GtkTypeObject

typedef GTypeInstance GtkTypeObject;

A GtkTypeObject defines the minimum structure requirements for type instances. Type instances returned from gtk_type_new() and initialized through a GtkObjectInitFunc need to directly inherit from this structure or at least copy its fields one by one.

GtkArg

typedef struct {
GtkType type;
gchar *name;
/* this union only defines the required storage types for
* the possibile values, thus there is no gint enum_data field,
* because that would just be a mere alias for gint int_data.
* use the GTK_VALUE_*() and GTK_RETLOC_*() macros to access
* the discrete memebers.
*/
union {
/* flat values */
gchar char_data;
guchar uchar_data;
gboolean bool_data;
gint int_data;
guint uint_data;
glong long_data;
gulong ulong_data;
gfloat float_data;
gdouble double_data;
gchar *string_data;
