    @class wxListCtrl
    @wxheader{listctrl.h}

    A list control presents lists in a number of formats: list view, report view,
    icon view and small icon view. In any case, elements are numbered from zero.
    For all these modes, the items are stored in the control and must be added to
    it using wxListCtrl::InsertItem method.

    A special case of report view quite different from the other modes of the list
    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
    wxListCtrl::SetItemCount first and overload at least
    wxListCtrl::OnGetItemText (and optionally
    wxListCtrl::OnGetItemImage or wxListCtrl::OnGetItemColumnImage and
    wxListCtrl::OnGetItemAttr) to return the information
    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
    @ref overview_samplelistctrl "corresponding sample".

    To intercept events from a list control, use the event table macros described
    in wxListEvent.

    @b Mac Note: Starting with 2.8, wxListCtrl uses a native implementation for
    report mode, and uses a generic implementation for other modes. You can use the
    generic implementation for report mode as well by setting the
    mac.listctrl.always_use_generic wxSystemOption() to
    1.

    @beginStyleTable
    @style{wxLC_LIST}
           Multicolumn list view, with optional small icons. Columns are
           computed automatically, i.e. you don't set columns as in
           wxLC_REPORT. In other words, the list wraps, unlike a wxListBox.
    @style{wxLC_REPORT}
           Single or multicolumn report view, with optional header.
    @style{wxLC_VIRTUAL}
           The application provides items text on demand. May only be used
           with wxLC_REPORT.
    @style{wxLC_ICON}
           Large icon view, with optional labels.
    @style{wxLC_SMALL_ICON}
           Small icon view, with optional labels.
    @style{wxLC_ALIGN_TOP}
           Icons align to the top. Win32 default, Win32 only.
    @style{wxLC_ALIGN_LEFT}
           Icons align to the left.
    @style{wxLC_AUTOARRANGE}
           Icons arrange themselves. Win32 only.
    @style{wxLC_EDIT_LABELS}
           Labels are editable: the application will be notified when editing
           starts.
    @style{wxLC_NO_HEADER}
           No header in report mode.
    @style{wxLC_SINGLE_SEL}
           Single selection (default is multiple).
    @style{wxLC_SORT_ASCENDING}
           Sort in ascending order (must still supply a comparison callback in
           SortItems.
    @style{wxLC_SORT_DESCENDING}
           Sort in descending order (must still supply a comparison callback
           in SortItems.
    @style{wxLC_HRULES}
           Draws light horizontal rules between rows in report mode.
    @style{wxLC_VRULES}
           Draws light vertical rules between columns in report mode.
