Writing a Flash Widget

Exposing Methods

You can expose any method in your Flash file to be accessible by external programs using the ExternalInterface method in AS3.0 or public methods in AS2.0. For AS2.0 Flash files, you can expose your methods to Appspace by creating a public method as below:

public function Update(name:String, address:String) : void

For AS3.0 Flash files, add the following code to your initialization method:

if (ExternalInterface.available == true)
{ExternalInterface.addCallback("DoUpdate", Update);}

The format of the ExternalInterface method is as follows:

ExternalInterface.addCallback("{Method Name}", {Internal public function})
  • Method Name – The name of the method external programs will call.
  • Internal public function – Reference to the function in the Flash file that will be executed.

Using FlashVars

Another option to communicate with your Flash file is via FlashVars. This is the common method used to initialize a Flash file with start up parameters when embedded inside a web page. To use FlashVars with Appspace, you must place your FlashVars initialization code in the main method of your Flash file. DO NOT place your FlashVars as static properties in the Flash file. As an example, lets assume your FlashVars are ip= and f=60. The following demonstrates how you would initialize these values:

public class Main extends Sprite
private var _ip:String;
private var _f:Number;
public function Main() : void {
_ip = this.root.loaderInfo.parameters["ip"];
_f = this.root.loaderInfo.parameters["f"];

Using the Flash Container Widget

The following tasks are done via the XML editor in the Visual Editor. Under the advanced channel’s Edit tab, select any layout in your advanced channel and click on the Visual Editor link. In the Visual Editor window, select the XML tab.

Setting FlashVars on your Widget

FlashVars are key value pairs that you can pass to configure a Flash file during its initialization method. To set the FlashVars in your custom Flash file follow these steps:

Locate your Flash Container element in the XML editor.

<Name>Flash Container</Name>

Under the <Properties> tag, add a collection of key value pairs corresponding to your FlashVars. The format is as follows:


For example, if your FlashVars are: ip= and f=60 You would add the following key value pairs:


Calling Methods on the Flash Container Widget

Actions on a Flash widget can be called via events on Action Script.

../../../../../../_images/01d13.pngSelect the widget that will trigger the function call on the Flash Container. Click on the Action command in the Flash Container’s Properties page. Create an action for the Mouse Click/Touch event. Save the changes by clicking on the Apply button.

In the app XML editing tab in the Visual Editor, locate the Trigger XML for your Flash Container widget. The format of the Trigger XML is as follows:


Based on the example earlier, we exposed a method called DoUpdate that takes 2 parameters name and address. The XML to call the method would be:
