[flexcoders] Any difference between instantiating in declaration vs. init()
Hi,
Is there any difference between initializing a variable in the declarations vs.
in the creationComplete function?
private var scrollTimer:Timer = new Timer(500,1);
or
private var scrollTimer:Timer;
private function init():void {
scrollTimer = new Timer(500,1);
}
When/Why should I use one vs. the other?
thanks,
Re: [flexcoders] Time Difference between two columns in DataGrid using itemrenderer
I think you would find it better to do the calculation on the database itself. All database have a lot of date/time diff functions which you can use. That way, you all simply bind the data retrieved in your datagrid without the need for calculating it. hth From: Don Kerr fusionp...@yahoo.com To: flexcoders@yahoogroups.com Sent: Monday, 29 June, 2009 8:51:22 Subject: [flexcoders] Time Difference between two columns in DataGrid using itemrenderer I have two columns in a datadrid, startTime (e.g. 04:30 PM) and endTime (e.g. 06:00 PM).

You could also look at using the Flex Date Utils on RIAForge. But you'll still need to turn the strings into valid date objects first. -- Thanks, Tom Tom McNeer MediumCool http://www.mediumcool.com 1735 Johnson Road NE Atlanta, GA 30306 404.589.0560

Re: [flexcoders] Performance difference between ArrayCollection.removeAll() and ArrayCollection.source = []
Hi Alex,
Thanks for responding. Should this be tracked as a bug? I think there may be
a better way of handling this:
On removeAll() you can set a flag like removeEventListenersPending = true,
copy the old elements to a temporary new array and run through the it in
smaller sized increments (removing event listeners from say 40 objects every
enterframe using something like calllater). In the meanwhile if a property
change event is fired, you can see if the flag is set and if so make sure
the item is in the current source array and not the temp array. When all
objects in the temp have had their event listeners removed, set the
removeEventListenersPending = false.
I think the current implementation may be causing a lot of performace issues
since a lot of people may be using ArrayCollections for large data sets
(thats what Flex is great for :) ) and may not know of the penalty of the
removeAll().
thanks

Looking deeper into the removeAll function and following the hierarchy to

calling a function to remove the propertyChange listener.
Why is this implemented this way ? Is there any reason I shouldnt just use

RE: [flexcoders] Re: Difference in player behaviour between IE and Firefox with SSL?
I had the same issue (I think I posted it to this list before, solved it and
posted my solution, but never saw my solution sent).
Anyway, I'm running php, and I did the following before outputting anything:
ob_start();
ob_get_clean();
header(Cache-Control: );
header(Pragma: );
session_cache_limiter('public');
session_start();
And that solved my problems entirely.
Took me 2 days to figure this out =(
Good luck all!

I think I have solved this (with much pain and a m oment of exhileration).
There is a difference in the browsers, but not in the player. IE
requires that the add-no-cache-headers property is set in the AMF
channel definition, Firefox doesn't care:
add-no-cache-headersfalse/add-no-cache-headers
Here is what mine looke like...
channel-definition id=dsl-amf
class=mx.messaging.channels.SecureAMFChannel
endpoint
uri=https://{server.name}:8443/{context.root}/messagebroker/amf;
class=flex.messaging.endpoints.SecureAMFEndpoint/
properties
polling-enabledfalse/polling-enabled
add-no-cache-headersfalse/add-no-cache-headers
/properties
/channel-definition
Suddenly both IE and FF work just fine over https.
I'm posting in the hope that some other poor soul won't spend 4 days
staring at this issue and might just bump into this post.

[flexcoders] Re: Difference between getChild and getAtomationChild
I understand that it is a method of the IAutomationObject. But there is still something that I do not figure out. I have created an adapter that enables me to take advantage of the automation package and replay events on a Flex application I have created. With this application all the display components have automation children. But with a mock class I have used to test the adapter, where I just create a class that extends Application and add some panels and buttons, none of those have automation children only regular children. (Both projects implements the automation.swc and automation_agent.swc. And all components are UIComponents, which implements IAutomationObject) What in Flex decides if a object has automation children or regular children? Thank you --- In flexcoders@yahoogroups.com, Peter Hall [EMAIL PROTECTED] wrote: Correct. getAutomationChild() is a method of the IAutomationObject interface, and only returns children that also implement that interface. IAutomationObject is part of the mx.automation package, which is designed for automated testing. So basically, it's a filter for testing tools so they only have to look at objects that can be automated. The Flex extension for Mercury QTP is currently (I think) the only commercial tool that makes use of it.

I think you would get your best answer by spending ten minutes on the adobe web site looking at the examples that are presented there including the walkthroughs of making a simple application. Flex has a markup language (similar in some respects to JSP, though different in others) that you can use to create applications and components, in preference to the timeline (which it doesn't have). If you code Flash actionscript and don't use the timeline, the main difference will be Actionscript 3 versus Actionscript 2 and a different class library/API. Paul Be a PS3 game guru.

