New Window (Choice)

Provide a New Window choice in the View menu if your application allows a user to display a new window that contains another view of the data viewed in the current window.

When New Window is an action choice, choosing it displays a new window that contains the same view of the data as the current window, or a default view.

When New Window is a cascading choice, its cascaded menu must list the views available to be shown in the new window.

Make New Window an action choice when a user is most likely to want the new window to show the view that will be chosen (for example, either the same view or a default view).

Make New Window a cascading choice when a user is most likely to want the new window to show a different view than is being viewed in the current window.

If you use a cascading choice for New Window, and you cannot show additional windows of some views, display choices for those views in the cascaded menu with unavailable emphasis.

Use a property that the user can set to determine whether New Window uses the view in the current window or a default view.

Do not change the underlying data being viewed when the user opens a window that contains a new view.

If you use multiple windows to display the same type of view of a file or object, and the user makes a File menu choice in one of the windows to change the file or object being viewed, only that window is affected; the other windows contain the original file or object.
