Glib::ParamSpec(3pm) |
 |
Glib::ParamSpec − Wrapper to encapsulate metadate needed to specify parameters
void DESTROY (GParamSpec * pspec)
|
g_param_spec_unref (pspec); |
Glib::ParamSpec encapsulates the metadata required to specify parameters. You will see these most often when creating new Glib::Object types; see "Glib::Type−>register" and Glib::Object::Subclass.
Parameter specifications allow you to provide limits for validation as well as nicknames and blurbs to document the parameters. Blurbs show up in reference documentation such as this page or the gtk+ C API reference; i’m not really sure where the nicknames get used. The Perl bindings for the most part ignore the difference between dashes and underscores in the paramspec names, which typically find use as the actual keys for object parameters.
It’s worth noting that Glib offers various sizes of integer and floating point values, while Perl really only deals with full integers and double precision floating point values. The size distinction is important for the underlying C libraries.