RE: [flexcoders] The difference...
There should be a ton of articles online discussing this and I see Abdul gave a good summary before. Here's my quick summary here... both Flex and Flash applications are ultimately compiled down to a SWF file and run in the Flash Player. They both use ActionScript to write programmatic logic and they can make use of graphic, video and audio assets. However, the way in which the applications are built is very different. Flash applications are typically built with the Flash Authoring tool and focus around stages, timelines, labels and script blocks to control program flow. Flex applications are typically built with Flex Builder; the concept of a timeline is effectively absent. Developing Flex applications should feel like a hybrid between web development and traditional GUI application development, but with a rich set of pre-built components. The Flex developer uses an XML language to declaritively layout the UI and writes formal classes to extend existing components or write completely new logic. From Flex 2 we target Flash Player 9 and ActionScript 3.0.

Yes, but this still requires knowing if your variable is a date or not. A straight primitive == would not. To test for that would only be 2 extra lines of code but it's still a special case that you have to put everywhere. My point is only that having to treat Dates differently from Numbers and Strings and use functions for comparison is inconvenient, no matter how simple it actually may be. This could be improved by making them (or a new class) a primitive. Of course if a future version of ActionScript allows users to override operators in custom classes, I can create my own [primitive-like] Date class.

RE: [flexcoders] Re: Difference between two dates
if a future version of ActionScript allows users to override operators in custom classes I've heard that the committee designing the next version of Ecmascript is considering this. If they add this language feature, we'll likely follow their lead. - Gordon From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Kelly Birr Sent: Monday, June 26, 2006 3:06 PM To: flexcoders@yahoogroups.com Subject: RE: [flexcoders] Re: Difference between two dates Yes, but this still requires knowing if your variable is a date or not. A straight primitive == would not. To test for that would only be 2 extra lines of code but it's still a special case that you have to put everywhere. My point is only that having to treat Dates differently from Numbers and Strings and use functions for comparison is inconvenient, no matter how simple it actually may be. This could be improved by making them (or a new class) a primitive. Of course if a future version of ActionScript allows users to override operators in custom classes, I can create my own [primitive-like] Date class. Then no-one will have to hear me complain. :) - Kelly -Original Message- From: [EMAIL PROTECTED]ups.com [mailto:[EMAIL PROTECTED]ups.com] On Behalf Of Tim Hoff Sent: Monday, June 26, 2006 2:42 PM To: [EMAIL PROTECTED]ups.com Subject: [flexcoders] Re: Difference between two dates Hi Kelly, For simple comparisons there is are compare() and dateCompare() functions in the mx.utils.ObjectUtil class. -TH --- In [EMAIL PROTECTED]ups.com, Kelly Birr [EMAIL PROTECTED]. wrote: Yes thank you, this is helpful. I did already have some routines built to do this but this one is a bit better. Never-the-less I still believe the language would be improved by making a Date primitive. Just because we have workarounds does not mean we should settle for them. The fact still remains that this requires extra code, especially if your trying to do a comparison between 2 variables whose actual types you don't know (or care) and just want to know if they are equivalent or not.

I think I need more coffee
The following code (which I'm sure is correct!), returns around
2.8 when
I'm expecting around 3.2. Anyone spot my error?
public static function getMonths(startDate:Date, endDate:Date):Number
{
if (startDate endDate)
{
var tmp:Date = endDate;
endDate = startDate;
startDate = tmp;
}
var numMonths:Number = 0;
// Get number of months in years
numMonths += (endDate.fullYear - startDate.fullYear) * 12
numMonths += endDate.month - startDate.month;
numMonths += (endDate.day - startDate.day) / 30; // This needs
fixing
return numMonths;
}

[flexcoders] the difference between List.getItemAt and List.getChildAt
Hi, I wonder what is the difference between List.getItemAt() property and List.getChildAt() method. When I create List items with addItem the List.getChildAt() gives me undefined value and getItemAt() gives me the correct item. why? krzysiek Yahoo!

Re: [flexcoders] the difference between List.getItemAt and List.getChildAt
the two APIs are not intended to be similar, although perhaps the names themselves might lead one to think they are related at first glance. getItemAt() returns the specified item from the list's data provider. getChildAt() is inherited from View which is a base class that provides containment semantics. so MXML components that can have other MXML components within them extend View. /mgk Krzysztof Szlapinski wrote: Hi, I wonder what is the difference between List.getItemAt() property and List.getChildAt() method.

RE: [flexcoders] the difference between List.getItemAt and List. getChildAt
List.getItemAt(..) gives you item(data object) from dataprovider. List inherits from View, that's why you see getChildAt(..) method, which essentially gives the reference of child at specified index. Not sure, how it works in case of List.. Does it make sense? -abdul -Original Message- From: Krzysztof Szlapinski [mailto:[EMAIL PROTECTED] Sent: Friday, April 08, 2005 9:54 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] the difference between List.getItemAt and List.getChildAt Hi, I wonder what is the difference between List.getItemAt() property and List.getChildAt() method.

The number of child objects in List needn't match the number of rows being displayed. There's no relation. To see the number of child objects, see the numChildren property. -- [EMAIL PROTECTED] http://manish.revise.org/ Yahoo!
