RE: [Flashcoders] Events for custom classes?
You'll need a reference of the dispatching class in your listener class to
receive events:
// broadcasting class
import mx.events.EventDispatcher;
class EventClass
{
// EventDispatcher methods
public var addEventListener:Function;
public var removeEventListener:Function;
private var dispatchEvent:Function;
public function EventClass()
{
}
public function onInit():Void
{
trace('onInit fired!');
dispatchEvent({type: onInit, target: this});
}
}
// listener class
import mx.utils.Delegate;
class ListenerClass
{
public function ListenerClass(eventClass:MyEventClass)
{
eventClass.addEventListener(onInit, Delegate.create(this,
onInitHandler));
}
private function onInitHandler(event:Object):Void
{
trace('onInitHandler invoked');
}
}
// implementation
var eventClass:EventClass = new EventClass();
var listenerClass:ListenerClass = new ListenerClass(eventClass);
eventClass.onInit();

Re: [Flashcoders] Events for custom classes?
Here's a stripped down version (i just left in the methods that dispatch en
event) of my Form base class that uses EventDispatcher.
This class is usually extended by other classes (in an ARP-type framework).
import mx.events.EventDispatcher;
class com.muzakdeezign.core.Form extends MovieClip {
static var symbolName:String = Form;
static var symbolOwner = Object(com.muzakdeezign.core.Form);
var className:String = Form;
// allow class to broadcast events
private static var dispatcherInit =
EventDispatcher.initialize(Object(com.muzakdeezign.core.Form.prototype));
// mix-in from EventDispatcher
var addEventListener:Function;
var removeEventListener:Function;
var dispatchEvent:Function;
var dispatchQueue:Function;
//
// CONSTRUCTOR
//
function Form() {
// trace(Form ::: CONSTRUCTOR);
}
//
// PRIVATE METHODS
//
private function size():Void {
// should be overridden by sub class
this.dispatchEvent({type:size});
}
//
// PUBLIC METHODS
//
public function move(x:Number, y:Number, noEvent:Boolean):Void {
// trace(Form ::: move);
// code removed...
if (noEvent != true) {
dispatchEvent({type:move, oldX:oldX, oldY:oldY});
}
}
public function show():Void {
// trace(Form ::: show)
this._visible = true;
this.dispatchEvent({type:reveal});
}
public function hide():Void {
// trace(FORM ::: hide)
this._visible = false;
this.dispatchEvent({type:hide});
}
}
So assume you then have 2 classes, Application and Login both extending the
Form class and Login is a movieclip inside Application
(Login is a child of Application). The Application could then listen to events
dispatched by the Login.
import com.muzakdeezign.core.Form;
import mx.utils.Delegate;
class Application extends Form {
private var login_frm:Login;
private function onLoad() {
login_frm.addEventListener(show, Delegate.create(this,
this.loginShowHandler));
login_frm.addEventListener(hide, Delegate.create(this,
this.loginHideHandler));
}
private function loginShowHandler(evt:Object):Void {
// login is visible
}
private function loginHideHandler(evt:Object):Void {
// login is hidden
}
}
Note that the Login doesn't listen for events dispatched by the Application
because:
- children don't listen to parents ;-)
If Application had 2 child forms (Login, SomeView), those children wouldn't
communicate with eachother directly, but through the
parent (Application) by dispatching events.
For instance when a user logs in, the Login form could dispatch a loggedIn
event to inform the Application that a login was
successful.
The Application would then respond to that by hiding the Login form and showing
the SomeView form.
import com.muzakdeezign.core.Form;
import mx.utils.Delegate;
class Application extends Form {
private var login_frm:Login;
private var view_frm:SomeView;
private function onLoad() {
view_frm.hide();
login_frm.addEventListener(loggedIn, Delegate.create(this,
this.loginLoggedInHandler));
}
private function loginLoggedInHandler(evt:Object):Void {
// login was successful
// hide login and show other form
login_frm.hide();
view_frm.show();
}
}
Does this help?
regards,
Muzak

