Re: [Flashcoders] survival off eventlisteners on class instance redeclaration?
Hello :) The event listener is registered in a collection (array or other data object) in the instance ( you use the event model of the AS3 framework in Flex ? or the event model in the mx AS2 library ?) If you destroy the instance your registration is canceled because the collection is a property of the instance. PS : you can use the event model in AS2 or AS3 or SSAS(JS) of my openSource framework VEGAS : http://code.google.com/p/vegas/wiki/VegasTutorialsEvents To install VEGAS : http://code.google.com/p/vegas/wiki/InstallVEGASwithSVN EKA+ :) 2007/6/1, Latcho [EMAIL PROTECTED]: Hi list, IfI attach e new instance of a class to a *var myClass*=new friendlyClass() and then attach an eventlistener to it classHello.*addEventLister*(greeting,sayHello) now say that, after a while I want to overwrite the myClass variable with a new and fresh instance of the same *myClass*=new friendlyClass() now my question: will the eventlistener still work or do I have to redeclare it again ?

RE: [Flashcoders] Flash CS3 Prof copy: missing Tree component.
Adobe has put the axe to the tree component and many other components requiring you to use Flex if you want to use them. Which is the prod that finally has me looking seriously at Silverlight this weekend. We have money and projects set aside for our first forays into CS3, but this makes me pause.

[Flashcoders] AS 2 Delegate question
Hi, a question.
I'm talking about AS 2.
Inside a method of a class I've:
btnCollection.onRollOver = function() {
// here this is the button
var t = Number(this._name.substr(1, 1));
//
Mouse.hide();
//
cRef.cursor._visible = true;
startDrag(cRef.cursor, true);
//
cRef.setRotation(cRef.curPos[t]);
};
btnCollection is previously created (in the same method), this way:
for (i=0; ibtns; i++) {
var btnCollection = targetLevel['c'+i+'_btn'];
}
cRef is previously created this way:
var cRef = this; // it stores a reference to the class.
The var t registers a number contained in a button name (I use that
number to perform various tasks).
This is perfectly working, but now I want to use the Delegate class.
So, I did the following:
btnCollection.onRollOver = Delegate.create(this,
btnRollOver(btnCollection));
after having built this method:
private function btnRollOver(whichBtn) {
var t = Number(whichBtn._name.substr(1, 1));
//
Mouse.hide();
//
cursor._visible = true;
startDrag(cursor, true);
//
setRotation(curPos[t]);
}
nothing works like before.
That is: I probably easily get the class reference but I've lost the
reference to the single button...
I even tried (with no results):
1. btnCollection.onRollOver = Delegate.create(this,
btnRollOver, btnCollection);
2. changing btnCollection to be a class variable (not a local one);
Please, can you help me better understand this issue? What am I doing wrong?
Thanks!

Re: [Flashcoders] AS 2 Delegate question
Well, what I understand about the Delegate class, is that you can´t send any parameter through the Delegate.create method, any parameter you want to pass, must be send by the event. btnCollection.onRollOver = Delegate.create(this, btnRollOver); In this case the delegate will send to the btnRollOver function only the parameters of the event onRollOver. You will have to find another way to solve this problem... maybe extend the MovieClip class, or maybe it could be better to not use the delegate. I hope this could help. ___ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com
Re: [Flashcoders] Best Practices question...
It is called encapsulation. No one should know how a class does its magic. The external classes are programmed to the interface (methods)(preferably to an interface class rather than directly to the implementation) , they are not allowed to peek inside. What if you find a better way to persist the data or change your coding standards for variable names? If you have allowed/encouraged others to access your classes' properties directly, their code will now fail to function. How do you know who to warn or what other classes are at risk; your code has no links to who calls it. Using getters and setter for anything other than Inversion of Control is probably not a good thing either for the same reason and do not normally appear in the Interface class. If they do, you are committed to respecting their names as long as you support the interface. Maybe OK to ignore encapsulation if you are a one man show building small demo apps but if you are building something serious with a team or building something that others will use and maintain you have to be careful. It is a good practice to get into so that when you build something significant, you already have the coding practices that will make people respect your work. Ron Steven Sacks wrote: And since we're talking best practices, you don't have any public instance variables anyhow, hmm? :) I don't know what best practice you're referring to that claims that you shouldn't have public instance variables.

Re: [Flashcoders] Flash CS3 Prof copy: missing Tree component and Web Service.
You know what's funny about the web service component missing from flash cs3? It's actually in the help documentation as part of flash 9 CS 3: Web services Adobe® Flash® CS3 Professional includes the WebServiceConnector component that lets you connect to remote web services, send and receive data, and bind results to components. This lets Flash developers quickly create Rich Internet Applications without having to write a single line of ActionScript. You can consume remote web services by using WebServiceClasses, which can require writing complex ActionScript. Yet it's nowhere to be found in flash cs3 professional. Personally I dont care about the component as much as I do the classes themselves. Adobe?

If you open/create an ActionScript 2.0 document, the WebServiceConnector and all other Data components are still available. Those are the same ones as in the Flash 8 IDE.

Or you could use another Delegate class. There is the Proxy class I
believe (can't remember who did it) and the one I use the most is the
one on dynamicflash.com
http://dynamicflash.com/2005/05/delegate-version-101/
You can pass parameters in the Delegate call
myButton.onRelease = Delegate.create(this, myFunction, param1, param2, ...);

Re: [Flashcoders] AS 2 Delegate question
Create a custom Button component that has public methods and properties that
you can access.
Have your custom Button dispatch a click event, just like the v2 Button
component does.
Others might suggest to use a Proxy class that lets you pass extra parameters,
I'd suggest not to do so.
Simply create your own Button and you'll have all the power you need.

public var removeEventListener:Function;
public var dispatchEvent:Function;
And I usually set the events on the Class itself, but use a child movieclip
(which you could see in the screencast).
Someone (not necessarily you) could set events from outside the instance,
messing up your component.
var box = this.attachMovie ( 'box', 'box', this.getNextHighestDepth());
box.onPress = Delegate.create(this, boxPressHandler);
It's no big deal if you will be the only one who will ever use the component.
You'll just have to remember not to use any of the
MovieClip events from outside the instance.
I know it sounds silly, because that's why you created the class in the first
place, but when you distribute alot of components it's
kinda out of your hands ;-)
You'd be surprised how many people drag a Button Component from the components
panel on stage and then go:
myButton.onRelease = function(){}
rather than using addEventListener(click, handler);
