\section{\class{wxListView}}\label{wxlistview}

This class currently simply presents a simpler to use interface for the 
\helpref{wxListCtrl}{wxlistctrl} -- it can be thought of as a {\it fa\c{c}ade}
for that complicated class. Using it is preferable to using 
\helpref{wxListCtrl}{wxlistctrl} directly whenever possible because in the
future some ports might implement wxListView but not the full set of wxListCtrl
features.

Other than different interface, this class is identical to wxListCtrl. In
particular, it uses the same events, same windows styles and so on.
