Actionscript 3 :: Handle A Custom Event In It?
Oct 28, 2010I've created an Event Handler/Listener like so[code]...
Access of possibly undefined property data through a reference with static type flash.events:Event.
I've created an Event Handler/Listener like so[code]...
Access of possibly undefined property data through a reference with static type flash.events:Event.
I defined a simple event class:

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 RepliesA few days ago I decided I wanted to make my own drag&drop flash components, with inspectable properties. Since the documentation for flash components is so limited, I followed the workflow of some blogs I found around the web (mostly about CS3 components). In the end I managed to create a component that has a Live View, that gets a visual update whenever you change the properties (width, height, color..) ....in CS4 !
The problem in CS5 is that when I drag my component on the stage, the timeline of this movieclip starts playing in a loop. As you may or may not know, Components have 1 "Avatar" frame, and 1 "Assets" frame. So this looks kinda weird when that timeline plays.
There is always the possibility that I made a mistake, but when I download the source files from the blog post on the page http://active.tutsplus.com/tutorials/actionscript/creating-flash-compo nents-for-distribution/comment-page-1/#comment-33865
the same thing happens.
When I then save my CS5 FLA as a CS4 FLA and try to use the downloaded component and my own, both of them work fine in CS4. So I think this might be a bug in CS5.? Which is pretty bad because I wanted to use these components in iphone development using the CS5 packager...I read somewhere that we actually use the UIComponent because it has no timeline, so I don't see how it's possible that it plays.

I'm running a recursive function which in the worst case senario is of factorial order. (i.e: runs itself n! times)As soon as n exceeds 7 in these worst case senario's the function times out (Error #1502). I want to handle this error event so that the user can be presented with an error that the problem is too complex.I don't want to extend the timeout period as 15 seconds is reasonable.
View 6 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've a flash site 100x100% in browser window. When I open new tab in browser window Event.RESIZE doesn'tdispatched.how to handle this event except EnterFrame or
Timer listeners?
Do any body know that flash as3 can handle right click event ?
View 2 RepliesI am working on integrating the social network "vkontakte" into my desktop application using Adobe AIR. The flow of authorization in the app is as follows:
Open the web browser with a url, and when the user inputs login and password, redirect to somePage.html. From that URL, I need to get an access_token to sign all future API requests.
So the question really is: How can I listen to an event, which will indicate that the user has logged in successfully, or failed to get that access_token?
Here is the code I am using:
package
{
import air.net.URLMonitor;
import flash.display.Sprite;

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.
Does addEventListener(ErrorEvent.ERROR, handler) handle all type of error event, for example, IOErrorEvent.IO_ERROR, SecurityErrorEvent.SECURITY_ERROR, and other all error events? I'm looking for addEventListener() version of try catch(e:Error)(e:Error can catch all type of errors).
View 2 RepliesI am trying to perform two way binding e.g I have a button (out of many controls), on its selection, I am showing the values of its diff properties(like height, width etc) in some textinput. This one way process works fine.But the reverse process doesn't work. i.e When I select some button, and try to change its dimension by entering some value in height, width textinputs, the dimension are not changed.

You got an eventlistener for an object that can dispatches events in intervals of 0.2ms.And if the eventhandler would need 0.5ms for his operation, what would happen? (listener and handler are in the same class).Would the last event overwrite the event before? In my case, I get some data from a xmlSocket, and I thought, that some datastrings can come in quicker than to work it off in my handler.
View 4 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

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.

I'm not sure if it's possible, but can you override a variable of a parent class like you can override a function? I'm trying to create my own event class that can handle the target property. I have a custom imageLoader class, but when it dispatches it's loading complete event:
ActionScript Code: dispatch(new Event("load_complete")); and a listener picks it up, e.target = null where I would like e.target to equal the imageLoader instance that has finished loading.
Does anyone have an answer or a better way to accomplish what I am aiming for?
I have a couple of Sprites on my screen and I want to write a single event handler to handle the double click on any of those Sprites. The following approach works for every event type except DOUBLE_CLICK:
[Code]...
To make it work, because in my application I will have lots of Sprites. In my opinion, a single event and the target property are more efficient than hundreds of event listeners. Am I right or should add event listeners to every Sprite?
I have an mxml file called HomeView.mxml in a mobile app built using Flash Builder 4.6. In that HomeView.mxml I have an HSlider, which is dispatching events when the thumb is moved. What I'm trying to do is to listen for that valueCommit event in an .as file elsewhere in the project.
Whenever the thumb moves, an event is dispatched in HomeView.mxml:
hSlider.dispatchEvent(new FlexEvent("valueCommit", true));
I can handle that event in HomeView.mxm, but not in an .as class called view.as
In view.as I import the FlexEvent and I then have, in addedToStageHandler:
stage.addEventListener(FlexEvent.VALUE_COMMIT, commitHandler);
Then there's a simple Handler:
private function commitHandler(e:FlexEvent):void
{
trace("committed!");
}
But this code never runs. I do have a handler in the HomeView.mxml file which handles the event, but for other reasons I need to handle it in view.as as well.

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 creating a scrollbar gallery from a tutorial on this site. Though I've completed the tutorial, and customised the gallery to my own needs, however I'm trying to make a very small change to it - and no matter what I do, keep running into problems. I'm trying to replace the rectangular handle with my own customised handle - a (20 x 20) 'circular' png image that I've imported into Flash, made a graphic and stored in the library (though I understand it can be imported using actionscript, like the other images in the gallery).

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?
