ActionScript 3.0 :: Event Dispatch With Some Additional Data
Mar 26, 2011
I have a question about eventDispatching. Now, I know how to dispatch them, and I've also grasped a minimum of custom events, enough to create one from template at least. So, say I would like to dispatch an event with some additional data, I could create a custom event class and let the event take the data objects as a parameter. But I find it a bit cumbersome to do this every time I want to dispatch data, since it results in new custom event classes. The other method I know of to get the data is to simply use the currentTarget property of the event. So if I have a getId() method for instance, I could call e.currentTarget.getId(). Now, while this works, I wonder, is it considered bad practice, and if it is, whats the right way to do it?
I am having trouble using a custom event in flex. I need to dispatch an event from inside two nested components and receive it in the main application file. The basic set up is a main application file importing a custom "gallery" component.
In my AIR application, I try to dispatch a custom event from a class to main window.This class is use to call httpservice. My goal is to send a custom window when the httpservice result is send.[code]...
The problem is I get Error: Error #2094: Event dispatch recursion overflow. Why does removechild keep getting called if this.parent does not exist? Why doesn't removing event listeners work?
I have an event listener for a custom event type. This custom event overrides the clone method as required.In this event listener I want to dispatch an instance of a different type of event... a different custom event instance altogether. It also overrides the clone method as required.The problem is I'm getting a type coercion error: TypeError: Error #1034: Type Coercion failed: ...I do not know what is trying to do the casting. My code is:
/* elsewhere in a method */ addEventListener(GestureEvent.GESTURE_SCALE, handlePinched); /* the event handler */
I'm trying to extend ButtonBarButton to include an additional label that shows the number of updates for the respective box in a viewstack (which is the tabbar's dataProvider).
I can get the additional label (named indicatorLabel) to read an initial value from data, but I can't get it to update automatically like the actual "label" attribute. My understanding was that you could bind to the data object, but that doesn't appear to be the case.
I'm working on a flash game written in pure actionscript 3.0 in Flex. I've just finished implementing replays for the game, but want to store the top 10 hiscores' replay data on my google-app-engine'd website. I'm using Java for the app-engine stuff in Eclipse in java but I have no idea how to deal with communicating to my java code from my actionscript code. I'll need to both read and write from actionscript -> java -> datastore. Does anyone have any experience with this?
For note, I'm horribly noob with anything to do with web development. I hear you can pass arguments to a URL when calling it, comparable to command-line arguments on a desktop executable and if so then sending all the data as a large string would be doable... The question then would be how to call a url from AS3 code with additional data and then how to catch that on the java side.
I believe this is trivia question but here it is.I have created class which loads some image and takes fragments of each for certain animation.And in flash stage where I instance classes, I need to know when loading is complete. How do I proceed that info, I presume dispachevent do that, but how?
How do i create a trace that can detect if an event dispatcher is dispatching an event?....my problem is i've created a custom event that is not being dispatched i use this custom event in other applications and have verified that the code is correct I'm not getting any errors neither it just dies silently
I'm new to Flex.My question is how to dispatch event between components?As far as I know,Flex only bubbles event to itself or its parent. I'm in such a situation:

I want comp1 to dispatch an Event with parameters,according to the parameters some changes could be made to A and B in comp2.How could I get the event in comp2?I know Cairngorm could make a difference,but I don't want to use it right now.Could anyone give me a hand?
I have a class which makes a url request and stores data from that request. When the data is retrieved, parsed, and stored into an array, I'm sending a dispatch event which I listen for in my document class. In the event handler function in the document class, I'm accessing the array that was compiled from the class. The array inside the class has 15 values, however in my event handler function, I'm only retrieving one value from it, which is the last value in the array. I posted my code below. Is there a different way I'm supposed to use the dispatchEvent in order to retrieve all of the array values instead of one?
Class package com.src { import flash.display.Sprite;
I have small chess application which consists of cells and boards. When user moves an item to the board, I want the board cell to dispatch an event so Board can listen to it and call a listener[code]...
I'm trying to do an eventDispatch but the event isn't getting picked up.The dispatch is coming from swf B, and the listener is in swfNot sure if it's an issue because they are 2 files. Does anyone know of a solution?
Basically all I want to know is if there will be a hit on performance as I dispatch events more frequently, or if this is a trivial task for flash to complete.
I have a form with a search field. When user press enter key, I use httpservice to send a query to mySQL database. In some case (a lot) there are several record, so a new window is opening to show those record with a datagrid to let user chose the good result.
My problem is how to send selected information to the first window (with text field). I gess that dispatch event is the way but I don't found how to use
dispatch an event on every 'onProgressEvent' of an external display object loading.
Does dispatching an event frequently cause performance issues?
All I want to do is have a parent class listen for whenever a progressEvent has fired in my loader class, rather than setting up an onEnterFrame loop in the parent class to call 'get' methods within the loader - this seems inefficient to me seeing as onProgressEvents don't occur on every frame.
I dispatched a Custom Event from topic1.swf but its not reflect to main.swf how to do that...?.. is it not possible here... and how to access a public variable/method of topic1.swf from main.swf..
I have two buttons each in its own sprite now I want to listen for mouse overmout and click event on both. In a way that if you roll over button1 its color changes but at the same time button2 color changes as well.
To be more specific lets suppose I have a graphic button like map picutre for a country like UK and then I have text button for UK as well. What I want now is that when user either scrolls over UK map the map button color changes but at the same time the color for UL text button changes as well. same goes for click and out events for the two.
I have a class that loads a swf [AS] private function setupSwf(swfXML:XMLList):void { swfLoader = new Loader (); swfLoader.contentLoaderInfo.addEventListener (Event.INIT, swfLoaded); swfLoader.load (new URLRequest (swfXML.toString())); container.addChild(swfLoader); [Code] ..... I want the swfFinishedHandler() in the main Class to be called when the timeline gets to the dispatchEvent, but its not firing.
I don't know if i've been in front of my computer for too long, but I can't for the life of me understand why this doesn't work:
All i'm trying to do is dispatch an event from one class to the other, when I trace it out, it says the event is getting added, but the event listener isn't picking anything up.
I have a class that extends the MovieClip class, is there a way that I can prevent this MovieClip from dispatching a certain event? More specifically I want to prevent it from dispatching MouseEvent.CLICK under certain conditions.
So I have this class "G" that I use for global vars, and that kind stuff.
Now I want to dispatch an event from that class and no matter what I do the compiler throws the same error: "Call to a possibly undefined method dispatchEvent."
I have already tried extending the EventDispatcher class...
