SELECTOR
Guide Section: An EASAP GUI
EASAP Tree: USER INTERFACE → FORM LIST or TABBED PANE LIST → FORM or TABBED PANE
SELECTOR is a GUI object that allows a User to create and customize a list of items in a table. Below the table are the input objects and modifying buttons: 'Add', 'Update' and 'Delete'. The choices in the list are called USER ITEM's, their types are derived from Child objects to DEFAULT ITEM itself a Child of SELECTOR. The items in the list may be object references and can be referenced by other objects in the EASAP.
