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 −

Step Description
1 Create a project with a name HelloWorld under a packagecom.tutorialspoint.client as explained in the Flex - Create Application chapter.
2 Modify HelloWorld.mxml as explained below. Keep rest of the files unchanged.
3 Compile 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, it will produce the following result: [ Try it online ]
