I'm not exactly sure what you are trying to do but I would create two different
events for those functions if events are truly needed.
Also, I would recommend extending the Validator class for your spellcheck (I
think I've seen a spellcheck class out there somewhere).
Depending on what you are trying to do, it may be overkill to use events to
process the information. In my code, I write components/classes around a site
function or table in a DB. If it's a table in the DB I have a remote object in
that class that deals with the different functions like add, modify, and
delete. I then assign a button to calling an actionscript function to process
the DB call using the remoteobject. The only time I use events is when I need
to talk to another class (and it has to be a parent or further up the chain.
Event bubbling does not go to parallel classes.
eg.
<mx:Script>
[!Cdata....
private function getData( intUserID: number):void
{
sameasremotequery( intUSerID );
... process data
}
private function saveData( intUserID: number):void
{
... call remote object here
}
</mx:Script>
<Remoteobject ,,,>
<method id="sameasremotequery" ....>
</Remoteobject>
<mx:Button id="button" name="getdata" click="getData()"/>
There are exceptions to my rule, but for the most part I try to use events
where they are needed.

Subject: [flexcoders] Custom Classes and Custom Events
Hi all,
The last couple of weeks I wrote my first application in Flex. Today I want to
refactor it, meaning : using custom classes and custom events.
I have following :
I created an application with a couple of buttons and with a custom component
(myCustomComp) in it. This custom component is based on a Vbox an contains :
- an HBox (mySearchbar) with a textfield and button
- a datagrid which contains data from a database
- an HBox (myToolbar) with a button and a label
The buttons are used for adding, modifying and deleteing records of the
database. SO I was thinking of creating a custom event (myCustomEvent).
The code I have so far is following :
package events {
import flash.events.Event;
public class myCustomEvent extends Event {
public function SpellEvent(type:String) {
super(type);
}
override public function clone():Event{
var evt:myCustomEvent = new myCustomEvent(type);
return evt;
&nb sp; }
}
}
I was thinking of adding event listners to my buttons. For example my button to
add a new record will have a addRecordEventListener. In this listener I create
a new instance of myCustEvent and pass my new record as a parameter.
The same I will do with my button to delete a record.
My question is where and how I should make the difference between the 2
operations.
I suppose I have to create a new instance of my event and besides my new record
I also need to pass the type of operation : something like new
myCustomEvent(newRecord, "addRecord") or new myCustomEvent(newRecord,
"deleteRecord"). But in this case, how do I process the different operations?
I'm lost and hoping for a clear answer.
Thanks
