Replace the Flex’s Default Right Click Menu

Adobe-Flex-CS3-48x48 Sometimes we need replace the Flex’s Default Right Click Menu,the code likes below that can hide the default menu but can not replace it(with function “hideBuiltInItems”).

var contextMenu : ContextMenu = new ContextMenu();

The code below tells you how to implement this.

1,add below javascript function at Flex’s Html file

function onNsRightClick(e){
if(e.which == 3){
return false;

function onIeRightClick(e){
if(event.button > 1){
  parent.frames.location.replace('javascript: parent.falseframe');
return false;

if(navigator.appName == "Netscape"){
document.addEventListener("mousedown", onNsRightClick, true);
2.modify Flex's MXMLI. add initialize method and MOUSEOVER event      <mx:Application xmlns:mx="" layout="absolute"  initialize="init()" mouseOver="getMouseTarget(event)" >

II. add MX Script

import mx.controls.Alert;
private var mouseTarget:DisplayObject;
function init()
ExternalInterface.addCallback("openRightClick", openRightClick);

function getMouseTarget(event:MouseEvent):void
   mouseTarget = DisplayObject(;

function openRightClick():void
var e:MouseEvent = new MouseEvent(MouseEvent.MOUSE_DOWN, true, false, mouseTarget.mouseX, mouseTarget.mouseY);

function showMouseEvent(event)
if(event.buttonDown == true)"Left");

<mx:Image x=”0″ y=”10″ id=”bbb” name=”bbb” source=”res/15.jpg” mouseDown=”showMouseEvent(event)” height=”247″/>

III.modify the parameter “wmode”(You can set the value opaque or transparent )

“src”, “playerProductInstall”,
“FlashVars”, “MMredirectURL=”+MMredirectURL+’&MMplayerType=’+MMPlayerType+’&MMdoctitle=’+MMdoctitle+”",
“width”, “100%”,
“height”, “100%”,
“align”, “middle”,
“id”, “FlexTest”, //// OBJECT ID
“wmode”, “opaque”, //////////////////////here
“quality”, “high”,
“bgcolor”, “#869ca7″,
“name”, “FlexTest”,
“type”, “application/x-shockwave-flash”,
“pluginspage”, “

That’s OK!


Sets the Window Mode property of the SWF file for transparency, layering, and positioning in the browser. Valid values of wmode are window, opaque, and transparent.

Set to window to play the SWF in its own rectangular window on a web page.

Set to opaque to hide everything on the page behind it.

Set to transparent so that the background of the HTML page shows through all transparent portions of the SWF file. This can slow animation performance.

To make sections of your SWF file transparent, you must set the alpha property to 0. To make your application’s background transparent, set the alpha

property on the <mx:Application> tag to 0.

The wmode property is not supported in all browsers and platforms.

    Nice article… very much helpful!.. thanks.

    Though some ppl might get this problemetic with IE7… for those, here’s some workout which I’ve found in some different article..

    Add event.stopPropagation() after parent.frames.location.replace(‘javascript: parent.falseframe’);

    Remember, in IE6 you SHOULD NOT call these new line of code, so essentially you just need a bit of detection to know how to invoke it.

    this solution works great for me on both ff and ie .. but the default scrolling in containers has stopped working.. it seems to be blocking the mousewheel event somehow.. if I remove the code for rightclick, mousewheel works just fine and im able to scroll.. has anyone run into this issue before? any thoughts appreciated..

    Something like this should work for IE7:

    function onIeRightClick(e){
    if(event.button > 1){
    parent.frames.location.replace(‘javascript: parent.falseframe’);
    event.cancelBubble = true;
    return false;

  11. malkomalko says:

    Whoops forgot the IE7 var declaration: Stick this above that function.

    // Browser Detection
    IE7 = (navigator.appVersion.indexOf(“MSIE 7.”)==-1) ? false : true;
