# Glib::Param::GType(3pm)

Wrapper for type parameters in GLib

## NAME

Glib::Param::GType - Wrapper for type parameters in GLib

## HIERARCHY

```
  Glib::ParamSpec
  +----Glib::Param::GType
```

## DESCRIPTION

This object describes a parameter which holds the name of a class known to the GLib type system.  The name of the class is considered to be the common ancestor for valid values.  To create a param that allows any type name, specify `"undef"` for the package name.  Beware, however, that although we say "any type name", this actually refers to any type registered with Glib; normal Perl packages will not work.

## METHODS

### string or undef = $pspec\_gtype-\>get\_is\_a\_type

If `"undef"`, then any class is allowed.

Since: glib 2.10

Glib, Glib::ParamSpec
