Re: [flexcoders] Re: Getting Its Function Name...
If you want to call the current function recursively, you can use
arguments.callee
function something( count : int )
{
trace( count );
if( count 0 ) arguments.callee( count-- );
}
Cheers
Ralf.

[flexcoders] How to set variableRowHeight = true in MenuBar
I want make the same effect as following url:
http://blog.flexexamples.com/2008/10/02/adding-a-horizontal-separator-
to-a-flex-popupbutton-controls-pop-up-menu-redux/
I haved tried 2 methods to solve the problem,
//method 1
private function onMenuBarInitialize():void {
var menu:Menu;
for (var i:int = 0; i menuBar.menus.length; i++) {
menu = menuBar.menus[i];
menu.variableRowHeight = true;
}
}
//method 2
private function onMenuShow(event:MenuEvent):void {
var t:MenuBar = event.currentTarget as MenuBar;
event.menu.variableRowHeight = true;
}
mx:MenuBar id=menuBar width=100% labelField=@label
initialize=onMenuBarInitialize iconField=@icon styleName=menuBar
itemClick=onMenuBar(event) menuShow=//onMenuShow(event)
mx:XMLList
menuitem label=File
menuitem label=New icon=documentIcon /
menuitem label=Open...
icon=documentIcon/
menuitem type=separator /
menuitem label=Close /
menuitem type=separator /
menuitem label=Save /
menuitem label=Save as... /
menuitem type=separator /
menuitem label=Import... /
menuitem label=Export... /
menuitem type=separator /
menuitem label=Exit /
/menuitem
menuitem label=Edit
menuitem label=Cut /
menuitem label=Copy /
menuitem label=Paste /
menuitem type=separator /
menuitem label=Select All /
menuitem type=separator /
menuitem label=Find /
/menuitem
/mx:XMLList
/mx:MenuBar
But, child menu of MenuBar still presents some space at feet when it
shown(click on MenuBar) for the FIRST time, and It presents normally when it
shown for the second time.
Maybe it's a BUG of FLEX?!
Re: [flexcoders] Detect a databinding
Hi Marco, first up you have to ask yourself why you want this feature? There may be another way to solve the problem. However, here's what I know of your specific question... Last time I checked (Flex 3 beta 2) there was no *official* way to inspect the bindings on a component at runtime. However, if you create a component with bindings and load it up at runtime, you will find there are undocumented properties that enable you to do this. Look for a _watchers array -- you will also find it helpful to keep the generated actionscript that the Flex compiler normally throws away so you can read how databinding is implemented. The properties above are not part of the public API, so could change at any time. In fact, IIRC some of the very binding properties I just mentioned may even have been deprecated in the final Flex 3 release... proceed with caution. Which is why I ask what the actual problem is you are trying to solve -- perhaps the list can help you come up with other ideas :-) For example, your idea of overriding addEventListener is cunning -- perhaps that solution can be explored further. Cheers, Jules On Tue, Dec 2, 2008 at 23:05, Marco Catunda [EMAIL PROTECTED] wrote: Hi, I have a singleton class with model data provider (like cairngorm model).

But it don't work because the removeEventListener isn't call when component go away. Does anyone has any tips? Regards -- Marco Catunda
RES: [flexcoders] Re: Game Architecture
Hi! In case of Remote Objects, thats correct, you'll need to query the server time to time to get the result of a turn. About the security of the RO's, its a open connection to your database for everyone, i.e, you have a method increaseXP(player, amount), if you dont apply the certain security for that, you'll get a lot of max level players in 2min. In your case, ild go for Consumer/Producer messaging, but, you need to create a lot of them for each lobby/room/game, discarding the unwanted messages on the server, not consuming bandwith. If you use just one consumer and switch every message on Client side you'll have a high use of unnecessary bandwith.

[flexcoders] Zoom effect absolute positioning
Hello, I have a canvas within my application that contains polaroid images (own flex component). When I click on a polaroid I wan't it to zoom all over my application. When I do this now it stays within the canvas and I get scrollbars (on that canvas). Is there a way to keep the pictures on the canvas and still be able to zoom over my whole application (When zooming - go to absolute layout)? Somebody that knows if this is possible ? Thanks, Ward

[flexcoders] Re: objects bound to datagrid not gc'd when dataprovider set to null
Could anyone point me in the right direction? I've removed - * data binding references * remote object call references - clearResult However, after setting the dataprovider for my grid to null - the grid shows no items, in the debugger the dataprovider has a length of 0 - there are still references to the objects. All of the references seem to be coming from datagriditemrenderers (I do not use any special item renderer, simply the default). The reference list/tree is large with and incomprehensible to me - but they all seem to be coming from classes I don't control. Any thoughts?

