Actionscript 3 :: Flex 3 Customevent Not Getting Dispatched?
Feb 6, 2010
I have a function called DrawPlaybook which listens to two events, one mouseclick event and one custom event.
public function DrawPlaybook(...):void
{
panel.addEventListener(MouseEvent.CLICK,[code].....
I am planning to call the custom event from within "onClickHandler" like this:
public function onClickHandler(e:MouseEvent,panel):void {
var eventObj:CustomPageClickEvent = new CustomPageClickEvent("panelClicked");
eventObj.panelClicked = panel;[code].....

I am trying to listen to an event created in a spark popup tileWindow. The aim is to get an array sent and updated in the popUp, to be received by the calling application, when the popUp is closed. As commented inline below, I have tested that it reaches the point of dispatching event in the popUp- and never gets listened in main application. What am i missing?My customEvent is as follows:
package folder1
{
import flash.events.Event;

I'm testing some event dispatch code in a Flex app, using FlexUnit's addAsync method for testing that events are dispatched. Great so far, I can ensure that at least one event was fired. However, I want to be a bit more detailed; I want to ensure that exactly the set of events I'm expecting are dispatched. Is there a useful test pattern (or, even, different test framework -- I'm flexible!) to accomplish this?I tried this code, but it doesn't seem to get invoked the second time:[code]

I have a text area on which I would like to listen to change events when I change the text formatting using setFormatOfRange(). So far all other events I have tried, such as Event.CHANGE or TextOperationEvent.CHANGE are only dispatched when the actual text is changed.
Anyone know what I should be listening for ?

I am trying to determine what events I need to wait for in a test in order to ensure that my custom component has updated all of its properties. I was using VALUE_COMMIT, but for some reason that isn't working out for me. I want some easy mechanism for tracing every event dispatched from a component. Is this possible?

I want to know when the data has been added to a chart so I can use localToData() to draw on the chart. If I do this immediately after setting the dataProvider the chart has not yet updated, so the the call to localToData will not return the correct values. Is there an event I can subscribe to so I know the chart has drawn the data in the dataProvider?

I'm using an accordion container that has it's creation policy set to auto. One of the accordion's children is a spark border container that has a data grid within it. Currently, I'm using the data grid's creationComplete property to call a function; similarly, I'm using the dragComplete property to call another function.
How can I add listeners for events (creationComplete & dragComplete) via actionscript? The obvious problem is that the accordion does not create all its children on creation (nor do I want it to), so I can't simply use something like: datagrid.addEventListener(...)

I tried to send some services to fetch data in the creationComplete handler. Then I need to process the server raw data before displaying some sub components. Where should I put these kind of code?

I'm having the following problem: I've implemented a custom headRenderer for my DataGridColumn. The idea is to have a dropdown menu when clicked on the column header. The problem is I don't know how to add a listener or pass a variable to the renderer since the renderer class is instantiated by the ClassFactory.
The renderer class:

I'm working on implementing communication between an Adobe AIR app and a browser Flash object, and the LocalConnection documentation mentions an asyncError as a potential event:
asyncError: Dispatched when an exception is thrown asynchronously — that is, from native asynchronous code.
However, that's the only documentation I can find on it. Does anyone know what this error actually means? I've searched around but couldn't find any reference -- most sample code I found does an addEventListener() for the asyncError but doesn't give any clue as to what it means or when it could occur (i.e. if it could occur when sending or when recieving).The Adobe documentation page also lists potential events for each method, but asyncError isn't listed under any specific method, only for the general class.

I am currently working with a drawing tool for a mapping API, and every time I double-click the mouse a map service will perform a measurement and display the length of the line that I am drawing.
I want to mimic this double-click manually by dispatching a MouseEvent.DOUBLE_CLICK, but the map service is not listening to this default Flex event. I suspect that the API has created a custom MapMouseEvent or something like it that is being dispatched when a user double-clicks the mouse.
Is there a way to determine which event is being dispatched when I double-click the mouse?

I have the following situation:I have an event handler, that displays small messages in my application's statusbar.These messages get passes through by dispatching events from custom components.A simple message could be like "HTTP Error" or so.Now, the main event listener, in the main application file, listens to the event dispatched by any custom component,but seems to refuse listening to events dispatched by custom AS classes.Here is my code for the custom event:
package main.events
{
import flash.events.Event;[code]..
So to sum it all up:
- The event listener listens to the custom event dispatched by any custom component.
- The event listener does not listen to the custom event duspatched by an AS class.
Those who wonder, the event really gets dispatched, that's why I added a trace call.

