Trait gdk_pixbuf::subclass::prelude::IsSubclassable

pub unsafe trait IsSubclassable<T>: IsSubclassableDefault<T>where
    T: ObjectSubclass,{
    fn class_init(class: &mut Class<Self>) { ... }
    fn instance_init(instance: &mut InitializingObject<T>) { ... }
}

Trait for subclassable class structs.

Provided Methods

fn class_init(class: &mut Class<Self>)

Override the virtual methods of this class for the given subclass and do other class initialization.

This is automatically called during type initialization and must call class_init() of the parent class.

fn instance_init(instance: &mut InitializingObject<T>)

Instance specific initialization.

This is automatically called during instance initialization and must call instance_init() of the parent class.
