Flex :: Usage Of Custom Event With Properties... Multiple Events And Single Listener?
Jan 6, 2010
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.

I want to have a single event listener for multiple events and depending on the type of event i want to handle them separately.Something similar to Swiz framework see: 'Handling Multiple Events from a Single Method'.i have a piece of code like
var toolOptions:UIComponent=ToolOptions.createToolOptions(type);
if (options != null)
{[code]....
In above toolOptions is a mxml component which get dynamically created based on 'type'.Also which type of event should be dispatch the event from the component? eg: Event.SELECT. To be more precise the above is basically required for a toolbar.When user selects a tool,he is shown options for a tool and when he selects options,tool should apply them to object on the view.

Can I create a single event listener for all mouse events ?
my understanding is no because: what's happening is that each listener is checking for a string in an event and comparing it for a match against a list which is the listener.

I want each item in a list to change to a totally unique view file. Instead of 10 items in a list all going to 1 new view but with different info being generated I want 10 different view, 1 per item in the list. I can't find any examples of how to do this and I have been tryingo to make it for for a while. This is for a mobile app.

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()

I notice in actionscript 3 that when a handler gets called, its able to access the senders properties. If I dispatch an event from my custom class. can all the listeners inherit all my public properties and methods?

This is NOT duplicate of my earlier post (its is slightly different)But this is similar issue with similar error but its not the same error The error I am getting now is below while dispatching the custom event from my custom component
TypeError: Error #1034: Type Coercion failed: cannot convert events::MapEvent@a74ab51 to flash.events.MouseEvent.
dispatchEvent(new MapEvent(MapEvent.CLICKED_ON_MAP));
Note: The error in my earlier post is giving below error message
Type Coercion failed: cannot convert flash.events::Event@81ecb79 to com.events.ShopEvent
The difference here are two things, the earlier error is while converting flash event to custom event and now this one is while converting custom event to flash event and secondly, I have no clue why it is trying to convert to the mouseevent where I am just dispatching my custom event with proper listeners.
This is my custome event
package events
{
import flash.events.Event;
import ui.map.MapElement;

Is there a way, in ActionScript 2, to set multiple properties for an exising movieclip in one command?
For example, is there a way to write something like this more succinctly?:
myMovieClip._x = 10;
myMovieClip._y = 10;
myMovieClip._alpha = 100;

In short: I need an event listener in a custom component so all its instances (without editing them) react at the same time, fired by a dispatched event in its parent container. In detail: I have a custom component with Tab navigator. (The tabs are intended to show different preferences for different Languages.) I have a button bar with buttons for all the languages. There are a lot of instances of the custom component.
I want to click in a button of the languages bar and get ALL the instances switched to the same tab (the custom component contains the logic to change the tab). I can do it by adding the event listener for EACH INSTANCE of the custom component, so it calls an internal function that changes the tab. But it seems to be very coupled, isn't it? I wonder if it can be done in the master CLASS of the component, so it listen for events in its parent container, whichever it is. In my mind this code shoud work, but it doesn't (obviously ill'use a custom event to pass the new language value): this.parent.addEventListener("lang_change", this.change_tab); This way I can just drop an instance of the component, and see it working for itself.

This isn't an exact duplicate of AS3: add event listener to loaded swf, actually it seems to be a mirror situation with non-mirror solution..
I have a test flash file that registers its own listener at first frame's actions.
trace("it's going to be OK");
stage.addEventListener(KeyboardEvent.KEY_DOWN, aKey);
Unfortunately neither line works when .swf is loaded into another movie. Assuming that stage object is wrong for such situations, which object should be used to get listener?
Is it necessary to rewrite loader in parent swf, as said in the linked question?

This might be more of a subjective question, but is it generally best practice to have one dedicated method per event-types that you add an event-listener?
Such as:
myButton.addEventListener(MouseEvent.MOUSE_OVER, onMouseOver);
myButton.addEventListener(MouseEvent.MOUSE_OUT, onMouseOut);
//Somewhere else in the code...
[Code].....
And if you had a MouseEvent.MOUSE_UP, MouseEvent.MOUSE_DOWN and other relevant MouseEvents event-listeners to watch for, you could even set a switch statement to handle all the various MouseEvent types.

