bubble events up a class tree for none-ui components.I have a structure like this:Controller Unit of Work Child Unit 1 (Raise Event)I would like to handle the event raised in Child Unit 1 in the Controller. I've tried to set the bubble property to true but I've read that this only works for UI components.Is there a way to enable this for custom classes that are not UI components?
View 1 RepliesI'm working on a prototype that would require me being able to read and track the mouse movement over a playing youtube video. The basic code to replicate my problem boils down to this simple test case:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
layout="absolute"
[Code]....
Expected behavior is:
Youtube player loads The label on the top right tracks the X coordinate of the mouse The number should update even when moving the mouse over the Youtube player
So far the program behaves as expected when running from the IDE (tested on both FlashDevelop and FlashBuilder) and even when running the file manually from the output folder. But, alas, when I try to run it from anywhere else than the debug folder (be it another location on my computer or up on a webserver), the Youtube player seems to eat the events.
I don't get sandbox security warnings when debugging (thanks to allowDomain("*")) but I'm running out of ideas on why the program fails once you take the file out of the debug folder.
I am trying to Scale the bubbles within the bubble chart. The problem is, I have no control over the data coming in, and the radiusField values are usually below 0 ( no negative values ) with a max of maybe 2.
I created an ItemRenderer for the BubbleSeries, and tried adding a scaleX and scaleY value on the createChildren method, but nothing happens.
I have a custom event class public class FFTDrawEvent extends Event {
public static const DRAW_EVENT:String = "drawEvent";
private var _param:Array = new Array();

_param = __param;
super(type, bubbles, cancelable);

Both class (Dispatcher & Listener) are Child class of a MXML application. Also listen to the event in the parent MXML application doens't work. Listen to the event in the dispatching class itself somehow works.
I have to feeling that the EventDispatcher class is not the right one to dispatch events to a mxml application or respectivly AS classes, which extend/inherent from a MXML component class.
I've created a base class to house some basic functions I'd like to have across several movie clips in a game I'm making, however, when I link a custom class to the same movie clip I get the message; "The base class will not be used because the class specified is already defined and extends its own subclass. If you wish to use the base class, specify a class name in the Class field that will be auto-generated or enter the default base class 'flash.display.MovieClip' in the Base Class field." I removed the 'extends MovieClip' inside the Class but it still shows the message. Does this mean that I cannot use a custom class and a custom base class on a movie clip?
View 2 RepliesI'm trapping keyboard events on the stage and dispatching custom events through a framework (Mate, though I don't know that this is an important issue), but I'm pretty confused by the scope. The structure is:application (traps keyboard events and dispatches custom event mainPanel (receives dispatched events but mainCalendar (a child element) is null on debugging. Obviously if I try to call a public method on mainCalendar it errors out, even though it's a child of mainPanel. However, mainCalendar is NOT null IF I use FlexGlobals.topLevelApplication.mainPanel.mainCalendar. Outerdocument and parentDocument do not expose mainCalendar either, BTW mainCalendar (a custom component inside mainPanel with public methods. Creation policy is 'all' and it's visible and exists long before I trap any keystrokes at the top level)Could someone take a minute and explain why the mainCalendar is out of scope when mainPanel receives a custom event, even though mainCalendar is a child of mainPanel. Is there a better way to manage the events so I don't have to always address the component via the topLevelApplication?
View 1 RepliesI have written a custom component for drawing a circle in Flex. But When I try to write a click event or mouseDown event for that component, it doesn't work.[code]...
The "Hello" Alert is displayed only at a particular point and guess is, at the point, (175,150) the x, y co-ordinates of the circle. But shouldn't it be displayed wherever I click on the MyCircle component?? how to enable it in that way?
Also the mouseDown function doesn't work for MyCircle,but if have the event for the VBox, the Alerts are displayed.
Basically I am trying to create a string Validator which requests a new language from its controller by dispatching an event upon its creation.
The example below is a straight copy from the Flex3 component explorer - the only diffrence being that I have created the validator as a custom component which dispatches an event upon its creation.
The problem is that my main Application cannot hear the event being dispatched and I don't know why.
Here is the example
MyValidator.as
package components
{
import flash.events.Event;

I am using a custom component within another custom component in a flex mxml application file.Is it possible to bubble events from an inner component to the outer component and handle events in the outer component?
View 3 RepliesI 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.
I am following these direction to the TEE to create a swc for all my custom classes but the swc never compiles. Is there another way of doing this?? [URL]
View 1 RepliesI have an <mx:Application> which contains a <mx:Module>. This module has several child modules. It also has some an instance of a class I have created. I am trying to have a method of this class dispatch an event that can be "heard" by the module and handled. This isn't happening.To be more clear, I am using 'dispatchEvent' to from inside a class method.There is an instance of this class in: mx.core.Application.myapplication.mymodule.myclassIt is the 'myclass.somefunction' that dispatches the event. I have a listener registered in 'mymodule'. Nothing happens when the function/method runs, however.
View 1 RepliesI'm taking my first stab at writing a custom flex 4 component by extending the UIComponent class. Unfortunately, I cannot get the component to respond to any sort of mouse events.I've tried setting mouseEnabled to true is the component, as well as setting mouseChildren to true in the parent (the stage object). It seems whatever I do, my click events can be detected from the stage, but not with the component.Here is my component class:
package components {
import mx.core.UIComponent;

I have to create a custom header for the AdvancedDataGrid component. The custom header must have two buttons in it. The custom renderer must be applied to more than one column.
How I can fire, dispatch and handle events from the custom headers?
I have multiple items in my app that I would like the user to click on.Some items are completely different classes.The classes dispatch events and then when the events are captured, some modifications are done to the transform properties of a loosely coupled display object.I want two separate classes to dispatch the same type of event, since I already have an image class that draws images based on a given url... I want the classes to dispatch the events, but then I think I want the difference to be detected when the event comes along... i.e., I would like to recognize the 'origin' or 'sub-type' of the event. Some sort of if/then logic would suffice.

I have two components being absolutely positioned within a container (they are MapSymbols on an ILOG Elixir map, if that helps). Each component is a VBox with an Image and a Label. Images have functionality tied to the Click event; labels do not.
The problem is when 2 items are positioned so that the label of one is above the icon of another in the z-index, so that the label eats any mouseOver and mouseDown events. Bubbling doesn't help since it bubbles from the label to the vbox to the container, never hitting the lower element. I can't set the vbox to mouseChildren="false", since that keeps the image from getting clicked, as well.[code]...

View 2 RepliesI'm wondering if there is any way to make the bubble sizes scale or resize when the size of the chart resizes. If the bubbles are set to a specific pixel size, it seems as though the size is set and that's it. So, if your chart is large, the bubble is size X and if the chart is small the bubble is still size X. [code]...

I just started to use classes in AS3. I stuck to event handling between classes. That's what I want to do, but don't know how to do it:
1) set up event listener in a child class
2) when this event in the child class is triggered, the child class, the parent class and several other child classes respond to the event.
I'm trying to handle movement of my Hero Class by adding event listeners in my constructor. I'm trying to move my Hero object.Inside my hero constructor, I have:
Code:
//Adding Event listeners
this.addEventListener(KeyboardEvent.KEY_UP, reportKeyUp);
this.addEventListener(KeyboardEvent.KEY_DOWN, reportKeyDown);
this.addEventListener(Event.ENTER_FRAME, EnterFrame);
And then I have functions for each of the events above. For some reason,the event listeners for key up and key down are never being triggered.
