I used a simple technique in a component I wrote called PreloadingImage.
It adds a graphical preloading display to the mx.controls.Image class. 
I used the PopupManager to get this functionality.
If you you need to add a throbber to an Image you can use this component
(open source).

The component sample app is here:
  http://strawberrypixel.com/blog/flex-components/#preloadingimage

The component tutorial that shows how to do this is here:

[flexcoders] How can I avoid jumping / flickering when changing the dataprovider in a list box?

[Anzer]

Hi,

I am programmatically changing the values in an array collection which is
the data provider of a list box. 

When I change the values the list box is flickering, how can I avoid it?

 

My intention is to show an interface like windows explorer. I want to do in
place re naming and deleting in the list. 

Its working correctly but I want to remove the jumping of the list box items
after the edit.

 

Thanks

[flexcoders] tweening an iframe container

[elr]

Hi all,

I place instances of iframe component (the Alistair Rutherford's 
version of the C. Conraets's component) ) into a tabnavigator itself 
into a panel
It works nearly perfectly (thx to Alistair's help) but as you can 
check by yourself, after some moves mixed with some tab switching, It 
fails to refresh the iframe area ( say containers located to the 
right whereas iframe content stay at the left !!?!!)  I can't even 
determine after which sequence it appears but it always appears after 
somes clicks...)

It sounds that some event handlings are still missing but I have no 
idea which ones..

Your help would really be helpful.
Thx!

I don't exactly know what is going wrong, because I haven't been able 
to find the most current debug player.  Every link I can find that 
should lead to it goes to a regular player dated somewhere around June.

It seems to me that if I am going to add extra lines declaring 
variables of all the easing types, I might as well hard-code switch 
case statements, as it is just as verbose and non-extensible.  Is there 
a more elegant way to tell Flex that it needs to link it in?

Re: [flexcoders] Re: Reflection -- Accessing private fields

[Aaron Miller]

What about making the properties protected and extending the class down into
a "reflector" class which is used to spy on it's parents? To get a true copy
of the original, couldn't you also access the protected properties though an
instance of the parent class? I know you can access the private properties
in an instance of the same class, so wouldn't this also be true for the
protected properties of a parent? Just an idea, haven't really tried this
myself.

You don't say what's going wrong, but I suspect that
getDefinitionByName() is returning null when you pass it a string like
"mx.effects.easing.Cubic". That's because the Cubic class doesn't exist
in your SWF... the MXML compiler has no way of knowing that your app
needs it, so it doesn't link it in. One way to get it to be linked in is
to declare a static var of that type. Note that simply importing it is
NOT sufficient to link it in.

Yes, I had seen that, which is why I made sure I mentioned that I was

if I could find a way to use this as just a generic easing explorer

This is aggravatingly difficult to do...at this point it would have 
been far faster to just do a swich case and hard-code in all the 
easing functions. Not very dynamic or extensible, though, which kind

i have had this same issue, and it's when i use bitmap graphics in flash
with scale-9, apparently it doesn't work that way, only on vector
graphics in flash.  what i do is reference the graphic file directly in
css, and also specify your scale9 grid in css as well.  then it should
work.  or the easier option is to convert your stuff to vector graphics,
but i'm not a graphics guy and have never had much luck with that.

I'm trying to skin panels for use in Flex, but my corners, which are
rounded, keep getting squished. I'm sure I'm doing it right in Flash: My
own drawing is lined up with the reference point (0, 0), the 4
guidelines for scale9 are in the right places and everything. And in my
css file, I have:

Panel

{

  borderSkin: Embed (source="flex_skins.swf",
symbol="Panel_borderSkin");

  borderThicknessLeft: 16 ;

  borderThicknessRight: 16 ;

  borderThicknessTop: 0 ;

  borderThicknessBottom: 16 ;

  headerHeight: 16 ;

} 

Where am I going wrong? Something else I should add, my panel gets
stretched depending on what size I want to make it at, but it looks like
the scale9 stuff is ignored completely, stretching the underlying swf as
if it were just one bitmap with no scale9 stuff.

Try using "undefined" instead of "null". You can also just call

With respect to styles, you can setStyle() or clearStyle(). There is 
an effect, SetStyleAction, that allows you to accomplish the setStyle().