[flexcoders] ItemRenderer, mislabels scrolling
When scrolling, the labels on the grid turn into those that the
recycled item renderer used. I tried using this.data to overwrite
the values every time. The new listData object has the correct
label and so I thought it was working, but there is a url I need in
the current rows' XML for the button click to work and accessing the
this.data gave me the old results. I then thought I could use the
row index in listData but quickly found that the row index is always
the same when scrolling down or up, the end or the begining of the
grid. So it's not really the row index of the XML but the grid.
Seems overwritting the values wasn't quite the answer.
There is a variable in listData called item. I see it in the
debugger but the compiler won't let me access it. This is the XML
for the row. So, in short, how can I access this 'listData.item' or
find out the actual XML row I am on. Actually, any suggestion would
be great. Banging my head on this one all day.
And thanks.
Here's some code:
public function get listData():BaseListData{
return _listData;
}
public function set listData(blData:BaseListData):void{
_listData = DataGridListData(blData);
renderData();
}
private function renderData():void {
var columnIndex:int;
var xmlRow:XML;
columnIndex = this.listData.columnIndex;
xmlRow = XML(this.data);
/*
* I added this to get at the item.
try{
if(this.listData.item != null){
xmlRow = XML(this.listData.item);
}
else{
xmlRow = XML(this.data);
}
}
catch(e:Error){
xmlRow = XML(this.data);
}
*/
this.value = this.listData.label;
if ( value == [multiple] ){
this.creativeLinkButton.enabled = false;
this.creativeLinkButton.useHandCursor = false;
this.creativeLinkButton.setStyle(textDecoration, none);
}
else{
this.creativeLinkButton.enabled = true;
this.creativeLinkButton.useHandCursor = true;
this.creativeLinkButton.setStyle(textDecoration, underline);
}
// get toolTip = @u(columnIndex)
// get url = @u(columnIndex)
var urlName:String = @u + columnIndex.toString();
this.url = xmlRow[urlName];
this.description = xmlRow[urlName];
}
override protected function setMXMLViewBindings():void{
super.setMXMLViewBindings();
this.logger.debug(setMXMLViewBindings);
// Set creativeLink link button's label
BindingUtils.bindProperty(this.creativeLinkButton, label, this,
[value]);
// Set creativeLink link button's toolTip
BindingUtils.bindProperty(this.creativeLinkButton, toolTip,
this, [description]);

[flexcoders] getting what fired a change sliderEvent -- is it possible?
-- Forwarded message -- From: Matyas Forian Szabo [EMAIL PROTECTED] Date: 2008/12/2 Subject: getting what fired a change sliderEvent -- is it possible? To: flexcoders@yahoogroups.com Hi im in a making of a flex application that will display a zoomed in part of an image. Above the image is a scrollbar (a HSlider) which has 2 thumbs. If i drag the image, the scrollbar moves according to the x coordinate of the image im viewing. If i drag the thumbs on the scrollbar flex should display that part of the image which im setting with the slider tumbs. My problem is: If i drag the image i can alter the slider's thumb positions with setThumbValueAt(). Then i add a change event to the HSlider to be able to pan the image with the slider's thumbs. BUT this change event gets fired if im dragging the image too. (So it modifies the image position, altough i want to only modify the thumb position) So what i'd need (i guess) is a way to determine what fired the change event: the clicking/dragging of my slider object of the dragging of my image. Any ideas? thank in advance!

[flexcoders] application structure
Hi, I'm writing my first flex app. So far it all works, but I'm getting to the point where I need to start structuring it, for ease of further development. Right now I simply have many functions defined within the script tag within the application. I'm now thinking through my options for structuring this better. I'm not asking for *specific* structuring recomendations, as I know that would be imposisble w/o you knowing the specifics of what I'm doing. What I'm looking for is a good place to read about the different options, so I can learn about them. Preferable free online, or in Safari Books Online. To be clear: when I say structural options I mean things like: a) having all the code in the script b) putting the code in a seperate .as and point script source= at it (I know this is very similar to (a) ) c) using static methods in a 'static' class d) creating classes to fully OOize the code e) something else I dont yet know about... I'm reading 'Advanced Action Script 3 with Design Patterns', which I hope will help, but I would like to have some flex specific knowledge also, so that I can see examples of how to allow objects outside the application to access those defined by mxml within the application (like buttons). I'm concerned that will end up with a lot of Application.application.foo type code - is that 'normal'? I'm hoping this makes enough sense... thanks tom

does not release its reference to the data member. While digging into
the code, I've found out that Adobe has access to the list through the
mx_internal namespace. So, I cooked up a small helper function to
release the itemRenderer. Try to adapt it to the grid.
BEGIN CODE
import mx.core.mx_internal;
use namespace mx_internal;
/**
* Helper function that cleans up a list's item renderers.
*
* PThe item renderers contain a data member that holds a reference to
the data the list was
* trying to display. The list doesn't clean up the item renderers data
member when the list provider is set
* to null. So, this reference prevents elements from being garbage
collected and needs to be manually cleaned up/P.
*
* @param list The list for wich the Item Renderers need to be cleaned
up.
*
*/
public static function cleanItemRenderersData(list:ListBase):void {
var renderers:Array = list.rendererArray; // two dimensional array
var renderer:IDataRenderer = null;
for (var row:int = 0 ; row renderers.length ; row++) {
for (var col:int = 0 ; col renderers[row].length ; col ++) {
renderer = renderers[row][col] as IDataRenderer;
renderer.data = null;
}
}
}

Subject: [flexcoders] Re: objects bound to datagrid not gc'd when
dataprovider set to null
Could anyone point me in the right direction?
I've removed -
* data binding references
* remote object call references - clearResult
However, after setting the dataprovider for my grid to null - the grid
shows no items, in the debugger the dataprovider has a length of 0 -
there are still references to the objects.
All of the references seem to be coming from datagriditemrenderers (I
do not use any special item renderer, simply the default). The
reference list/tree is large with and incomprehensible to me - but
they all seem to be coming from classes I don't control.
Any thoughts?

