Struct ObjectPropertyChangedObservable 

pub struct ObjectPropertyChangedObservable { /* private fields */ }

The change notifications of one property on one object.

Returned by get_property_changed_observable. Change notifications borrow their values, so handlers are closures rather than observers. The object is held weakly.

Implementations

impl ObjectPropertyChangedObservable

pub fn subscribe( &self, handler: impl Fn(&FerroPropertyChangedEventArgs<'_>) + 'static, ) -> Rc<dyn IDisposable>

Subscribes to changes of the property on the object. Disposing the returned handle unsubscribes.

pub fn add_class_handler<TTarget: ObjectType>( &self, handler: impl Fn(&TTarget, &FerroPropertyChangedEventArgs<'_>) + 'static, ) -> Rc<dyn IDisposable>

Subscribes a handler that is only invoked when the object is of class TTarget (or a class derived from it).

Trait Implementations

impl Clone for ObjectPropertyChangedObservable

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
