Can someone clear up for me the theory behind the fact you can not redispatch custom event?I am talking about the situation where you get custom event (in your event handler method) and try to dispatch it again as it is - and you get the Error #1034: Type Coercion failed.example:
Code:
package {
import flash.display.Sprite;[code].....
Can someone explain me why when I listen for a custom event and then redispath it it is redispatched as an Event instead of an object of custom event type ?
Exemple : You make un custom event, name it CustomEvent.
In a first class you dispatch an instance of this event and it is managed by a method in a second class, let's say this one :
[Code]...
I missed probably something in event dispatching process but I don't know what. However I found a solution : In the first event manager, dispatch a copy of the custom event received instead of dispatching the object itself. It works in this case.
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]...
Is there a point of creating custom event class if i dont need to pass custom property with that event?
View 3 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

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 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

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"?>

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.

View 2 RepliesI am trying to understand event propagation in Flex framework and have a following doubt on it:
Scenario: I have a built-in component DropDownList on change of which I want to create a custom event refreshPreview and want to propagate it to a custom component PictureComponent.
In the custom component's mxml, I have added the Metadata directive as follows to register a refreshPreview event with the compiler
<fx:Metadata>
[Event(name="refreshPreview", type="flash.events.Event")]
</fx:Metadata>
Layout Details: In my main mxml application I have laid out DropDownList and the custom component such that both are siblings (i.e. have a common indirect parent)
e.g.
<s:Group id="contentGroup">
<s:Group id="formGroup">
<s:Form x="11"
[Code]....
I am seeing that the refreshPreview event is not getting propagated to the custom component.
I doubt this is because the built-in component is a sibling of the target (where the event got generated) and not a parent. how to make refreshPreview event propagate to custom component?

I'm using a Static EventDispatcher for all event handling in my application, and one of the issues with it is that the Static EventDispatcher becomes the target and currentTarget of the custom Event. Usually, I just pass the event to the custom event which it will carry as its own property. I usually call it "scope". So, instead of using "evt.target" or "evt.currentTarget" in the event handler, I use "evt.scope.target" or "evt.scope.currentTarget" instead. This works fine.
The issue is that I want to simplify this with custom events by overriding the target and currentTarget methods so that they return scope.target/scope.currentTarget. At run time, I get an error saying that I cannot convert Event to whatever I named the custom event. So, I tried not extending Event, and that produced an error stating that the class function is expecting exactly 0 parameters. I just want to make it so that people using Static EventDispatcher handling events as they normally would.
So, the question is there a way to override target and currentTarget while extending the Event class, or is there a way to create a custom event without extending Event?
I have four objects with a .speed property. I want to compare all four and snag the object with the lowest speed. That alone I can get a grip on no problem. But, it's quite possible that 2 or more of the objects could have the same lowest speed. Here's where my ideas start to get muddled and rather involved. Compare two, toss the lowest in an array, if equal toss them both in.Compare the third to the array, if it's lower replace the existing item(s) with this one, if it's equal add it.Do a similiar thing with the fourth.To do all that I can't think of anything but a boatload of IFs and nested IFs.
View 3 RepliesI am trying to get a handle on interfaces with AS3 and am kind of at a sticking point. Someone tried to explain them to me using legos¯ and conceptually I get the idea of consistent interaction. Where I seem to get stuck is, I don't really see how the implementation of interfaces¯ accomplishes this.
[Code]....
Lets say we have an online application written in AS3 and served from a server as a SWF. The first version to go out is V1.0.
Several users, some behind a proxy server, use the V1.0 application and now there is a cached copy on the client machines and the proxy server.
V1.1 is released and placed on the server. All users should see V1.1, but results will vary, some will be served the fresh copy, some will for a period receive their cache's copy, and finally some will be served the cache'd copy in the proxy server.
I can be code in the V1.0 that checks a server variable to see if it's out of date. BUT if it is out of date, is there a way in AS3 to force it download a fresh copy, or apply the differences into itself?
Considering that I don't have access to the proxy server and can't manually or automatically clear the cache.
what I am trying to do and maybe some of you nice people can point me in the right direction or present some code examples etc.I am an intermediate Flasher but have never really done anything too hardcore....Here goes.I have an html file(or maybe it's flash depending on what's easier) with 5 radio lists in a form. Each of the lists have post variables that consist of say, option1a,b,c etc... option2a,b,c etc.Once you have checked each option and submit I want to post those variables to an XML file.
NOW STEP 2....I create a flash file with 5 empty movie clips named box1,box2,box3 etc.I create individual LoadMovie actions which dynamically get the name of the .swf file they need to load in each box by calling the variables from the xml file.
I would like to create a swf that pulls images from a folder, creates a thumbnail for them and preloads them. This would have to work like a bare template that could pull 2 or 20 images depending on what folder it is placed in. I'm not asking for code here, what I would like to get from you is thoughts on what works, and what doesn't. paste code if you want to explain someting, but really I just want to be able to wrap my head around this, and then code it myself, and comeback here with specific questions if I run into problems. I would like to keep this to just flash and php if at all possible.
View 5 RepliesI have been using flash since version 3 as a designer.I want to know how to make an object that I have manually placed on the stage from the library with a Class attached to it, interact with the Document Class? So I am basically dragging the item onto the stage and this item has a class attached and the Document Class with all of its SubClasses needs to know this exists.
Now I was dabbling with making geometry wars to learn AS3 Classes and it was great fun, I set up the Document Class, my enemies and Player 1 Spaceship. I worked out my different SubClasses, and everything was added to the stage by AddChild() along with all SubClasses being created through the Document Class....Every Class Object was linked to the Document Class as everything was created either by it or through SubClasses under it. So I had full control to do what I wanted. However, all I ever see are elements generated dynamically to the stage. As a designer I want to animate things here and there and then at specific times possibly gain control of this item with it's Class attached, but I want the Document to have a link to this Item.
Also can everybody please stop generating text boxes dynamically all of the time. just create a MovieClip with the form elements on it if it's a form that isnt going to change in layout at all. But this leads onto the same sort of questions, the items arent being created and added to the stage as objects so you still have to make the MovieClip Class understand the items under it exist, I would do it by the Instance Name but is this dirty these days in AS3..

ActionScript 3, just learning AS3 but know a handful of other languages. What would cause an event that the listen call executes without throwing an error and was successfully dispatched, to not be listened to?
Dispatch call (this runs ):

if ( m_MouseState == MOUSE_STATE_SELECTED )
m_MouseState = MOUSE_STATE_NONE;
else {
m_MouseState = MOUSE_STATE_SELECTED;

The "Squares" are childed to a checkerboard that is childed to my main app ( which extends sprite ). the checkerboard displays and has all the behaviour I want, but when I click a square, the click event fires and dispatches the custom event, but the custom event is never received. That should be all code needed, the rest of the code is just to create a grid and put random numbers in the squares, which works fine. According to every website that has a "custom event tutorial" it would appear that i have everything needed to listen to the event, its just not happening.