Re: [flexcoders] application structure
Hi Tom, You've hit on one of the classic anti-patterns of Flex programming: Application.application.blah type stuff. While this is regrettably somewhat 'normal', that doesn't mean it's ok :) As you probably have guessed, it leads to code that is really hard to change later on as it is all tangled up with itself. The solution is to use one of the application patterns that have been studied by the GUI programming community in general (not just Flex programmers) ... such as MVC (Model-View-Controller). Martin Fowler is one of the canonical sources on this stuff: http://martinfowler.com/eaaDev/uiArchs.html Mate, Parsley or Cairngorm are open-source Flex frameworks that implement the shell of one or more GUI patterns to save us all re-inventing the wheel. Realistically, most people learn the patterns by using one of these frameworks or their cousins (there are more, I'm just giving a few that are currently flavour of the month). Cairngorm has been getting a bad rap lately due to testability of the resulting application (or lack thereof), but it's deeply embedded in the Flash community (for better or worse). Martin Fowler et al will give you an academic understanding, introduce you to some code (Martin Fowler uses C# WinForms), explain the finer points and describe several variations that you may or may not find interesting. You've bitten off quite a large topic with that innocuous question ;-) Jules On Tue, Dec 2, 2008 at 23:56, tom s [EMAIL PROTECTED] wrote: Hi, I'm writing my first flex app. So far it all works, but I'm getting to the point where I need to start structuring it, for ease of further development.

I'm not asking for *specific* structuring recomendations, as I know that would be imposisble w/o you knowing the specifics of what I'm doing. What I'm looking for is a good place to read about the different options, so I can learn about them. Preferable free online, or in Safari Books Online. To be clear: when I say structural options I mean things like: a) having all the code in the script b) putting the code in a seperate .as and point script source= at it (I know this is very similar to (a) ) c) using static methods in a 'static' class d) creating classes to fully OOize the code e) something else I dont yet know about... I'm reading 'Advanced Action Script 3 with Design Patterns', which I hope will help, but I would like to have some flex specific knowledge also, so that I can see examples of how to allow objects outside the application to access those defined by mxml within the application (like buttons). I'm concerned that will end up with a lot of Application.application.foo type code - is that 'normal'? I'm hoping this makes enough sense... thanks tom

[flexcoders] Detect a databinding
Hi, I have a singleton class with model data provider (like cairngorm model). Some user interface components binding this model in data provider property. I didn't find out any way to detect if there is binding in this model or not, and how many bindings. The binding model works with events, so my idea was override addEventListener in singleton model to detect binding. But it don't work because the removeEventListener isn't call when component go away. Does anyone has any tips? Regards -- Marco Catunda
RE: [flexcoders] Zoom effect absolute positioning
Hi Ward, I don't think that switching to an absolute layout would have the desired effect. For one thing, your thumbnails probably have no explicit location and are just being positioned by the Canvas layout manager, so if you switch to absolute, they might just decide to go put themselves at (0,0). You could turn off autoLayout for the duration of the effect, but that's usually a temporary thing done during and effect and not a long-term situation you want to be in. One solution might be for your Canvas to be wrapped in a custom component, subclassing UIComponent. When you click on a thumbnail, put a copy of the image into the wrapping container and zoom in on that. It will then cover everything below it. When you zoom back out, remove it from the wrapping component, and you'll see everything behind it again. Chet.

[flexcoders] Re: Flex nested tree get data from mysql and php
So I am trying to build a MPTT (nested tree) object in php, I have a
few questions for this group because I am not sure how the data should
be returned. I have been using static data and have a few questions
on what is contained within the data. Here is my arraycollection:
private var myDataProvider:ArrayCollection = new ArrayCollection([
Region:Southwest,ID:1,Territory_Rep:Tom Jones, children: [
{Region:Arizona,ID:2, children: [
{Territory_Rep:Barbara Jennings, ID:3},
{Territory_Rep:Dana Binn,ID:4}]},
{Region:Central California,ID:5, children: [
{Territory_Rep:Joe Smith, ID:6}]},
{Region:Nevada, ID:7, children: [
{Territory_Rep:Bethany Pittman,ID:8}]},
{Region:Northern California, ID:9, children: [
{Territory_Rep:Lauren Ipsum,ID:10},
{Territory_Rep:T.R. Smith,ID:11}]},
{Region:Southern California,ID:'12', children: [
{Territory_Rep:Alice Treu, ID:'13'},
{Territory_Rep:Jane Grove,ID:14}]}
]}
]);
I am in need of some guidance, so bear with me :). I think that this
is an object {Territory_Rep:Joe Smith, ID:6}, is this an array
with an object {Region:Central California,ID:5, children: [
{Territory_Rep:Joe Smith, ID:6}]} ?
Here is my problem, I am creating some php data returns to flex with
arrays, object, assoc arrays. I am not sure what a flex
arraycollection is so I am running some tests. Here are some tests
that I have done,
Example #1
PHP CODE
$o1-name = 'Tom';
$o1-status = 'Dad';
$o2-name = 'Wendy';
$o2-status = 'Daughter';
$b[] = $o2;
$o1-child = $b;
$arr[] = $o1;
return $arr;
Charles Proxy Sees This:
com.mptt.MPTT.GetTree
Parameters
Results
[0]
name
status
child
[0]
name
status
Example #2
$o1-name = 'Tom';
$o1-status = 'Dad';
$o2-name = 'Wendy';
$o2-status = 'Daughter';
$o1-child = $o2;
$arr[] = $o1;
return $arr;
com.mptt.MPTT.GetTree
Parameters
Results
[0]
name
status
child
name
status
Example #3
$o1-name = 'Tom';
$o1-status = 'Dad';
$o2-name = 'Wendy';
$o2-status = 'Daughter';
$o1-child = $o2;
return $o1;
com.mptt.MPTT.GetTree
Parameters
Results
name
status
child
name
status
So when I return the 3 examples int an arraycollection:
var ac:ArrayCollection = new ArrayCollection(result.result as Array);
and use that array collection as a dataprovider for a combobox
mx:ComboBox x=204 y=107 id=cmbox dataProvider={ac}
labelField=name/mx:ComboBox
Only example 1 and 2 return anything and that is only the first name,
none of the child names propagate the Combobox.
So my question with all of this, how (what format) should I return my
data from php to flex so I can add it (the data) to an arraycollection.
Thanks for all the help, this group rocks,

