4.13. Where we will go from here

The container classes supplied by the Flex framework provide a great starting point. Many GUI toolkits don't even have basic containment systems such as the HBox or VBox. But the Flex framework still leaves a lot of room for new types of containers like the ones I've demonstrated in this chapter. With these tools in hand, building applications that show large amounts of data, or include all resizing and reordering elements, or need expanding and collapsing segments, are just a drop-in component away.

Using the right containers and layout is critical to building a user interface that scales and skins well. These new containers give you a lot of layout tools to go in your tool bag. In the next chapter, we upgrade the basic control types.
