[flexcoders] Events and Inheritance
I am still confused about how to make an event come through to an inherited class. For example, in Container.as there is a scroll event. Canvas directly extends Container. When I add canvas inside MXML I can handle the scroll event because it comes through from Container to Canvas. However, I have an example where I have a base component that dispatches an event. When I add an inheriting component to MXML, I can't see the event being dispatched by the base component. Or at least I don't get code hints like the above scroll example. Can anyone explain this to me? Thanks! Jake Churchill CF Webtools 11204 Davenport, Ste. 100 Omaha, NE 68154 http://www.cfwebtools.com http://www.cfwebtools.com 402-408-3733 x103

i have an array collection that populates a gallery. my arraycollection is in turn populated when i click an item in a tile list, so whenever i click on a new item in the tilelist, the data for the array collection is supposed to change but nothing seems to change. any help?
[flexcoders] Events and Child SWFs
Hi guys,
I've got a parent application with a 'delete' button. When it's
clicked, I want to set a flag in a child swf, which is loaded via SWF
loader.
So in the parent app on the button's click event I'm dispatching an event:
dispatchEvent(new Event(inDeleteMode));
In the child SWF's init function I've got this:
this.addEventListener(inDeleteMode, deleteModeHandler);
And then the deleteModeHandler function (stubbed in for testing):
private function deleteModeHandler():Boolean
{
Alert.show(got it!);
return true;
}
It ain't working. Can someone see what I'm doing wrong?
Thanks,
David
Re: [flexcoders] Events and Child SWFs
You are assigning the listener to the wrong object. this is your child
swf, but it is the parent that dispatches the event. Depending on the rest
of the app this.parent might work. So:
this.parent.addEventListener(inDeleteMode, deleteModeHandler);

RE: [flexcoders] Events and .dispatchEvent();
The key thing here seems to be that code that is expecting a (custom) fault event is getting a (custom) result event instead. You need to figure out how that can happen in your code.

[flexcoders] Events and performance
I was wondering if I could get some input about events and performance. The exact situation I have is I'm using the HashMap class from Copyright (c) 2006 Eric J. Feminella. I've modified the class so that on put/remove/clear/reset functions it will dispatch a dataChanged event. This way I can set listeners on the class. This will obviously create many events. We use this class in several places in our app, but only a couple need to listen to changes. Will this create any type of performance issues since the bulk of the HashMap instances will be dispatching events that nothing is listening to? I'm not sure if Flex is optimized to see that an event is being dispatched that nothing is listening to so handle it efficiently. The other choice I was going to make was to modify the HashMap class and remove the final from the class. Then extend it to a ManagedHashMap class and have the HashMap not dispatch, but have the ManagedHashMap dispatch. Looking forward to hearing some other input. Thanks, Dale

[flexcoders] Events in AS3 gives Compile Error 1119
Hi Flexcoders,
I#8217;m having trouble with some advanced features of flexthat involve
events, custom datagrid components, and item renderers. Basically, I#8217;ve
been following along #8220;Thanks Mister#8221; blogwhich shows how to bubble
an event to a parent control. In the blog tutorial,there is a list control,
and one of the columns has a button, so when a userclicks the button a menu
appears, and then which ever menu item is selected bythe user triggers a new
event to be dispatched and bubbled up to the parentcontrol.
http://thanksmister..com/?p=68#comment-5836
In my situation#8230;.
1.) I have a custom DataGrid object, which has metadatatag:
[Event(name=menuClick,type=mx.events.MenuEvent)]
2.)I have a custom datagrid ItemRenderer, thatknows how to bubble up the
menu event to the parent custom datagrid control
3.) There is an event handler function inside the mxmlfile that has an
instance of the datagrid object.
My Problem:
For some reason when I use mxml to connect the event handlerfunction with the
custom datagrid control I can get that to work; however, whenI try to use AS I
get a compile Error 1119: Access of possiblyundefined property MENU_CLICK
through a reference with a static type Class.
Here is the mxml that works:

handleMenuEvent(event:MenuEvent):void
{ Alert.show(#8220;menu Event#8221;);}
]]
/mx:Script
local:CustomDataGrid id=#8221;mycustomdg#8221;
menuClick=#8221;handleMenuEvent(event)#8221;/
Here is the AS that does *not* work, I put thisinside the initApp() function
and I get a compiler error, 1119:

