Function

GObject-2.0 ▶ GObject ▶ signal_connect_closure_by_id

  • Connects a closure to a signal for a particular object.

    If closure is a floating reference (see g_closure_sink()), this function takes ownership of closure.

    This function cannot fail. If the given signal name doesn’t exist, a critical warning is emitted. No validation is performed on the ‘detail’ string when specified in detailed_signal, other than a non-empty check.

    Refer to the signals documentation for more details.
