Re: [flexcoders] Index of item in list
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:
?xml version=1.0 encoding=utf-8?
mx:Canvas xmlns:mx=http://www.adobe.com/2006/mxml;
implements=mx.controls.listClasses.IDropInListItemRenderer
mx:Script
![CDATA[
import mx.controls.listClasses.BaseListData;
// Internal variable for the listData property value.
private var _listData:BaseListData;
[Bindable(dataChange)]
public function get listData():BaseListData {
return _listData;
}
public function set listData(value:BaseListData):void {
_listData = value;
}
/mx:Canvas
You can then use _listData.columnIndex, _listData.rowIndex
And, if you haven't already, read Alex's article about DataGrid/List item
renderers:

I am using a list control and trying to give a alternate styles to it.
(not just alternate colors).
Hence I want to know the index at which the current Item is going..
Is there any way to know the instance of item renderer it's

Something like this :
mx:List itemRenderer = myItem dataProvider ={p}/
comp myItem :

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

For high-end applications we extend LCDS stack to fix underlying TCP/IP problems( financial clients, real-time messaging). We do not advertise low end product as it potentially might have reliability problems. Indeed, in order to provide even basic recoverability and batching on the top of openAmf we had to write tons of code. Only with significant investment and know how you can get comparable performance and reliability Unless Adobe releases both ends of the protocol in the open source you would have inherient reliability issues. While we acquired significan know how in the last 2 years, using native AMF and RTMP classes is a risky business as Adobe constantly changes framework and pieces of protocol. The main effort of the testing should be around protocol performance and reliability ( like pulling the network wire).and it can be a while till AMF/RTMP will become standard - most likely only after release of the client/server code in open source.

[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:
mx:Script
![CDATA[
import mx.collections.ArrayCollection;
[Bindable]
public var questions:ArrayCollection;
[Bindable]
public var currentQuestion:MultipleChoiceQuestion =
questions[lstBox.selectedIndex];
]]
/mx:Script
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:
!-- Databinding of Current Question --
mx:Script
![CDATA[
private function init():void {
refreshCurrentQuestion();
}
public function refreshCurrentQuestion():void {
if (questions != null) {
currentQuestion =
questions[lst.selectedIndex];
}
}
]]
/mx:Script
This seems quite hacky...
[flexcoders] adding children: best practices
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, --jeetee

[flexcoders] Re: HttpService not called the first time
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. --- In flexcoders@yahoogroups.com, Tracy Spratt [EMAIL PROTECTED] wrote: Defeat deferred instantiation judiciously, if at all.

[flexcoders] Access Flash through JS - FABridge?
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 fab:FABridge xmlns:fab=bridge.*/ 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 mx:Script 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.
RE: [flexcoders] Capture Flex screen to e-mail...
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.

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.

[flexcoders] Plot Using XML Attributes
I have an xml file that I get through an http serivce:
mx:HTTPService id=nodeChannels url={url}
result=onResultHttpService(event) resultFormat=e4x/
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:
data
point tick=7981 timestamp=0-0-0T00:00:00.0
channel number=18190/channel
channel number=28190/channel
/point
point tick=7982 timestamp=0-0-0T00:00:00.0
channel number=18190/channel
channel number=28190/channel
/point
point tick=7983 timestamp=0-0-0T00:00:00.0
channel number=18190/channel
channel number=28190/channel
/point
/data
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:
!-- Begin Graphing --
mx:LineChart id=DataChart width=100% height=95% alpha=1.0
mx:series
mx:LineSeries id=c1 displayName=Channel 1
dataProvider={mvXmlListCollection} yField= xField=@tick/
mx:LineSeries id=c2 displayName=Channel 2
dataProvider={mvXmlListCollection} yField= xField=@tick/
/mx:series
/mx:LineChart
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.

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?