Is there some way of accomplishing clearStyle() as an effect? Using a 
SetStyleAction with a value of null does not work, as the style is 
still there, and for ints a null style value is often interpreted as 0.

At this stage I am thinking of making a custom effect, which seems easy 
enough, but did not want to re-invent the wheel.

RE: [flexcoders] Flex & CSS

[Gordon Smith]

I believe that a CSS selector such as #padre that starts with a # is
supposed to apply only to a tag with id="padre". Unfortunately, Flex
doesn't support this usage and therefore rejects the # syntax. The
closest thing would be to write a selector such as .padre that starts
with a dot and then put styleName="padre" on the tag(s) that you want it
to apply to.

RE: [flexcoders] Re: Helpers - Global function

[Gordon Smith]

It's possible to declare package-level functions. For example:
 
MyApp.mxml
--
 

http://www.adobe.com/2006/mxml
 ">
 



 

 

 
doSomething.as
--
 
package
{
 
public function doSomething():void
{
trace("doSomething");
}
 
}

However, you can declare only one such public function per file so this
isn't typically done.
 
My advice is to re-orient yourself as to what constitutes a "normal
helper". Since Flex is strongly class-oriented, the best practice for
creating helper functions in Flex is to make them static methods of
helper classes. This is what we do in the mx.utils package of the
framework.

RE: [flexcoders] Dynamically Changing Easing Function Again

[Jason Szeto]

Amy,

 

Did you import the easing functions? (ie. import mx.effects.easing.*). I
think you'll also have to create dummy variables of each class. These
classes won't be linked into the swf unless you perform these steps.

Subject: [flexcoders] Dynamically Changing Easing Function Again

 

I am trying to create an easing function explorer to be able to compare

syntax to change out the function at runtime. I feel like I am really 
close here, but I am at a loss as to what else to try. Here is the 
function I am using.

private function onListChange(e:Event):void {
easingFunction = e.target.selectedItem.label;

[flexcoders] player update followed by redirect loses URL variables

[dr_stone_1024]

I have run across some problems where a user using IE6 on WinXP will
access my flex app and be forced to upgrade to Flash Player 9.  This of
course is expected behavior, but the adobe.com does not redirect the
browser back to my app correctly.  What is happening is:

1) A user clicks a link such as
http://www.mydomain.com/flex/myapp.cfm?i=1&j=2


2) The myapp.cfm includes an embeded SWF (my flex app) that requires the
flash 9 update, so the user is prompted to update which takes them to
adobe.com temporarily.

3) Once the update is complete the user's browser is redirected back to
http://www.mydomain.com/flex/myapp.cfm
 .  Now without the variables I
need.

Has anyone seen this behavior?  This is happening a lot with our app - I
have been able to reproduce this problem using an unpatched XPSP2
install with IE6 (Flash 6 pre-installed).

Thanks,

Seth

I'm getting this error while trying to call play() on a glow effect
I've created. I'm trying to call play() from within a function that is
called as a result of a bindable value being changed. Basically I have
a data model with bindable data and a Label which displays the data.
When the data changes, I'm trying to play the glow effect on the label
to highlight the change. What am I doing wrong?

All these objects are defined in the same .mxml file. Relevant
snippets are : 


...
(inside script tag)
public function getQtyDisplay(currentQty:int, maxQty:int):String {
var result:String = currentQty+"("+maxQty+")";
qtyGlow.play();
}
...

...


The getQtyDisplay() function works fine w/out the play() call. After I
added it I started getting this error, so I wrapped the play() call in
a try/catch block.

[flexcoders] Re: Access Flash through JS - FABridge?

[bloodylag]

hmm I'm not sure I understand what part is your problem.

Are you having problem making javascript calls to flex using FABridge?

You seem to have set up the fab call right in flex. Now in your
javascript you should do some of the following.

When you insert your flash file into the html, you have to set up a
bridge name via the flashvars. For example



Now that you've done that you can set up some javascript calls to
ensure the flex has loaded fine.



var flLoaded = false;
var flexApp;

var initCallback = function() {
flexApp = FABridge.flex.root();
if(flexApp){
flLoaded = true;
}
return;
}

// register the callback to our Flex application with the 'bridgeName'
of 'flex'

FABridge.addInitializationCallback("flex", initCallback);



That will set up the connection to the flex application, to make calls
to flex functions simply do

if(flLoaded){
   flexApp.flexFunctionName();
}


Now to make calls from flex to javascript I normally use the External
interface call.