My friend recently said, that you should find some way without "CustomEvent" if you wanna follow OOPs strictly. Is this true ? Is this the reason, that such class is not provided by Adobe natively ? In many of my projects, i find it impossible to communicate without being able to send information via parameters. Is using "CustomEvent" like thing, a breach into OOP rules.

I am really confused at the moment, need help using the accelerometer class and event with AIR 2.5 on mobile devices (Android). I have looked at many sources and the process is fairly easy. I just don't understand why my event is not being fired in both of my devices i'm using for testing. This being the first time I actually decided to test out the AccelerometerEvent, resulted in a total Fail.

i am having trouble understanding how to dispatch events and where to catch them. currently i have a document class waterMain, and another class called gunner. my waterMain createds a object of gunner and adds it as child, in my gunner there is a function firebullet, in it i dispatch a
dispatchEvent(new Event("bulletFired"));
and from my waterMain class i do a
addEventListener("bulletFired", bulletFiredHandler);
private function bulletFiredHandler(e:Event):void
{
hudMenu.reduceBullet();
}
the hudMenu is a variable on the waterMain document class, however it seems that nothing is happening. is the waterMain class not catching the dispatched event?

import flash.display.MovieClip;

I have an application which uses web services. One day when everything was working fine,suddenly no web services were getting called.I went on debugging the code.After spending almost an hour i figured out that wsdlLoadEvent of WebService class was not getting dispatched. It is the same event in which webservice gets ready (ready property of a web service is set to true) to be called.So none of my web services were getting called. I don't know how this happened.

I'm getting this weird glitch where the added_to_stage event seems to be dispatched twice when I construct my object.Now I know that my constructor is not being called twice cause I traced a string before the event listener, and it only traces once but I traced the same string within the listener handling function body and it traced twice.
Here's the code:
Code:
package com.berubegraphics.martinemartell
{
import flash.display.MovieClip;
import flash.display.Sprite;

I am an AS3 code developer but this time I need to deal with a FLA that has an instance on timeline with complex nesting of movieclips and textfields (that are named via the instance field in Flash). The problem is that events (I put in the Documentclass) on nested movieclips inside that timeline placed instance are never dispatched.
Example code:
// my instance on Stage in all Frames of the timeline
public var thewall:MovieClip;
// event directly on thewall works
// the event is dispatched correctly
thewall.addEventListener(MouseEvent.CLICK,click);
[Code] .....
How do I have to access them to get the Events dispatched?

Let's say you have a guestbook in where you constantly update the data pulled from a .txt file, but when someone posts a comment and press the SUBMIT button, you'd like that the data is updated at that moment to make it display faster, but since an already dispatched event is coming to update the data of your guestbook WITHOUT the newly posted comment, a flicker might occur, so you would then like to stop that data from being transferred to your Flash file and rather dispatch a new event to load new data with your recently posted comment. Or maybe you just want to know how to stop an event from any class, either way, you've come to the right place.
Let's use that guestbook as our example. Instead of using an onEnterFrame to constantly update the data, I'd use LoadVars' onData event to retrieve the data, but when that data has been transferred, dispatch another onData event, and make this keep going in a loop:
ActionScript Code:
function updateGuestbook(){
loadData = new LoadVars();
loadData.onData = function(data){
[code]...
and then I have this button to submit my comment to the guestbook (keeping it simple):
ActionScript Code:
submit_btn.onRelease = function(){
loadVariablesNum("somefile.php", 0, "POST");
updateGuestbook();
}
so I call the updateGuestbook function, which will fire another event to load new data, but another event has probably already been fired off already with the old data, and this will cause the guestbook to nudge a bit, flicker, if you know what I mean, because first the old data will load, then right after that, a few milliseconds later, the new data will load, and this will be visible to the eye, and will probably not look good.What you can do, is to stop the previous event, delete it, to stop its data from being received by Flash. To do this, simply use this:
ActionScript Code:
delete loadData.onData;
to delete that event, just as simple as that.
ActionScript Code:
submit_btn.onRelease = function(){
loadVariablesNum("somefile.php", 0, "POST");

How would I check if an event has already been dispatched or not?
Is it as simple as checking the "target" property if it's null or not? Or are there cases when the target will be null, but it still has already been dispatched?
