Developing Application Dialogs Development of dialogs for use with the Tivoli SecureWay Application Management Toolkit relies on the Tivoli Application Extension Facility (AEF). AEF works with dialog descriptors, which are data structures that define dialog contents and behavior. Dialog descriptors are specified using the Dialog Specification Language (DSL), which is provided as part of AEF and ADE. Application dialogs written in DSL are platform independent; however, familiarity with graphical user interface (GUI) development using either X Windows or Microsoft Windows is helpful in understanding the terminology. For information about installing AEF and writing DSL, see Tivoli’s  TME 10 AEF Users Guide. Overview of AEF Dialogs As with any GUI windows application, the AEF dialogs must be managed. The relationship between thee dialogs is referred to as parent/child. The exception, of course, is that the top-level or  root window does not have a parent. The Application Management Toolkit dialogs run under the Tivoli desktop, which means any dialog you create with DSL will be a  child  of the Tivoli desktop. The hierarchy for the Application Management Toolkit dialogs is similar to the following example. C 103 Tivoli®  SecureWay Application Management Toolkit Guide
