Struct glib::subclass::ObjectImplRef

source ·
pub struct ObjectImplRef<T: ObjectSubclass>(/* private fields */);
Expand description

Reference-counted wrapper around an ObjectSubclass reference.

This can be used for passing into closures as strong or weak reference without manually going from the implementation type to the instance type and back.

Implementations§

source§

impl<T: ObjectSubclass> ObjectImplRef<T>

source

pub fn new(imp: &T) -> Self

Create a new reference-counting wrapper around imp.

source

pub fn downgrade(&self) -> ObjectImplWeakRef<T>
