Signature

(widget-plist-member PLIST PROP &optional PREDICATE)

Documentation

Return non-nil if PLIST has the property PROP.

PLIST is a property list, which is a list of the form
(PROP1 VALUE1 PROP2 VALUE2 ...).

The comparison with PROP is done using PREDICATE, which defaults to eq.

Unlike plist-get, this allows you to distinguish between a missing property and a property with the value nil. The value is actually the tail of PLIST whose car is PROP.

Probably introduced at or before Emacs version 21.1.
