Join David Gassner for an in-depth discussion in this video Handling navigation between views, part of Flash Builder 4.5 and Flex 4.5 New Features.
In a mobile device application, navigation is handled by shifting from one view to another.…The views are considered to be in a stack to which you can add views and subtract them.…When you add a view, it's called pushing a view and when you remove you…it's called popping.…I'll demonstrate this in this version of the application which you can import…from the Exercise Files as ViewNavigation.fxp.…If you see the Run Configurations dialog box pop-up, set the Launch method to…Desktop, choose a device to stimulate, and then click Run.…
In this version of the application I've added a bitmap image to the Home view.…It's scaled and placed on the screen and I'm going to create a secondary view and…then a button on the Home view that will navigate to it.…So I'll close the application and return to Flash Builder.…I'll go into Design ciew and then I'll drag in a button and toss it on top of the ciew.…Don't worry too much about where it's placed.…We'll set that in code.…Then I'll go to Source view and I'll set the following properties.…

Q: Is Flash Builder compatible with Mac OS X 10.7 (Lion)?
Q: I'm using the most recent versions of Flash Builder and Flex. The projects provided in this course's exercise files don't run correctly. How do I get the code working?
A: The course's exercise files were built for the original release of Flash Builder and Flex 4.5. There are two potential issues: the version of the Flex SDK linked into each project and the version of Flash Player you have installed on your system.
For each project, follow these steps after importing it into Flash Builder:
- In the Package Explorer view, right-click on the project name and choose Properties.
- Click Flex Compiler.
- Change the Flex SDK Version to Use default SDK.
- Click OK.
- The project should now compile correctly.
- Open Windows Explorer (Windows) or Finder (Mac).
- Navigate to the Flash Player installation folder.
- Open the player subfolder.
- Open the subfolder for your operating system (Mac or Windows).
- Open the version subfolder.
- If running on Mac, open the DMG file and install the Flash Player application.
- If running on Windows, run the Flash Player installer executable for whichever browser you use for previewing Flex applications.
