Re: [flexcoders] help w/ setting click events on dynamically created linkbuttons
Use addEventListener() for registering an event handler:
myLabel.addEventListener(MouseEvent.CLICK,
myFunction);You should take time to read about event handling in Flex/AS3 as
it's a basic and very important concept!

RE: [flexcoders] help w/ setting click events on dynamically created linkbuttons
I have looked through the examples, and that’s what is confusing me.
All of the examples show exactly what you have written:
myFunction(event:MouseEvent)
{
Alert.show(“hello world”);
}
myLabel.addEventListener(MouseEvent.CLICK, myFunction);
When I try to do this:
myFunction(event:MouseEvent, myString:String)
{
//do something here
Alert.show(myString);
}
myLabel.addEventListener(MouseEvent.CLICK, myFunction(MouseEvent.CLICK,
“hello”);
I get the following error:
1067: Implicit coercion of a value of type String to an unrelated type
flash.events:MouseEvent.
The problem I’m having is finding the correct syntax to use when passing the
string to myFunction.
Can you point me to the part of the manuals that would help me with that?
Thanks,
Bob

Re: [flexcoders] help w/ setting click events on dynamically created linkbuttons
You can't pass any variables to the handler that way. The event handler
function must have exactly one argument, the event object, or no arguments.
If you need a reference to the clicked button for example, you can get it in
the handler with event.target.Doc:

RE: [flexcoders] help w/ setting click events on dynamically created linkbuttons
I did finally find the syntax this morning:
http://www.adobe.com/cfusion/communityengine/index.cfm?event=showdetailsproductId=2postId=9144
ABCButton.addEventListener(MouseEvent.CLICK,function (e:MouseEvent) : void
{ABCButtonListener(e,myPrivateSpecialObject);});
Using this syntax, I can pass variables to the CLICK event handler. Of course,
since I was iterating through an Array as I was creating the linkbuttons, it
ended up using the value of the last entry in the Array for all of the values.
Argh.
For this task, I’m shifting to radio buttons and a submit button. I think it
will be easier on me.
Thanks,
Bob

RE: [flexcoders] help w/ setting click events on dynamically created linkbuttons
I advise using repeater with a custom clickable component.
Tracy
Goal: Display a list of items using a complex display for each item, and
have each of those items behave like a menu element and respond to a
click anywhere on the item by running a handler function.
One solution is to use a Repeater with a custom component
In the main app or component, declare the Repeater, and the click
handler function.
mx:Application ...
mx:Script![CDATA[
import MyRepeaterItem;
...
private function onRPItemClick(oEvent:Event):void
{
var xmlItem:XML = XML(oEvent.target);
}//onRPItemClick
]]/mx:Script
mx:VBox ...
mx:Repeater id=rp dataProvider={_xmlData} ...
!-- Note we pass in the entire currentItem, and define a click
handler --
MyRepeaterItem xmlItem={rp.currentItem}
itemClick=onRPItemClick(event) .../
/mx:Repeater
/mx:VBox
/mx:Application
And in the component, MyRepeaterItem.mxml:
?xml version=1.0 encoding=utf-8?
mx:HBox mouseChildren=false buttonMode=true click=onClick(event)
!-- The metadata tag below allows us to define an itemClick handler
in mxml, as in the code above --
mx:Metadata
[Event(name=itemClick, type=flash.events.Event)]
/mx:Metadata
mx:Script![CDATA[
[Bindable]private var _xmlItem:XML;
/** Setter function */
public function set xmlItem(xml:XML):void
{
_xmlItem = xml;
//do any special, non-bound ui stuff you want
}//set xmlItem

public function get xmlItem():XML
{
return _xmlItem;
}//get xmlItem
/** Outer VBox Click handler function */
private function onClick():void
{
dispatchEvent(new Event(itemClick,false); //we do not need/want
this event to bubble
}//onClick

RE: [flexcoders] help w/ setting click events on dynamically created linkbuttons
A primary benefit of doing things like this is that you have the entire
item data in the component dispatching the event, and you have access to
that data in any handler via the event.target reference.
So you only need the event, and no other arguments.
