RE: [flexcoders] Is it the right way of using dispatchEvent?
Hi,
We declared a metadata before class defination. If compiler
while parsing MXML code sees it, it generates the required actionscript code for
you, which you had to do yourself in Flash.
Not sure, why isn't it workin for you? Can you post the
code.
Any component extending UIComponent has event dispatching
capablity.
Making components in Flex is much easier than making in
Flash authoring.

Hi Abdul,Thanks a lot for giving breif description on
"dispatchEvent".
One more doubt in this, we declared event before imprting specific
classes.Why is it so? I tried doing it in class, but not
successfull.What is the reason?
And at the same time, creating a pure UIComponent in Flasg is a bit different
from that in FLex??Dont we use addEventListener in flex?
Thanks a lot to one and all.

Is it the right way of using dispatchEvent?
Hi Flex coders,
Thanks a lot to all group people for solving my problem on "Issue on
Accordion reference".
I am stuck up with one more problem.
Here is the problem,
I have a simple mxml file which uses a component(circle.as) , extends
UIComponent.
OnPress of this circle I want to invoke a method that user has
provided.
i.e, I included "circle" component in my xmxl in the following way.
circle xmlns:circle="*" cirPress="fun"/
So here "circle" is an as component which has cirPress event
which has to invoke fun method in mxml file.
Here is the code of mxml file:
//**
?xml version="1.0" encoding="utf-8"?mx:Application
xmlns:mx="
http://www.macromedia.com/2003/mxml" xmlns="*"
mx:Script
![CDATA[ function
fun(){
mx.controls.Alert.show("Event
dispatched!") }
]]/mx:Scriptcircle xmlns:circle="*"
cirPress="fun"/
/mx:Application
//**
Here is component (circle.as)
//**
// ActionScript Documentimport mx.core.UIComponentimport
mx.utils.Delegateimport mx.events.*class circle extends
UIComponent{public var
dispatchEvent:Function[Embed(source="cir_sym.swf",symbol="cir_sym")]
var cir_sym:String;var
obj:Objectvar cirPressfunction
circle(){}function
init():Void{super.init();EventDispatcher.initialize(this);}function
draw():Void{
super.draw();}function
createChildren():Void{obj =
attachMovie("cir_sym","cir_sym",1);addEventListener("cirPressed",Delegate.create(this,tempFun))}
function
tempFun(){eval("_root."+cirPress).call()}function
onPress():Void{dispatchEvent({type:"cirPressed"})}}
//**
Here the above works well!!!
But problem is I shouldnt use "_root." to
invoke the method! (coz method my be in a class/somewhere.
So everytime method may not be in
root)
And please suggest me, is it the right way of using
dispatchEvent()?
I really appreciate one's help on "how to use
dispatchEvent in appropriate way".
Thanks in advance!

Ramu

RE: [flexcoders] Is it the right way of using dispatchEvent?
Hi,
When you extend UIComponent, it comes with event
dispatching capabilities. So you don't need to use
EventDispatcher.initialize(this) kind of mixin.
You need to add [Event("eventName")] metadata in your
class/component and just use dispatchEvent(..) method directly. No need to use
Delegate inside your class, compile generates the code for you with right
scope.
Also you don't need to execute the event-handlers in your
code by getting the reference of event-handler. Everything is done
automatically...
Check out following link to see how to dispatch event
correctly. You probably need to less code that you write than you write
pure Flash becauseFlex makes your life little easier
:)

If you still have any problem, let us
know.
