## Detailed Description

wxDataViewListStore is a specialised wxDataViewModel for storing a simple table of data.

Since it derives from wxDataViewIndexListModel its data is be accessed by row (i.e. by index) instead of only by wxDataViewItem.

This class actually stores the values (therefore its name) and implements all virtual methods from the base classes so it can be used directly without having to derive any class from it, but it is mostly used from within wxDataViewListCtrl.
