Flex ToggleButton Control Example

Let us follow the following steps to check usage of ToggleButton 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" />
   <fx:Script>
      <![CDATA[
         import mx.controls.Alert;
         import mx.events.FlexEvent;

         protected function button_clickHandler(event:MouseEvent):void {
            Alert.show("Hello World!");				
         }
      ]]>
   </fx:Script>
   
   <s:BorderContainer width = "550" height = "400" id = "mainContainer" 
      styleName = "container">
      <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 = "toggleButtonPanel" title = "Using ToggleButton" 
            width = "420" height = "200">		
            <s:layout>
               <s:HorizontalLayout  gap = "10" verticalAlign = "middle" 
                  horizontalAlign = "center" />	
            </s:layout>
            
            <s:ToggleButton id = "clickMeToggleButton" label = "Click Me" 
               click = "button_clickHandler(event)" />
            <s:ToggleButton id = "disabledToggleButton" label = "Disabled Button" 
               enabled = "false" />					
         </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 ]
