Re: [Flashcoders] Re: Handle Leaks in Flash, anyone can help?
Hi James,
you are right, I use a lot of EventDispatcher in the code. Most of the
components throw events which are listened by other components in the scene.
I have lot of components, more commonly, Tree, Scrollpanes, list box,etc
etc..
in my XML if I command the object to be deleted, it gets deleted.
If it were a movieclip in a scrollpane.
i do :
scrollpane.content.unloadMovie();
scrollpane.content.removeMovieClip();
and then i unload and remove the scrollpane itself.
if say, the XML commands the object to be created, i would also add
eventHandlers for the object I created.. eg:
object.addActionListener("enter",Delegate.create(this,enterActionHandler));
I dont remember adding a removeActionListener method when the object is
deleted (the deletion command is sent through the XML, which makes the VM to
delete the object)..I will do that ASAP and see how that helps..
This is a good lead.. Are there anything else associated with Action
Listeners/Event Dipatchers that I missed out?
One more thing, New listeners are NOT added to the existing object during 1
minute intervals,
I add listeners only when I create a new object, in other words, if the
server through the XML commands the client to create an object.
Is there some profiler that will help know if any event that was dispatched
has not been caught by any component/object?
Thanks

RE: [Flashcoders] Re: Handle Leaks in Flash, anyone can help?
Removing the MovieClips or objects does not remove the listeners to that
object. You would have to explicitly remove the listeners first then remove
your MovieClip/object. Otherwise, the reference to the listener will still
exist, thus not get picked up by garbage collection. This could be another
cause of your leak issue.

RE: [Flashcoders] Re: Handle Leaks in Flash, anyone can help?
Varun,
To make sure that any listener are properly removed and the way I usually
handle EventDispatcher, is to first create a private variable for the
delegate.
private var onStatus_func : Function;
Then in an init function or elsewhere prior to adding the listeners:
onStatus_func = Delegate.create (this, updateStatus);
then, adding the listener:
myClass.addEventListener ("onStatus", onStatus_func);
you would then remove it as:
myClass.removeEventListener ("onStatus", onStatus_func);
This is one of the few ways that will properly remove the eventListener. I
tend to keep them in a destroy function to make it easy.
If you are throwing the delegate in as such:
myClass.addEventListener ("onStatus", Delegate.create (this, updateStatus));
myClass.removeEventListener ("onStatus", Delegate.create (this,
updateStatus));
This will not work. It's how the function is referenced. I've done simple
tests with components to verify that it doesn't work.
Hope that helps.
