Function

GObjectTypeInterfaceadd_prerequisite

Declaration

void
g_type_interface_add_prerequisite (
  GType interface_type,
  GType prerequisite_type
)

Description

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.

Parameters

interface_type GType
 

GType value of an interface type.

prerequisite_type GType
 

GType value of an interface or instantiatable type.
