how can i add an event listener to detect when the height of a DisplayObject changes.
Obviously, Event.RESIZE doesn't work.
should i make a new custom event? i don't know how to slip the "height change" in the custom event..
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;

I using the SSP component, and I scripted a custom event for clicking on loaded images to go to the next image.This is working very fine except for that the hand-cursor won't show up on roll-over on the image.I'd like this to happen, but dont't know how to.This is ths scrip I use now:
listenerObject = new Object();
listenerObject.onImageClick = function(eventObject):Void {
my_ssp.nextImage();

Is there a point of creating custom event class if i dont need to pass custom property with that event?
View 3 RepliesI would like to use a movieclip to load a flv video. The problem I have is that I want to change the video dimensions. I've tried several software to change the video dimensions but as far as it seems all of them keep the same height-width ratio than in the original video. Is there any software that would allow me to change the height and width without keeping the same height/width ratio as in the original video file?
View 3 RepliesI 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):
<?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.
package com.events

import flash.events.Event;

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?

View 10 Repliesi am trying to add the height and width of swf dynamically but i cannot change stage.stageWidth and stage.stageHeight and also am tring with another method also.
[SWF( width="900", height="400")]
Its working fine but while adding the value dynamically it cannot change.

var wid:Number=300;
[SWF( width=wid, height=hei)]

I'm trying to edit an HTML that uses swfobject to load a flash file.
What I'm trying to do is to reduce the size of the SWF file.
I've tried editing the height and width parameter within the swfobject(), but that didn't work.
I tried reducing the width height in the HTML css, but that also didn't work..
How can I pass a 'width' or a 'height' parameter to the swfobject so it will actually load the swf in a smaller or 'zoomed out' way?
I have an html page that loads a swf that loads an AS 3 animation with 4 dozen 60k jpgs that rely on the tween class to move them across the screen.
I'd like to start the empty stage at 10px, and after the jpgs load, animate the height to 142px, pushing down the html underneath and run the parade.
It�s suppose to change the height of a box that is containing some text, and I just want it to go from one state to another using simple AS. Is that not possible ?
btn_small.onRelease = smallRelease;
btn_Big.onRelease = bigRelease;
function smallRelease() {

I am displaying a combo box in something of a WYSIWYG preview. I want the user to be able to click on the combo box and see the options inside, but I don't want them to be able to change the value. I tried using preventDefault() on the change event but it doesn't work. I don't want to disable it because I do want the user to be able to "look inside" the dropdown.
So I'm trying to block the change, but can't. My next resort is to change the selected index back to what it was before the change, Is there any way to do this within the scope of a ListEvent.CHANGE event listener?
Current Workaround is to basically re-assign the controls selected item the same way I am defining the selected item when I originally build it (a default selection). So a user sees their change then it immediately changes back to the default selection.
