Glib::Param::UInt HIERARCHY
Glib::ParamSpec +----Glib::Param::UInt DESCRIPTION
This page documents the extra accessors available for all of the unsigned integer type paramspecs: UChar, UInt, and ULong. Perl really only supports full-size integers, so all of these methods return UVs; the distinction of integer size is important to the underlying C library and also determines the data value range.

Glib::ParamSpec(3) User Contributed Perl Documentation Glib::ParamSpec(3) NAME
Glib::ParamSpec DESCRIPTION
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. HIERARCHY

$pspec->get_value_type bool = $paramspec->value_validate ($value) (bool, newval) = $paramspec->value_validate ($value) o $value (scalar) In scalar context return true if $value must be modified to be valid for $paramspec, or false if it's valid already. In array context return also a new value which is $value made valid. $value must be the right type for $paramspec (with usual stringizing, numizing, etc). "value_validate" checks the further restrictions such as minimum and maximum for a numeric type or allowed characters in a string. The "made valid" return is then for instance clamped to the min/max, or offending chars replaced by a substitutor. integer = $pspec->values_cmp ($value1, $value2) o $value1 (scalar) o $value2 (scalar) Compares value1 with value2 according to pspec, and returns -1, 0 or +1, if value1 is found to be less than, equal to or greater than value2, respectively.
