\section{\class{wxDataViewIndexListModel}}\label{wxdataviewindexlistmodel}
|
|
|
|
wxDataViewIndexListModel is a specialized data model which lets
|
|
you address an item by its position (row) rather than its
|
|
wxDataViewItem (which you can obtain from this class).
|
|
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.
