Installing the sample files

Installing the sample files

I’ve created all the sample code for my upcoming book, tentatively titled Essential ActionScript 3.0, in Flex Builder 2, the new development tool from Adobe for authoring ActionScript and Flex applications. If you want to run the code examples in this article, you’ll need to install either Flex Builder 2 or the free Flex SDK. However, if you’re just curious to see the code, you can look at the class files in any text editor without installing Flex Builder 2.

Note: The examples are presented as-is, without detailed line-by-line explanations of how they work. However, points of interest are commented in the code.

To load the examples in Flex Builder 2, follow these steps:

  1. Extract Moock-eas3-imageviewer.zip to the folder of your choice.
  2. Open Flex Builder 2.0 and choose File > Import. This opens the Import dialog box.
  3. In the Select an import source pop-up menu, choose Existing Projects into Workspace.
  4. For Select root directory, select the folder you chose in Step 1.
  5. Click Finish.

To run the demo applications, follow these steps:

  1. In the Flex Builder 2 Navigator panel, under the ImageViewerDemos project, select the file you want to run (Take1PortDemo.as, Take1RewriteDemo.as, Take2Demo.as, Take3Demo.as, or Take4Demo.as).
  2. Click the Run toolbar button (the white arrow in the green circle).