For instance when a user logs in, the Login form could
dispatch a loggedIn event to inform the Application that a
login was successful.
The Application would then respond to that by hiding the
Login form and showing the SomeView form.
import com.muzakdeezign.core.Form;
import mx.utils.Delegate;
class Application extends Form {
private var login_frm:Login;
private var view_frm:SomeView;
private function onLoad() {
view_frm.hide();
login_frm.addEventListener(loggedIn,
Delegate.create(this, this.loginLoggedInHandler)); }
private function loginLoggedInHandler(evt:Object):Void {
// login was successful
// hide login and show other form
login_frm.hide();
view_frm.show();
}
}
Does this help?

Muzak

Re: [Flashcoders] Events for custom classes?
Thanks for this sample David,
Just a small correction:
public function ListenerClass(eventClass:MyEventClass)
should be
public function ListenerClass(eventClass:EventClass);
Correct?

Subject: Re: [Flashcoders] Events for custom classes?
Here's a stripped down version (i just left in the methods
that dispatch en event) of my Form base class that uses
EventDispatcher.
This class is usually extended by other classes (in an
ARP-type framework).
import mx.events.EventDispatcher;
class com.muzakdeezign.core.Form extends MovieClip { static
var symbolName:String = Form; static var symbolOwner =
Object(com.muzakdeezign.core.Form);
var className:String = Form;
// allow class to broadcast events
private static var dispatcherInit =
EventDispatcher.initialize(Object(com.muzakdeezign.core.Form.p
rototype));
// mix-in from EventDispatcher
var addEventListener:Function;
var removeEventListener:Function;
var dispatchEvent:Function;
var dispatchQueue:Function;
//
//
//
// CONSTRUCTOR
//
//
//
function Form() {
// trace(Form ::: CONSTRUCTOR);
}
//
//
//
// PRIVATE METHODS
//
//
//
private function size():Void {
// should be overridden by sub class
this.dispatchEvent({type:size});
}
//
//
//
// PUBLIC METHODS
//
//
//
public function move(x:Number, y:Number, noEvent:Boolean):Void {
// trace(Form ::: move);
// code removed...
if (noEvent != true) {
dispatchEvent({type:move, oldX:oldX, oldY:oldY});
}
}
public function show():Void {
// trace(Form ::: show)
this._visible = true;
this.dispatchEvent({type:reveal});
}
public function hide():Void {
// trace(FORM ::: hide)
this._visible = false;
this.dispatchEvent({type:hide});
}
}
So assume you then have 2 classes, Application and Login both
extending the Form class and Login is a movieclip inside
Application (Login is a child of Application). The
Application could then listen to events dispatched by the Login.
import com.muzakdeezign.core.Form;
import mx.utils.Delegate;
class Application extends Form {
private var login_frm:Login;
private function onLoad() {
login_frm.addEventListener(show, Delegate.create(this,
this.loginShowHandler));
login_frm.addEventListener(hide, Delegate.create(this,
this.loginHideHandler)); }
private function loginShowHandler(evt:Object):Void {
// login is visible
}
private function loginHideHandler(evt:Object):Void {
// login is hidden
}
}
Note that the Login doesn't listen for events dispatched by
the Application because:
- children don't listen to parents ;-)
If Application had 2 child forms (Login, SomeView), those
children wouldn't communicate with eachother directly, but
through the parent (Application) by dispatching events.
For instance when a user logs in, the Login form could
dispatch a loggedIn event to inform the Application that a
login was successful.
The Application would then respond to that by hiding the
Login form and showing the SomeView form.
import com.muzakdeezign.core.Form;
import mx.utils.Delegate;
class Application extends Form {
private var login_frm:Login;
private var view_frm:SomeView;
private function onLoad() {
view_frm.hide();
login_frm.addEventListener(loggedIn,
Delegate.create(this, this.loginLoggedInHandler)); }
private function loginLoggedInHandler(evt:Object):Void {
// login was successful
// hide login and show other form
login_frm.hide();
view_frm.show();
}
}
Does this help?