[flexcoders] Mouse off stage and ajax bridge
Is there a way to stop all mouse event listeners from the stage? Or will I need to do it the hard way and track down all mouse event listeners. My issue is that I have a Hslider that controls a component. When a user stops scrolling for a certain amount of time, pausing, I update the component. Updating also sends out some new information to the html page via the ajax bridge. This causes the html page to popup up js run loading popup. Well, when the loading js popup comes up flash somehow loses focus of the mouse and still thinks the mouse button is pressed so when flash gets focus again the slider follows the mouse around even if the mouse isn't on the slider anymore. I really don't want to have to rework this old project. Wasn't an issue with flash player 9. I guess Adobe made flash player to fast, thus my js file is getting notification immediately.

Is there a way to prevent your swf file from being cached? I would like to prevent this in production and when using the template files (in bin-debug and bin-release). When using these two html files my browser seems to cache the swf requiring me to do a couple of cntrl-r's and sometimes a clear cache in Firefoxs options. Anyone else have this issue?
RE: [flexcoders] Flash being cached
By adding on a unique string to the path to the .swf file, you can force a download of the new swf. I use SWFObject to make this easier rather than using the normal auto-generated wrapper files for embedding the swf.

RE: [flexcoders] Padding/spacing before the first line in a TextArea
Are you talking about the white pixels top and right of the selection rectangle? I think that's always 2 pixels. You might be able to alter the position of the TextArea's internal TextField to get rid of that.

RE: [flexcoders] ItemRenderer, mislabels scrolling
itemRenderer.data should always be the data for the row. It should never be
the old data unless you overrode the setter.

Subject: [flexcoders] ItemRenderer, mislabels scrolling
When scrolling, the labels on the grid turn into those that the
recycled item renderer used. I tried using this.data to overwrite
the values every time. The new listData object has the correct
label and so I thought it was working, but there is a url I need in
the current rows' XML for the button click to work and accessing the
this.data gave me the old results. I then thought I could use the
row index in listData but quickly found that the row index is always
the same when scrolling down or up, the end or the begining of the
grid. So it's not really the row index of the XML but the grid.
Seems overwritting the values wasn't quite the answer.
There is a variable in listData called item. I see it in the
debugger but the compiler won't let me access it. This is the XML
for the row. So, in short, how can I access this 'listData.item' or
find out the actual XML row I am on. Actually, any suggestion would
be great. Banging my head on this one all day.
And thanks.
Here's some code:
public function get listData():BaseListData{
return _listData;
}
public function set listData(blData:BaseListData):void{
_listData = DataGridListData(blData);
renderData();
}
private function renderData():void {
var columnIndex:int;
var xmlRow:XML;
columnIndex = this.listData.columnIndex;
xmlRow = XML(this.data);
/*
* I added this to get at the item.
try{
if(this.listData.item != null){
xmlRow = XML(this.listData.item);
}
else{
xmlRow = XML(this.data);
}
}
catch(e:Error){
xmlRow = XML(this.data);
}
*/
this.value = this.listData.label;
if ( value == [multiple] ){
this.creativeLinkButton.enabled = false;
this.creativeLinkButton.useHandCursor = false;
this.creativeLinkButton.setStyle(textDecoration, none);
}
else{
this.creativeLinkButton.enabled = true;
this.creativeLinkButton.useHandCursor = true;
this.creativeLinkButton.setStyle(textDecoration, underline);
}
// get toolTip = @u(columnIndex)
// get url = @u(columnIndex)
var urlName:String = @u + columnIndex.toString();
this.url = xmlRow[urlName];
this.description = xmlRow[urlName];
}
override protected function setMXMLViewBindings():void{
super.setMXMLViewBindings();
this.logger.debug(setMXMLViewBindings);
// Set creativeLink link button's label

RE: [flexcoders] Mouse off stage and ajax bridge
Fake a MOUSE_UP event From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of flexaustin Sent: Tuesday, December 02, 2008 7:51 AM To: flexcoders@yahoogroups.com Subject: [flexcoders] Mouse off stage and ajax bridge Is there a way to stop all mouse event listeners from the stage? Or will I need to do it the hard way and track down all mouse event listeners. My issue is that I have a Hslider that controls a component. When a user stops scrolling for a certain amount of time, pausing, I update the component. Updating also sends out some new information to the html page via the ajax bridge. This causes the html page to popup up js run loading popup. Well, when the loading js popup comes up flash somehow loses focus of the mouse and still thinks the mouse button is pressed so when flash gets focus again the slider follows the mouse around even if the mouse isn't on the slider anymore. I really don't want to have to rework this old project. Wasn't an issue with flash player 9. I guess Adobe made flash player to fast, thus my js file is getting notification immediately.

