Arguments: basic-pane
Returns true if basic-pane has an active close button (a control on
the title bar which closes the window when clicked) and nil otherwise. When nil, a
close button appears but it is unavailable (grayed out).
The close-button property may not be changed on an existing window, and must instead be specified with the inspector when designing a window (using a form) or with the :close-button initarg of make-window. (It can be changed using the inspector when designing a form but not for a running window or control, either in the IDE or in an application.)
