Flex TitleWindow Example

Let us follow the following steps to check usage of TitleWindow in a Flex application by creating a test application −

Step 1 – Create a Project

Create a project with a name HelloWorld under a package com.tutorialspoint.client as explained in the Flex - Create Application chapter.

Step 2 – Create a custom Title WIndow component

Launch Create MXML Component wizard using the option File > New > MXML Component

. Flex New Component Wizard

Enter Package as com.tutorialspoint.client, name as CustomTitleWindow and choose based on as existing flex TitleWindow control spark.component.TitleWindow. Modified it as mentioned below.

Following is the content of the modified mxml file src/com.tutorialspoint.client/CustomTitleWindow.mxml.

<?xml version = "1.0" encoding = "utf-8"?>
<s:TitleWindow xmlns:fx = "http://ns.adobe.com/mxml/2009" 
   xmlns:s = "library://ns.adobe.com/flex/spark" 
   xmlns:mx = "library://ns.adobe.com/flex/mx" width = "400" height = "300"
   title = "Title Window Container" close = "PopUpManager.removePopUp(this);"> 
      <s:VerticalLayout verticalAlign = "middle" horizontalAlign = "center" />
         import mx.managers.PopUpManager;
   <s:Label text = "Content area of title window" />

Step 3 – Modify HelloWorld.mxml

Modify HelloWorld.mxml as explained below. Keep rest of the files unchanged.

Following is the content of the modified mxml file src/com.tutorialspoint/HelloWorld.mxml.

<?xml version = "1.0" encoding = "utf-8"?>
<s:Application xmlns:fx = "http://ns.adobe.com/mxml/2009"
   xmlns:s = "library://ns.adobe.com/flex/spark"
   xmlns:mx = "library://ns.adobe.com/flex/mx
   width = "100%" height = "100%" minWidth = "500" minHeight = "500">  
   <fx:Style source = "/com/tutorialspoint/client/Style.css" />
         import mx.core.IFlexDisplayObject;
         import mx.managers.PopUpManager;
         private function showWindow():void {
            var popUp:IFlexDisplayObject = 
   <s:BorderContainer width = "630" height = "480" id = "mainContainer" 
      styleName = "container">
      <s:VGroup width = "100%" height = "100%" gap = "50" 
         horizontalAlign = "center" verticalAlign = "middle">
         <s:Label id = "lblHeader" text = "Layout Panels Demonstration" 
            fontSize = "40" color = "0x777777" styleName = "heading" />
         <s:Panel id = "titleWindowPanel" title = "Using TitleWindow" 
            width = "500" height = "300">
               <s:VerticalLayout  gap = "10" verticalAlign = "middle" 
                  horizontalAlign = "center" />	
            <s:Button id = "showButton" 
               label = "Click to show the TitleWindow container" 
               click = "showWindow();" />

Step 4 – Complie and Run application

Compile and run the application to make sure business logic is working as per the requirements.

Once you are ready with all the changes done, let us compile and run the application in normal mode as we did in Flex - Create Application chapter. If everything is fine with your application, it will produce the following result: [ Try it online ]
