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-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.