[flexcoders] Re: Flex 3 - Export to Microsoft Excel?
I've successfully implemented two different approaches. The first approach just puts the data for Excel _on the clipboard_. It also uses Microsoft's uber-funky XML schemas to control the formatting of the resulting spread-sheet. This approach works nicely for both FF and IE, in my experience (and, in theory, it should work in any browser that supports the Flash VM, including clipboard access). The second approach uses the ExternalInterface API to call a JS function which uses ActiveX to invoke the Excel COM object. If the JS function is able to load the Excel object, it then calls the object's COM interface directly (via JS functions) in order to create a Workbook and then to load data into its cells. Unfortunately, this approach only works with IE, but it is slick if you can use it. But, having the first approach as a fall-back is a good idea even then, in my opinion. Let me know if you have any specific questions about implementing either of these. Regards, Jim

$this-Link = ;
$this-ParentMenuID = null;
}
}

package myServices
{
[RemoteClass(alias=Classes.Menu)]

public class Menu
{
//instance variables
private var _ID:String;

I parse the records from a MySQL database and create arrays as required.
I then populate the children property with the array of menuItem objects
of the submenu.

[flexcoders] Re: ItemRenderer, mislabels scrolling
I've had similar issues.
One of the things I've found is that it is important to reduce the
steps between this.data, or this.listData, and the property you're
populating.
If you can rewrite so that you bind directly on this.listData.label,
rather than set the value of 'value' and bind on 'value', I think
you'll probably be okay.
Alex - if you wrote a book on item renderers, I would buy it. Just so
you know there's a market.

When scrolling, the labels on the grid turn into those that the
recycled item renderer used. I tried using this.data to overwrite
the values every time. The new listData object has the correct
label and so I thought it was working, but there is a url I need in
the current rows' XML for the button click to work and accessing the
this.data gave me the old results. I then thought I could use the
row index in listData but quickly found that the row index is always
the same when scrolling down or up, the end or the begining of the

Seems overwritting the values wasn't quite the answer.
There is a variable in listData called item. I see it in the

[flexcoders] Replacement Date class?
Now that the whole ECMAScript thing has blown over, Adobe is free of being
quite so bound to it as a standard. They've expressed interest in doing
some things that they previously shied away from because of divergence from
the standard.
Is anyone else really interested in ditching the Date class? That thing
drives me nuts. The number one problem is that it's an object. So you get
something like this:
var myDate:Date = new Date(2008, 1, 1);
var myDate2:Date = myDate;
...
myDate2.month++;
It's an easy mistake to miss, especially for beginners, and it can be very
annoying to track done. It's also a pain that you can assign values to the
time, day, month, etc. properties and it screws up data bindings and
setters/getters. For example, if I have:
private var myDate:Date;
[Bindable] public function set myDate(value:Date):void
{
_myDate = value;
invalidateDisplayList();
}
public function get myDate():Date
{
return _myDate;
}
It works great until you do something like:
myDate.time = newDate.time;
or
myDate.date++;
Simliar difficulties exist when using a date dropdown control.
So is it time to get a new Date class? Perhaps a new one called DateTime
and make the old one deprecated.
What I'd love is for it to be a new primitive type (like Number, int,
Boolean) that would be stored the same way as the time property of Date and
would be manipulated through static functions of the DateTime class.
Examples:
var myDate:DateTime = DateTime.now();
trace(myDate:, myDate);
myDate: 1228248636245
myDate = DateTime.incHour(myDate);
myDate = DateTime.incMinute(myDate, 20);
myDate = DateTime.incMonth(myDate, -3);
myDate = DateTime.incHourUTC(myDate);
myDate = DateTime.encode(2008, 1, 1);
var hours:Number = DateTime.getHours(myDate2 - myDate1);
No more date or fullYear - use the much more intuitive day and
year. I would also like month to be one-based, but that'd probably make
enough people grumble that I'd be willing to live without it.
I dream of seeing all the existing controls and such that use Date updated
to use this code instead. I would have already created the DateTime class
if it wasn't for how much trouble daylight savings time, leap year and
internationalization would be.

Or will I need to do it the hard way and track down all mouse event listeners. My issue is that I have a Hslider that controls a component. When a user stops scrolling for a certain amount of time, pausing, I update the component. Updating also sends out some new information to the html page via the ajax bridge. This causes the html page to popup up js run loading popup. Well, when the loading js popup comes up flash somehow loses focus of the mouse and still thinks the mouse button is pressed so when flash gets focus again the slider follows the mouse around even if the mouse isn't on the slider anymore. I really don't want to have to rework this old project. Wasn't an issue with flash player 9. I guess Adobe made flash player to fast, thus my js file is getting notification immediately.
Re: [flexcoders] Replacement Date class?
It'd be great to have some date math methods in there as well. Simple
things like getting the # of days/weeks/months between 2 dates is
currently much more clunky than it ought to be. It'd be nice if it had
some of what perl's DateTime module is capable of.

