Flex :: 3 - Dispatch Event Between Components?
Sep 4, 2009
I'm new to Flex.My question is how to dispatch event between components?As far as I know,Flex only bubbles event to itself or its parent. I'm in such a situation:
[Code]...
I want comp1 to dispatch an Event with parameters,according to the parameters some changes could be made to A and B in comp2.How could I get the event in comp2?I know Cairngorm could make a difference,but I don't want to use it right now.Could anyone give me a hand?

I am having trouble using a custom event in flex. I need to dispatch an event from inside two nested components and receive it in the main application file. The basic set up is a main application file importing a custom "gallery" component.

I have a checkbox that is bound to a property:
<mx:CheckBox label="Show All" selected="{showAll}"/>
I want to trigger an event when the checkbox is toggled that will read the value of showAll after a change:
<mx:CheckBox label="Show All" selected="{showAll}" click="_list.refresh()" />
Where, in this case, _list is an ArrayCollection object whose filter function depends on the showAll field to choose values.It turns out that this doesn't work, or at least gives a strong appearance of not working (what with the values in the list not changing and all). Is there a documented order of events for this, so that I can discover which events are dispatched in which order, and whether the binding value change will have fired the time the click event is dispatched? Alternately, can someone recommend a better way of doing this?

Is there a way how modules can listen to parent application event? My current solution that works is:
private function directoryRemoteObject_saveCompany_resultHandler(e:ResultEvent):void
{
this.directoryModuleLoader.child.dispatchEvent(new CompanyEvent(CompanyEvent.COMPANY_SAVED, e.result as int));
}
this means that I need to dispatch event for every module.

So I'm trying to build a tool that will allow me and other users to all open the same .swf, and then I as the Admin user am able to interact with mine while they all see my mouse movements and button clicks etc on theirs.I'm using BlazeDS to manage this and I'm getting data sent back and forth etc - no difficulties there. The issue I'm running into is this:
In an "Admin" instance, I click a button. I capture that X and Y, then tell Blaze to tell my clients to dispatch a Click event at that X and Y. On my client side, I get that data and dispatch a Click event at that X and Y - but the click is actually caught at the stage level. The click on my client side takes place UNDER all of my buttons and other content - so the whole thing fails.Is there a way to tell it to start the click event at the top?

What I want to do is to dispatch the click event when the component is clicked. (The class is essentially some text in a textfield that needs to be able to do certain things, and it needs to be able to respond to a click). Sounds easy enough... I want the event dispatched when that portion of the text is clicked. But uh...how? it's not like a button where I can just go myButton.addEventListener(MouseEvent.CLICK, myClickHandler);That's clear, because some component is going to be listening for the Click event dispatched when myButton is clicked. It is built into the AS3 framework that a button knows how to listen for a click event.
After the import statements I've got:[Event(name="click" type="mx.events.Event")]How do I dispatch the event when the component is clicked, when the component doesn't yet know how to respond to a click event? I've tried adding an event listener in the textfield which contains this custom class of text, but nothing's happening because the Click event hasn't been dispatched.

I've a Flex application which loads a Flash swf via SWF loader; the Flash swf is in AS3. the flash swf has code to dispatchEvent a Text Event
Flash Code:
var re:TextEvent = new TextEvent(TextEvent.TEXT_INPUT,true,true);
Flex Code:
<mx:SWFLoader source="menu.swf" id="mnu" complete="menuLoaded(event)" />
private var mySwfMve:MovieClip;
function menuLoaded(event:Event): void {
[Code]....
I don't see any TextEvents being dispatched from Flash. They are not seen in the debug trace.. I can capture enter frame events however.

I have a standard combobox that dispatches a collection event when the dataprovider finishes initializing:
my_cb.addEventListener( CollectionEvent.COLLECTION_CHANGE, getMyStuff );
Then I have a custom component that also has a dataProvider. How do I get it to dispatch a collection change event when its dataprovider finishes loading?From what I've read, I can't do it. Will dispatching a propertychangeevent work?
UPDATE:I have a custom component that I call 'SortingComboBox' but it is not a ComboBox at all; it extends Button and I set is dataProvider property to my arraycollection, model.product (which is an arraycollection). how I use the dataProvider in that component:
code
[Bindable]
private var _dataProvider : Object;
public function get dataProvider() : Object
{[code]..........
In the createChildren() method of this component, I use this:
BindingUtils.bindProperty(dropDown, "dataProvider", this, "dataProvider");
The dropDown is a custom VBox that I use to display labels.

I'm fairly experienced with Flex 4, but I still haven't needed frameworks yet (I like to do everything myself) and don't want to use them either, I know it's advantages and have learned how to use one of them, but still, no.
How can I dispatch an event in the main application and have a component inside a popupmanager to react to that event? All this dispatching the event within the main app and NOT aiming it to the popupmanager or the component instance, I want to be able to fire the event and not care about who gets it or if anyone reacts to it at all so if that is possible then I wouldn't care about keeping track of said popups.
I already dispatch an event from the component and receive it in the main application by bubbling the event and therefore being agnostic of each other, now I want it backwards.

