Arguments: multi-picture-button
Returns a list of the names of
multi-picture-button's buttons that currently do
not appear on the widget at all.
multi-picture-button must be a multi-picture-button. The value
may be set at creation time by passing the
hidden-buttons initarg, or any time later by
calling (setf
hidden-buttons).
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 removing one or more buttons completely from view, in a way that makes it easy to restore them later to their usual positions within multi-picture-button.
An alternative is the unavailable-buttons property, which grays out buttons and makes them unusable while leaving them present in their usual positions. A more basic alternative is to modify the range property.