Re: [flexcoders] Re: Flex 3 - Export to Microsoft Excel?
A third option posts HTML Table formatted data (in a new browser window) to a server-side script (ColdFusion in my case but ASP/JSP/PHP should work as well) which then reflects it to the browser with the MIME type set to one of the myriad Excel versions. Then the browser handles it as needed (save file, ask user, open in Excel, etc.).

This approach works nicely for both FF and IE, in my experience (and, in theory, it should work in any browser that supports the Flash VM, including clipboard access). The second approach uses the ExternalInterface API to call a JS function which uses ActiveX to invoke the Excel COM object. If the JS function is able to load the Excel object, it then calls the object's COM interface directly (via JS functions) in order to create a Workbook and then to load data into its cells. Unfortunately, this approach only works with IE, but it is slick if you can use it. But, having the first approach as a fall-back is a good idea even then, in my opinion.

[flexcoders] Load time, multiple redundant Embed() calls, etc.
Hi, I have inherited some code and it seems to build into a fairly large .swf and takes a very long time to download. Running locally, things go fairly quickly - but not so remotely. Part of this may be due to slow server and net connection - but I am not able to change those any time soon. So, I wonder two things: 1. Are there tools for highlighting cause of slowness of download (e.g., areas of bloat in code)? 2. If the code is rife with [Embed(source=foo.png)] - where same 'foo' is being embedded in multiple files - would cause bloat? And would it be better to have one managing singleton that embedded all images? Thanks! -Eric
Re: [flexcoders] Detect a databinding
Hi Jules, Let me say about my problem. I've developed a class that implements IList interface for implicit pageable approach. This class works fine for one data provider of component. If I use it in two or more components the list become flicker. The problem of this flicker is when one component needs to get itens which is different for other component. The limit page in memory fill itens for one component, all components will receive events collection change, all components will refresh itens so the other component will get other itens and this loop will work forever. My solution was implement 'n' pages for 'n' components, but why could I detect how many components is using this object, the first idea was inspect a bindings? I saw a generated action script for binding, but I couldn't find out any solution. I didn't figure out how it works. There is some undocument API that I didn't understand. The idea of overrinding addEventListener don't work because the system never calls removeEventListener, so the pages which was created will never remove from memory. It is a memory leak problem. I don't have any idea how Flex remove theses listeners. Maybe it is a voodoo approach. :) Regards, On Tue, Dec 2, 2008 at 11:00 AM, Jules Suggate [EMAIL PROTECTED] wrote: Hi Marco, first up you have to ask yourself why you want this feature? There may be another way to solve the problem. However, here's what I know of your specific question... Last time I checked (Flex 3 beta 2) there was no *official* way to inspect the bindings on a component at runtime. However, if you create a component with bindings and load it up at runtime, you will find there are undocumented properties that enable you to do this. Look for a _watchers array -- you will also find it helpful to keep the generated actionscript that the Flex compiler normally throws away so you can read how databinding is implemented. The properties above are not part of the public API, so could change at any time. In fact, IIRC some of the very binding properties I just mentioned may even have been deprecated in the final Flex 3 release... proceed with caution. Which is why I ask what the actual problem is you are trying to solve -- perhaps the list can help you come up with other ideas :-) For example, your idea of overriding addEventListener is cunning -- perhaps that solution can be explored further.

Re: [flexcoders] any overhead for calling simple getters?
There's *some* overhead, but properties are part of the VM, so it's not
going to be much.
Also, keep in mind, anything that's [Bindable] without
[Bindable(eventName)] is going to have a get/set pair generated by MXMLC,
even if you've already written a get/set pair.
Personally, I only ever use the _privateVar reference internally when
there's some voodoo in the getter (like construction logic for first access,
or something) I need to work around in some circumstances.

Re: [flexcoders] Re: ItemRenderer, mislabels scrolling

But it wasn't. Infact, this.listData.label was the old information. But when
entering the renderData function, it is the new value. This only serves to
confuse me even more. It's like the binding never happened.
I tried both of these:
BindingUtils.bindProperty(this.creativeLinkButton, label, this, [listData,
label]);
BindingUtils.bindProperty(this.creativeLinkButton, label, this.listData,
[label]);
-
Sorry bout the colors and font, pasted from eclipse.
Also, I looked into this.data. I set a break in my code and mx.core.Container
to see not only the value passed into the set data function but to see when
things are kicking off. Well, the data is not being set until after my code
runs. The correct information is passed into the setter, but not at the right
time.
Perhaps I can use the data change event that is dispatched to update my
values. Any other ideas?

I've had similar issues.
One of the things I've found is that it is important to reduce the
steps between this.data, or this.listData, and the property you're
populating.
If you can rewrite so that you bind directly on this.listData.label,
rather than set the value of 'value' and bind on 'value', I
think
you'll probably be okay.