I have a button (toggleBtn) when clicked dispatches the following custom event - dispatchEvent(new Event("togglePause"));
I have second object with a listener listening for this dispatch. Not sure what to attach this listener to to receive the dispatch. Attaching the listener to the stage does not work for me. It might be worth mentioning both the these objects are external objects instantiated in the document class.

For graphical representation I use fla file as a resource. I work in Flash Builder 4.6 to code. I try to create own class Panel which contains the click event. But event doesn't work when I test the move! When I move the event handler (buttonClick) and event listener to main class (test) and apply the event to the card object (for example), all works fine.

I'm trying to add an eventListener to a custom class. I created a motion tween in CS4 and exported the motion as as3, which then gave me a chunk of code.I then took that code and turned it into a class. What I'd like to be able to do is set up an event listener in my FLA to listen for when this animation is done playing, however, I have been unable to get that to work. Do I need to add something else to my class? Is there something wrong with how I'm trying to implement the class in my FLA?Here's the code for the class:

I have an issue catching a custom event that I am firing. I have a view, let's call it "A" which calls a webservice "B", and when that webservice returns with data it fires a custom event "C". "A" is listening for that custom event but never hears it being broadcast. I have trace() lines in each method of the classes and they all fire in turn except the listener.

The event is not Firing!!!!!!!!!! Why? The "hitplayer" is supposes to fire and thats the one I'm having the problem with. It wont even trace. I know its a problem with the event because it works fine with Event.ENTER_FRAME.the listener:

public function FightingGame() {
adEventListener(Event.ADDED_TO_STAGE, FightingGameBuild, false, 0, true);

my event listeners does not catch a custom event while all of the others do. I have this in my FLA:
[Code].....
...which obviously means p5.finished() executed AND NGDemoEvent successfully fired the custom event. But I don't get the trace from closeP5Handler() (and obviously not from closeP5).
My FLA file has six other such function calls to six other classes (P2, P3, etc.) and these all work. They're identical. I'm tearing my hair out over this. Why won't the listener get the event?

I'm having a problem with a custom subclassed Event class. Or I should say, I'm having trouble receiving events from this custom event class. I'm pretty sure I have everything wired correctly, the event is dispatched properly and my trace shows the Event instance being spawned. However, my eventListener, which is in another class, never fires its handler function.Have any of you run across instances where custom event classes fail to fire? I'm about at my wit's end.

Here's a hodge-podge of information:
Custom Event Class:
Code:
package com.events {[code]...
I made a custom loader to replace the urlLoader and even tried a replacement for the _loader using the same custom event.Works great for the first addEventListener:
Code:
urlLoader.addEventListener(Event.COMPLETE, onSwfLoaded).But stops on the second addEventListener.If I just apply the custom event to the following...
Code:
_loader.addEventListener(Event.COMPLETE, onLoaderInit);
VERSUS
Code:
_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoaderInit);it works just fine.As soon as I use it on the contentLoaderInfo line, it throws that type error cannot convert CustomEvent to Event error.I also double checked that my custom event listener was overriding clone()properly and it looks like it does.

I'm trying to figure out if it's possible to run multiple buttons using a single addEventListener so that I don't have to create extra code. For example, in the code below I have my instance name "btnCA" which is on my movie clip. It works great and there are no issues with this code, but I need to add more buttons. Does that mean I have to copy and paste this code for each button or is there a way to add multiple instances to an event listener?
Sample code:
buttonMode = true;useHandCursor = true;

I have been focusing on PHP a lot lately and just had a client that requires an MP3 player playing multiple songs so I had to whip out my rusty actionscript skills. I have the player completed and it is working as desired. The down side is it has multiple songs. I am using separate functions for each song and separate event listeners. My main question is there a way to combine these funtions into one and just use the event listener to pass another variable to the functions? Below is a sample of one of the code for Song1. I would like to make it so anywhere there is Song1 in the code, I can make it a variable so I can put in for example (Song2, Song3, Song4, etc.) This way, I can have one or two functions handle all the songs instead of having to copy, paste and then find and replace.
// Song 1
var Song1:Sound = new Sound();
pbSong1.source = Song1;
//pbSong1.visible = false;
var Song1Loaded:Boolean = false;
