[Flashcoders] How to set button event listeners within a class
Hey, thanks for checking this. I am writing a class where the
onRelease event of the button is handled within the class. This is so
I can make a class that can be reused across re-skinned FLAs just by
passing the button instance to the class (so I don't need to assign a
method of the class to it). I think I may be going about this the
wrong way as I am getting lots of error messages in the compiler like:
There is no method with the name 'super'.
If someone could point me in the right direction here it would be a
massive help, I'm worried I may be barking up the wrong tree or
trying to do something that isn't possible (or sensible!).
Thanks guys and have a good weekend,
Ali
My class code looks like this:
/Send.as
import mx.controls.Button;
class Send extends XMLSocket {
private var sendBtn:Button;
function setSendBtn(mySendBtn:Button) {
trace(send button received:+mySendBtn)
this.sendBtn = mySendBtn;
this.sendBtn._visible = false;
this.sendBtn.onRelease = function() {
trace(-- send pressed );
sendHandler()
};
}
function sendHandler(){
//send events go here
trace(sendHandler called)
}
}
The code in my FLA is:
import Send;
var mySend:Send = new Send();
mySend.setSendBtn(my_btn)

RE: [Flashcoders] How to set button event listeners within a class
You need to use Delegate to keep your scope within the class:
import mx.utils.Delegate
class MyClass
{
//stuff
private function setActions():Void
{
myButton.onRelease = Delegate.create(this,
myOnRelaseHandler)
}
private function myOnReleaseHandler():Void
{
super()
}
}

Re: [Flashcoders] How to set button event listeners within a class
Use some kind of delegation (e.g. mx.utils.Delegate). (off: using this is not required in AS2 classes) sendBtn.onRelease = mx.utils.Delegate.create(this, sendHandler); Attila ___ 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

You would only use super() if you're extending. It sounds like he was using
composition, but thinking of inheritance.