Is there an event dispatched when a modal is brought to the front in Flex? Basically there are two times when I would want to listen for this event: When the modal is first created (although in theory creationComplete / show / etc.. could suffice here). When the user brings a modal that is not in the front to the front by clicking on it. In my case the popups I am working with are descendants of TitleWindow and listening for focusIn does not seem to work reliably.

I got a question about event dispatching and dispatching in flex.
My goal is to pass an email address captured in one component (Comp1) and be passed to another (Comp2). These two components are navigator content of a viewstack. The custom event dispatched the email correctly from Comp1 but somehow could not reach Comp2. The application (Main) looks like :

I am trying to get some code working from an example I came across. most of the functionality works but it is failing when it tries to dispatch a custom event. At the moment the code that is trying to dispatch the event is inside a class that handles amf remoting.the example has this line in it for the dispatch:
Application.application.dispatchEvent(new
RemoteResultEvent(RemoteResultEvent.USER_UPDATE_COMPLETE,"test"));
but that fails as it does not know what application.application is "Multiple markers at this line:
-Access of undefined property application"
I assume that this is because this was not written for a mobile app. I tried changing the dispatcher to EventDispatcher
EventDispatcher(
new RemoteResultEvent(RemoteResultEvent.USER_UPDATE_COMPLETE, "worked"));
but I then get this error:
TypeError: Error #1034: Type Coercion failed: cannot convert events::RemoteResultEvent@18337731 to flash.events.EventDispatcher.
This is the code in the custom event RemoteResultEvent.as :
package events
{
import flash.events.Event;
public class RemoteResultEvent extends Event {

I am trying to dispatch a custom event from one flex module to another.The code which dispatch the event is as below Application.application.Destination.child.dispatchEvent(
new AlgoEvent(AlgoEvent.GETFROMPARENT_LOCAL_EVENT));
here AlgoEvent is a custom event.on the other side the module which catches and handles the event has this code:
public function sendParametersToChild(e:AlgoEvent):void
{[ code]...
but when the statement Application.application.Destination.child.dispatchEvent(new AlgoEvent(AlgoEvent.GETFROMPARENT_LOCAL_EVENT)); is executed the debugger give the following run time exception:
TypeError: Error #1034: Type Coercion failed: cannot convert resources.events:: AlgoEvent@4182239 to resources.events.AlgoEvent.at flash.events::EventDispatcher/dispatchEventFunction()[code]...........

I stumbled upon and interesting problem concerning spark's VideoDisplay-Component. It seems that it doesn't dispatch DoubleClick-Events. For better understanding look at the following code:

The Click-Event works for both components. But the DoubleClick-Event is only handled by the Panel-Component.

I have a custom component on which I have bound an array collection to one of its proeprties: <comp:MyComp id="comp" prop="{images}" /> images is an arraycollection In the components' code I would like to know which event to listen on everytime images updates props. I tried a setter on props but the setter only gets called once when props is first set. I tried the collection event but I get "Update" events sent on top of 'add' and 'remove' events and I would rather not have to manage those. So is there an event(flex or otherwise) that is fired every time a component property is updated by a bindable property?

I have an event listener for a custom event type. This custom event overrides the clone method as required.In this event listener I want to dispatch an instance of a different type of event... a different custom event instance altogether. It also overrides the clone method as required.The problem is I'm getting a type coercion error: TypeError: Error #1034: Type Coercion failed: ...I do not know what is trying to do the casting. My code is:
/* elsewhere in a method */
addEventListener(GestureEvent.GESTURE_SCALE, handlePinched);

I want to add an event listener to each component inside a repeater, but don't know how. Here's some code I have tried:
<mx:Repeater id="rp" dataProvider="{dataProvider}" width="100%">
<mx:Button id="attach" creationComplete="addListeners(attach[rp.currentIndex])"/>
</mx:Repeater>
This doesn't work. creationComplete is not called until the repeater has finished instead of (as I expected) when the creation of the button is complete. I'm not sure how to accomplish this.
BTW - I also tried placing the creationComplete on the parent component to the repeater, but it would only be called the first time the component was rendered (the data inside the repeater sometimes changes) so that didn't work.

I have a class which makes a url request and stores data from that request. When the data is retrieved, parsed, and stored into an array, I'm sending a dispatch event which I listen for in my document class. In the event handler function in the document class, I'm accessing the array that was compiled from the class. The array inside the class has 15 values, however in my event handler function, I'm only retrieving one value from it, which is the last value in the array. I posted my code below. Is there a different way I'm supposed to use the dispatchEvent in order to retrieve all of the array values instead of one?

import flash.display.Sprite;
