Re: [Flashcoders] Event Handling in ActionScript 3
just can't think of one now.
The most common case where you do not extend the EventDispatcher is when you
need to extend the Proxy class in order to catch dynamic method and property
calls. In that case
you need to extend a class that does not extend EventDispatcher itself
you can do something like this:
public class Test extends Proxy implements IEventDispatcher
{
private var _eventDispatcher:EventDispatcher;
public function Test()
{
_eventDispatcher = new EventDispatcher(this);
};
public function dispatchEvent(event:Event):Boolean
{
return _eventDispatcher.dispatchEvent(event);
};
public function addEventListener(type:String, listener:Function,
useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean =
false):void
{
return _eventDispatcher.addEventListener(type, listener, useCapture,
priority, useWeakReference):void
};
...
};

Re: [Flashcoders] Bundle swf's on server for transport to client
With AS2 this indeed seems tricky. With AS3 you could just zip the stuff, unzip within your Flash application and load the bytes. Your best guess is a tool like swfmill that has the ability to create swf's on the server. I only know of a library in java that has the ability to generate swf's (javaswf). If the content you are loading in is created within flash you might be able to convert it to actionscript drawings (think lineTo and beginFill, etc). This allows you to convert those commands to a text or xml file and run them in your main application. Greetz Erik On 1/30/08, Gert-Jan van der Wel [EMAIL PROTECTED] wrote: Hi list, I'm working on the Flash app of Floorplannerhttp://www.floorplanner.com/tryit/ and we are having some problems with the loading of all the swf's. The Flash app (AS2) consists of 1 main app that loads several forms (the windows you see, like the library). The library holds a lot of furniture elements, which are separate swf's that are loaded one by one. When someone creates a floor plan and adds furniture to it, it's not strange that the design holds more than 50 furniture elementshttp://www.floorplanner.com/vyy1fm/Verdieping/Lekkeeerrr. Though all elements are small swf files, it takes a lot of time to handle all resource requests on our server. So my question is: is there a technique that makes it possible to (dynamically) bundle a set of swf's on the server and transport it to the client? Right now I'm testing with swfmill and it looks promising, but it seems a little buggy... I hope someone can help me out and point me in the right direction.

[Flashcoders] Resizing a background image only.And keeping aspect ratio.
Hello everyone,
Question: (Using actionscript 3)
How to scale just the background image (photograph) fullscreen in the browser
but still keep it's aspect ratio.
All the solutions on the internet seem to still be in Actionscript 2. I'm
using the code below -
-
stage.addEventListener(Event.RESIZE, onStageResize);
function onStageResize(event:Event):void {
picture_mc =
}
--
I've tried stage.stagewidth and scaleX = stage.width; but they all distort the
image when resized.
Anyone have a clue?
Thanks.
Vlado

Re: [Flashcoders] Catching an error from a component
I am not sure how it is possible that the item has been removed from the
display list. I however take your word for it :) Since you can not put a try
/ catch block (or check) around error area the solutions are limited.
My first thought was to extend the component and override the
thumbReleaseHandler, this method is however most likely private and thus can
not be overridden. You could however try this:
scrollbar.addEventListener(MouseEvent.MOUSE_UP, _listener, false, 1);
function _listener(e:MouseEvent):void
{
//check if the scrollbar is part of the display list
if (!scrollbar.stage)
{
//It is not in the display list, stop the event from being dispatched
to the default dispatcher
e.stopImmediatePropagation();
};
};
In the above code you add a listener that has a higher priority than the
internal listener of the scrollbar. Within the listener you check if the
scrollbar has still has a stage reference (which means it is still part of
the display list).
If it has not, you tell the event dispatcher to stop dispatching the event.
Before you try this code I would urge you to check the setup of your
application as it (usually) should be avoidable to have this error in the
first place.

We know this error is fired since the scroll component is non-existent by

I have tried the following:

Re: [Flashcoders] How to call custom method on loaded AS3 swf?
This is the perfect example as to where you would use an interface:
Interface definition:
public interface MyFrameworkInferface
{
function startup():void
};
Class in the swf that is loaded in:
public class MyLoadedClass
{
public function startup():void
{
/stuff
};
};
Accessing the method:
var loadedClass:MyFrameworkInterface = MyFrameworkInterface(
gameLoader.content);
loadedClass.startup();
I just needed to compile the class into my View
In most cases you want to prevent the main application from compiling
specific classes used in swf that are loaded
in. Interfaces are a perfect solution here, they act as the contract
between the loader and the loaded.

Steven, thanks for that link. It's very interesting but, in this case, my
initial instinct and August's suggestion was correct - I just needed to
compile the class into my View and then cast gameLoader.content when I
want
to access its custom methods/properties.
August - you were exactly right! I had tried this before but, what I
discovered was that the game I was loading (authored by someone else) was
throwing a runtime error when I tried to run it and I had misinterpreted
the
error as a problem with my code. Weirdly, this runtime error was not
thrown
when I ran the game on its own! Anyway, I tracked down and fixed the
problem
in the game code and now all is working well.

Re: [Flashcoders] Question about Arrays
I believe it's type * so you should cast it. This has nothing to do with that, hehe. There is a tiny difference beween ClassToCastTo(value) and (value as ClassToCastTo). In the first case a compiler error will be thrown. In the second case the cast will be tried. If it fails the resulting value will be a null value. why is -it- working The pop method is typed as Object. Object is a dynamic class which means you can add properties at runtime. This in turn means that the compiler can not complain about you calling a property that might not exist as you might be adding it 'dynamically' before you call it, Greetz Erik On 1/12/08, Mark Winterhalder [EMAIL PROTECTED] wrote: On Jan 11, 2008 11:34 PM, Mark Lapasa [EMAIL PROTECTED] wrote: I too would expect that it would need to be casted.

Re: [Flashcoders] AS3 type coercion error
The only thing I can think of is that it is most likely
a problem concerning the ApplicationDomain. You probably load the swf into
its own application domain, which means it will use the AbstractPreloader
class of the swf instead of the one in your main application. The solution
here would be to load the swf like this:
var context:LoaderContext = LoaderContext(false,
ApplicationDomain.currentDomain = null, SecurityDomain.currentDomain);
loader.load(my.swf, context);
