Struct glib::SignalFlags [−][src]
pub struct SignalFlags { /* fields omitted */ }
Expand description
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.
Implementations
Invoke the object method handler in the first emission stage.
Invoke the object method handler in the third emission stage.
Invoke the object method handler in the last emission stage.
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.
This signal supports “::detail” appendices to the signal name upon handler connections and emissions.
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.
No emissions hooks are supported for this signal.
Varargs signal emission will always collect the arguments, even if there are no signal handlers connected. Since 2.30.
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.
Returns an empty set of flags
Returns the set containing all flags.
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).
Returns true
if there are flags common to both self
and other
.
Returns true
all of the flags in other
are contained within self
.
Inserts the specified flags in-place.
Removes the specified flags in-place.
Toggles the specified flags in-place.
Inserts or removes the specified flags depending on the passed value.
