phoenix_title wx.dataview.DataViewIndexListModel

wx.dataview.DataViewIndexListModel is a specialized data model which lets you address an item by its position (row) rather than its wx.dataview.DataViewItem (which you can obtain from this class).

This model also provides its own wx.dataview.DataViewIndexListModel.Compare method which sorts the model’s data by the index.

This model is not a virtual model since the control stores each wx.dataview.DataViewItem. Use wx.dataview.DataViewVirtualListModel if you need to display millions of items or have other reason to use a virtual control.

See also

wx.dataview.DataViewListModel for the API.