ExternalInterface.call("javascriptFunction", parameter);

I hope this helps

As the other answer told you, there is no waiting, threading, or the
likes. Flex is totally asynchronous in its operations. If you are
currently "waiting" by not executing more until the event comes back,
that is one way.

I have covered this extensively with respect to remote methods calls on
my blog, but the problem is basically the same. You might get some
valueable information by reading these entries about using events,
designing with callbacks and designing with tokens:

Waiting using a modal dialog

[flexcoders] Re: Flex 3 + LiveCycle: Is debugging Java possible?

[Uber_Nick]

You should be able to debug the Java code just fine.  If you're using
JBoss, make sure the debugging is enabled.  The run script has a line
in it like this:

#JPDA options. Uncomment and modify as appropriate to enable remote
debugging .

#JAVA_OPTS="-classic -Xdebug -Xnoagent -Djava.compiler=NONE
-Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n $JAVA_OPTS"

Make sure its uncommented.  Once JBoss is running, you can choose
remote debugging in Eclipse.  The standalone FlexBuilder doesn't
include this, so you can add it as a plugin, or just download a second
version of Eclipse and run both at the same time.

In Eclipse, go to Open Debug Dialog -> new Remote Java Application ->
(select project) -> Host: localhost -> Port: 8787 -> Debug

Subject: [flexcoders] Showing icons in ComboBox dropdowns


  
  I need to show icons next to the items in a ComboBox dropdown. Unlike the 
List class, the ComboBox has no iconFunction property, and its default item 
renderer class, ListItemRender, has a *protected* icon property. 
   
  I tried accessing the ComboBox's dropdown property directly, but that didn't 
work out well. Since it seems to use a different ListBase instance each time 
its displayed, the dropdown's labelFunction property has to be set in a 
DropdownEvent.OPEN handler, and this event is fired *after* the dropdown is 
visible, so you intially see the dropdown without icons and then the icons 
appear.
   
  It seems that to accomplish this, I'll have to, at minimum, subclass 
ListItemRenderer. But this seems a rather cumbersome solution for what I 
suppose is a common need. Is there an easier way to do this?
  

  

 

[flexcoders] widget creation on Flex builder and related problems - need some help

[maritakous]

Hi all.
I am trying to create a desktop widget application and it seems I have
made a mistake. As you know, desktop widgets are like small stickers,
they do not appear on taskbar and can be hidden or docked.
The problem is that I created an AIR application using Flex Builder 3
Beta and now I cannot find how to make that application behave like
custom-shaped window. My app appears on Windows taskbar and I don't
want it. When I drag the window (which is a custom shape) it shows
that nasty dragging rectangle around it.
As far as I found out (and tried it) I need to use cod like:
var initOptions:NativeWindowInitOptions = new NativeWindowInitOptions();
initOptions.systemChrome = NativeWindowSystemChrome.NONE;
initOptions.type = NativeWindowType.UTILITY;

to hide my window from the taskbar. But it seems I cannot use such a
code for class mx:Application. Or can I (would be grateful for some idea)?
The main question is:
if I want to migrate my app to that NativeWindow based solution - then
NativeWindow is not an mx class and I cannot find how I will use Flex
Builder Design mode to arrange my GUI elements. Is it somehow possible
to wrap my mx:Application inside NativeWindow and do not have to
migrate the design from mxml files to pure ActionScript?

The second issue - if I want to use some kind of subforms - like
widget settings window - when I move that window with the mouse, it is
being clipped to the region of my Application. Does that again mean
that I need to use NativeWindow for creating such a "Widget settings"
dialog window?

Thanks for any ideas (and especially for useful links and examples :-) )

NavBar.as has this note:

I get an error that I am attemption to access an inaccessable

There is no threads or blocking.  After you put up the alert, don't
execute any more code until you get the event back from the Alert.

How would I implement a Confirm-like dialog in Flex? Basically, a

If scrollPolicy="auto" the scrollbar will overlap content.  If policy is

Yes, I had seen that, which is why I made sure I mentioned that I was 
trying to explore the built-in functions and not making a custom 
function.  I figured people would be less likely to send me to that ;-
).  However, if you see anything in what that is doing that would 
work for what I need, maybe I have missed something.  I would love it 
if I could find a way to use this as just a generic easing explorer 
for my own objects to see what the in-built easing functions do.

