Parameters
view_id Specifies the unique ID that Form Builder assigns the canvas when it
creates the object. Use the FIND_VIEW built-in to return the ID to an
appropriately typed variable. The data type of the ID is ViewPort.
view_name Specifies the name that you gave the object when defining it.

You must make a separate call to GET_VIEW_PROPERTY for each

following constants to obtain return values:

DIRECTION Returns the layout direction for bidirectional objects. Valid
return values are RIGHT_TO_LEFT, LEFT_TO_RIGHT.
HEIGHT Returns the height of the view. For a content view, the height of

Coordinate System property for the form module.

upper left corner of the window’s current content canvas. For a content
view, returns 0. The value is returned as a VARCHAR2 and is expressed in
the units defined by the form module Coordinate System property.

reflects the current placement of the view’s upper left corner relative to the
upper left corner of the window’s current content canvas. For a content
view, returns 0. The value is returned as a VARCHAR2 and is expressed in
the units defined by the form module Coordinate System property.
