## unavailable-buttons

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-info`s 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.
