/*
* Listview control
*
* Copyright 1998 Eric Kohl
* Copyright 1999 Luc Tourangeau
*
* NOTES
* Listview control implementation.
*
* TODO:
* 1. No horizontal scrolling when header is larger than the client area.
* 2. Drawing optimizations.
*
* Notifications:
* LISTVIEW_Notify : most notifications from children (editbox and header)
*
* Data structure:
* LISTVIEW_SortItems : empty stub
* LISTVIEW_SetItemCount : empty stub
*
* Unicode:
* LISTVIEW_SetItem32W : no unicode support
* LISTVIEW_InsertItem32W : no unicode support
* LISTVIEW_InsertColumn32W : no unicode support
* LISTVIEW_GetColumnW : no unicode support
*
* Advanced functionality:
* LISTVIEW_GetNumberOfWorkAreas : not implemented
* LISTVIEW_GetHotCursor : not implemented
* LISTVIEW_GetHotItem : not implemented
* LISTVIEW_GetHoverTime : not implemented
* LISTVIEW_GetISearchString : not implemented
* LISTVIEW_GetBkImage : not implemented
* LISTVIEW_EditLabel : REPORT (need to implement a timer)
* LISTVIEW_GetColumnOrderArray : not implemented
* LISTVIEW_Arrange : empty stub
* LISTVIEW_ApproximateViewRect : incomplete
* LISTVIEW_Scroll : not implemented
* LISTVIEW_RedrawItems : empty stub
* LISTVIEW_Update : not completed
