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, Form Builder displays the window with its primary content view.
However, if Forms needs to display a different content view because of navigation to an item on that view, the primary content view is superseded by the target view.

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.
