Flex TitleWindow: Add buttons to Title

My question is Related to http://www.experts-exchange.com/Web_Development/Web_Languages-Standards/Flex/Q_24513126.html

I've been trying to implement a help button in the title of a TitleWindow and have followed this thread without "real" success. My button is created as a single (blue) sprite and appears at TitleWindow.x=0 & TitleWindow.y=0 coordinates.

I want to position my button within the title on the far right, in the same position as the close button would appear if it were turned on.

Attached is my extended TitleWindow class and a screen shot of my TitleWindow. As the related solution didn't have a post of the final workng code I was wondering if you might be able to help by looking at my implementation of the same?
package com.anz.cola.custom.actionscript
{
        import com.anz.cola.custom.ANZButton;
        import com.anz.cola.utils.Omniture;
        
        import flash.events.MouseEvent;
        import flash.external.ExternalInterface;
        
        import mx.containers.TitleWindow;
        import mx.controls.Alert;
        
        public class ANZTitleWindow extends TitleWindow
        {
                public function ANZTitleWindow()
                {
                        super();
                }
                
                override protected function createChildren():void {
                        super.createChildren();
                        
                        var helpButton:ANZButton = new ANZButton();
                        helpButton.label = "Help";
                        helpButton.useHandCursor = true;
                        helpButton.visible = true;
                        helpButton.includeInLayout = true;
                        
                        helpButton.addEventListener(MouseEvent.CLICK, loadHelp);
                        titleBar.addChild(helpButton);
                        
                }
 
                private function loadHelp(event:MouseEvent):void {      
                        var javascriptFunction:String = "loadHelpPage"; 
                        
                        if (ExternalInterface.available) {
                                ExternalInterface.call(javascriptFunction, "SaveConfirmationPopup");
                                var omniture:Omniture = new Omniture();
                                //send Omniture button HELP button Click event
                                omniture.omnitureTrackButtonClick("creditcard:ola:HelpButton_SaveConfirmationPopup");
                        } else {
                                Alert.show(javascriptFunction + " is not available");
                        }       
        
                }
 
        }
}

Well, the most simple app I could write works fine for me:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical" 
	verticalAlign="middle" xmlns:local="*" creationComplete="init()" viewSourceURL="srcview/index.html" xmlns:demo="demo.*">
	<demo:CustomTitleWindow title="My window title" id="titleWindow"
		width="600" height="500" showCloseButton="true">
	</demo:CustomTitleWindow>
</mx:Application>
 
with 
 
 
<?xml version="1.0" encoding="utf-8"?>
<mx:TitleWindow xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical" >
	<mx:Script>
		<![CDATA[
			import mx.controls.Button;
		
            override protected function createChildren():void {
                    super.createChildren();
                    
                    var helpButton:Button = new Button();
                    helpButton.x = this.width - 100;
                    helpButton.y = 5;
                    helpButton.width = 100;
                    helpButton.height = 20;
                    helpButton.label = "Help";
                    helpButton.useHandCursor = true;
                    helpButton.visible = true;
                    helpButton.includeInLayout = true;
                    
                    titleBar.addChild(helpButton);
            }

Try this:

var helpButton:ANZButton = new ANZButton();
helpButton.x = this.width - 100;     // <<<<<<<< Added
helpButton.y = 5;                            // <<<<<<<< Added
helpButton.width = 100;                // <<<<<<<< Added
helpButton.height = 20;                // <<<<<<<< Added
helpButton.label = "Help";

zzynx,
Thanks you got me pointed in the right direction, my button now appears at the correct size however it still floats outside the upperLeft corner of the titleBar. All attempts to position relative to the titleWindow or titleBar x/y, widths etc have just skipped the button from outside left to outside right of the titleWindows borders. But I can't follow exactly how or why it's doing it. I've set watches and interrogated any number of properties with limited success in finding my answer.

Although I've messed around with any number of alternatives over the couple of hours, the only way I've been able to get the button to appear inside the titleBar is to explicitly set  it's xPos as follows:  

helpButton.x = this.titleTextField.width + 430;

Though this works it's kind of ugly, particularly if I wanted to dynamically add the titleText. A change in the titleText value length would impact the button position.  Certainly less than idel.

I was hoping to find a cleaner solution...any further thoughts would be grately appreciated.

Cheers
Mark

zzynx,

Right you are, your simple code works a treat. Unfortunately I'm not writing my applicaiton in native Flex, I'm using Flex as a Wrapper for the Adobe FormGuide Designer ES.....not by choice I might add. All the code I'm writing in Flex are actually hacks on inadequacies of the FormGuide....and believe me there are MANY!!!

This would appear to be yet another time where the parent application (IE: the FormGuide) is making life hell for me and confusing itself as the parent rather than the titleWindow of my Button. I have seen this behaviour before unfortunately. An all though I can see the source code of the FormGuide I can't edit it as is rebuilt each time I comile the Form....GRRRRRR!

Your answer is spot on so I shall reward you the points....you got me to where I needed to be....I'll have to do some more hacky stuff to make this work exactly how I want. I know how far I want the intent to be from the right border so for now I'm going to settle for :
override protected function createChildren():void {
    super.createChildren();
 
    var helpButton:Button = new Button();
    var xPos:int = (this.width - this.titleTextField.width) - 110;
    helpButton.x = this.titleTextField.width + xPos;
    helpButton.y = 5;
    helpButton.width = 100;
    helpButton.height = 20;
    helpButton.label = "Help";
    helpButton.useHandCursor = true;
    helpButton.visible = true;
    helpButton.includeInLayout = true;
 
    titleBar.addChild(helpButton);
}
