Bool package:haskell-gi-base

Add a `${type gboolean}`-valued property to the given object class.
Information on a property of type `type gboolean` to be registered. A property name consists of segments consisting of ASCII letters and digits, separated by either the '-' or '_' character. The first character of a property name must be a letter. Names which violate these rules lead to undefined behaviour. When creating and looking up a property, either separator can be used, but they cannot be mixed. Using '-' is considerably more efficient and in fact required when using property names as detail strings for signals. Beyond the name, properties have two more descriptive strings associated with them, the nick, which should be suitable for use as a label for the property in a property editor, and the blurb, which should be a somewhat longer description, suitable for e.g. a tooltip. The nick and blurb should ideally be localized.
Create a GParamSpec for a bool param.
