Function Macro

GObjectDEFINE_BOXED_TYPE_WITH_CODE

Declaration

#define G_DEFINE_BOXED_TYPE_WITH_CODE (
  TypeName,
  type_name,
  copy_func,
  free_func,
  _C_
)

Description

A convenience macro for boxed type implementations.

Similar to G_DEFINE_BOXED_TYPE(), but allows to insert custom code into the type_name_get_type() function, e.g. to register value transformations with g_value_register_transform_func(), for instance:

G_DEFINE_BOXED_TYPE_WITH_CODE (GdkRectangle, gdk_rectangle,
                               gdk_rectangle_copy,
                               gdk_rectangle_free,
                               register_rectangle_transform_funcs (g_define_type_id))

Similarly to the G_DEFINE_TYPE_* family of macros, the GType of the newly defined boxed type is exposed in the g_define_type_id variable.
