Detailed Description

A wxDataViewModelNotifier that runs a callback whenever the model removes items or resets.

WX_DATAVIEWCTRL installs one so a deferred EnsureVisible (see WX_DATAVIEWCTRL::CancelPendingEnsureVisible) drops automatically as the model frees items, rather than relying on every model-mutation site to cancel it by hand.
