/*
    The wxListCtrl can show lists of items in four different modes:
    wxLC_LIST:   multicolumn list view, with optional small icons (icons could be
                 optional for some platforms). Columns are computed automatically,
                 i.e. you don't set columns as in wxLC_REPORT. In other words,
                 the list wraps, unlike a wxListBox.
    wxLC_REPORT: single or multicolumn report view (with optional header)
    wxLC_ICON:   large icon view, with optional labels
    wxLC_SMALL_ICON: small icon view, with optional labels

    You can change the style dynamically, either with SetSingleStyle or
    SetWindowStyleFlag.

    Further window styles:

    wxLC_ALIGN_TOP          icons align to the top (default)
    wxLC_ALIGN_LEFT         icons align to the left
    wxLC_AUTOARRANGE        icons arrange themselves
    wxLC_USER_TEXT          the app provides label text on demand, except for column headers
    wxLC_EDIT_LABELS        labels are editable: app will be notified.
    wxLC_NO_HEADER          no header in report mode
    wxLC_NO_SORT_HEADER     can't click on header
    wxLC_SINGLE_SEL         single selection
    wxLC_SORT_ASCENDING     sort ascending (must still supply a comparison callback in SortItems)
    wxLC_SORT_DESCENDING    sort descending (ditto)

    Items are referred to by their index (position in the list starting from zero).

    Label text is supplied via insertion/setting functions and is stored by the
    control, unless the wxLC_USER_TEXT style has been specified, in which case
    the app will be notified when text is required (see sample).

    Images are dealt with by (optionally) associating 3 image lists with the control.
    Zero-based indexes into these image lists indicate which image is to be used for
    which item. Each image in an image list can contain a mask, and can be made out
    of either a bitmap, two bitmaps or an icon. See ImagList.h for more details.

    Notifications are passed via the wxWidgets 2.0 event system, or using virtual
    functions in wxWidgets 1.66.

    See the sample wxListCtrl app for API usage.

    TODO:
     - addition of further convenience functions
       to avoid use of wxListItem in some functions
     - state/overlay images: probably not needed.
     - in Win95, you can be called back to supply other information
       besides text, such as state information. This saves no memory
       and is probably superfluous to requirements.
     - testing of whole API, extending current sample.