Hi Michael,
Thanks for the info, I was actually getting confused with allthe various event
names. You are correct, there is no MenuEvent.MENU_CLICKevent which probably
explains the compiler error.
I tried to use MenuEvent.MENU_CLICK after reading the blogtutorial. I believe
using #8220;menuClick#8221; in the MXML works becausethe custom datagrid obj.
that was used has metadata tag at the top of the classdefinition that specifies
a new event, named #8220;menuClick#8221; that isfor all MenuEvents.
[Event(name=menuClick,type=mx.events.MenuEvent)]
Public class CustomDataGrid extends mx.controls.DataGrid
{
Public function CustomDataGrid():void{ super();}
}
However, trying your suggestion I changed
MenuEvent.MENU_CLICK to MenuEvent.ITEM_CLICKin the AS I started getting runtime
errors. Saying
Error 1034: Type Coercion failed: cannot convertmx.events.ListEvent to
mx.events.MenuEvent
I#8217;m sending this back out to the flexcoders community toget their input
as well. I appreciate your assistance.

[flexcoders] Events and Non-Display Objects
General question here... I understand Event flow with objects in the display list. They flow either up (bubbling) or down (capture) between parent and child. Maybe an oversimplification but my question really is about how to handle events with objects that are not in the display list. How do you pass events from them? Like for instance, I've got this situation here... I have an MXML that is just an mx:Object. It's MXML because I'm defining some remoteObjects in it and that's just way more fun to do in MXML than in AS. So anyway, regardless, the methods inside are static and I don't want to draw the thing. It just needs to hang out and be available so I can make these remoting calls. So there's the rub. How can this MXML talk back to where it was called from? Can I use events for this or do I need to send a callback function? Any wisdom here would be awesome... this has been befuddling me for a while. -b

RE: [flexcoders] Events and Non-Display Objects
You can adopt the following two options to achieve your requirements. 1. Your MXML Object should Implement the IEventDispatcher interface and internally it creates an instance of EventDispathcer class and delegates calls to that instance. 2. If you dont want to use built-in event dispatcher and you want to define your own function definition, then you can defines an interface and all the listeners should implement that interface. Moreover, you should methods in your MXML Object to register and unregister those listeners and call the specific method of that interface on some condition. Gordon, I want to ask you a few questions regarding event dispatching mechanism of default EventDispatcher. 1. Does EventDispatcher calls the listeners synchronously or asynchronously? 2. Does the EventDispatcher make copies of the event object provided to EventDispatcher's dispatchEvent function when calling the listeners? Let say, I define 2 listeners for specific event type. The first listener modify some properties of the event object. Do the second listener get the modified one or the copy of the original one? --- Gordon Smith [EMAIL PROTECTED] wrote: Or your Object subclass could create an EventDispatcher instance which can dispatch events on its behalf: var eventDispatcher:EventDispatcher = new EventDispatcher(this); eventDispatcher.dispatchEvent(event); Gordon Smith Adobe Flex SDK Team From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Alex Harui Sent: Wednesday, November 28, 2007 1:26 PM To: flexcoders@yahoogroups.com Subject: RE: [flexcoders] Events and Non-Display Objects You can try extending EventDispatcher and dispatch events From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of bithroop Sent: Wednesday, November 28, 2007 10:18 AM To: flexcoders@yahoogroups.com Subject: [flexcoders] Events and Non-Display Objects General question here...

RE: [flexcoders] Events and Non-Display Objects
Does EventDispatcher calls the listeners synchronously or asynchronously? Synchrously, in the order that they were added. To see that the handlers execute before dispatchEvent() returns, add a handler which traces out something and single-step in FlexBuilder or fdb over a dispatchEvent() call. You should see the trace output. BTW, I may be the only person in the world that distinguishes between a listener and a handler. A listener is an object that is interested in knowing about an event dispatched by another object, while a handler is a method of the listener that executes in response to the event. The name addEventListener() is somewhat confusing. You might think that you'd have to pass it both listener and a handler (to tell it which method to execute, and which object to use as the method's 'this'), but due to the magic of method closures, you only need to pass the handler and it implies the listener. Does the EventDispatcher make copies of the event object provided to EventDispatcher's dispatchEvent function when calling the listeners? Let say, I define 2 listeners for specific event type. The first listener modify some properties of the event object. Do the second listener get the modified one or the copy of the original one? The second listener gets the modified event instance. A copy doesn't happen in this case. However, when an event handler calls dispatchEvent() to redispatch the event in the middle of event processing, then dispatchEvent() close the event's clone() method to copy it and redispatches the copy.