[flexcoders] UIComponent.graphics not respecting a grandparent's clipContent
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: Canvas id=workspace width=200 height=200 clipContent=true UIComponent id=drawingLayer width=200 height=200/ /Canvas 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.) Thanks in advance! Erik

[flexcoders] VerticalScrollBar Not Being Accounted For?
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!
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.

This is by design. Flex clipping is expensive (at least relative to not

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:
Script
private function handleResize(event:ResizeEvent):void
{
drawingLayerMask.graphics.clear();
drawingLayerMask.graphics.drawRect(0, 0, workspace.width, workspace.height);
}
/Script
Canvas id=workspace resize=handleResize(event)

[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?

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

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

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 :
myNS:Order id=order
...
(inside script tag)
public function getQtyDisplay(currentQty:int, maxQty:int):String {
var result:String = currentQty+(+maxQty+);
qtyGlow.play();
}
...
mx:Glow id=qtyGlow target=qtyDisplay color=0x99FF66/
...
mx:Label id=qtyDisplay text={getQtyDisplay(order.currentQty,
order.maxQty)}/
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] widget creation on Flex builder and related problems - need some help
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 :-) )

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.

[flexcoders] Re: Access Flash through JS - FABridge?
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
PARAM NAME=FlashVars VALUE=bridgeName=flex
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

Subject: [flexcoders] error 1006: value not a function; on effect.play()
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 :
myNS:Order id=order
...
(inside script tag)
public function getQtyDisplay(currentQty:int, maxQty:int):String {
var result:String = currentQty+(+maxQty+);
qtyGlow.play();
}
...
mx:Glow id=qtyGlow target=qtyDisplay color=0x99FF66/
...
mx:Label id=qtyDisplay text={getQtyDisplay(order.currentQty,
order.maxQty)}/
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] player update followed by redirect loses URL variables
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=1j=2 http://www.mydomain.com/flex/myapp.cfm?i=1j=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 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
RE: [flexcoders] Dynamically Changing Easing Function Again
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.
GetDefinitionByName will only return a result if the class is linked in.

RE: [flexcoders] Re: Helpers - Global function
It's possible to declare package-level functions. For example:
MyApp.mxml
--
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml
http://www.adobe.com/2006/mxml
mx:Script
![CDATA[
private function clickHandler():void
{
doSomething();
}
]]
/mx:Script
mx:Button click=clickHandler()/
/mx:Application
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] Flex CSS
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.

the scale9 stuff is ignored completely, stretching the underlying swf as

You don't say what's going wrong, but I suspect that

in your SWF... the MXML compiler has no way of knowing that your app

to declare a static var of that type. Note that simply importing it is

[flexcoders] Re: player update followed by redirect loses URL variables
Hey Seth, I know this isn't a solution your looking for but is it possible for you to store those values into a session variable to use again later if the i and j aren't set in the url. Again I have nothing further to suggest with the main argument you described sorry.
[flexcoders] Re: Dynamically Changing Easing Function Again
--- In flexcoders@yahoogroups.com, Gordon Smith [EMAIL PROTECTED] wrote: This is aggravatingly difficult to do. 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. 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? -Amy
[flexcoders] tweening an iframe container
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!
Eric

// I have made some additions to the original code
//
// - javascript support functions are now generated by the component and
// inserted directly into the DOM.
//
// - Component generates it's own div and iframe element and inserts them
// into the DOM.
//
// - When the component is created the display list is traversed from the
// component down to the root element. At each traversal a test is made to
// see if current component is a container. If it is a container then the
// child of the element which leads back to the component is determined and
// a note madeof the appropriate 'index' on the path. The index is stored
// against a reference to the Container in a Dictionary. Also the container
// is 'seeded' with an event handler so that if the container triggers an
// IndexChangedEvent.CHANGE (i.e. when you click on a tab in a viewstack)
// the path of 'index' values down to the component
[flexcoders] How can I avoid jumping / flickering when changing the dataprovider in a list box?
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 Anz http://www.flickrmailer.com http://www.flickrmailer.com/
