The CheckBox control of Flex is a very common GUI, which is supported by almost every computer language. CheckBox control is used when we need to have a set of true or false values.
We can add a text label at left, right, top, bottom of a CheckBox. Flex automatically adjusts the label of the CheckBox control to fit in the component.
The default state of the CheckBox is unchecked, we can change the state of a CheckBox by selecting a particular CheckBox item.
<mx:CheckBox> tag is use to access this control. Like any other control we can specify an id to it for accessing from any other part of the file or from the ActionScript file.
Flex Checkbox Control Example:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Panel title="Example of CheckBox" horizontalCenter="10" verticalCenter="16" width="200" height="200">
<mx:VBox height="100%" width="100%">
<mx:CheckBox id="adobe" label="Adobe" click="chkValDisp()"/>
<mx:CheckBox id="sun" label="Sun" click="chkValDisp()" />
<mx:CheckBox id="mozilla" label="mozilla" click="chkValDisp()"/>
<mx:TextArea id="disp" height="75" width="100%"/>
</mx:VBox>
</mx:Panel>
<mx:Script>
<![CDATA[
import mx.events.ItemClickEvent;
public function chkValDisp():void{
disp.text="";
if(adobe.selected==true){
disp.text+="Flex"+"\n";
}
if(sun.selected==true){