Muzak

Re: [Flashcoders] Events for custom classes?
I'm not sure if you're asking for this level of explanation or not Jason,
but this might help:
I use a BaseClass.as to extend so that I can dispatch events via
GDispatcher:
import com.blitzagency.xray.logger.XrayLog;
import com.gskinner.events.GDispatcher;
/**
* @author John Grden
*/
class com.tomsnyder.util.BaseClass {
// Public Properties:
public var addEventListener:Function;
public var removeEventListener:Function;
public var removeAllEventListeners:Function;
// Private Properties:
private var dispatchEvent:Function;
private var log:XrayLog;
function BaseClass()
{
GDispatcher.initialize(this);
log = new XrayLog();
}
}
So, with this, I just create a new class that extends BaseClass, and bingo,
I have eventDispatching capabilities:
import com.tomsnyder.util.BaseClass;
/**
* @author John Grden
*/
class BaseMain extends BaseClass
{
public static var SOMETHING_COMPLETE:String = somethingComplete;
function BaseMain()
{
super();
}
}
Now, I can just as easily add my listener from another class that has access
to BaseMain:
BaseMain.addEventListener(BaseMain.SOMETHING_COMPLETE, Delegate.create(this,
somethingCompleteHandler));
private function somethingCompleteHandler(e:Object):Void
{
trace(log.debug(somethingCompleteHandler called, e));
}
For scope, just use mx.utils.Delegate or Steve Websters delegate
Does that help or am I missing your question?

RE: [Flashcoders] Events for custom classes?
Helen, Great, thank you. However, I'm a little confused on how I apply that to my code I posted. All the MM docs on Event Dispatcher show using it with Adove classes or components. And how about the scope with my Webservice event? That scope is outside of my custom class, so how do I fire the event in my custom class? I can add a property to the listener object which is the AdminData class instance, but that seems kludgy.

RE: [Flashcoders] Events for custom classes?
Here is your code modified to use the EventDispatcher:
import mx.events.EventDispatcher; // import the event dispatcher
class com.boa.projects.iqrcgenerator.components.AdminData{
public var addEventListener:Function; // Set the functions
public var removeEventListener:Function; // Set the functions
private var dispatchEvent:Function; // Set the functions
private var userData:Object;
// I'm sure you have a different constructor, but you need
// to add that line to it if you want to use the eventdispatcher
public function AdminData(){
mx.events.EventDispatcher.initialize(this); // add this
to constructor
}
public function wsUserDataByLOB(lobDbId:Number):Void{
var getUserListResult:Object = new Object();
getUserListResult =
generatorWebService.GetUserList(lobDbId);
var r = this; // To get this in onResult
getUserListResult.onResult = function(oUser){
r.dispatchEvent({type:eventOnResult,
user:oUser}); // Dispatch the event
}
}
// I may just take this function out all together since the
event can
// autommatically send them the data.
public function getUserData():Object{
return userData;
}
}
Then in your other class you can do something like:
//myAdminData is an instance of the class above
var r = this;
r.eventOnResult= function(evtObj:Object){
trace(user: + evtObj.user); // Should return the oUser
object
}
// addEventListener takes the event name, and who you want to listen
myAdminData.addEventListener(eventOnResult, r);
Does that help? I obviously can't test the code, but I think everything
is right... I have trouble with scope, which is why I use a lot of 'r'
values instead of 'this'... Just easier for me... Probably not a good
coding standard :)

