PopUpButton control in Flex4:

The PopUpButton control is a MX component. It has no Spark component.
It contains a two horizontal button: main button and a small button or pop-up button. Pop-up button has a icon and main button is a button control. When the user clicked a small button then opens a second pop-up control. If you click outside the pop-up control the pop-up will be closed. You can use the menu control as a pop-up control. It is not necessary that you can use a menu control as a pop-up control. You can change the label of the button using change function. You can use any component as a pop-up control. The tag of this control is <mx:PopUpButton>.

Example:

 <?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"

minWidth="955" minHeight="600">

<fx:Script>

<![CDATA[

import mx.controls.*;

import mx.events.*;

private var menu1:Menu;

private function menuinit():void {

menu1 = new Menu();

var data:Object = [

{label: "Open"},

{label: "Edit"},

{label: "Save"},

{label: "Save as"},

{label: "Cut"},

{label: "Copy"}

];

menu1.dataProvider = data;

menu1.addEventListener("itemClick", changeHandler);

pbtn.popUp = menu1;

}

private function changeHandler(event:MenuEvent):void {

var label:String = event.label;

pbtn.label = label;

lbl.text= label + " " + "Successfully";

}

]]>

</fx:Script>

<s:Panel title="PopUpButton Control Example" width="199" height="263"/>
