Detailed Description

template<>

class Glib::Variant< guint16 >

Specialization of Glib::Variant containing a guint16 type.

Since glibmm 2.26:

Member Typedef Documentation

using Glib::Variant < guint16 >:: CType = guint16

Constructor & Destructor Documentation

Glib::Variant < guint16 >:: Variant ( )
inline

Default constructor.

Glib::Variant < guint16 >:: Variant ( GVariant< guint16 > * castitem ,
bool take_a_reference = false
)
inline explicit

GVariant constructor.

Parameters
castitem The GVariant to wrap.
take_a_reference Whether to take an extra reference of the GVariant or not (not taking one could destroy the GVariant with the wrapper).