This is aggravatingly difficult to do...at this point it would have 
been far faster to just do a swich case and hard-code in all the 
easing functions.  Not very dynamic or extensible, though, which kind 
of goes against the spirit of Flex.

RE: [flexcoders] Re: Capture Flex screen to e-mail...

[Mike Krotscheck]

Search the docs :). Looks like IBitmapDrawable is implemented by
BitmapData and by DisplayObject.  Since Application extends
DisplayObject (well, eventually) it looks like you can do the following:

 

var bmp :BitmapData = new BitmapData(Application.application.width,
Application.application.height, false);

bmp.draw(Application.application);

 

Just don't be surprised if your memory usage spikes and you get .OCX
errors on machines with little memory.

[flexcoders] Showing icons in ComboBox dropdowns

[Dave Glasser]

I need to show icons next to the items in a ComboBox dropdown. Unlike the List 
class, the ComboBox has no iconFunction property, and its default item renderer 
class, ListItemRender, has a *protected* icon property. 
   
  I tried accessing the ComboBox's dropdown property directly, but that didn't 
work out well. Since it seems to use a different ListBase instance each time 
its displayed, the dropdown's labelFunction property has to be set in a 
DropdownEvent.OPEN handler, and this event is fired *after* the dropdown is 
visible, so you intially see the dropdown without icons and then the icons 
appear.
   
  It seems that to accomplish this, I'll have to, at minimum, subclass 
ListItemRenderer. But this seems a rather cumbersome solution for what I 
suppose is a common need. Is there an easier way to do this?

Thanks for the response, Dan.  That makes a lot of sense, but it would
be great if the AS3doc for "clipContent" went into that detail.  I'll
check the bug database to see if it's already been logged and if not,
log it as a docs enhancement.

For anyone else who may run into this problem, I was able to use a
workaround following an approach something like this example:


  private function handleResize(event:ResizeEvent):void
  {
drawingLayerMask.graphics.clear();
drawingLayerMask.graphics.drawRect(0, 0, workspace.width, workspace.height);
  }

Re: [flexcoders] UIComponent.graphics not respecting a grandparent's clipContent

This is by design.  Flex clipping is expensive (at least relative to not
clipping), so Flex Containers don't clip unless measurement says they
should.  Drawing isn't included in measurement.  You can use
mx_internal::forceClipping but then you're using mx_internal.

[flexcoders] VerticalScrollBar Not Being Accounted For?

[Matt]

Hey guys, I'm seeing an issue in my Flex code that I can't imagine has
gone unseen to this point. If I have a Box with vertical scroll policy
set to auto, the height is set to an explicit value, the width is set
to auto, and I've added several labels in a vertical layout that
causes the vertical scrollbar to appear it overlaps onto the label
text rather than allocating extra space necessary for the scrollbar. 
Is there an easy work-around for this or am I doing something wrong here?

Granted this will only happen for items that extend to maximum width
of the container and thus get overlapped by the space necessary to
display the vertical scrollbar, but this is problematic as I don't
want it to hide any of the text.

Thanks in advance!

[flexcoders] UIComponent.graphics not respecting a grandparent's clipContent

[Erik Price]

Hi,

I'm observing some strange behavior regarding the clipContent of a
Canvas as applied to some lines that are programatically drawn via one
of its grandchildren's Sprite.graphics object.  What I am seeing is
that the clipContent property is not respected by its grandchildren
(kids these days have no respect) if the intermediate child is not
outside of the Canvas's boundaries.

A diagram might help me explain this better:


  


If I programatically add children to "drawingLayer", and then use
those children's "graphics" property to draw lines programatically,
the lines will appear outside of "workspace".

What is interesting is that if I change the width and height of
"drawingLayer" to 201 (so that a part of "drawingLayer" appears
outside the boundaries of "workspace"), then the
"workspace.clipContent" is respected and the lines are clipped as
expected.  Unfortunately, I cannot use this as a workaround because
"workspace" needs its scroll policies set to "auto" for other reasons,
and having "drawingLayer" outside of "workspace" would cause
undesirable scroll bars.

Am I describing a known bug?  (Btw I can post a 20-line sample
application that demonstrates this.)

