XML namespaces give you the ability to use classes in custom packages that are not in the Flex namespaces. The

following example shows an application that contains a custom component called CustomBox. The namespace value

myComponents.boxes.* indicates that an MXML component called CustomBox is in the myComponents/boxes

directory.

<?xml version="1.0"?>

<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"

xmlns:mx="library://ns.adobe.com/flex/mx"

xmlns:s="library://ns.adobe.com/flex/spark"

xmlns:MyComps="myComponents.boxes.*">

<s:Panel title="My Application"

height="150">

<MyComps:CustomBox/>

</s:Panel>

</s:Application>

The myComponents/boxes directory can be a subdirectory of the directory that contains the application file, or it can

be a subdirectory of one of the ActionScript source path directories assigned in the flex-config.xml file. If copies of the

same file exist in both places, Flex uses the file in the application file directory. The prefix name is arbitrary, but it must

be used as declared.

When using a component contained in a SWC file, the package name and the namespace must match, even though

the SWC file is in the same directory as the MXML file that uses it. A SWC file is an archive file for Flex components.

SWC files make it easy to exchange components among Flex developers. You exchange only a single file, rather than

the MXML or ActionScript files and images, along with other resource files. Also, the SWF file inside a SWC file is

compiled, which means that the source code is obfuscated from casual view.

For more information on SWC files, see “Flex compilers” on page 2164.

Using MXML to trigger run-time code

Flex applications are driven by run-time events, such as when a user selects a Button control. You can specify event

listeners, which consist of code for handling run-time events, in the event properties of MXML tags. For example, the

<s:Button> tag has a click event property in which you can specify ActionScript code that executes when the Button

control is clicked at run time. You can specify simple event listener code directly in event properties. To use more

complex code, you can specify the name of an ActionScript function defined in an

<fx:Script> tag.

The following example shows an application that contains a Button control and a TextArea control. The click

property of the Button control contains a simple event listener that sets the value of the TextArea control’s

text

property to the text

Hello World.

<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"

<s:Panel title="My Application">

<s:VGroup left="10" right="10" top="10" bottom="10">

<s:Label text="Enter Text:"/>

<s:TextInput id="textinput1"

text="Hello"/>

<s:Label text="Bind Text to the TextArea control:"/>

<s:TextArea id="textarea1"

text="{textinput1.text}"/>

<s:Button label="Submit"

click="textinput1.text='Goodbye';"/>

</s:VGroup>

</s:Panel>

</s:Application>

As an alternative to the curly braces ({ }) syntax, you can use the <fx:Binding> tag, in which you specify the source

and destination of a binding. For more information about data binding, see

“Data binding” on page 299.

Using RPC services

Remote-procedure-call (RPC) services let your application interact with remote servers to provide data to your

applications, or for your application to send data to a server.

Flex is designed to interact with several types of RPC services that provide access to local and remote server-side logic.

For example, a Flex application can connect to a web service that uses the Simple Object Access Protocol (SOAP), a

Java object residing on the same application server as Flex using AMF, or an HTTP URL that returns XML.

The MXML components that provide data access are called RPC components. MXML includes the following types of

RPC components:

• WebService provides access to SOAP-based web services.

• HTTPService provides access to HTTP URLs that return data.

• RemoteObject provides access to Java objects using the AMF protocol (Adobe LiveCycle Data Services ES only).

In MXML, define the RPC components in an <fx:Declarations> tag. You use the <fx:Declarations> tag to

declare non-visual components an MXML file.

The following example shows an application that calls a web service that provides weather information, and displays

the current temperature for a given ZIP code. The application binds the ZIP code that a user enters in a TextInput

control to a web service input parameter. It binds the current temperature value contained in the web service result to

a TextArea control.

<s:Label text="Location:"/>

text="{WeatherService.GetWeather.lastResult.CurrentTemp}"/>

Storing data in a data model

You can use a data model to store application-specific data. A data model is an ActionScript object that provides

properties for storing data, and optionally contains methods for additional functionality. Data models provide a way

to store data in the Flex application before it is sent to the server, or to store data sent from the server before using it

in the application.

You can declare a simple data model that does not require methods in an <fx:Model>, <fx:XML>, or <fx:XMLList>

tag. In MXML, define a data model in an

<fx:Declarations> tag. You use the <fx:Declarations> tag to declare

non-visual components an MXML file.

The following example shows an application that contains TextInput controls for entering personal contact

information and a data model, represented by the

<fx:Model> tag, for storing the contact information:
