Struct BoundObjectWeakRef

pub struct BoundObjectWeakRef<T: ObjectType> {
    weak_obj: WeakRef<T>,
    signal_handler_ids: RefCell<Vec<SignalHandlerId>>,
}

Wrapper to manage a bound object.

This keeps a weak reference to the object.

Fields

weak_obj: WeakRef<T>

signal_handler_ids: RefCell<Vec<SignalHandlerId>>

Implementations

impl<T: ObjectType> BoundObjectWeakRef<T>

pub fn new() -> Self

Creates a new empty BoundObjectWeakRef.

pub fn set(&self, obj: &T, signal_handler_ids: Vec<SignalHandlerId>)

Set the given object and signal handlers IDs.

Calls disconnect_signals first to remove the previous weak reference and disconnect the previous signal handlers.

pub fn obj(&self) -> Option<T>

Get a strong reference to the object.

pub fn disconnect_signals(&self)

Disconnect the signal handlers and drop the weak reference.
