[flexcoders] Large XML /w E4X vs. serialized objects /w tree traversal
Hi, I am building an app that deals with a fair bit of people relationship data coming down as XML, so the hierarchical nature of XML actually comes in handy here. I have a few options: one is to serialize each person XML node into an object, and setup the appropriate data structure for hierarchical data traversal (e.g. rooted tree). Another option is to keep everything in memory as XML and accessed the node data via E4X. The third option is to take a hybrid approach, won't consider this route right now unless this appears to be the best. My concern is that instantiating thousands of objects will create a performance issue (happened at another project that dealt with thousands of dto's), not to mention it's very slow to instantiate lots of objects. At the same time, I am not sure how fast E4X is at dealing with large XML. Which approach would you take? Which one is likely to scale better? Large in-memory XML + E4X traversal or data structure with lots of objects + algorthmic tree traversal? - boon

I would choose the class hierachy approach. Write your own classes for relationships, people etc. The pros of this approach: * You do not depend on a datasource: it does not matter where the data comes from ((different) XML sources, remoting [,...]). * You have strong typed objects and you can embed your own events and errors. This means (unit-) testing becomes more effective. The cons: * You have to implement a parser.

Well, here it would be interessting for me how and when the XML object creates its descendants. My approach might be a bit outdated, since i might have the old DOM model in mind.

Instantiating a lot of objects is dog slow as well. Also, there would really be no dependency with the datasource even if we go XML (assuming this is the best option) because either way we have to write code to process/transform the incoming data, in this case it would be just code that transforms whatever format it comes in as into XML. There is also no need for events in this case as well since they are plain vanilla data objects with only public properties in it. - boon --- On Sun, 8/3/08, florian.salihovic [EMAIL PROTECTED] wrote: From: florian.salihovic [EMAIL PROTECTED] Subject: [flexcoders] Re: Large XML /w E4X vs. serialized objects /w tree traversal To: flexcoders@yahoogroups.com Date: Sunday, August 3, 2008, 12:53 AM I would choose the class hierachy approach.

[flexcoders] Re: snapshots of TabNavigator tabs
Hi Danny, Not sure about the snapshots; without seeing some code. But, the children are disappearing because you're creating references (not copies) to the original display objects and then reparenting them with addChild(). You might try this instead; to make a copy: cloneBarChart = BarChart(this.barChartDispaly); instead of : cloneBarChart = this.barChartDisplay as BarChart; -TH --- In flexcoders@yahoogroups.com, dannyvenier [EMAIL PROTECTED] wrote: Hi, Perhaps someone has tried to do this and has figured it out.

[flexcoders] Re: snapshots of TabNavigator tabs
Hi Danny, I've done this where I show thumbnails of the tab content in each tab. The problem I faced originally was similar to what you allude to - initially only the first tab's contents are drawn and the other tab contents are not yet rendered. So how do you take a snapshot of something that is not yet drawn on the screen? The way I got it to work is, after the first tab content is rendered, force calling updateDisplayList() for each of the other tab's content child object passing in the unscaledWidth and unscaledHeight of the first tab child. After all tab contents are created and sized (although not yet drawn on the screen), snapshots using the ImageSnapshot's captureBitmapData() work fine. I do have very custom components and rely less on the Flex fwk for sizing etc. but it should work the same. Hope that helps.

Re: [flexcoders] Air App State Index
It looks like you are trying to put something before the Application
Control Bar
mx:AddChild relativeTo={mainCB} position=before
if you just want to add it after the control bar, a simple
mx:AddChild will work
if you try to make a lay out with anything before the control bar as in:
mx:LinkButton label=Button Before Control Bar /
mx:ApplicationControlBar dock=true id=mainCB.
It puts the button AFTER the control bar

[flexcoders] SWF/Flex security
In preparing for securing the site before I code the main site functions I thought I'd read up a bit on security. I was thinking that flex/swf code could not be decompiled. But then I found this: http://blog.everythingflex.com/2008/02/29/check-you-as3-code/ I'd like to do some remote object validation (adding in another field for the remote object that would verify that the request was coming from my SWF and not someone else's (possibly malicious) code. However, if someone can decompile my SWF files then all of that would be for nothing. What can people say about flex code decompiling and protecting my code from prying eyes? Regards, Scott
Re: [flexcoders] SWF/Flex security
I'll be speaking on this topic at 360 Flex San Jose. At the basic level, you can embed or even encrypt secure information such as usernames/passwords.