Subject: [flexcoders] ItemRenderer, mislabels scrolling
When scrolling, the labels on the grid turn into those that the
recycled item renderer used. I tried using this.data to overwrite
the values every time. The new listData object has the correct
label and so I thought it was working, but there is a url I need in
the current rows' XML for the button click to work and accessing the
this.data gave me the old results. I then thought I could use the
row index in listData but quickly found that the row index is always
the same when scrolling down or up, the end or the begining of the
grid. So it's not really the row index of the XML but the grid.
Seems overwritting the values wasn't quite the answer.
There is a variable in listData called item. I see it in the
debugger but the compiler won't let me access it. This is the XML
for the row. So, in short, how can I access this 'listData.item'
or
find out the actual XML row I am on. Actually, any suggestion would
be great. Banging my head on this one all day.
And thanks.

_listData = DataGridListData(blData);
renderData();

If it is an Array, what is it an array of? (dynamic objects, scalar values,

Hi Adrian, As far as I know, you can't allow editing of specific cells/rows by default. You can however add an event listener for the itemEditBeginning event. In the event handler function, if the cell/row meets you're editable criteria, allow the function to set the editedItemPosition property. Otherwise, call the preventDefault() method, to prevent editing. I haven't tried this for ADG, but maybe this will help. -TH --- In flexcoders@yahoogroups.com, Adrian Williams [EMAIL PROTECTED] wrote: Hi All, I have a new question that I haven't seen anyone hit yet.

RE: [flexcoders] BlazeDS - Best practice for determining if server session is invalid.
Hi Fotis, The AMFChannel (and its Secure variant) define a 'hidden' method that you could override to get access to the jsessionid value that is returned to the client at connect time for your current server session. Here's the method signature: override public function AppendToGatewayUrl(value:String):void You'd want to override in your own custom subclass of AMFChannel, invoke super, and then parse and store that value somewhere for use in your file upload handler. The method name dates back to Flex 1, and will likely remain undocumented, but go ahead and log an ECR to have the value exposed as a bindable public property on the channel: https://bugs.adobe.com/blazeds/ Thanks, Seth From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Fotis Chatzinikos Sent: Thursday, November 27, 2008 5:11 AM To: flexcoders@yahoogroups.com Subject: Re: [flexcoders] BlazeDS - Best practice for determining if server session is invalid.

Re: [flexcoders] clear the cache
Depends on the browser you're using. Clearing the cache is all you should have to do, but depending on whether you are sitting behind a web proxy even that might sometimes not be enough. In my experience, web proxies are a frequent source of developer frustration (especially MS proxies). Sometimes putting a query string on the end of your request can help, eg http://www.yoursite.com/myapp.swf?foo=bar You can then randomise this which can help if you're behind a bad web proxy. In addition, if you have control over the server environment, you can set the no-cache headers when serving your files. This should stop your browser holding onto them (and ought to also stop web proxies doing the same).

The context root is not something that the swf can automatically substitute

If you're using MXMLC at the command line, or FlexBuilder, add a the

Subject: [flexcoders] ItemRenderer, mislabels scrolling
When scrolling, the labels on the grid turn into those that the
recycled item renderer used. I tried using this.data to overwrite
the values every time. The new listData object has the correct
label and so I thought it was working, but there is a url I need in
the current rows' XML for the button click to work and accessing the
this.data gave me the old results. I then thought I could use the
row index in listData but quickly found that the row index is always
the same when scrolling down or up, the end or the begining of the
grid. So it's not really the row index of the XML but the grid.
Seems overwritting the values wasn't quite the answer.
There is a variable in listData called item. I see it in the
debugger but the compiler won't let me access it. This is the XML
for the row. So, in short, how can I access this 'listData.item'
or
find out the actual XML row I am on. Actually, any suggestion would
be great. Banging my head on this one all day.

[flexcoders] Unformatting currency values - best practice?
What is the best practice or a good recommendation for formatting currency values and then removing the currency formatting for saving to the database? Here's what I have attempted to do so far. It works - but only if the user enters plain old numbers - if they add any currency symbol or thousand separator, it fails. I have a form which has some textInput's that are formatted with currencyFormatters. I initialize each textInput's .data property to 0. The textInput displays formatted currency amounts from xml data retrieved from the database. On the focusIn event, the text property is assigned to the textInput's .data property, so the value stays the same but the formatting is gone. And when a change event fires, the unformatted text in the textInput gets updated to the data property as well. On the FocusOut event, the currency formatting is re-applied. When I save to the db, I use the textInput's .data property. So for the most part this works, but fails if the user enters any currency symbols. Is there a good class or function someone could recommend to take a currency value in a textInput and strip out all the extra formatting characters? I am also trying to implement localization, so the various currency symbols will be different depending on the locale. Thanks

