I have created a custom even class which is pretty basic. But when calling an event and then relaying that event to another class I have encountered the "cannot transform thisEvent into thisOtherEvent" error. I realize this is because I needed to override the Clone function in my custom event like so:
[Code]...
I have seen this done and not done on different occations... why do we need to override clone() and toString() in custom events?
I always have a question about override custom event. I am not sure why or what do to inside override function. I searched google but didn't get too many feedbacks. EDIT: My projects seem work fine even though I use my custom event without override. Anyone could explain it?
View 2 RepliesThis 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;

Is there a point of creating custom event class if i dont need to pass custom property with that event?
View 3 RepliesI want to clone an object of a class (whose source code I do not have) and copy all of the associated event handlers from the original object to the new cloned object. Does anyone know how I can do that? I know how to copy the properties from the original to the new, but can I iterate over all the event handlers and add them to the new object?

Is it possible to override the default focus event on the in-built TextField class? So for example when a textfield gains focus a custom event is triggered rather than the default one? I know we can use the onSetFocus event, however we have over 1200 swfs that use TextFields so want to do it on a global scope rather than having to modify each individual swf. that on an Android tablet selecting a TextField brings up the android keyboard that not only shrinks the flash content, but defaults to the alpha keyboard when all we want is numeric (it's a Maths app).

View 1 Repliesoverriding clone() while creating custom events?I read in the Flex cookbook that we need just in case we want to redispatch this event. Does this exactly means that when we want event to be bubbled up the display hierarchy , at that time our custom cloned event should be dispatched and not the Event object.
second - whats the need of metadata tag -
[Event(name="modelEvent", type="com.abc.data.model.ModelEvent")]
public class LoginModel extends EventDispatcher
I understand we need to extend EventDispatcher in case we want to dispatch evnet from class.. but In what cases i would need to specify the MetaData TAg
Third is.. If i write -- "dynamic customEventClass extends Event".. Is there any use of Dynamic i can make?
i am trying to do a simple blackboard on mouse down, start drawing on mouse move, if drawing, draw line on mouse up, stop drawing i set the listeners on a simple clip with a rectangle. if i dont fill the rectangle, the mouse events wont fall into the rectangle, but if i fill the rectangle, it will paint behind the rectangle, so anyway i wont see any succesfull results. what i did was create another sprite and paint within it; something like

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 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 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):

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.

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 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?

ActionScript 3, just learning AS3 but know a handful of other languages. What would cause an event that the listen call executes without throwing an error and was successfully dispatched, to not be listened to?
Dispatch call (this runs ):

if ( m_MouseState == MOUSE_STATE_SELECTED )
m_MouseState = MOUSE_STATE_NONE;
else {
m_MouseState = MOUSE_STATE_SELECTED;

The "Squares" are childed to a checkerboard that is childed to my main app ( which extends sprite ). the checkerboard displays and has all the behaviour I want, but when I click a square, the click event fires and dispatches the custom event, but the custom event is never received. That should be all code needed, the rest of the code is just to create a grid and put random numbers in the squares, which works fine. According to every website that has a "custom event tutorial" it would appear that i have everything needed to listen to the event, its just not happening.
