About Object Navigator views
The Object Navigator can display modules in one of two views: Ownership (the default), and Visual. The view determines which objects you see in the Object Navigator and how those objects are arranged.
- Ownership View
-
- In the ownership view, all form objects are
visible, and the display hierarchy corresponds to the Oracle Forms object
ownership hierarchy: formblockitem. Items and relations are owned
by blocks; blocks are owned by forms; triggers can be owned by forms, blocks,
or items; all other form objects (windows, editors, record groups, etc.) are
owned by forms.
-
- Visual View
-
- In the Visual view, only windows, canvases, and items are displayed. The
Visual view hierarchy corresponds to the hierarchy of objects in a form window:
windowcanvasitem. Items are assigned to canvases; canvases are
assigned to windows. Each window can have multiple canvases, and there can
be multiple items on a single canvas.
When the Object Navigator is in Ownership view, form items are listed under
the blocks to which they are assigned. When the Object Navigator is in Visual
View, form items are listed under the canvases on which they are displayed.
When a form contains items that are not assigned to any canvas (because their
item Canvas property is set to <Null>), those items are displayed under
the Null Canvas node. When there are canvases that are not yet assigned to
a window, they are displayed under the Null Window node.

- Only Objects with PL/SQL Option
-
- You can set the View | Show PL/SQL only menu
option On or Off. By default, this option is Off, and all objects are visible.
Setting Only Objects with PL/SQL On hides all objects except code objects
(triggers, program units, etc.) and objects to which triggers can be attached
(forms, block, items).
