Struct glib::SignalGroup
source · [−]#[repr(transparent)]pub struct SignalGroup { /* private fields */ }Expand description
SignalGroup manages to simplify the process of connecting
many signals to a Object as a group. As such there is no API
to disconnect a signal from the group.
In particular, this allows you to:
- Change the target instance, which automatically causes disconnection of the signals from the old instance and connecting to the new instance.
- Block and unblock signals as a group
- Ensuring that blocked state transfers across target instances.
One place you might want to use such a structure is with GtkTextView and
GtkTextBuffer. Often times, you’ll need to connect to many signals on
GtkTextBuffer from a GtkTextView subclass. This allows you to create a
signal group during instance construction, simply bind the
GtkTextView:buffer property to property::SignalGroup::target and connect
all the signals you need. When the GtkTextView:buffer property changes
all of the signals will be transitioned correctly.

Implementations
sourceimpl SignalGroup
impl SignalGroup
sourcepub fn new(target_type: Type) -> SignalGroup
Available on crate feature v2_74 only.
pub fn new(target_type: Type) -> SignalGroup
v2_74 only.Creates a new SignalGroup for target instances of target_type.
target_type
the GType of the target instance.
Returns
a new SignalGroup
sourcepub fn block(&self)
Available on crate feature v2_74 only.
pub fn block(&self)
v2_74 only.Blocks all signal handlers managed by self so they will not
be called during any signal emissions. Must be unblocked exactly
the same number of times it has been blocked to become active again.
This blocked state will be kept across changes of the target instance.
sourcepub fn set_target(&self, target: Option<&impl IsA<Object>>)
Available on crate feature v2_74 only.
pub fn set_target(&self, target: Option<&impl IsA<Object>>)
v2_74 only.Sets the target instance used when connecting signals. Any signal
that has been registered with g_signal_group_connect_object() or
similar functions will be connected to this object.
If the target instance was previously set, signals will be
disconnected from that object prior to connecting to target.
target
The target instance used when connecting signals.
sourcepub fn unblock(&self)
Available on crate feature v2_74 only.
pub fn unblock(&self)
v2_74 only.Unblocks all signal handlers managed by self so they will be
called again during any signal emissions unless it is blocked
again. Must be unblocked exactly the same number of times it
has been blocked to become active again.
sourcepub fn target_type(&self) -> Type
Available on crate features v2_74 and v2_72 only.
pub fn target_type(&self) -> Type
v2_74 and v2_72 only.The GType of the target property.

after: bool,
closure: RustClosure
)
Available on crate feature v2_74 only.
pub fn connect_closure(
&self,
signal_name: &str,
after: bool,
closure: RustClosure
)
v2_74 only.Connects closure to the signal detailed_signal on property::SignalGroup::target.
You cannot connect a signal handler after property::SignalGroup::target has been set.
detailed_signal
a string of the form signal-name with optional ::signal-detail
closure
the closure to connect.
after
whether the handler should be called before or after the default handler of the signal.

v2_74 only.Connects c_handler to the signal detailed_signal
on the target instance of self.
You cannot connect a signal handler after property::SignalGroup::target has been set.

v2_74 only.Like Self::connect but doesn’t require a Send+Sync closure. Signal emission will
panic if the signal on the current target is emitted from a different thread from the
thread that connected the signal.

&self,
f: F
) -> SignalHandlerId
Available on crate feature v2_74 only.
pub fn connect_bind<F: Fn(&Self, &Object) + Send + Sync + 'static>(
&self,
f: F
) -> SignalHandlerId
v2_74 only.This signal is emitted when property::SignalGroup::target is set to a new value
other than None. It is similar to signal::Object::notify on target except it
will not emit when property::SignalGroup::target is None and also allows for
receiving the Object without a data-race.
instance

v2_74 only.Like Self::connect_unbind but doesn’t require a Send+Sync closure. Signal emission
will panic if the signal is emitted from a different thread from the thread that connected
the signal.
