Oracle Forms Object Navigator

  1. File menu has options to create, open, save and print forms. This menu also includes an option to connect to the database and the Administration option that is used to compile forms and menu code. The last option on the File menu is the Exit option that will exit Oracle Forms Builder.
  2. Edit menu has options to cut, copy and paste objects, to invoke an editor and to undo an operation.
  3. View menu toggles the object navigator display between visual elements and ownership elements.
  4. The Layoutmenu has items that control objects on a form much in the way a drawing package does. Objects can be resized, moved, painted and otherwise manipulated using items on this menu.
  5. The Program menu has items that control form compilation, generation and execution (Run). Triggers, Procedures and other PL/SQL code can also be created from this menu. The Smart Triggers menu option displays the most commonly used triggers according to the type of object currently selected in the object navigator.
  6. The Debug menu has options for debugging forms as they are running. It includes menu items to establish break points and to step over the execution of code one line at a time.
  7. The Tools menu has options to switch between several different screens including the Layout editor, Menu editor and Object Navigator. There are also several wizards that can be launched from this menu including the Data Block wizard, the Layout wizard, and the LOV (List of Values) wizard.
  8. The Windows menu displays menu items for each of the windows you have open. By default, only one item – the Object Navigator – is displayed.

The content of the Object Navigator is broken down into 6 major sections:

  1. Forms(default 0)– (or data entry form) acts like a window into the database schema and Contains form objects and all of their sub-objects such as
    1. data blocks(two type one is used data block wozard whis is related to database another is build a nes data block(control block) is not related to database)
    2. triggers
    3. alerts
    4. canvases
    5. program units (procedures and functions)
    6. parameters
    7. windows
  2. Menus(default 0)– Contains menu objects and all of their sub-objects such as
    1. menu items
    2. parameters
    3. program units
  3. PL/SQL Libraries(default 0)– These are libraries of PL/SQL code (stored either in the database or in .plb files). Libraries can be shared among different forms and among different developers.
  4. Object Libraries(default 0)These are libraries containing a collection of objects (anything that can appear on a form).
  5. Built-in Packages(default 17 package)– Lists all of the packages (PL/SQL procedures) available by default to all forms, reports, etc.
  6. Database Objects(default 0)– Lists all of the database objects (Tables, Views, PL/SQL Libraries, and Stored Program Units) in the user’s Oracle database schema.

How to create a new block with in a form

Step-1

To create a new block, pull down the Tools menu ->select the Data Block wizard menu item Or select Block-> + -> check display this page next time ->next

Step-2

click on table or view /store procedure ->next

Step-3

Select table or view by browsing and select assential column ->next

Step-4

Select table or view by browsing and select assential column ->next

Step-5

Enter the block name ->next

Step-6

select the create data Block and call the layout wizard / just create data block ->finish

Step-7(to show table column on layout)

select column name ->finish

Step-8

select form/tabular ->next

Step-9

select frame title + Record Displayed+ distance between record + display scrollable ->finish

Canvas/layout editor

To view the actual form and its blocks and fields, pull down the Tools menu and select the Layout Editor menu item.

In the Layout Editor, fields and labels can be moved around by clicking and dragging. Other text, lines and boxes, etc. can be added using the tool palette on the left side of the window.

Some common operations on the Layout Editor on the left include:

  1. Button,Text,TextItem.....

Displaying Properties of the layout/canvas

While in the Layout Editor, double clicking on an object will bring up that object’s properties. Optionally, clicking on an object with the right mouse button will bring up a small menu which has the Properties menu item on it. The following figure shows the properties for the FNAME item.
