Module GObject_introspection.Signal_info
type tSignal_info represents a signal. It's a sub-struct of Callable_info and contains a set of flags and a class closure. See Callable_info for information on how to retreive arguments and other metadata from the signal.
val signalinfo : t Ctypes.structure Ctypes.typval true_stops_emit : t Ctypes.structure Ctypes.ptr -> boolObtain if the returning true in the signal handler will stop the emission of the signal.
val get_flags : t Ctypes.structure Ctypes.ptr -> Bindings.GSignal.flags listObtain the flags for this signal info. See GSignalFlags for more information about possible flag values.
val get_class_closure : t Ctypes.structure Ctypes.ptr -> Callable_info.t Ctypes.structure Ctypes.ptr optionObtain the class closure for this signal if one is set. The class closure is a virtual function on the type that the signal belongs to. If the signal lacks a closure None will be returned. In order to avoid circular call graph between Signal_info and VFunc_info, this function will return a Callable_info. It is upto the user to use GIVSignalInfo.from_callableinfo in order to have the VFunc_info.
val cast_from_baseinfo : Base_info.t Ctypes.structure Ctypes.ptr -> t Ctypes.structure Ctypes.ptrJust cast OCaml Ctypes base info to signal info.
val cast_to_baseinfo : t Ctypes.structure Ctypes.ptr -> Base_info.t Ctypes.structure Ctypes.ptrJust cast OCaml Ctypes signal info to base info
val add_unref_finaliser : t Ctypes.structure Ctypes.ptr -> t Ctypes.structure Ctypes.ptrAdd unref of the C underlying structure whith Gc.finalise.
val from_baseinfo : Base_info.t Ctypes.structure Ctypes.ptr -> t Ctypes.structure Ctypes.ptrReturn a Signal_info.t from a Base_info.t, the underlying C structure ref count is increased and the value is Gc.finalis"ed" with Base_info.baseinfo_unref.
val to_baseinfo : t Ctypes.structure Ctypes.ptr -> Base_info.t Ctypes.structure Ctypes.ptrReturn a Base_info.t from a Signal_info, the underlying C structure ref count is increased and the value is Gc.finalis"ed" with Base_info.baseinfo_unref.
val cast_from_callableinfo : Callable_info.t Ctypes.structure Ctypes.ptr -> t Ctypes.structure Ctypes.ptrJust cast OCaml Ctypes callable info to signal info.
val cast_to_callableinfo : t Ctypes.structure Ctypes.ptr -> Callable_info.t Ctypes.structure Ctypes.ptrJust cast OCaml Ctypes signal info to callable info
val from_callableinfo : Callable_info.t Ctypes.structure Ctypes.ptr -> t Ctypes.structure Ctypes.ptrReturn a Signal_info.t from a Callable_info.t, the underlying C structure ref count is increased and the value is Gc.finalis"ed" with Base_info.baseinfo_unref.
val to_callableinfo : t Ctypes.structure Ctypes.ptr -> Callable_info.t Ctypes.structure Ctypes.ptrReturn a Callable_info.t from a Signal_info, the underlying C structure ref count is increased and the value is Gc.finalis"ed" with Base_info.baseinfo_unref.
