\section{\class{wxListCtrl}}\label{wxlistctrl}
A list control presents lists in a number of formats: list view, report view,
control is a virtual control in which the items data (including text, images
and attributes) is managed by the main program and is requested by the control
itself only when needed which allows to have controls with millions of items
-without consuming much memory. To use virtual list control you must use
-\helpref{SetItemCount}{wxlistctrlsetitemcount} first and overload at least
-\helpref{OnGetItemText}{wxlistctrlongetitemtext} (and optionally

about the items when the control requests it. Virtual list control can be used
as a normal one except that no operations which can take time proportional to
