Variant.this

Depending on if @child is %NULL, either wraps @child inside of a maybe container or creates a Nothing instance for the given @type.

At least one of @child_type and @child must be non-%NULL. If @child_type is non-%NULL then it must be a definite type. If they are both non-%NULL then @child_type must be the type of @child.

If @child is a floating reference (see g_variant_ref_sink()), the new instance takes ownership of @child.

Parameters

childType VariantType

the #GVariantType of the child, or %NULL

child Variant

the child value, or %NULL

Return: a floating reference to a new #GVariant maybe instance

Throws

ConstructionException GTK+ fails to create the object.
