@ -8,6 +8,13 @@ This model also provides its own
|

\helpref{Compare}{wxdataviewindexlistmodelcompare} method
|

which sorts the model's data by the index.

|
||||
This model is special in the it is implemented differently under OS X
|
||||
and other platforms. Under OS X a wxDataViewItem is always persistent
|
||||
and this is also the case for this class. Under other platforms, the
|
||||
meaning of a wxDataViewItem is changed to reflect a row number for
|
||||
wxDataViewIndexListModel. The consequence of this is that
|
||||
wxDataViewIndexListModel can be used as a virtual model with an
|
||||
almost infinate number of items on platforms other than OS X.
