Figure 20.1 The Interface Builder
Because the Interface Builder generates source code which uses the CAPI library, this chapter assumes at least a minimum knowledge of the CAPI. See the CAPI User Guide and Reference Manual for details.
A complete example showing you how to use the Interface Builder to design an interface, and how to integrate the design with your own code, is given in Example: Using The Interface Builder. You are strongly advised to work through this example after reading this chapter, or in conjunction with it.
