ActionScript 3.0 :: Create Custom Event Class If I Dont Need To Pass Custom Property With That Event?
Dec 28, 2009Is there a point of creating custom event class if i dont need to pass custom property with that event?
View 3 RepliesIs there a point of creating custom event class if i dont need to pass custom property with that event?
View 3 Repliesi am a bit embarassed to ask this, but i do this so much i have to ask. Occasionally, i need to pass/handle custom events on the fly. Rather than creating a whole custom event class, i will just do something like
Code:
myObject.dispatchEvent(new Event('thisCustomEvent'));
//and then handle it later
[code]....
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;
[code]...
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.
How do I create a custom event class similar to ActionScript? What I mean by that is a class that I can use to fire off my own events, send the necessary data.
I don't wanna use third-party libraries like YUI or jQuery to do it. My goal is to be able to send a event that looks like this.[code]...
I am new to AS3, as well as Flash in general, so forgive me if this seems highly elementary. All I am trying to do is create a custom class that extends the MovieClip class and contains a custom property of "marker". I want to be able to use and change the value of this custom property on the timeline for an instance of this class and have it behave just like any other (Ex: this.x ==> this.marker).

I am trying to create a custom resize event as part of a larger project to create a flexible liquid layout class.Basically, i want an object to listen for the stage.RESIZE event. If i can listen for this event from multiple objects, it solves my event firing problem.[code]

View 1 RepliesI hava a custom component and it contains a child icon. If I add a mouse-click event listener to both component(click-listener1) and icon(click-listener2), the event dispatched sequence is click-listener2, then click-listener1. I can understand it. But if I add a custom event to component (listener1), and mouse-click event to icon(listener2), when icon is clicked, the component will dispatch the custom event. In my test, the event dispatched sequence is listener1, then listener2. It doesn't match with event-bubbles rule.
In my opinion The custom event is dispatched in listener2, which triggers listener1. Why event flow sequence is not listener2, listener1?
In component.
icon.addEventListener(MouseEvent.CLICK, iconClickHandler);
private function iconClickHandler(event:MouseEvent):void
{

package components {
public class templateSelection extends VBox {
static public var tempSelectionBag:Dictionary;
[Code]....
I want to have a custom class tempSelection with a Dictionary as a public accessable property of that class. If I use this code, the compiler tells me:
1046: Typ wurde nicht gefunden oder war keine Kompilierungszeit- onstante:Dictionary
Which translates to:
Type was not found or was not a compile-time constant: Dictionary
Is it possible to create a custom event listener other than the ones prebuilt in flash? I sort of know my way around the eventDispatcher class, but can I use it to create my own event to listen for?
View 1 RepliesI'm trying to create a series of scripts that will create some custom event listeners.
I have three movie clips on my stage. One is a movieclip who's sole function is to hold array's and the event listeners. A second which moves around the screen. And a third that is motionless.
The problem is that the argument I want to test (which activates the custom event) is held within a string.
What I want to know is, how do you test to see if the string argument is true?
Is it something similar to this:
var myCode:String="1<0";if(myCode){
trace('one is smaller than 0'); //Strangely apparently one IS smaller than 0!!!
}
I think I'm going about this in the wrong manner, however this is the only way I can think of this working... (since I need to be able to dynamically create these events)
I have a custom Flex 4.5 component (to be used in a List) -
Game.mxml (represents a clickable playing table in a card game):
<?xml version="1.0" encoding="utf-8"?>
<s:ItemRenderer [code].......
But I never see the "game clicked: " trace. Does anybody please know why? I'm probably missing something minor, because I can see the "Clicked: 8946" trace.
This is similar to the question asked here. I am dispatching custom event "ShopEvent" but i am getting error "Type Coercion failed: cannot convert flash.events::Event@81ecb79 to com.events.ShopEvent"Note: Error is thrown from the parent custom component (3rd code snippet), I have added more details thereThis is my custom event. See the first constant, I copy pasted the event name in custom components.
package com.events
{
import flash.events.Event;
[code]......
I have a file TestClass.as:
[Code]...
The dispatchEvent is definitely sending - returns true when I do trace( this.dispatchEvent(new Event( "initComplete", true))); When I run test.fla, fails silently. Function startUp fails to run.
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.

View 9 RepliesI'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:

View 2 Replieshow to create custom event from beginning to end in AS3?I'd like to know how to create a custom event that extends the Event class and then how to dispatch it. Also, I'd like to know how to catch it using the addEventListener() in the format Event.ENTER_FRAME or Event.CHANGE etc...
I'm having some difficulty understanding how events work. I believe "ENTER_FRAME" is a constant holding some value but I don't see how that could dispatch an event. From what I understand; ENTER_FRAME is a static variable of the Event class?

View 6 RepliesIm trying to get my head round what is needed to catch event "Beep2", using dispatchEvent. The function "DoNext" is not firing, even though Im able to produce a trace result of the dispatchEvent "Beep2 true".
This code uses a CustomEvent Class to Extend the Event Class. Its right on my limit of knowledge so far,

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.
View 14 RepliesIm am trying to access my event listners in my "menuButn" class from my doc class.
In my main document class i have the following:
Main.as
public function xmlLoaded(event:Event):void {
var menuButn:Class=getDefinitionByName("com.btn.menuBu tn") as Class;
[Code]......
I have a document class called Main.as In the class constructor I have the following listener:
enter code here
var listeningFORModeChangeToStudent:Sprite = new Sprite;
listeningFORModeChangeToStudent.addEventListener(TellAllModeChangeToStudent.STUDENT,exp);
addChild(listeningFORModeChangeToStudent);
[code]....
In a third class I make a call to the despatcher in the previous class:
enter code here
var ThisTellAllModeChangeToStudent:TellAllModeChangeToStudent = new TellAllModeChangeToStudent;
ThisTellAllModeChangeToStudent.tellAllModeChangeToStudent();
I have trace statements in eveything and from this I know the despatcher in TellAllModeChangeToStudent is being called.The problem is that the listener in the main.as is not calling the function exp.I cant see why and I dont know how to check if the listener is actually seeing the dispatch event?

View 1 RepliesIn a nutshell I have a custom event that I am dispatching from one class that is not getting picked up by the other class even though i have added the appropriate addEventListener calls on its constructor.Here's how the classes are laid out:
application(class/parent)
- network(class/child)
- loginscreen(class/child)
The constructor of the Application class creates and stores references to the network and loginscreen classes:
ActionScript Code:
import com.fg.managers.NetworkManager;
import com.fg.screens.LoginScreen;[code].....
The NetworkManager class extends the MovieClip class as does the LoginScreen and Application classes as well.Now within the oLoginScreen class I dispatch the ValidateCredentialsEvent by calling it this way:
ActionScript Code:
dispatchEvent (new ValidateCredentialsEvent(ValidateCredentialsEvent.VALIDATE_CREDENTIALS, oLoginData, true, false));
Then when I debug the code, I can step through and see that the ValidateCredentialsEvent is being generated but it is never picked up by the oNetworkManager class whatsoever.Is this occuring because the NetworkManager and LoginScreen classes are children of the Application class and because of this can't capture events raised by one another without using the Application class as the intermediary to redispatch these events? My whole idea here was to create a generic network managing object that could be called from anywhere within the application, by any object, using custom events.