Subject: [Flashcoders] Events for custom classes?
OK, I'm pretty good at Actionscript 2.0, but something I never really
understood and now need to.
Core question: How do I make an event in a custom class, and how do I
make a listener in another class listen for the event?
EventBroadcaster in the help docs seems to only show how to use it with
Adobe classes and components. Docs on listener are the same. I know how
to set up listeners for other events, like keypresses and mouse
rollovers. Easy enough. But my problem is this (see comments in code
below):
class com.boa.projects.iqrcgenerator.components.AdminData{
private var userData:Object;
public function wsUserDataByLOB(lobDbId:Number):Void{
var getUserListResult:Object = new Object();
getUserListResult =
generatorWebService.GetUserList(lobDbId);
getUserListResult.onResult = function(oUser){
//this works fine,
//I can capture this event result here,
//but how do I notify another class?
//also what about scope here?
//how to set userData as oUser result?
//can I fire an event in my AdminData
//class from here?
}
}
public function getUserData():Object{
//can't let user get this data
//until Webserive event is done.
return userData;
}
}

Re: [Flashcoders] Events for custom classes?
If you use dispatchEvent from any class, any other class that's listening for it can respond. No scope issues that I can see. I have a simple example of two classes talking to each other using EventDispatcher at http://flash-creations.com/notes/sample_emailer.php if you want it -- click the free download on the right. Helen Merrill, Jason wrote: Helen, Great, thank you. However, I'm a little confused on how I apply that to my code I posted. All the MM docs on Event Dispatcher show using it with Adove classes or components. And how about the scope with my Webservice event? That scope is outside of my custom class, so how do I fire the event in my custom class? I can add a property to the listener object which is the AdminData class instance, but that seems kludgy.

RE: [Flashcoders] Events for custom classes?
Also if you want to create your own onResult Event (it's not a real event)
you can do this without EventDispatcher or listeners :
class com.boa.projects.iqrcgenerator.components.AdminData{
public var onResult:Function;
private var userData:Object;
public function wsUserDataByLOB(lobDbId:Number):Void{
var getUserListResult:Object = new Object();
getUserListResult =generatorWebService.GetUserList(lobDbId);
getUserListResult.onResult = Delegate.create(this,
resultHandler);
}
private function resultHandler(oUser:object) {
// handle the data however you want ..
// now trigger the onResult method
this.onResult(oUser);
}
//... the rest of your class below
}
Now in another class where you import AdminData with say an instance called
admData :
var admData:AdminData = new AdminData();
admData.onResult = function(oUser) {
// your code handling here
}
As for a method with EventDispatcher, you'll find pretty much what you need
with what the others gave you ! :)

RE: [Flashcoders] Events for custom classes?
Daniel, try as I may, I can't get your code to work. I have one class,
which has a combobox. I can get the event to fire when the combobox
changes just fine, but I can't get it to hear the firing of the data
capture from the webservice in the other class.
So basically, in pseudocode, I need to do this:
class A{
make comboBox
make datagrid
when comboBox changes, use Class B
to get data from webservice
when webservice result received,
update datagrid with new data
}
class B{
connect to webservice
when requested, return data to requesting class
}
Reason I want these two classes to be separate is because I want other
classes to call Class B to get data as well. So, I can do all of those
things just fine, they are all working, except for the last part, when
requested, return data to requesting class - I figure since the
webservice is asynchronous, I need to capture the received event, which
is fine, I can do, that works. But I need to tell Class A to update the
datagrid with the new data when it gets it from Class B - so an event
model is required.
in your code, you have a var r in both the Class A and Class B - I'm
confused about that. Thanks for any help.

Re: [Flashcoders] Events for custom classes?
do you have a reference to the class that is broadcasting the event in the
class that's listening for the event?
meaning, when you write your addEventListener in your Receiving class, you
should have:
referenceToBroadcastingClass.addEventListener(myEvent,myHandler);

