I created a new CustomEvents object which I want to use to let the main class located in .mxml file to know about an event which had finished it's work in Crop class. However when I dispatch a CustomEvent from Crop class I can not catch it in my main .mxml file's class.
CustomEvents class
Code:
package actions
{
import flash.events.Event;
public class CustomEvents extends Event
[code]....
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]...
I registered a very simple button event listener in A.mxml:
<mx:Script><![CDATA[
import mx.controls.Alert;
public function Handler():void
[code]....
It works fine when clicking the button everytime.Now I want to have something interesting,that is,I want to capture this buttonClick Event in another mxml file,say B.mxml and do something in B.mxml instead of A.
I am testing timerevent with flex unit. Follwing is the code which i tried ,it always goes to cmdFailed function (Time out function).I am new to flex unit.[code]
View 1 RepliesI 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 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 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.

import flash.events.Event;

View 3 RepliesI 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 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?
printableInvoice.addEventListener(batchGenerated, printableInvoice_batchGeneratedHandler);Results in this error: 1120: Access of undefined property batchGenerated. I have tried it as FlexEvent.batchGenerated and FlashEvent.batchGenerated.
The MetaData and function that dispatches the even in the component printableInvoice is all right. It I instantiate printableInvoice as an mxml component instead of via action-script it well let put a tag into the mxml line: batchGenerated="someFunction()
Is there a point of creating custom event class if i dont need to pass custom property with that event?
View 3 RepliesIn IE, if flash has focus, and receives a keydown event, it does not appear to bubble the event up through the DOM (I can't capture the event by listening on document, however the same listener can capture key events from html siblings, so I know my listener is working).
However, some other plugins on the page (I am looking at you windows media player) still respond to key events that initiate in flash (and I need to prevent that from happening)! It seems that the key event initiated in flash takes the bubble express highway straight to the top (where the top is whatever is above document in the DOM hierarchy). I have tried terminating the events in as3, and tried different wmodes... neither approach works.
I came across this annoying bug in Linux.
consider this code as timeline code:
ActionScript Code:
import flash.utils.getTimer;
import flash.events.KeyboardEvent;
[Code]...
(haven't tested in Mac, I deleted my mac vm as it wasn't accurate)
What is going on is that just after a KEY_DOWN event, a KEY_UP event fires, even though you didn't release the key.
Now as for where this bug is located, I'm not sure. It could be with how flash integrates into the already present keyboard interface of the OS, or it could be the OS's keyboard interface itself.
But see either way, it's something I can't control. I can't change flash player, nor can I change the keyboard interface of the OS (well I can, but what about other users with Linux?).
So what I need is a way around this. To side step this key up event when the key up didn't actually occur. Because this is causing some majour issues with my KeyboardController class.
[edit]
furthermore it makes me wonder what might be going on in Solaris.
I think I'll reinstate my vm's of Solaris and Mac OSX and see.

I'm trying to capture keyboard events with the following code. I'm testing in an external popup flash player in FlashDevelop and it ain't tracing anything. I reckon it might be something to do with keyboard shortcuts in the flash player.
But I can't find where to disable them?

I got a question about event dispatching in flex.my goal is to get a custom event loaded up with some data and than bubble up to the eventlistener. my main application has and AMF service request inside which calls an service class. that class is supposed to dispatch an event when the AMF service request returns a result or fault and the main application is listening for that event.so inside my mainapp i add and listener like this:[code]
However, this event never reaches the main application. Looking closely to it with the debugger, i found out that when the event is dispatched the listeners property of it is set to null.
I'm in a Flex Mobile application project. I need to dispatch an event to the lexGlobals.topLevelApplication and it has to contain a custom message. I'm trying to make an object and dispatch it like this:
//create the event Object
var receivedObjMsg:Object = new Object();
receivedObjMsg.name = "receivedMessage";
receivedObjMsg.message = messagevarhere;

I'm trying to dispatch a custom event from a custom ItemRenderer. This is my custom event
package events {
import customClass.Product;
import flash.events.Event;
public class CopyProductEvent extends Event {
public static const COPY_PRODUCT:String = "COPY_PRODUCT";
public var picked:Prodotti;
[Code] .....
The event from the function is dispatched correctly... I can't intercept it..
Is there a way to write a custom event that gets triggered when the user clicks outside of that custom component instance? Basically anywhere else in the main flex app.

I have 2 custom components, which have their own nesting hierarchy ... One is container for another. I have to "familiarize them" with each other. The way I'm trying to achieve that is using global events (one side is firing and the other one is catching):
Application.application.addEventListener("Hello", function (data:Event):void{
// .. some actions
});
[Code]...
Then should be created the connection between container and it's child.
BUT, the only thing I could acheive is passing a reference to the Container in the DynamicEvent. Is there any chance that I could access the child at the event-handler function.
