Declaration

flags GObject.SignalFlags

Description [src]

The signal flags are used to specify a signal’s behaviour.

Members

G_SIGNAL_RUN_FIRST

Invoke the object method handler in the first emission stage.

  • Value: 1
  • Available since: 2.0
G_SIGNAL_RUN_LAST

Invoke the object method handler in the third emission stage.

  • Value: 2
  • Available since: 2.0
G_SIGNAL_RUN_CLEANUP

Invoke the object method handler in the last emission stage.

  • Value: 4
  • Available since: 2.0
G_SIGNAL_NO_RECURSE

Signals being emitted for an object while currently being in emission for this very object will not be emitted recursively, but instead cause the first emission to be restarted.

  • Value: 8
  • Available since: 2.0
G_SIGNAL_DETAILED

This signal supports “::detail” appendices to the signal name upon handler connections and emissions.

  • Value: 16
  • Available since: 2.0
G_SIGNAL_ACTION

Action signals are signals that may freely be emitted on alive objects from user code via g_signal_emit() and friends, without the need of being embedded into extra code that performs pre or post emission adjustments on the object. They can also be thought of as object methods which can be called generically by third-party code.

  • Value: 32
  • Available since: 2.0
G_SIGNAL_NO_HOOKS

No emissions hooks are supported for this signal.

  • Value: 64
  • Available since: 2.0
G_SIGNAL_MUST_COLLECT

Varargs signal emission will always collect the arguments, even if there are no signal handlers connected. Since 2.30.

  • Value: 128
  • Available since: 2.0
G_SIGNAL_DEPRECATED

The signal is deprecated and will be removed in a future version. A warning will be generated if it is connected while running with G_ENABLE_DIAGNOSTIC=1. Since 2.32.

  • Value: 256
  • Available since: 2.0
G_SIGNAL_ACCUMULATOR_FIRST_RUN

Only used in GSignalAccumulator accumulator functions for the GSignalInvocationHint::run_type field to mark the first call to the accumulator function for a signal emission. Since 2.68.

  • Value: 131072
  • Available since: 2.0