RE: [Flashcoders] Events for custom classes?
Jason,
So if I understand clearly what you want to do is :
From Class A : (pseudo code following)
class ClassA {
private var instClassB:ClassB;
make comboBox
make datagrid
function ClassA() {
instClassB = new ClassB();
comboBox.onChange = Delegate.create(this, cbChangeHandler);
instClassB.addEventListener(webServiceResult, this);
}
function cbChangeHandler(e){
instClassB.getWSdata(e.value);
}
function webServiceResult(evtObj:Object) {
update datagrid with evtObj.newData
}
}
class ClassB {
Decorate with EventDispatcher methods
dispatchEvent, addEventListener, removeEventListener
function ClassB() {
EventDispatcher.initialize(this);
}
function getWSdata(val) {
get data from web service
wsInstance.onResult = Delegate.create(this,
wsResulthandler);
}
function wsResulthandler(data) {
this.dispatchEvent({type:webServiceResult, newData:data})
// add anything you want to pass in the object
}
}
Now you have them both communication the way you want
Have fun !

Daniel, try as I may, I can't get your code to work. I have one class,
which has a combobox. I can get the event to fire when the combobox changes
just fine, but I can't get it to hear the firing of the data capture from
the webservice in the other class.
So basically, in pseudocode, I need to do this:
class A{
make comboBox
make datagrid
when comboBox changes, use Class B
to get data from webservice
when webservice result received,
update datagrid with new data
}
class B{
connect to webservice
when requested, return data to requesting class }
Reason I want these two classes to be separate is because I want other
classes to call Class B to get data as well. So, I can do all of those
things just fine, they are all working, except for the last part, when
requested, return data to requesting class - I figure since the webservice
is asynchronous, I need to capture the received event, which is fine, I can
do, that works. But I need to tell Class A to update the datagrid with the
new data when it gets it from Class B - so an event model is required.
in your code, you have a var r in both the Class A and Class B - I'm
confused about that. Thanks for any help.

Here is your code modified to use the EventDispatcher:
import mx.events.EventDispatcher; // import the event dispatcher
class com.boa.projects.iqrcgenerator.components.AdminData{
public var addEventListener:Function; // Set the functions
public var removeEventListener:Function; // Set the functions
private var dispatchEvent:Function; // Set the functions
private var userData:Object;
// I'm sure you have a different constructor, but you need
// to add that line to it if you want to use the eventdispatcher
public function AdminData(){
mx.events.EventDispatcher.initialize(this); // add this to

}
public function wsUserDataByLOB(lobDbId:Number):Void{
var getUserListResult:Object = new Object();
getUserListResult =

var r = this; // To get this in onResult
getUserListResult.onResult = function(oUser){
r.dispatchEvent({type:eventOnResult,
user:oUser}); // Dispatch the event
}
}
// I may just take this function out all together since the event
can
// autommatically send them the data.
public function getUserData():Object{
return userData;
}
}
Then in your other class you can do something like:
//myAdminData is an instance of the class above
var r = this;
r.eventOnResult= function(evtObj:Object){
trace(user: + evtObj.user); // Should return the
oUser object } // addEventListener takes the event name, and
who you want to listen
myAdminData.addEventListener(eventOnResult, r);
Does that help? I obviously can't test the code, but I think
everything is right... I have trouble with scope, which is
why I use a lot of 'r'
values instead of 'this'... Just easier for me... Probably
not a good coding

do you have a reference to the class that is broadcasting the event in the class that's listening for the event? Yes, that's this part of his code: myAdminData.addEventListener(eventOnResult, r); Where he has r = this in his code Jason Merrill Bank of America Learning Organizational Effectiveness ___ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com

Jason,
So if I understand clearly what you want to do is :
From Class A : (pseudo code following)
class ClassA {
private var instClassB:ClassB;
make comboBox
make datagrid
function ClassA() {
instClassB = new ClassB();
comboBox.onChange = Delegate.create(this,
cbChangeHandler);
instClassB.addEventListener(webServiceResult, this);
}
function cbChangeHandler(e){
instClassB.getWSdata(e.value);
}
function webServiceResult(evtObj:Object) {
update datagrid with evtObj.newData

}
class ClassB {
Decorate with EventDispatcher methods
dispatchEvent, addEventListener, removeEventListener
function ClassB() {
EventDispatcher.initialize(this);
}
function getWSdata(val) {
get data from web service