In your labelfunction logic, you are not using any values from the

labelFunction is to use the row item properties to build a string to

Subject: [flexcoders] ItemRenderer, mislabels scrolling
When scrolling, the labels on the grid turn into those that the
recycled item renderer used. I tried using this.data to overwrite
the values every time. The new listData object has the correct
label and so I thought it was working, but there is a url I need in
the current rows' XML for the button click to work and accessing the
this.data gave me the old results. I then thought I could use the
row index in listData but quickly found that the row index is always
the same when scrolling down or up, the end or the begining of the
grid. So it's not really the row index of the XML but the grid.
Seems overwritting the values wasn't quite the answer.
There is a variable in listData called item. I see it in the
debugger but the compiler won't let me access it. This is the XML
for the row. So, in short, how can I access this 'listData.item'
or
find out the actual XML row I am on. Actually, any suggestion would
be great. Banging my head on this one all day.
And thanks.
Here's some code:
public function get listData():BaseListData{
return _listData;
}
public function set listData(blData:BaseListData):void{
_listData = DataGridListData(blData);
renderData();
}
private function renderData():void {
var columnIndex:int;
var xmlRow:XML;
columnIndex = this.listData.columnIndex;
xmlRow = XML(this.data);
/*
* I added this to get at the item.
try{
if(this.listData.item != null){
xmlRow = XML(this.listData.item);
}
else{
xmlRow = XML(this.data);
}
}
catch(e:Error){
xmlRow = XML(this.data);
}
*/
this.value = this.listData.label;
if ( value == [multiple] ){

Re: [flexcoders] Load time, multiple redundant Embed() calls, etc.
Anytime you Embed anything, you're including it within your swf. It may get compressed a little bit, but you're still embedding it. That means your SWF file will contain all of the images that you used [Embed(source=foo.png)] on. Using Embed is not like HTML where you have your images in a directory and then your swf calls them at runtime. Also, use vector graphics as much as you possibly can.

Running locally, things go fairly quickly - but not so remotely. Part of this may be due to slow server and net connection - but I am not able to change those any time soon. So, I wonder two things: 1. Are there tools for highlighting cause of slowness of download (e.g., areas of bloat in code)? 2. If the code is rife with [Embed(source=foo.png)] - where same 'foo' is being embedded in multiple files - would cause bloat?

In your labelfunction logic, you are not using any values from the passed

Value10 as 10 entries in the list but with my code it is showing

Use the devicesCollection directly as the dataProvider:

Then nvrsInPoolList.selectedItem will contain the *entire xml node* and

[flexcoders] Why no initial FlexEvent.SHOW event dispatched?
I was wondering why a flex control or container does not dispatch a
FlexEvent.SHOW when showing the first time? Given this code:
mx:Panel
id=panel
show=Alert.show('I am showing')
creationComplete=Alert.show('I was created')/
mx:Button
click=panel.visible = !panel.visible
label=Show/Hide/
When the panel Panel is constructed, the creationComplete is fired
and I see my Alert I was created. But I DO NOT get the Alert I am
showing.
If I then click the button to hide it and click it again to show it, I
am getting the show event.
Why no show event initially?
This applies equally well to TitleWindow, Button, Box, ...
[flexcoders] Preserve state in TitleWindow - mxml bind problems
I am loading data in a popup title window and then I'd like to reuse
that title window instance with all the loaded data an user input data
any time the user clicks the button to pop it up. I'm having trouble
with bound fields...
I implemented it using an instance of a custom TitleWindow that is
referenced from the main app, and then use addPopup/removePopup to
show/display it. In the example below, click the button to pop up the
TitleWindow. Type any text into the TextInput. Then in the ComboBx
either select original2 from the dropdown or click to change the
dataProvider. Close the popup and reopen and you will see that the
text you entered into popup is still there, but any change made to the
combo box has been wiped out.
Is this a bug? If this is how it is supposed to work, can someone
walk me through why it works this way? Why are the mxml binds
refreshed when the underlying data they are bound to did not change?
Why are the mxml binds wiping out the user entered changes? Is there
any way to prevent this bind refresh from happening?

[flexcoders] Displaying Yahoo Finance Data in Flex
I have a Flex application that reads stock data from download.finance.yahoo.com http://download.finance.yahoo.com/ , which takes various parameters and returns CSV formatted text. This is the site I used as a reference. (http://www.gummy-stuff.org/Yahoo-data.htm http://www.gummy-stuff.org/Yahoo-data.htm ). I have been hoping to improve upon an old classic ASP application that relies on a data file created nightly by a service that runs on one of our servers. I'd prefer to go right to the Yahoo source with the Flex application. The application runs on my desktop when accessed from the file system, but fails with a security error when I run it from a Web server. I suspect the issue may be a cross-domain issue, but I've read elsewhere on the Internet that Yahoo has a cross-domain file set up for that feed. Could I have been mislead by the Internet!? [:)] I've put this application with view source enable on my personal Website http://www.frontlinewebdev.com/StockQuotes/StockQuoteDisplay.html in case anyone can look at it and advise me about getting it working. I will appreciate any help that can be offered. Thanks, Kevin

When a UIComponent is set to visible for the first time by the
LayoutManager, the SHOW event is suppressed. The CREATION_COMPLETE
event fired immediately after that call to setVisible, so you should
be able to achieve whatever effect you're going for by registering the
same function to listen for both the SHOW and CREATION_COMPLETE events.

RE: [flexcoders] any overhead for calling simple getters?
You can measure the difference. It is essentially function call overhead. See

So, over a million fetches you'll save by using _myVar, but consider that if
someone subclasses and overrides, _myVar may not be what you want.

There's *some* overhead, but properties are part of the VM, so it's not going
to be much.
Also, keep in mind, anything that's [Bindable] without [Bindable(eventName)]
is going to have a get/set pair generated by MXMLC, even if you've already
written a get/set pair.
Personally, I only ever use the _privateVar reference internally when there's
some voodoo in the getter (like construction logic for first access, or
