynamically created event listeners in the usual sort of way:
Code:
myText.addEventListener(MouseEvent.MOUSE_OVER, hover(nameLabel));
function hover(nameLabel):Function
{
[Code].....
The problem is how to remove the event listener later in the program as the usual code isn't working. I'm guessing I should have done this in a class but I'd like to understand this problem better.
printableInvoice.addEventListener(batchGenerated, printableInvoice_batchGeneratedHandler);Results in this error: 1120: Access of undefined property batchGenerated. I have tried it as FlexEvent.batchGenerated and FlashEvent.batchGenerated.
The MetaData and function that dispatches the even in the component printableInvoice is all right. It I instantiate printableInvoice as an mxml component instead of via action-script it well let put a tag into the mxml line: batchGenerated="someFunction()
So, I'm trying to load resources, add them to a dictionary, and have a drawing method search through that dictionary and draw based on certain predicates. I have a function that iterates through an Vector of Strings, calling on an instance of Loader to load them instantiated as a URLRequest.
private function loadImages(urls:Vector.<String>):void
{
var loader:Loader = new Loader();
[Code].....
So the issue is: Only the first images in my Vector are drawing. Upon further inspection, I found that the completeHandler was only being called once (I put a trace in the complete handler to check). However, the Loader is invoking load everytime the loop iterates. I tried instantiating separate loaders for each resource, just to see if it would work, but I had no luck with that. Do I need to make separate loaders and event handlers? Or am I just not using Loader correctly?
I need to call FileReference.save() after a web service call has completed, but this method has a restriction: "In Flash Player, you can only call this method successfully in response to a user event (for example, in an event handler for a mouse click or keypress event). Otherwise, calling this method results in Flash Player throwing an Error exception." (from the documentation here)
This restriction is a bit vague. Does it mean that I can only call the FileReference.save() method from within an event handler function that is registered as a listener for certain types of user events? If so then exactly which user events are valid? (Perhaps there's an event that will never be dispatched by user interaction with my application and I could register an event handler function for that event type and make the save() call from within that function?)
My difficulty is that I can't safely call the FileReference.save() method until my web service returns with the data that will be used as the argument of the FileReference.save() method call, so the event that triggers the FileReference.save() call is actually a ResultEvent rather than a user event, and I'm leery of dispatching a new (faux) user event type in order to be able to trigger the FileReference.save() call unless it's definitely a user event that would never be dispatched as a result of actual user interaction with my application.
In a nutshell what I'm doing now is this: I have a function that is registered as a handler for a button click. In this function I make my web service call to fetch data from the server. I also have a result handler function which gets invoked when the web service call completes, and it's in here that I want to call the FileReference.save() method since it's at this point that I know that the data is ready to be saved to a file. But the aforementioned restriction is blocking me from doing this -- I get an error:
Error #2176: Certain actions, such as those that display a pop-up window, may only be invoked upon user interaction, for example by a mouse click or button press.
I've tried many things to get around this such as creating a second mouse click event handler function with the FileReference.save() call within and calling it after a timeout interval (to give the web service time to complete), but I keep running into the same error -- maybe that approach doesn't work since the second function isn't registered as an event listener for the event type used as its argument.
I'm trying to sync animation to music at a specific BPM. I've tried using the Timer but it isn't accurate when dealing with small intervals in milliseconds. I did some reading and found an alternate method that uses a small silent audio file and the SOUND_COMPLETE event as a Timer.[code]...
View 4 RepliesI got a reference to an arrayCollection and add event listener like this:
collection.addEventListener(CollectionEvent.COLLECTION_CHANGE, onCollectionChange);
That's fine. Now some other component does have the same reference and is adding items to and removing items from that collection.
Each time the handler is called:
private function onProjectPersonsChange(event:Event):void {
if (event.kind == CollectionEventKind.ADD) {
//do something
} else if (event.kind == CollectionEventKind.REMOVE) {
[Code] .....
Why the removed item is not in 'items'?
In our app, I am periodically noticing that a particular event handler is not firing. 99% of the time, it works fine, but, every so often, it just dies. How can I find out whats happening? Is the DispatchEvent() not happening/working somehow? Is my listener still listening? Did something else catch the event, and not pass it along so that the 'right' listener can get to it ?
Here's a little bit of the code...
Thats a somewhat pruned down version of what the real code is, but I don't think I trimmed out anything important. The key, as I see it is that we fire up the params dialog, then start to listen for the closed event. Then, we show the param dialogs close function. What happens when it fails is that the trace message "caught close event.." is never generated, and, consequently, the closeHandler is not getting called at all.
let's say that i have this button which is called "Click_Here" and i added an event listener to it in some class file in order for it to run the event handler in a different one .. so it will be like this
classfile1.as
Click_Here.addEventListner(MouseEvent.CLICK , buttonClicked ) ;
classfile2.as
public function buttonClicked (e:MouseEvent){ trace ("hello");}
We have a flex application that connects to a proxy server which handles authentication. If the authentication has timeout out the proxy server returns a json formatted error string. What I would like to do is inspect every URLRequest response and check if there's an error message and display it in the flex client then redirect back to login screen.
So I'm wondering if its possible to create an event listener to all URLRequests in a global fashion. Without having to search through the project and add some method to each URLRequest.
this is the error I am having:

I have noticed that when I select tree node if space is clicked the selected node gets opened... how could I remove this event?
View 1 RepliesI know I can create a custom event and associate data with it and retrieve it in respective Event Listener. But What I am interested to know is, is there a short method (without having to extend Alert Event Class) to associate parameters to its alert Listener.

