Detailed Description

Specialization of Glib::Variant containing a unsigned char type.

Since glibmm 2.26:

Member Typedef Documentation

◆ CType

using Glib::Variant< unsigned char >::CType = guchar

Constructor & Destructor Documentation

◆ Variant() [1/2]

Glib::Variant< unsigned char >::Variant ( )

inline

Default constructor.

◆ Variant() [2/2]

Glib::Variant< unsigned char >::Variant	(	GVariant< unsigned char > *	castitem,
		bool	take_a_reference = `false`
	)

inlineexplicit

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).
