Editor to share with you how to build and run Flex applications, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's learn about it!

Build and run Flex applications

Flex is an architecture that provides development, design and operational support, which enables developers to create and utilize Adobe?

Flash?Player9 serves as the "rich client Internet application / richInternetapplications/RIA" in the foreground to meet users' more intuitive and interactive online experience.

Typical steps for developing a Flex application are as follows:

1. Select a series of pre-customized components (such as tables, buttons, etc.) that are used to design the application interface

two。 Lay out components to design the user interface.

3. Use styles and themes to enhance visual design.

4. Add dynamic behavior (such as interactions between program components).

5. Define and connect the required database services.

6. Compile the source code into a SWF file and run it in FlashPlayer.

How Flex applications are compiled and released:

All elements are compiled or linked to your Flex application. The Flex application is compiled into a SWF file and then run under FlashPlayer. When a source code is compiled, it is converted to an ActionScript class and incorporated into an SWF file with graphics and other resources. This is one of the essence of Flex. At run time, SWF files interact with the required external libraries, services, and data sources.

General Flex applications do not need the support provided on the server side. Therefore, you can compile them on your local computer and publish them to your users in the HTML page of the Web service.

Of course, you can also combine Flex with Adobe?FlexDataServices2, ColdFusionFlashRemotingService, or other Java and J2EEService server technologies to carry out the network application program of Bax S structure.

The development of preface.

◆ MXML: where it all started

You can use the components provided by Flex to define the user interface in MXML. Here is an example of the main MXML program file:

If you are already familiar with XML, you can recognize the format of this example at a glance. The first two lines of the MXML code contain the version number, code, and namespace information, and the body of the document contains the details of the program.

All the details of the Flex application are placed in tag pairs. At the same time, you can also nest other child tag pairs in the parent tag pair.

This example creates a simple program that displays "SayhellotoFlex!" on the screen. The words. In this program, the TextArea and Button components are declared and their corresponding text and label properties are set.

Note: each tag in the MXML file has the prefix mx, which is the design namespace for Flex.
