Re: [Flashcoders] XML loading and parsing problem
OK, my comment about 'this' isn't completely right, but I am certainly right
about the use of Delegate for the XML loader.
You comment about 'this' was completely wrong.. ;-)
You're right if you say that *you don't have to* use Delegate to be able to
access variables outside an onLoad hander, but the fact
remains that the scope has changed, and that's the important part.
When you do this:
var foo = bar;
test.onLoad = function(success) {
trace(foo);
}
you're relying on Flash to look up the variable (which it will) and that's why
it works.
Things also get more complicated/missleading when you do something like this:
var foo = bar;
function loadHandler() {
trace(foo);
}
test = new XML()
// etc..
test.onLoad = loadHandler;
Seeing it like that (nice and together) one could note that the loadHandler
function runs in a different scope than the one it
resides in (the timeline).
But what if the loadHandler function and the onLoad assignment are separated by
100 lines of code?
Then things aren't that obvious anymore and leads to missleading code.
Using Delegate is just one of those best practices and should be used at all
times, even if it kinda works without.

Muzak

If you don't use the Delegate class and try and access the attributes of a
class within an onLoad function, you won't have access
to the class atrributes, so you must use a delegate.
If you don't use the Delegate class on the main timeline and try and access
the variables declared on the timeline you will be
able to access them, so you don't have to use a delegate.
Stick the following code onto the timeline and see how you get on..

You comment about 'this' was completely wrong.. ;-)
Well for lesser beings (from the flash help):
this property
this
References an object or movie clip instance. When a script executes, this
references the movie clip instance that contains the script. When a method
is called, this contains a reference to the object that contains the called
method.
Inside an on() event handler attached to a button, this refers to the
Timeline that contains the button. Inside an onClipEvent() event handler
attached to a movie clip, this refers to the Timeline of the movie clip
itself.
Because this is evaluated in the context of the script that contains it, you
can't use this in a script to refer to a variable defined in a class file.
You're right if you say that *you don't have to* use Delegate to be able
to access variables outside an onLoad hander, but the fact remains that
the scope has changed, and that's the important part.
Well, nobody ever mentioned that - Delegate was proposed as apparently the
only way forward.
When you do this:
var foo = bar;
test.onLoad = function(success) {
trace(foo);
}
you're relying on Flash to look up the variable (which it will) and that's
why it works.
Well that's why *anything* works.
Things also get more complicated/missleading when you do something like
this:
var foo = bar;
function loadHandler() {
trace(foo);
}
test = new XML()
// etc..
test.onLoad = loadHandler;

But what if the loadHandler function and the onLoad assignment are

I don't see what this has to do with delegate. I can use Delegate and still
have 100 lines of code between it and the function.
Using Delegate is just one of those best practices and should be used at
all times, even if it kinda works without.
Well, best practice wasn't mentioned until now. I think kinda works is
actually does work.
The OP was reporting a problem and many people seemed to suggest that
Delegate was going to help solve the problem, something that was entirely
erroneous.
Best practice, fine. Only practice, no.

Subject: [Flashcoders] XML loading and parsing problem
The primary thing to remember is scope.
The onLoad function is running within the xml's scope. The fun function is
running with the scope of the parent class/object.
The fact that fun worked and gallery didn't leads me to think that this is
not the real code, but you are running it in a class of some sort.
Tehnically in your code, the gallery would be global as well as fun and they
should both work, but it sounds more likely that you created your XML object
within the scope of a function - I'm not really sure, but here are my
thoughts..
I'm not sure what version of AS you are running, so there are slightly
better ways to perform this task, but the easy way:
Modify your onLoad to pass this on the fun function and modify the fun to
have a xmlInfo:XML parameter:
gallery.onLoad = function( bSuccess ) { if ( bSuccess ) fun( this ); };
fun( xmlInfo:XML ):Void
{
// perform your XML stuff.
}
As a note, Personnaly to keep my onLoad functions short (since they are
inline) - I like to pass the boolean to the function as well and check the
status there (that way I could do some error handling etc. if necessary).
Hope this helps..
Fruber.

RE: [Flashcoders] XML loading and parsing problem
Delegate is a better solution, Since you didn't specify nor show in the code
what version of AS you were compiling with, the first version was an AS1
soluction.
Delegate is much better, especially if you are using it within a class etc.
So if you are using AS2 or better, then that's a more clean solution.
Thanks - Fruber

Subject: [Flashcoders] XML loading and parsing problem
The primary thing to remember is scope.
The onLoad function is running within the xml's scope. The fun function is
running with the scope of the parent class/object.
The fact that fun worked and gallery didn't leads me to think that this is
not the real code, but you are running it in a class of some sort.
Tehnically in your code, the gallery would be global as well as fun and
they
should both work, but it sounds more likely that you created your XML
object
within the scope of a function - I'm not really sure, but here are my
thoughts..
I'm not sure what version of AS you are running, so there are slightly
better ways to perform this task, but the easy way:
Modify your onLoad to pass this on the fun function and modify the fun to
have a xmlInfo:XML parameter:
gallery.onLoad = function( bSuccess ) { if ( bSuccess ) fun( this ); };
fun( xmlInfo:XML ):Void
{
// perform your XML stuff.
}
As a note, Personnaly to keep my onLoad functions short (since they are
inline) - I like to pass the boolean to the function as well and check the
status there (that way I could do some error handling etc. if necessary).
Hope this helps..
Fruber.

RE: [Flashcoders] XML loading and parsing problem
Omar - also keep in mind all the solutions you are seeing make the
assumption that the xml object is global to the context, there are many
situations where you only want the xml instance to be around for a short
time and keeping it within function scope and then passing a node around or
the parsed version of it around - then you should pass the xml object to
your function, otherwise if you keep it as a class member (or global) - then
all is well.
While I'm not 100% sure, I don't think you can make the xml object within a
function scope and still use the delegate in this fashion. In that case,
you'd need to assign the delegate.create the xml object as the context, with
the function being a class member function. But of course the problem with
that would be you wouldn't have access to your other class members when the
function was called.
Unless someone knows of another way - only the AS1 version will allow you to
encapsulate the xml object (without having it as a class member or global).
Just a few more notes, hope all of it is helpful.
Thanks - Fruber