I want to add an event listener to each component inside a repeater, but don't know how. Here's some code I have tried:
<mx:Repeater id="rp" dataProvider="{dataProvider}" width="100%">
<mx:Button id="attach" creationComplete="addListeners(attach[rp.currentIndex])"/>
</mx:Repeater>
This doesn't work. creationComplete is not called until the repeater has finished instead of (as I expected) when the creation of the button is complete. I'm not sure how to accomplish this.
BTW - I also tried placing the creationComplete on the parent component to the repeater, but it would only be called the first time the component was rendered (the data inside the repeater sometimes changes) so that didn't work.
I am building a drag and drop application, and have most of it working. however, when I drop the drawings on the canvas, i am not able to drag them again.. even though i have given them the same drag function.
here is part of my code. i have attached the rest. any thoughts? i am very new to AS3! the bdaddedListener is running.. but the addEventListener of drag will not run

I am writing a web application that will serve as a configuration for a random data generator that I have written in Java.The values that I set in this application will write to xml. The xml data is updated by a file called simulationParams.as and that file is added to each child in the "viewStack" so that when I change any of those values the simulationConfig file will be automatically updated.The problem is that when I press the randomizeBtn the proper events are fired and the listeners grab those events.My problem exists when I uncheck the randomize button.For some reason an event is triggered or the listener isnt listening so that when I uncheck randomizeBtn the values go back to their last position or value on the slider. Ex. if my initial value is 0 then press randomize the slider will go to 100. The config file updates and all is well.When I uncheck the randomizeBtn, the sliders value goes back 0 but the config file isnt update.The same thing happens when I press the useDefaultBtn for both selected/unselected, nothing gets updated.[code]

View 4 RepliesI have a tab navigator defined in MXML, with two tabs.In each tab, I have some buttons. I have used ActionScript to add event listeners to all the buttons, and they work for the buttons that are visible (and in the currently "active" tab) when I load my Flex 4.5 AIR application.However, I get an AIR error for the event listeners attached to the buttons in the second tab.Here's the crucial part of the error:TypeError: Error #1009: Cannot access a property or method of a null object reference.
View 1 RepliesI'm trying to add an event listener to my air application that would prevent the "ActionScript error" window from appearing, so I can handle the error within my application.I was able to find a little information about this from adobe. I'm just not sure what I should be listening for.
View 3 RepliesOn my main timeline I have an empty MC that my external swf's get loaded into once a user makes his selection from the menu.I would like to tween the load in and load out of these swfs.What is the best way to go about this?Should I add a Listener to the main timeline that listens for my MC to be called? I guess the real hangup here for me is understanding how to initiate the tween on load in and load out.
View 1 RepliesI have a drop-down menu that stays open when I click it, until I click it again. I want it to close when I click away from it. So I created an event listener of type MouseEvent.CLICK and apply it to the stage.
The obvious problem is, though, that when I click the drop-down menu to make it open, I'm also clicking the stage, which prevents it from opening.
I think there's probably a simple solution to this but I'm stuck. I called stopPropagation() on the drop-down menu and that seems like it should help but it doesn't.
I have multiple items in my app that I would like the user to click on.Some items are completely different classes.The classes dispatch events and then when the events are captured, some modifications are done to the transform properties of a loosely coupled display object.I want two separate classes to dispatch the same type of event, since I already have an image class that draws images based on a given url... I want the classes to dispatch the events, but then I think I want the difference to be detected when the event comes along... i.e., I would like to recognize the 'origin' or 'sub-type' of the event. Some sort of if/then logic would suffice.
View 1 RepliesI rune the following code from TestClass:
ActionScript Code:
handler.loadFromFile("test5.txt");
dataset.generateComplete();[code]....
However, why does dataset.generateComplete(); get called before onFileLoaded(event:Event)?I can only assume that this is the case, as var pointList:Array = myHandler.getPointList(); returns Null, and when I run some tests with trace statements,I can see that onFileLoaded (event:Event) is seemingly called after generateComplete() Is the URLLoader process running in parallel to the rest of the application?
I have a Tree, which has an itemRenderer. On the itemRenderer, driven by the XML conditions, objects are created dynamically and added as a children to nodes. These new objects shall trigger an event handler ( some click events mostly ). How do I pass the event handler to the tree and later to the dynamically created new objects inside itemRendere?
Something like:
<mx:Tree x="534" y="49" newObjectsOnClick="newObjectsOnClickHandler">
I am trying to learn JavaScript and I am wondering whether JavaScript has a event listener just like ActionScript's ENTER_FRAME. Basically, I want this event listener to listen "all the time" not just wait for any particular instance (mouse click, keyboard event) of event.
View 3 Repliesif I have an event listerner (mouse, keyboard, enterframe,....event) that is being triggered, and when it finishes its event, something that is able to detect the finished event listener and fire out another sets of event.
It works more like MOTION_FINISH in TweenEvent, but it is only available for TweenEvent only, what if I want to detect a mousclick, keyboard, enterframe or even touch event?
My stage has about 25 buttons on it. Each button when pressed to tweens the background to some random x/y coordinates and then loads an external swf file.This is all working, but the timing is off. How can I wait for the initial background tween to end before I make the loader call to the .swf file.Currently each button's behavior is called on the MouseEvent.CLICK event which calls a function that knows its unique filename.swf. I know you can add the MOTION_FINISH even to the tween event but then I would have to call a new function and lose track of the button that initially called it.
View 3 RepliesI'm moving on to my next massive programming project and I'm trying to decide whether I should code it in as 2.0 or 3.0. I came across the new click event model in 3.0. Right now it's looking like a pain in the butt to me. So now I have to make a function and add it as an event listener? what the hell? What's the benefit? I understand stuff like this makes AS a more complete language but it's kinda annoying.
