The signal flags are used to specify a signal's behaviour, the overall
signal description outlines how especially the RUN flags control the
stages of a signal emission.
G_SIGNAL_RUN_FIRST
Invoke the object method handler in the first emission stage.
G_SIGNAL_RUN_LAST
Invoke the object method handler in the third emission stage.
G_SIGNAL_RUN_CLEANUP
Invoke the object method handler in the last emission stage.
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.
G_SIGNAL_DETAILED
This signal supports "::detail" appendices to the signal name
upon handler connections and emissions.
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.
G_SIGNAL_NO_HOOKS
No emissions hooks are supported for this signal.
