Function

GObjectsignal_emit

Declaration

void
g_signal_emit (
  GObject* instance,
  guint signal_id,
  GQuark detail,

Description

Emits a signal. Signal emission is done synchronously. The method will only return control after all handlers are called or signal emission was stopped.

Note that g_signal_emit() resets the return value to the default if no handlers are connected, in contrast to g_signal_emitv().

This function is not directly available to language bindings

Parameters to be passed to the signal, followed by a location for the return value. If the return type of the signal is G_TYPE_NONE, the return value location can be omitted.