RE: [flexcoders] Events and Non-Display Objects
Thanks Gordon for you prompt reply. Gordon, my experience is somewhat different that what you explained. As per my experience, I feel the handler functions of listeners are called asynchronously in the order the handlers were registered. By synchornous, I mean if the handler of the first listener calls a blocking function or perform some time consuming calculation (let say runs a for loop for 500 times) then the handler of the second listener will not be called unless the handler of the first listener returns. I have tested it by a couple of techniques. 1. Handler function of first listener displays an alert and then iterates for 500 times (performing some useless tasks like modifying the same property of the object). Handler function of second listener simply display alert. Both alert message boxes are displyed at the same time even though the first handler is still inside the for loop. 2. Here I apply the break point on the first instruction of handler functions of both listeners. The functionaly of handler functions are the same as expained in above. The debugger break on the instruction of first handler and then I press F8. The debugger then breaks on the instruction of the second handler, however, the first handler function is still inside the for loop. Can you still confirm that eventdispatcher invokes the handlers in synchronous manner? I am implementing a publisher-subscriber scenario using EventDispatcher and the desing decision will be highly affected by the behavior of deafault EventDispatcher. --- Gordon Smith [EMAIL PROTECTED] wrote: Does EventDispatcher calls the listeners synchronously or asynchronously?

executing. And when I set breakpoints on the three t.text assignments in
both handlers, I hit them in the expected synchronous order.
Both alert message boxes are displyed at the same time

They're displayed at the same time because the Flash Player doesn't

Subject: RE: [flexcoders] Events and Non-Display Objects
Thanks Gordon for you prompt reply.
Gordon, my experience is somewhat different that what
you explained. As per my experience, I feel the
handler functions of listeners are called
asynchronously in the order the handlers were
registered.
By synchornous, I mean if the handler of the first
listener calls a blocking function or perform some
time consuming calculation (let say runs a for loop
for 500 times) then the handler of the second
listener will not be called unless the handler of the
first listener returns.
I have tested it by a couple of techniques.
1. Handler function of first listener displays an
alert and then iterates for 500 times (performing
some useless tasks like modifying the same property of
the object). Handler function of second listener
simply display alert. Both alert message boxes are
displyed at the same time even though the first
handler is still inside the for loop.
2. Here I apply the break point on the first
instruction of handler functions of both listeners.
The functionaly of handler functions are the same as
expained in above. The debugger break on the
instruction of first handler and then I press F8. The
debugger then breaks on the instruction of the second
handler, however, the first handler function is still
inside the for loop.
Can you still confirm that eventdispatcher invokes the
handlers in synchronous manner? I am implementing a
publisher-subscriber scenario using EventDispatcher
and the desing decision will be highly affected by the
behavior of deafault EventDispatcher.

Synchrously, in the order that they were added. To
see that the handlers
execute before dispatchEvent() returns, add a
handler which traces out
something and single-step in FlexBuilder or fdb over
a dispatchEvent()
call. You should see the trace output.
BTW, I may be the only person in the world that
distinguishes between a
listener and a handler. A listener is an object that
is interested in
knowing about an event dispatched by another object,
while a handler is
a method of the listener that executes in response
to the event. The
name addEventListener() is somewhat confusing. You
might think that
you'd have to pass it both listener and a handler
(to tell it which
method to execute, and which object to use as the

due to the magic of method closures, you only need
to pass the handler
and it implies the listener.

The second listener gets the modified event
instance. A copy doesn't

[flexcoders] Events, itemRenderers, and the horizontalList control
I have been trying to figure out how to do something and have finally
reached wits end today. I must be missing some fundamental
understanding of something between events, itemRenderers, and the
horizontalList control... I am very new to itemRenderers, so I suspect
this is where my problem lies.
Here's what I'm trying to do. For the sake of example, I would like to
have a horizontalList control that gets dynamically populated with
n-number of interactive controls (all of the same class - for
simplicity's sake, I chose a list control.) So basically, click on a
button (or other event) and dynamically add a new List control to the
horizontalList's dataProvider. In order to do that, I have to tell the
horizontalList how to display the new control, which (unless I'm
mistaken) requires an itemRenderer.
Once those dynamic controls are created I need to operate on them
independently, so I'm trying to add an event listener to each of those
controls as they are added. Seems easy enough using a call to
addEventListener at the time the new dynamic List control is created,
and I can even trap that event in the itemRenderer (or, so I think), by
adding a generic on change event handler in the itemRenderer which, in
turns, re-dispatches the original event...
I think this may be where I'm going wrong, however I'm at a loss on how
to achieve what I'd like to accomplish otherwise.
The problem is, the event listener that I added when the dynamic
component was created isn't being recognized, or I'm placing the event
listener on the wrong component. The event from the itemRenderer
apparently fires, however it's not heard by the main application.
Any assistance you guys can provide would be hugely appreciated, I've
been banging my head on the desk for longer than I care to admit on this
and I'm still missing something...
Thanks in advance,
Brian

