FLEX 3 Custom Event Listener with Popup window
Create the custom Event.
In this case I will need to pass an object along with the event.
Save the actionscript as ParseFixClickEvent.as
package modules.FIXParser.Events
{
import flash.events.Event;
public class ParseFixClickEvent extends Event
{
public var params:Object;
public static const PARSE:String = “parseEvent”;
public function ParseFixClickEvent(params:Object, type:String )
{
super(type);
this.params = params;
}
public override function clone():Event {
return new ParseFixClickEvent(params,type);
}
public override function toString():String
{
return formatToString(”ParseFixClickEvent”,”type”);
}
}
}
In my case I have a datagrid, where if I click an item in column 3, I fire an event that creates a popup window.
Here it is:
private function itemClickEvent( event:ListEvent ):void
{
//loglink.visible = “true”;
//details.visible = “true”;
if (event.columnIndex == 2) {
logdir = event.itemRenderer.data.rmi_ip;
logserver = event.itemRenderer.data.Cluster_Name;
var parseWindow:ParseFixForm = ParseFixForm(PopUpManager.createPopUp(this, ParseFixForm, true));
parseWindow.addEventListener(modules.FIXParser.Events.ParseFixClickEvent.PARSE,doParse);
parseWindow.mylogdir = logdir;
parseWindow.myserver = logserver;
parseWindow.target = event.itemRenderer.data.CounterpartyCompID;
parseWindow.sender = event.itemRenderer.data.CompID;
CurrentDestination = event.itemRenderer.data.DestinationName;
}
When the event is fired from the popup, doParse is called.
public function doParse(e:ParseFixClickEvent):void {
var Parser:FIXParser = new FIXParser;Parser.FixParameters = e.params;Parser.label = CurrentDestination;TN.addChild(Parser);TN.selectedIndex = TN.numChildren - 1;
}
