Required methods

fn insert_local_state(&self, env: &mut Environment<S>)

Insert local state from the widget into the environment. Return true if any of the keys from the widget was already in the local state.

fn update_all_widget_state(&mut self, env: &Environment<S>, global_state: &S)

Update the state for this widget. Update both local, global and environment state

fn update_local_widget_state(&mut self, env: &Environment<S>)

Update only the local state for the widget

fn sync_state(&mut self, env: &mut Environment<S>, global_state: &S)

This should be implemented to synchronize both global and local state. A general implementation should:

• Update the widget state, both global and local
• Insert its own local state into the environment
• Iterate though its children and sync_state on each You can in most cases use default_sync_state
