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]...
Is there a point of creating custom event class if i dont need to pass custom property with that event?
View 3 RepliesI 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 7 RepliesI've been playing around with custom classes. My objective was to create a custom class (Testing) that would create a box when an instance of the class is created. I've tried three different approaches, however only (3) seems to be showing up. I'm just curious why (1) or (2) doesn't work?
Also is there a better approach than (3)? Since at the moment it's been created on _root. I hope the box can only be accessible through the instance. Since I'd like to incorporate the whole idea of public, private, encapsulation, etc.

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.
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'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)
how to add an event listener to an event from a custom class. Here are the relevent lines of code (I think) from the 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?
I want to dispatch a custom event from the Country() sto the MenuButton();[code]When a country is hovered a custom event is dispatched which I want the MenuButton to listen and if the parameter passed is the same as its name to get highlighted. The Country Class is the Base Class for my countries movieclips I have on stage and the MenuButton the Base Class for the menu button.
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.
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 RepliesThis 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;

I'm still struggling with the complete concept of custom event handling within AS3. I know I am close to a complete understanding it's just not falling into place yet.[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:

Ive been having a problem with a MovieClip prototype. The code i used is below - the problem being that the onLoad event never happens.If i change the onLoad event to apply to the MovieClip class and not the PlaylistItem class then the event fires fine.[code]
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?

Im 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.

I have a problem that seems easy enough to solve but I'm trying to do it with reusable code, which involves doing something I don't understand yet. I've googled this endlessly and read dozens of articles and I'm still just as lost as when I started. I'm hoping a live human being can help me make sense of it.
I have a movie clip on stage. When this movie clip is pressed, I want it to play a certain frame of another movie clip for as long as it's being touched. (It's a map of the US, that will display each state name as it is pressed.) I COULD write 50 different functions, each to call a different frame of the displayName movie, or I could write my own custom event that would be able to receive from each touch event a string variable to then tell displayName which frame to play. So basically, I have, for example:

I have written a Class for skinning the UI. The Class works by taking a movie clip name from the stage passed to it and create the skin for it.So I create an Object from the class such as this:
Code:
var CBox:UI = new UI();
Now what I wanted to do is reference a movie clip from the stage to this CBox variable, so when a call the Class methods it will know which movie clip to work on! Since currently I have to do this:
Code:
CBox.Skinning(content_mc, "content", 100, 200);
or
CBox.Over(content_mc);
As you can see Im passing the movie clip, content_mc, everytime. I just want to avoid this by creating a reference.

View 3 RepliesI want to create a custom class that will create textfields and return them to other classes, but it seems i cant get it working.First i created this custom class named "FormatText" extending Sprite class.Through constructor parameters i pass all the things i need to create a textfield and at the end i put it on the display list using addChild.If i do by this way and i create an istance of FormatText adding it to the display list, my textfield appears, but the problem is that i don't have full control of it, because this new textfield created is still considerated as FormatText's child, so if i try to change some textfield parameters, nothing happens.
Just an example:
