Each application panel you create serves a specific purpose, with unique fields, messages, and help information defined for each one. This topic explains how to define elements that are common among application panels. This includes defining the application panels, and the interactive elements of panels, including action bars, instruction text, and command areas. We also tell you how to arrange the contents of your application panels using panel regions and dividers.

The PANDEF tag allows you to define in one place common attributes and values for the panels in your application—see Defining panel defaults.
