Flex :: Dispatch Event From Application To Module?
Mar 29, 2010Is 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.
Flex :: Unable To Dispatch Custom Event In Mobile Application
Nov 10, 2011I 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 {

Actionscript 3 :: What Is The Order Of Event Dispatch In Flex 3?
Jul 10, 2009I 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?
Flex :: Dispatch A Click Event At The Top Of A Loaded .swf?
Jun 15, 2010So 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?
Flex :: Dispatch An Event From A Class That Inherits From EventDispatcher?
Nov 23, 2009What 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.
Flex :: Dispatch An Event In A Flash Swf That's Loaded Via SWF Loader
Feb 23, 2010I'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.
Flex :: Manually Dispatch A Collection Change Event?
Mar 14, 2011I 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.
Flex :: Dispatch Event To Popupmanager Without Reference To Instance?
Apr 25, 2011I'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.
Flex :: Dispatch Event When Popup Brought To Foreground?
Apr 28, 2011Is 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.

Flash - Listener In Main Document Class For Custom Dispatch Event From Another Class Does Not Respond Or Call Function?
Apr 1, 2011I have a document class called Main.as In the class constructor I have the following listener:

Flex :: Propagating Event From A Built-in Component To A Custom Event?
Jan 27, 2012I 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?

View 1 RepliesIDE :: Flex Application As Custom UI Component
Dec 22, 2009I'm making a UI for a component in Flash. I wanted to use Flex and have had no luck getting the onUpdate exernalInterface call to fire properly. I'm referencing the functionality described here: [URL]. First off, I can't embed the SWF in the FLA. It just won't start the Flex SWF. Even using the external swf, it seems that the onUpdate function is either called too early or not at all. Here's what I've tried:
Tying the externalInterfce declaration to the initialize, preinitialize, applicationComplete, and creationComplete events. Sub-classing my application and putting the externalInterface in the constructor. Neither of these options work. When I create a basic AS3 project in Eclipse and put the externalInferface in the constructor, it works as expected.