RE: [flexcoders] Events, itemRenderers, and the horizontalList control
Renderers get recycled. Have you read my blog articles
(blogs.adobe.com/aharui).
Normally, you add data items to the collection and the list responds by
creating renderers from the itemRenderer factory. You are adding Lists
to the collection and they aren't the lists that you see in the UI which
is why they don't send events. Normally the renderer dispatches an
event off the .owner property so you can listen to it from the List.

[flexcoders] Events in AS3 Classes
I know that I can write my own custom event class, but I was wondering about something that seems to be undocumented and that seems to initially be promising: When adding a meta tag to an AS class such as: [Event(name=myEvent,type=flash.events.Event)] the event shows up when using the class by creating an event listener. The interesting thing is that code assist picks it up, but it shows up with an altered signature: myClass.addEventListener(Event.MY_EVENT,myEventHandler); I wasn't able to find any documentation on it. So I am wondering if this would actually work. At the moment I'm not able to fully test it, as the compiler throws an error with my static class (defined as a singleton) stating: Error 1119: Access of possibly undefined property MY_EVENT through a reference with static type Class. If this is legal code, then the question would be how to 'define the property' so that the compiler is satisfied. Does anyone have more information on this? Thanks, Jurgen
[flexcoders] Events not firing from swf imported with SwfLoader
Hi, I'm not a flash expert so you'll have to bear with me on this. I'm not creating the swf's myself. I've recieved animations in swf's before and used them in image controls and they work fine. (movie clips generated in Flash MX 2004) If however the swf has a button on it (just an animation which plays on the rollover and snaps back to first frame on rollout) no events get fired from it when it's embeded into my image control. I'm assuming that the button in the swf is catching all mouse events and not passing them on. Does anybody know if this is the expected behaviour or if there's an easy way around it? As it stands I guess I'll need to handle switching to an animation on the rollover event within Flex2. Thanks in advance Bill P.S. I saw this, but it seems like overkill for what I want. http://www.jessewarden.com/archives/2006/08/flash_9_button.html

Re: [flexcoders] events
What about keyListeners? How can I implement a KeyListener, because when I run the following code, it errors trying to access the Key variable. Lines 3 6. This statement is not permitted in a class definition.
var keyListener = new Object();
keyListener. {
x = Key.getAscii();
trace(You hit: + x);
};
Key.addListener(keyListener);
Thanks again!

RE: [flexcoders] Events again...
Sidenote: instead of subclassing EventDispatcher directly you can also
use the IEventDispatcher interface. This way you don't need to derive
from EventDispatcher:
// pseudo code
class Foo implements IEventDispatcher
{
public function Foo()
{
dispatcher:EventDispatcher = new EventDispatcher(this);
}
// later
public function dispatchEvent(event:Event):Booleen
{
return dispatcher.dispatchEvent(event);
}
}

dispatchEvent and addEventListener are methods of the
EventDispatcher
class. EventDispatcher is the superclass to most (all?) built
in flex
components, but is not inherently available to all AS3 classes.
If you modify ClassB to instead be
public ClassB extends flash.events.EventDispatcher, it should
run as expected.

For addeventlistener I beleive you need a handle of the object since sib2 does not have the handle for sib1, I will not be able to dispatch and receive the event.

Re: [flexcoders] Events and Components
You can bind to the result from the GetResults function directly, flex
takes care of generating the binding code for you. (no need to dispatch
events)
E.g.,
mx:ComboBox dataProvider={this.parent.Webservice1.GetResults.result}/
Or, if you need to invoke a method with the results
mx:ComboBox
dataProvider={myFunction(this.parent.Webservice1.GetResults.result)}/
define your operation like:
mx:operation name=GetResults/

RE: [flexcoders] Events and Components
In 1.5 the web service doesnt
cleanly support adding event listeners at runtime, youd need to do it at
compile-time through the tag (this is changing in the next version). But you
could delegate this work if you wanted by using something like a Responder as
mentioned in the Cairngorm framework and the iteration::two book.

I'm not sure if this'll work, but try passing the
result object as a
part of the GetResuts event. So in your
doSomething() you get the
event object which contains the result object.
