## Detailed Description

### template<>
class Glib::Variant< gint16 >

Specialization of Glib::Variant containing a gint16 type.

Since glibmm 2.26:

## Member Typedef Documentation

using Glib::Variant< gint16 >::CType = gint16

## Constructor & Destructor Documentation

Glib::Variant< gint16 >::Variant | ( |  | ) |
| inline

Default constructor.

Glib::Variant< gint16 >::Variant | ( | GVariant< gint16 > * | 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).

## Member Function Documentation

static Variant<gint16> Glib::Variant< gint16 >::create | ( | gint16 | data | ) |
| static

Creates a new Glib::Variant<gint16>.

Parameters

  data | The value of the new Glib::Variant<gint16>.

Returns
  The new Glib::Variant<gint16>.

gint16 Glib::Variant< gint16 >::get | ( |  | ) | const

Gets the value of the Glib::Variant<gint16>.

Returns
  The gint16 value of the Glib::Variant<gint16>.

static const VariantType& Glib::Variant< gint16 >::variant_type | ( |  | ) |
| static

Gets the Glib::VariantType.

Returns
  The Glib::VariantType.
