Flex Label Control Example

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

StepDescription
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"
   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"/>
   <s:BorderContainer width="550" height="500" id="mainContainer" 
   styleName="container">
      <s:VGroup width="100%" height="100%" gap="50" horizontalAlign="center"
      verticalAlign="middle">
         <s:Label id="lblHeader" text="Basic Controls Demonstration" 
         fontSize="40" color="0x777777" styleName="heading"/>
         <s:Panel title="Using Label" width="420" height="100" >
            <s:layout>
               <s:VerticalLayout paddingTop="10" paddingLeft="10"/>
            </s:layout>				
            <s:Label text = "This is a label"  paddingTop="6" />
            <s:Label text = "This is a highligted label." 
            fontWeight="bold" backgroundColor="0xFFF200" paddingTop="6"/>
         </s:Panel>		
      </s:VGroup>	 
   </s:BorderContainer>	
</s:Application>

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 ]