[flexcoders] Re: Application container failed to capture KeyboardEvent

[zhongtie]

Thanks Alex. That works!

When I switch to another application and then switch back, my all
flash application loses the focus and no event fires at all unless I
click somewhere in it. Is there any way around it?

You would set navItemFactory to a class factory for your button.

[flexcoders] SetStyleAction - clear style?

[rkettrey]

With respect to styles, you can setStyle() or clearStyle().  There is 
an effect, SetStyleAction, that allows you to accomplish the setStyle().

Is there some way of accomplishing clearStyle() as an effect?  Using a 
SetStyleAction with a value of null does not work, as the style is 
still there, and for ints a null style value is often interpreted as 0.

At this stage I am thinking of making a custom effect, which seems easy 
enough, but did not want to re-invent the wheel.

[flexcoders] Plot Using XML Attributes

[rketcham]

I have an xml file that I get through an http serivce:



I then use onResultHttpService to load the xml file into an XML list
collection

private function onResultHttpService( avResultEvent :ResultEvent ):void
{
   lvXmlList= (avResultEvent.result as XML).point;
   mvXmlListCollection = new XMLListCollection(
lvXmlList ); 
}

The XML file is as follows:



8190
8190



8190
8190



8190
8190



I want to be able to plot the channels with respect to the tick attribute in
the point node.  So, if I were to be using a line series, the first point
for channel 1 is (7981, 8190)  and  (7981,8190) for channel 2 - since they
both have the same value.


I want to plot this data using a line series:

 








Here's the problem: I can get the xaxis values to be defined as the value of
the tick attribute in the point node. I, however, am unable to plot the
channel amplitude with respect to the tick.  What do I need to type for the
yField value in order to access a specific channel (such as
lvXmlList.channel.(@number=="1"))?

Thanks.

Re: [flexcoders] Skinning a Panel in Flex

[Derrick Anderson]

i have had this same issue, and it's when i use bitmap graphics in flash
with scale-9, apparently it doesn't work that way, only on vector graphics
in flash.  what i do is reference the graphic file directly in css, and also
specify your scale9 grid in css as well.  then it should work.  or the
easier option is to convert your stuff to vector graphics, but i'm not a
graphics guy and have never had much luck with that.

I'm trying to skin panels for use in Flex, but my corners, which are
rounded, keep getting squished. I'm sure I'm doing it right in Flash: My
own drawing is lined up with the reference point (0, 0), the 4
guidelines for scale9 are in the right places and everything. And in my

Panel

  borderThicknessLeft: 16;

Where am I going wrong? Something else I should add, my panel gets
stretched depending on what size I want to make it at, but it looks like
the scale9 stuff is ignored completely, stretching the underlying swf as
if it were just one bitmap with no scale9 stuff.

RE: [flexcoders] Capture Flex screen to e-mail...

[Mike Krotscheck]

The graphic nature of Flex makes it so your only real option is to
screenshot the application and mail it to them as a graphic. To do this
within Flex, see whether Application implements IBitmapDrawable- that
will allow you to use bitmapData.draw() and get the raw display data.
Once you have that, you've got two options: If you're in an AIR
application, you can just write the file to the desktop and have them
mail it. If not, you'll need to bounce it out to a server and mail it
from there.

 

Make sure you call BitmapData.dispose() though- they're normally passed
over by garbage collection.

Subject: [flexcoders] Capture Flex screen to e-mail...

 

In an application that I wrote years ago in ASP classic, I had a 
button on every page that would allow the user to e-mail the current 
page to someone. It would actually capture the innerHTML, and append 
it to an e-mail and send it. The purpose was to capture a snapshot of 
the data at the time the page was rendered. It was great for trouble 
shooting customer complaints because we could see what they saw at 
that particular time (thit was a 600 user DB app, and the data 
changed frequently).

I would like to do something similar in Flex. Yes I know I can have 
the user do an Alt-Print-Screen, and paste it into word or paint, and 
send the image, but I was hoping for something more seamless. 
Something I coud put on each panel that the user could click, and it 
would popup a box that would ask where to e-mail it to. It would 
attach the current rendered panel to an e-mail as a jpg, pdf, png... 

I have the e-mail piece operational, but I haven't a clue where to 
start on the capture piece.

Anybody have any good ideas?

[flexcoders] Access Flash through JS - FABridge?

