Struct ModelNotify

pub struct ModelNotify { /* private fields */ }

Dispatch notifications from a Model to one or several ModelPeer. Typically, you would want to put this in the implementation of the Model

Implementations

impl ModelNotify

pub fn row_changed(&self, row: usize)

Notify the peers that a specific row was changed

pub fn row_added(&self, index: usize, count: usize)

Notify the peers that rows were added

pub fn row_removed(&self, index: usize, count: usize)

Notify the peers that rows were removed

pub fn reset(&self)

Notify the peer that the model has been changed in some way and everything needs to be reloaded

Trait Implementations

impl Default for ModelNotify

fn default() -> ModelNotify

Returns the “default value” for a type.

impl ModelTracker for ModelNotify

fn attach_peer(&self, peer: ModelPeer<'_>)

Attach one peer. The peer will be notified when the model changes

fn track_row_count_changes(&self)

Register the model as a dependency to the current binding being evaluated, so that it will be notified when the model changes its size.

fn track_row_data_changes(&self, row: usize)

Register a row as a dependency to the current binding being evaluated, so that it will be notified when the value of that row changes.