RE: [Flashcoders] Events for custom classes?
I think Matthew has what you are looking for. Alain's solution should
do what you want too.
If you want to write two classes with lower cohesion so they aren't
referencing each other, you could write a third control class which
would have code similar to the following. This way objA and objB don't
need to know about each other. If another class needs to start
listening for results of the webservices, you add it in here, rather
than making changes to your other classes.
Class controller {
Var objA = new ClassA();
Var objB = new ClassB();
this.eventComboBoxChanged = function(){
// execute functions on B
}
this.eventWebserviceResultsRecieved = function(){
// execute fuctions on B
}
this.eventDataRequested = function(){
// execute functions on A
}
objA.addEventListener(eventComboBoxChanged, this);
objA.addEventListener(eventWebserviceResultsRecieved, this);
objB.addEventListener(eventDataRequested, this);
}
Again, I haven't tested this code, but the basic idea should work as
long as objA and objB are dispatching the events when the changes occur.

do you have a reference to the class that is broadcasting the event in
the
class that's listening for the event?
meaning, when you write your addEventListener in your Receiving class,
you
should have:
referenceToBroadcastingClass.addEventListener(myEvent,myHandler);

Hi Jason,
I have my own implementation of AsBroadcaster/EventDispatcher (bundling both
in one class), which is very flexible and can be used with inheritance or
composition (But unlike the standard implementations, it's not a mix-in
class). If you'd like me to send you the class, just let me know.

I've read a lot about them, but it's hard to know how to apply to specific projects sometimes, so I do a lot of tight-coupled composition type coding sometimes - not the best approach though. Trying to separate model and view here, but the event stuff is stuff I just really need a handle on. Thanks for the samples! There was a Matthew that posted something?

Alain,
Been following your suggested method, it's great, and everything works as
advertized, except can't get wsResulthandler to fire once the Webservice data
is received.
Also, how do I send the data from the comboBox change event through to the
getWsData function? I need to know the data from the selected item in the
combobox, as that is a parameter I sent to the webservice to get the data. I
hard coded it a number for now, but it doesn't work because of the first
problem.
Here is a snippet of the code in Class B
function getWSdata(lobDbId:Number) {
var getUserListResult:Object = new Object();
getUserListResult = root_mc.generatorWS.GetUserList(1)
//lobDbId);
getUserListResult.onResult = Delegate.create(this,
wsResulthandler);
}
function wsResulthandler(data) {
_level0.traceMsg(WS Result recieved.)
this.dispatchEvent({type:webServiceResult, newData:data})
}
Did I set that up right?
Thanks,

Jason,
So if I understand clearly what you want to do is :
From Class A : (pseudo code following)
class ClassA {
private var instClassB:ClassB;
make comboBox
make datagrid
function ClassA() {
instClassB = new ClassB();
comboBox.onChange = Delegate.create(this,
cbChangeHandler);
instClassB.addEventListener(webServiceResult, this);
}
function cbChangeHandler(e){
instClassB.getWSdata(e.value);
}
function webServiceResult(evtObj:Object) {
update datagrid with evtObj.newData
}
}
class ClassB {
Decorate with EventDispatcher methods
dispatchEvent, addEventListener, removeEventListener
function ClassB() {
EventDispatcher.initialize(this);
}
function getWSdata(val) {
get data from web service
wsInstance.onResult = Delegate.create(this,
wsResulthandler);
}
function wsResulthandler(data) {
this.dispatchEvent({type:webServiceResult,
newData:data}) // add anything you want to pass in the object
}
}
Now you have them both communication the way you want
Have fun !

