Data services Data service objects let you interact with server-side data sources. You
can work with data sources that are accessible using SOAP-compliant
web services, Java objects, or HTTP GET or POST requests.
For more information, see Chapter 31, “Managing Data in Flex,” in
Developing Flex Applications .
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 33, “Validating Data in Flex,” in
Developing Flex Applications .
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 34, “Formatting Data,” in
Developing Flex Applications .
Cursor management Cursor management lets you control the cursor image within a Flex
application. You can use cursor management to provide visual
feedback to users to indicate when to wait for processing to complete,
to indicate allowable actions, or to provide other types of feedback.
For more information, see Chapter 24, “Using the Cursor Manager,” in
Developing Flex Applications .
History management History management lets users navigate through a Flex application
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 26, “Using the History Manager,” in
Developing Flex Applications .
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 22, “Using the Drag and Drop
Manager,” in
Developing Flex Applications .
ToolTips ToolTips let you provide helpful information to application users. When
a user moves their mouse over a graphical component, a toolTip pops
up and displays its text.
For more information, see Chapter 23, “Using ToolTips,” in
Developing
Flex Applications .
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 20, “Using Styles and Fonts,” in
Developing Flex Applications .
