[flexcoders] FilterFunction

[valdhor]

You need to check into a number of things...

ArrayCollection:
http://livedocs.adobe.com/flex/3/langref/mx/collections/ArrayCollection.\
html
You need to know how to filter your data. Here you will find info
regarding FilterFunction.

CheckBox:
http://livedocs.adobe.com/flex/3/langref/mx/controls/CheckBox.html
This will show you some of the events that the checkbox generates
including the change event.

String: http://livedocs.adobe.com/flex/3/langref/String.html
This will show you a few ways of doing string searches including
indexOf().

As a quick and dirty example:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml";
layout="vertical"
     initialize="onInit()">
     <mx:Script>
         <![CDATA[
             import mx.collections.ArrayCollection;

             [Bindable] private var IPAddresses:ArrayCollection;

             private function onInit():void
             {
                 IPAddresses = new ArrayCollection([
                                     {IP:"192.168.1.1"},
                                     {IP:"192.168.1.2"},
                                     {IP:"192.168.1.3"},

                                     {IP:"192.168.2.3"},
                                     {IP:"192.168.2.4"},
                                     {IP:"192.168.2.5"}

             private function checkBoxChanged():void
             {
                 if(IPCheckBox.selected)
                 {
                     IPAddresses.filterFunction = IPFilter;
                 }
                 else
                 {
                     IPAddresses.filterFunction = null;
                 }
                 IPAddresses.refresh();

                     isMatch = true;
                 }
                 return isMatch;
             }
