When a content canvas is displayed in a window—in response
to navigation or programmatic control—it becomes the window's current content
canvas. Unless it is replaced by another content canvas, it remains the current
content canvas for the duration of the runtime session (even if the end user
closes or iconifies the window).
When multiple content canvases are assigned to the same
window, the current content canvas can be replaced by another content canvas
under the following circumstances:
·
the end user or the application navigates to an
item on another content canvas assigned to the same window
·
a trigger or user-named subprogram executes the
REPLACE_CONTENT_VIEW built-in procedure.
For example, the end user might press [Next Item] (Tab) to
navigate to an item on a different content canvas. Since a window can display
only one content canvas at a time, Oracle Forms replaces the window's current
content canvas with the new content canvas that contains the target item
