ParamSpecVariantRef
public struct ParamSpecVariantRef : ParamSpecVariantProtocol
A GParamSpec
derived structure that contains the meta data for GVariant
properties.
When comparing values with g_param_values_cmp()
, scalar values with the same
type will be compared with g_variant_compare()
. Other non-nil
variants will
be checked for equality with g_variant_equal()
, and their sort order is
otherwise undefined. nil
is ordered before non-nil
variants. Two nil
values compare equal.
The ParamSpecVariantRef
type acts as a lightweight Swift reference to an underlying GParamSpecVariant
instance.
It exposes methods that can operate on this data type through ParamSpecVariantProtocol
conformance.
Use ParamSpecVariantRef
only as an unowned
reference to an existing GParamSpecVariant
instance.

Untyped pointer to the underlying `GParamSpecVariant` instance.

param_spec_variant_ptr
property instead.Declaration
