Struct

GObjectTypeInterface

Description

struct GTypeInterface {
  /* No available fields */
}

An opaque structure used as the base of all interface types.

Functions

g_type_interface_add_prerequisite

Adds prerequisite_type to the list of prerequisites of interface_type. This means that any type implementing interface_type must also implement prerequisite_type. Prerequisites can be thought of as an alternative to interface derivation (which GType doesn’t support). An interface can have at most one instantiatable prerequisite type.

g_type_interface_get_plugin

Returns the GTypePlugin structure for the dynamic interface interface_type which has been added to instance_type, or NULL if interface_type has not been added to instance_type or does not have a GTypePlugin structure. See g_type_add_interface_dynamic().

g_type_interface_instantiatable_prerequisite

Returns the most specific instantiatable prerequisite of an interface type. If the interface type has no instantiatable prerequisite, G_TYPE_INVALID is returned.

since: 2.68

g_type_interface_peek

Returns the GTypeInterface structure of an interface to which the passed in class conforms.

g_type_interface_prerequisites

Returns the prerequisites of an interfaces type.

since: 2.2

Instance methods

g_type_interface_peek_parent

Returns the corresponding GTypeInterface structure of the parent type of the instance type to which g_iface belongs. This is useful when deriving the implementation of an interface from the parent type and then possibly overriding some methods.