[flexcoders] Flex Trademarks: How do we play nice?
Hey guys, Just finished listening to the latest Flexshow with Matt, and realised that when I get around to uploading my new design, putting up more content and launching my blog publicly I'm likely to run afoul of Adobe's crack team of ninja lawyers. Dating a proto-lawyer is frankly all the lawyer I need in my life- so I want to know whom I need to talk to in order to get permission to use the word Flex as part of the name (it's obviously satire, and in no way looks like any *Adobe* logos or trademarks), and how to word the Flex is pwn3d by adobe text. Decided not to email off-list as I'm sure some other people will be interested in the same info! -Josh -- Therefore, send not to know For whom the bell tolls.

I think it came across clearly in Matt's interview, but I'll just reiterate. The Flex dudes are nice and don't like being the bad guys. I've gotten contacted by Matt before for getting into a little trouble (I posted the Flex SDK codebase into a SVN repo before it was officially an open source project). I think the lawyers only get involved after a few yo, that's not really cool type of emails.

Matt mentioned that stuff like the flex show probably falls under the Adobe should do something umbrella but that they haven't pursued the Flex stuff at all. There are a ton of examples, FlexLib, Flex Box, etc etc. So I'd say don't use AIR cause someone seems to get all riled up when it comes to that trademark, but I haven't seen anyone fucked with for using the word Flex.

[flexcoders] Multiple Lists
I have multiple lists and i want one drag to another. The drag and drop is already working. My problem is that i have like 10 lists and any of them can drag to any other. Is there an easy way to set what list it can come from? like list1 can just receive dragable item from list2 and vice-versa. list3 can jusst receive from list4 and vice-versa. list5 from list6. and so on. What is the best way to work with drag and drop between lists? the native one or using the dragmanager? Thanks :p
RE: [flexcoders] Re: Tabbing children from custom item renderer inside List
You'll need more code in keyFocusChangeHandler. It has to not call
preventDefault when it is time to transfer the tab to the next renderer.

Ok, I managed to send the focus to the second numeric stepper, but when
I hit tab again I loose the tab and cannot sent the focus to the second
item in the list on the first numeric stepper.
Now my code looks something like this:
mx:HBox
xmlns:mx=http://www.adobe.com/2006/mxml;

width=100%
height=100%

void {
// lista va fi tot timpul si in toate situatiile
itemRenderer.parent.parent
var parentList : List = this.parent.parent as List;
var parentListDataProvider:ArrayCollection = parentList.dataProvider as
ArrayCollection;
var itemIndex:int = parentList.itemRendererToIndex(this);
parentListDataProvider.removeItemAt(itemIndex);
}
public override function set data (val : Object) : void
{
super.data = val;
}
override protected function focusInHandler(even! t:FocusEvent):void
{
trace(Focu! sHandler );
addEventListener(keyFocusChange, keyFocusChangeHandler);
}
protected function keyFocusChangeHandler(event:FocusEvent):void
{
event.preventDefault();
trace(event.target);
stepperTwo.setFocus();
}
]]
/mx:Script

mx:NumericStepper id=stepperOne
minimum=2
maximum=100
width=46
height=20
cornerRadius=3
nbs! p; backgroundColor=white

buttonMode=true
/
mx:Spacer width=5 /
/mx:HBox
As said before the only components that I am interested in being in the
tabloop are the 2 numeric steppers. Maybe I'm missing something but
when the focus is on the stepperTwo and I hit tab it goes away. I have
no idea how to send the focus on the second item in the list, eg the
first numeric stepper of! the second item...
I have tried to do stuff in the focuOut evt handler for the second
numeric stepper but it doesn't seem to work

Re: [flexcoders] document[value]
AFAIK In an MXML component, document will usually point to the defining instance, which may be the application, or it could be another component. And in actionscript, foo[bar] is the same as: foo.bar So it's just dereferencing a public property of the document object with the name of whatever is in somevalue. -Josh On Mon, Aug 4, 2008 at 12:44 PM, flexaustin [EMAIL PROTECTED] wrote: What does it mean when you see this code? document[somevalue] Is that finding some value in your mxml with the name somevalue?

I got this working, but if it doesnt use the builtin events when i
drop it. I just disapear with the items i'm dragging.
I don't want to create new function to the drop event, i want to use
the builtin one. Any idea why?!
Alex, anything you can help me with this code so i can keep using the
builtin dragdrop events and just specify the list i want to interact?
DragManager.showFeedback(DragManager.MOVE) doesn't seem to be working
if you don't put the DragManager in the Enter event.
