Oracle Forms Developer – Form Builder Reference, Volume 1

Primary Canvas property
Description
Specifies the canvas that is to be the window’s primary content view. At runtime, Form Builder always
attempts to display the primary view in the window. For example, when you display a window for the
first time during a session by executing the SHOW_WINDOW built-in procedure, Form Builder displays
the window with its primary content view.
If, however, Form Builder needs to display a different content view because of navigation to an item on
that view, the primary content view is superseded by the target view.
Applies to window

NULL
Required/Optional Required only for a window that will be shown programmatically, rather than in
response to navigation to an item on a canvas assigned to the window.
Primary Canvas restrictions
The specified view must be a content view (Canvas Type property set to Content), and must be assigned
to the indicated window (by setting the Window canvas property).