Subject: RE: [Flashcoders] Events for custom classes?
Daniel, try as I may, I can't get your code to work. I have
one class, which has a combobox. I can get the event to fire
when the combobox changes just fine, but I can't get it to
hear the firing of the data capture from the webservice in
the other class.
So basically, in pseudocode, I need to do this:
class A{
make comboBox
make datagrid
when comboBox changes, use Class B
to get data from webservice
when webservice result received,
update datagrid with new data
}
class B{
connect to webservice
when requested, return data to requesting class }
Reason I want these two classes to be separate is because I
want other classes to call Class B to get data as well. So,
I can do all of those things just fine, they are all working,
except for the last part, when requested, return data to
requesting class - I figure since the webservice is
asynchronous, I need to capture the received event, which is
fine, I can do, that works. But I need to tell Class A to
update the datagrid with the new data when it gets it from
Class B - so an event model is required.
in your code, you have a var r in both the Class A and
Class B - I'm confused about that. Thanks for any help.

Here is your code modified to use the EventDispatcher:
import mx.events.EventDispatcher; // import the event dispatcher
class com.boa.projects.iqrcgenerator.components.AdminData{
public var addEventListener:Function; // Set the functions
public var removeEventListener:Function; // Set the functions

private var userData:Object;
// I'm sure you have a different constructor, but you need
// to add that line to it if you want to use the eventdispatcher
public function AdminData
RE: [Flashcoders] Events for custom classes?
Nevermind the second part of the question about passing the combobox data, I
figured that out:
(in class A)
function cbChangeHandler(e){
var t_cb:ComboBox = e.target;
var thisData:Number =
t_cb.dataProvider[t_cb.selectedIndex].data;
adminData.getWSdata(thisData);
}
But the first part of my question regarding getting wsResulthandler to fire
once the Webservice data is received is still an issue. Any ideas?

RE: [Flashcoders] Events for custom classes?
Jason,
By the look of it, you will never receive an onResult for your
getUserListResult ... it's a simple Object and no Method onResult exists for
that class that I know of ...
What are you using to make your webservice calls ? are you using Flash
Remoting ?
if so you should use the responder to handle the result.
import mx.remoting.Service;
import mx.remoting.PendingCall;
import mx.rpc.RelayResponder;
import mx.rpc.FaultEvent;
import mx.rpc.ResultEvent;
var myService:Service = new Service( gatewayUrl , null , serviceName , null,
null );
var pc:Pendingcall = new PendingCall();
pc.relayResponder(myService, handleResult, handleError);
well I can't really remember from the top of my head, I'll need to look it
up from home,
but this is somewhat how you can know when the data has arrived from the
webservice.
So your class be ends up beeing a Service caller, you can make it a
Singleton and use it to fetch different services from your gateway.
You should definitely look into the ARP framework (or other similar
projects) ... that's how I learned how to best use Design Paterns :) after 2
projets with it, you'll definitely understand :)

Hi Jason,
I have my own implementation of AsBroadcaster/EventDispatcher
(bundling both in one class), which is very flexible and
can be used
with inheritance or composition (But unlike the standard
implementations, it's not a mix-in class). If you'd like me to send

function wsResulthandler(data) {
this.dispatchEvent({type:webServiceResult,
newData:data}) // add anything you want to pass in the object
}
}
Now you have them both communication the way you want
Have fun !

Subject: RE: [Flashcoders] Events for custom classes?
Daniel, try as I may, I can't get your code to work. I
have one
class, which has a combobox. I can get the event to fire
when the
combobox changes just fine, but I can't get it to hear
the firing of
the data capture from the webservice in the other class.
So basically, in pseudocode, I need to do this:
class A{
make comboBox
make datagrid
when comboBox changes, use Class B
to get data from webservice
when webservice result received,
update datagrid with new data
}
class B{
connect to webservice
when requested, return data to requesting class }
Reason I want these two classes to be separate is because I
want other
classes to call Class B to get data as well. So, I can
do all of
those things just fine, they are all working, except
for the last
part, when requested, return data to requesting class -
I figure
since the webservice is asynchronous, I need to capture the
received
event, which is fine, I can do, that works. But I need to
tell Class
A to update the datagrid with the new data when it gets it
from Class
B - so an event model is required.
in your code, you have a var r in both the Class A and
Class B
