+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
+the number of items in the control happen -- this is required to allow having a
+practically infinite number of items. For example, in a multiple selection
+virtual list control, the selections won't be sent when many items are selected
+at once because this could mean iterating over all the items.
Using many of wxListCtrl features is shown in the

+\func{long}{FindItem}{\param{long }{start}, \param{const wxString\& }{str}, \param{const bool }{partial = false}}
Find an item whose label matches this string, starting from the item after {\it start} or
the beginning if {\it start} is -1.
\pythonnote{In place of a single overloaded method name, wxPython
implements the following methods:\par

\membersection{wxListCtrl::GetEditControl}\label{wxlistctrlgeteditcontrol}
-\constfunc{wxTextCtrl\&}{GetEditControl}{\void}
+\constfunc{wxTextCtrl *}{GetEditControl}{\void}

+Returns the edit control being currently used to edit a label. Returns {\tt NULL}

\membersection{wxListCtrl::GetItemSpacing}\label{wxlistctrlgetitemspacing}
-\constfunc{int}{GetItemSpacing}{\param{bool }{isSmall}}
+\constfunc{wxSize}{GetItemSpacing}{\void}
+
+Retrieves the spacing between icons in pixels: horizontal spacing is returned
+as \texttt{x} component of the \helpref{wxSize}{wxsize} object and the vertical
+spacing as its \texttt{y} component.
-Retrieves the spacing between icons in pixels.
-If {\it small} is TRUE, gets the spacing for the small icon
-view, otherwise the large icon view.

Gets the index of the topmost visible item when in
list or report view.
+
+\membersection{wxRect}{wxListCtrl::GetViewRect}\label{wxlistctrlgetviewrect}
+
+\constfunc{wxRect}{GetViewRect}{\void}
+
+Returns the rectangle taken by all items in the control. In other words, if the
+controls client size were equal to the size of this rectangle, no scrollbars
+would be needed and no free space would be left.
+
+Note that this function only works in the icon and small icon views, not in
+list or report views (this is a limitation of the native Win32 control).
