Summary of Flex application features 31
Data services Data service objects let you interact with server-side data
sources. You can work with data sources that are accessible by
using SOAP-compliant web services, Java objects, or HTTP
GET or POST requests, and RemoteObjects accessed by using
the AMF protocol if you have the Flex Data Services.
For more information, see Chapter 39, “Storing Data,” in the
Flex 2 Developer’s Guide.
Data validation Data validators help you ensure that the values in the fields of a
data model meet certain criteria. For example, you can use a
validator to check whether a user entered a valid ZIP code value
in a TextInput control.
For more information, see Chapter 40, “Validating Data,” in the
Flex 2 Developer’s Guide.
Data formatting Data formatters let you format data into strings before displaying
it in the user interface. For example, you can use a formatter to
display a phone number in a specific format.
For more information, see Chapter 41, “Formatting Data,” in the
Flex 2 Developer’s Guide.
History management History management lets users navigate through a Flex
application by using the web browser’s Back and Forward
navigation commands. It also lets users return to the previous
location in an application if the browser accidentally navigates
away from that location.
For more information, see Chapter 32, “Using the History
Manager,” in the Flex 2 Developer’s Guide.
Drag-and-drop
management
Drag-and-drop management lets you move data from one place
in a Flex application to another. This feature is especially useful in
a visual application where your data can be items in a list, images,
or Flex components.
For more information, see Chapter 29, “Using the Drag and Drop
Manager,” in the Flex 2 Developer’s Guide.
Styles, fonts, and themes Styles, fonts, and themes help you define the overall appearance
of applications. You can use them to change the appearance of a
single component, or apply them across all components.
For more information, see Chapter 18, “Using Styles and
Themes,” in the Flex 2 Developer’s Guide.
Behaviors Behaviors let you add animation or sound to applications in
response to user or programmatic action.
For more information, see Chapter 17, “Using Behaviors,” in the
Flex 2 Developer’s Guide.
