Function

GObjectTypeInterfaceadd_prerequisite

Declaration [src]

void
g_type_interface_add_prerequisite (
  GType interface_type,
  GType prerequisite_type
)

[−]

Description [src]

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.

GType value of an interface or instantiatable type.
