Close (Choice)

Provide the Close choice in the window menu of every window.

When a user activates the Close choice for the last primary window displayed for an application, remove all dependent secondary windows and exit from the application.

When a user activates the Close choice for a window, remove the window and any dependent secondary windows.

Use a Close push button to close an in-progress message window without affecting the task in progress. Do not terminate the task when a user presses the Close push button in an in-progress message window.

If information in a primary window could be lost when the user activates the Close choice, display a warning message.
