Full screen mode in flash/flex applications

One of the cool feature of the latest update of flash player9 is the support of full screen mode. To view the applications in the full screen you need the flash player version 9,0,28,0 or greater. Get the latest flash player here.

Note :
During the full screen mode most of the keyboard controls are disabled. Only the keys for exiting the mode will work. So you can't keyin the text during the fullscreen mode. The mouse events are allowed in this mode.

To create the flash/flex applications to support full screen do the following

1. Download and install the latest version of flash player
2. Download the sample files which is zipped. The archive contains two important files playerglobal.swc and a playerglobal.abc
3. Flash 9 :
Copy playerglobal.abc from the ZIP file and replace the older version in your Flash installation here:
Flash 9 Public Alpha/en/Configuration/ActionScript 3.0/playerglobal.abc

Flex 2.0: Copy playerglobal.swc from the ZIP file and replace the older version in your Flex SDK
Flex Builder 2/Flex SDK 2/frameworks/libs/playerglobal.swc

4. Use the following As2.0 and AS3.0 in your application on any mouse event. This ActionScript that initiates full-screen mode can be called only in response to a mouse click or keypress. If it is called in other situations, it will be ignored (in ActionScript 2.0) or throw an exception (in ActionScript 3.0).

Flash 9:

Stage["displayState"] = "fullScreen"; //fullscreen mode
Stage["displayState"] = "normal"; //normal mode

Flex 2.0:

import flash.display.Stage;
import flash.display.StageDisplayState;
import flash.display.InteractiveObject.*;

      //Go to Full screen mode
 private function goFullScreen():void
{
stage.displayState = StageDisplayState.FULL_SCREEN;
}   
//return back to normal mode
private function backToNormal():void
 {
    stage.displayState = StageDisplayState.NORMAL;
 }

5. And finally to make the full screen mode work,you need to add a
new parameter to the OBJECT and EMBED tags in your HTML. 

In param tag: name="allowFullScreen" value="true"
In embed tag: allowFullScreen="true"
