GObjectsignal_accumulator_true_handled

Declaration

gboolean
g_signal_accumulator_true_handled (
  GSignalInvocationHint* ihint,
  GValue* return_accu,
  const GValue* handler_return,
  gpointer dummy
)

Description

A predefined GSignalAccumulator for signals that return a boolean values. The behavior that this accumulator gives is that a return of TRUE stops the signal emission: no further callbacks will be invoked, while a return of FALSE allows the emission to continue. The idea here is that a TRUE return indicates that the callback handled the signal, and no further handling is needed.
