Arguments: multi-picture-button
Returns a list of the names of a multi-picture-button's buttons that are present
but not currently usable. The value may be set at creation time by
passing the unavailable-buttons initarg, or any
time later by calling (setf unavailable-buttons). The
argument multi-picture-button must be a
multi-picture-button.
The value should be a list of symbols, where each symbol is the name
of one of the button-infos
in the range of
multi-picture-button. The default value is
nil.
This property is useful for temporarily disallowing the use of one or more buttons, while leaving them present in their usual positions for context.
An alternative is the hidden-buttons property, which completely removes buttons from view.
