In Flex, is it possible to listen to all event types of an object that's an IEventDispatcher? addEventListener's first parameter is the type, which is a string. In many cases the documentation is not clear what event type it fires. I'd like to attach a generic listener to inspect the events.

I'm having the following problem: I've implemented a custom headRenderer for my DataGridColumn. The idea is to have a dropdown menu when clicked on the column header. The problem is I don't know how to add a listener or pass a variable to the renderer since the renderer class is instantiated by the ClassFactory.
The renderer class:

The event from the function is dispatched correctly... I can't intercept it..
I am trying to figure out how to override the default paste logic in a Flex 4 DataGrid ItemRenderer. Does anyone know how to do this?I am trying to capture the event when a user hits Ctrl-V while a cell in the DataGrid has focus and override the logic there.
View 1 RepliesI have a simple drag and drop, and wanted to change the state of the drop target on a match. It works as expected, but then there the state changes back to normal (or the itemrenderer is refreshing). I am guessing there is either an override that i need to do, or in need to flag it to not refresh, but having no luck.

View 2 RepliesI have a Tree, which has an itemRenderer. On the itemRenderer, driven by the XML conditions, objects are created dynamically and added as a children to nodes. These new objects shall trigger an event handler ( some click events mostly ). How do I pass the event handler to the tree and later to the dynamically created new objects inside itemRendere?
Something like:
<mx:Tree x="534" y="49" newObjectsOnClick="newObjectsOnClickHandler">
I am trying to learn JavaScript and I am wondering whether JavaScript has a event listener just like ActionScript's ENTER_FRAME. Basically, I want this event listener to listen "all the time" not just wait for any particular instance (mouse click, keyboard event) of event.
View 3 RepliesI know the difference between the two, but I never felt the need to use the bubbling feature. If I want to listen to an event from a deeply nested children, I always use the capture phase. Could someone explain to me why I should rather use bubbling, its advantages, and maybe show me a situation in which bubbling would be the only solution?

View 2 RepliesI have two buttons that listeners for the same event that have identical instance names?For example, I have two buttons which have the same instance name: imageOne.Can those identical buttons listen for the same event? I tried, but only one button responds to the event listener .why do I need two buttons with the same instance name that listens for the same event?because I have a looping scrolling panel of thumbnails, and when you have scrolling panels, we all have duplicate panels inside for looping purposes...so since I have to have two identical panels grouped together to do the loop, I have multiple buttons with the same instance name.and these buttons listen for events...now of course I can rename the other half of the identical buttons with different instance nams, but a problem arises when i want to use an if statement to check to see if that image is already loaded.for example, say I image1 is already loaded, and someone clicks identical thumbnail that has a different instance name, ti would be too complex to write an if statemen to determine whats loaded.
View 4 RepliesI know there's been quite a few posts about events, but I've run into a problem that I haven't really encountered before, and I've kind of confused myself with all the talk of "bubbles" and "capture" and various complexities of creating custom events, etc...Anyway, I'm trying to figure out how to dispatch a global broadcast style of event.1) If I have a custom class that resides in the Display List (the DispatcherClass), how do I set up this class to broadcast a "global" event?Actionscript Code:1b) If I have another custom class that also resides in the Display List (but in a completely unrelated heirarchy), how do I get this ListenerClass to "hear" the event WITHOUT explicitly referencing the instance of the DispatcherClass like so:
Actionscript Code:DispatcherClassInstance.addEventListener("DispatcherClassEvent", handler, false, 0, true);Is this even possible?2) What if the DispatcherClass DOES NOT reside in the DisplayList?Is it possible to dispatch a "global" style event since there is nothing to "bubble" up through?2b) How would I get a ListenerClass, maybe on the DisplayList, maybe not, to "hear" this event?
I am trying to create a text effect using a custom class. The class receives refferences to the TextFields that I want to apply the effect to, an the effect should take place whenever the text is changed in these TextFields. The problem is that Flash doesn`t seem to provide a way of listening for the TextField.text event of a Dynamic TextField... Or does it? Just to clarify: On the stage I have a dynamic TextField named tText. I create a new instance of my class and call MyClass.addTarget = tText, which is supposed to tell my text effect class that it should apply the effect to tText, whenever the .text property changes.
PS: What I have tryied was TextEvent.TEXT_INPUT, but apparently that`s for Input TextFields, whenever the user inputs some text. I change my text through code. I have also tryied Event.CHANGE, but that doesn`t seem to work either...

View 3 RepliesI'm using a electronic device to dispatch events within AS3.
short explanation: -->
Think of these events as a KeyboardEvent.My point is to dispatch an Event (like a Key that is being pressed) so I can listen to this event on EVERY Class I need to.I'm not sure how to instantiate or listen to these events correctly =/
I mean: I want to be able to listen to the key that is been pressed as if that was a global event every Class can receive...
long explanation: --> I'm doing something like this:
1) created a (main) Class that extends a Sprite.
2) created a class (KeyboardInput) that extends the main class.
3) created a class (KeyMap) that extends EventDispatcher.
4) created a class (HomeScreen) that extends a Sprite.
My FLA file is associated to the KeyboardInput Class.This Class creates a listener for the KEY_DOWN KeyboardEvent and instantiate the KeyMap Class that dispatches a CustomEvent:
stage.addEventListener(KeyboardEvent.KEY_DOWN,function(evt:KeyboardEve nt):void { keymap = new KeyMap(); keymap.setKey(String.fromCharCode(e.charCode)) });[code].....
I've got 3 classes: The class that recognizes the change in URL (using SWFAddress by Asual):

And the "Hello World" never appeared in the output window - so I'm not sure if is it possible that my MenuPanel has a chance to receive a info about completing the validation triggered by some other class?

I'm new to flash and programming in general but am learning it to make games. I'm currently messing around with hit detection and its not to hard to test in the game tick ( fired from onEnterFrame). What I'm wondering is if it would be possible / useful to create a custom event that i can listen for. And make the eventListener hear when a collision happens. Also would this be better or worse for the cpu than testing the collisions of lots of enemies on a screen?

View 2 RepliesI have an as3 class with an embedded swf. I need the embedded swf to dispatch an event and have the as3 class action on that event. This used to work fine when the embedded swf was embedded and had been loaded as an external swf, however now that it's embedded the listener never picks up on the dispatched event.
I've created a simplified example below, the 'onMovieComplete' function is never called.
/* I have an external swf file 'movie.swf' with a simple animation in it.
* When the animation hits a frame (frame 70 in this case) it fires a
* Event.COMPLETE (using:- "this.dispatchEvent(new Event(Event.COMPLETE));" )
*/
[Code]....
why the event dispatched from the embedded swf is never picked up by the listener?
