Modal dialog windows often are used as interactive dialog boxes. When an application needs information from the end user before it can continue, you can display a modal dialog window to allow the end user to enter the required information. Most dialogs require the end user to either provide the necessary information or dismiss the dialog and cancel the operation.
File and Print dialogs are examples of interactive windows that—on most GUI platforms—are implemented as modal dialogs. Alerts and Lists of values (LOVs) are examples of specialized modal dialog windows that are native objects in Oracle Forms.
