- Oracle Form Builder is a component of Oracle Developer/2000 that is used to create event-driven applications to enter, access, change, or delete data from an Oracle database. - A Forms application consists of forms, menus, and libraries. Forms uses triggers, processes, and events to control user interactions and database transactions. - The main components of a Forms application include windows, canvases, blocks, items, triggers, alerts, lists of values (LOVs), editors, parameters, program units, libraries, and object groups.

12. The Forms Application Form Builder builds Forms, Menus and Libraries Application consists of at least one Form Can also include one or more Menu and Library modules Oracle provides default Menu

14. The Forms Application What You See exit enter File Edit View Query Block Record Insert Help Whatever Are you really sure you want to do this? Canvas View Control Item Base-Table Item Menu Window Yes No

16. Forms Components Highest Level of Hierarchy - Forms - Menu - Built-in Packages - Database Objects

17. Forms Components Windows - Displays canvases. - Form can have multiple windows. - Modal; user must respond and dismiss window before doing anything in another window. - Modeless; user can move to another window.

18. Forms Components Canvas-Views - Visual element of Forms. This is how you display all those Items. - Canvas; Background on which text and items are placed. - View; Visible portion of canvas. - Form can have multiple canvases. - Canvases can be stacked, scrolled.

19. Forms Components Blocks - Base-Table Block corresponds to Database Table; set of items representing database table columns. An ‘instance’ of a Base-Table Block corresponds to a Database Record. - Control Block is usually a collection of control items (e.g. Buttons, Check-Boxes, Radio Groups), but can also be collection of Display Items (read-only text), Text Items (‘variables’), images, etc.

20. Forms Components Block Properties

21. Forms Components Items - Base-Table Items are text items that correspond to Database Columns. Forms creates them automatically. - Control Items can be Buttons, Check-Boxes, Radio Groups, Display Items (read-only text), Text Items (‘variables’), images, etc.

22. Forms Components Item Properties

23. Forms Components Visual Attributes - Collection of display properties. - Refer to Named Visual Attribute in Items to standardise appearance. Change in NVA will affect all Items referring to it. Property Classes - Collection of ANY properties. - When items refer to Property Class, only properties that make sense for that item will be used.

24. Forms Components Triggers - At Form, Block or Item level - Lower level triggers fire before higher level triggers - If same trigger-type occurs at different levels, only lowest will fire

26. Forms Component Alerts - Window that displays message - Modal; User must respond - One, two or three buttons - Three types; - Stop (stop sign) - Caution (exclamation) - Information ( ‘i’ symbol) - Use SHOW_ALERT built-in function

27. Forms Components LOVs - Allows user to select from specific set of values. - Displays Record Group.

28. Forms Components Editors - Editor; simple text-editor dialog box for entering lines of text into Text Item. - Can create editors with different appearances for different text fields.

29. Forms Components Parameters - Used as a Form variable. - Pass values between Forms.

30. Forms Components Program Units - PL/SQL Procedures and Functions used in this Form.

31. Forms Components Attached Libraries, Libraries & Built-in Packages - PL/SQL procedures and functions. - Attached Library; Reference collected routines. - Library; Maintain and reference collected routines. - Built-in Packages; Oracle supplied procedure and functions.

32. Forms Components Object Groups - Package reusable objects for later copying or reference. - E.g. Your Form includes an alarm clock to wake the user after ten minutes inactivity. This includes Triggers, Procedures, a Window, some graphics, etc. You can package these objects together to conveniently include this functionality in other forms.
