Re: [Flashcoders] increasing real memory use
Get rid of the nested functions in loadNewImage()
Assign the enterframe event to a method of the class, using Delegate and make
sure to keep a reference to the handler so it can be
removed.
Make the class itself the MovieClipLoader listener, rather than creating a
seperate listener.
// pseudo code
import mx.utils.Delegate;
class classes.Twee {
private var movieLoader:MovieClipLoader;
private var enterframeDelegate:Function;
function Twee() {
movieLoader = new MovieClipLoader()
movieLoader.addListener(this);
enterframeDelegate = Delegate.create(this, this.enterframeHandler);
}
function loadNewImage() {
var image_p:MovieClip = root_p.attachMovie("void", "image_mc", 0);
movieLoader.loadClip("2246.jpg", image_p)
}
function onLoadInit(target_mc:MovieClip) {
root_p.onEnterFrame = enterframeDelegate;
}
function enterframeHandler() {
// do stuff...
//and eventually remove handler
root_p.onEnterFrame = null;
}
}
I'm not very fond (mildly put) of the usage of _root and the movieclip chaining
going on.
I'd probably go for event dispatching from each class (Een, Twee, Drie) when
they're done with whatever they're supposed to do, to
which the Application listens. So the Application takes care of the chain,
rather than each seperate class.

[Flashcoders] increasing real memory use
Hi list,
I created a kioks application that needs to display data (text and images)
24/7. The flash projector file however uses more and more real memory from
the start on.
I therefore created a simple version of it as can be seen in the code below.
It contains four classes: Application.as, Een.as, Twee.as and Three.as.
When this simplified version runs the task manager (windows) or activity
monitor (mac) reveals a data leak even though I clear up vars and listeners.
The code is pretty simple, still I can't find out for quite a while now what
the problem can be.
Regards,
Tom