[s_tibrewal]

Hello Folks,

I have a Flash project with corresponding .fla and .swf files. I am
trying to manipulate the flash through JavaScript. I could manipulate
flex .swf files rather easily through the FABridge but I am not quite
sure how to use the FABridge in the Flash context.

The problem arises because in the .mxml files for Flex, I simply
insert  and all that I can do in
Flex can be done in JS. This code insertion is done in the XML part of
.mxml file, outside the  tag. Since Flash is all
ActionScript, how do I make the functionality from the .swf file
created through Flash available to JavaScript?

I have heard of tools like AFlax but I am hoping that instead of
having to learn another interface, somehow I could just use FABridge
with Flash.

Would appreciate any thoughts anyone has - sounds like a fairly common
issue for someone trying to manipulate Flash and there must be an easy
solution for this out there. I am fairly new to Flex/Flash so if I am
mixing some terminology please let me know and I will be happy to clarify.

Thanks,
Sanjay.

[flexcoders] Re: HttpService not called the first time

[gers32]

Being a Flex newbie, I can only think of one way to solve this dilemma
(assuming I ever encounter performance problems at startup):

I thought it was a good idea to implement each HttpService in the
Component that displays the retrieved data, which is saved to an
application-wide Model, accessible to all Components. One solution
would be to centralize all HttpServices in the main application file;
they would populate the Model in the same way, but not require the
existence of their corresponding Components.

I'm sure there are better solutions out there... Thanks,

Chris.

Hello All!!!

I am creating a bubble chart with custom renderer. The render item

a button in a canvas. Depending on the bubbles' value the buttons
get their color.
This part works fine.

I have another custom itemRenderer which I want to assign to the
bubbleSeries

The problem I am having is -- assigning itemrenderer dynamically to
a bubbleserier.

Here are the lines that I tried but did not work:

// bubblechart is main charts id
series.itemRenderer = new ClassFactory(bubbleRenderer1); //
bubbleRenderer1 is custom renderer

Any help will be appreciated.

[flexcoders] adding children: best practices

[johantrax]

Hi all,

I have some components that dynamically generate their children.
However I'm wondering what would be the best practice for this, or
which method you prefer and why.

Currently I'm down to 2 methods:
1. creating/adding the childcomponents in an initialize handler,
bindings get executed in a creationCompleteHandler except when they
influence the layout (like the width/height of a datagrid)

2. overriding the createChildren-method, again most binding go into
the creationCompleteHandler()

Appreciate every opinion,

[flexcoders] Data Binding and dealing with NULLs

I hit this problem quite often and wonder if there is a general
solution...

I have a component which displays a list of questions and has the
concept of a "current" question i.e. the question the user is answering:





The problem is that the questions array doesn't get populated until
after Flex has tried to setup all the bindings meaning I get a
NullPointer when it tries to setup "currentQuestion".

At the moment I have to get around this with the following code:






This seems quite hacky...

Re: [flexcoders] Re: Flex Remoting Options - Any Opinions?

[Douglas McCarroll]

I'd like to repeat Steven's question. I'm really curious about this.
How many simultaneous connections can LCDS handle on one CPU? I
realize that this will vary a great deal, depending on the application
and the CPU, but it would be great to get a ballpark idea.

Anatole - you suggested, "I would try to see if you can scale
application in any other way - 4 core single CPU and removal all
business functionality to different servers".  Have you done this or
something similar on some of your projects? If so, how many
simultaneous users will these apps support?

And does anyone else have any experience with this?

This is obviously an important question. Going beyond one CPU takes us
from "free" to "lots of money". What will "free" handle? I've been
curious about this for quite a while and have yet to run across any
information on the subject.

Thanks in advance for any input!

Re: [flexcoders] Index of item in list

[Muzak]

Make sure your item renderer implements IDropInListItemRenderer
Define a listData getter/setter, which, when set by the component using the 
item renderer, will contain the index you need.

http://livedocs.adobe.com/flex/201/langref/mx/controls/listClasses/IDropInListItemRenderer.html
http://livedocs.adobe.com/flex/201/langref/mx/controls/listClasses/BaseListData.html

If you're writing the item renderer in MXML and the base class does not 
implement IDropInListItemRenderer, you can do the following:


http://www.adobe.com/2006/mxml";
 implements="mx.controls.listClasses.IDropInListItemRenderer"
