Struct
GObjectTypeInterface
Description [src]
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.
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.
