Flex TextInput Control Example

Let us follow the following steps to check usage of TextInput control in a Flex application by creating a test application:

1Create a project with a name HelloWorld under a package com.tutorialspoint.client as explained in the Flex - Create Application chapter.
2Modify HelloWorld.mxml as explained below. Keep rest of the files unchanged.
3Compile and run the application to make sure business logic is working as per the requirements.

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"
   width="100%" height="100%" minWidth="500" minHeight="500"
   <fx:Style source="/com/tutorialspoint/client/Style.css"/>   
   <s:BorderContainer width="550" height="400" id="mainContainer" 
      <s:VGroup width="100%" height="100%" gap="50" 
      horizontalAlign="center" verticalAlign="middle">
         <s:Label id="lblHeader" text="Form Controls Demonstration" 
         fontSize="40" color="0x777777" styleName="heading"/>
         <s:Panel id="textInputPanel" title="Using TextInput" 
            width="420" height="200" >
               <s:VerticalLayout  gap="10" 
                  verticalAlign="middle" horizontalAlign="center"/>	
            <s:TextInput text="Hello World" />
            <s:TextInput text="Hello World" enabled="false" />

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, this will produce following result: [ Try it online ]
