About Flex Builder perspectives 41
Content Assist also provides hinting for any custom MXML components or ActionScript
classes that you create yourself and which are part of your project. For example, if you define a
custom MXML component and add it to your project, code hints are displayed when you
refer to the component in your MXML application.
Designing Flex applications in Flex Builder
The development perspective has two modes: one for writing code and the other for visually
laying out your application. You can switch between the two modes by selecting either the
Code or Design buttons from the code editor toolbar. When you switch into Design mode,
the development perspective displays the design canvas and the supporting Components and
Flex Properties views.
Design canvas While in the code editor, you can switch into Design mode and then drag
containers and components onto the design canvas, size and move containers and
components, and otherwise visually interact with your Flex application.
NOTE
Design mode is not available when working with ActionScript applications. To preview
your ActionScript applications, you need to build and run them. For more information,
see Chapter 10, “Building Projects” and Chapter 11, “Running and Debugging
Applications” in Using Flex Builder 2.
