   8  * NOTES
   9  * Listview control implementation.
  10  *
  11  * TODO:
  12  *   1. No horizontal scrolling when header is larger than the client area.
  13  *   2. Drawing optimizations.
  14  *   3. Hot item handling.
  15  *
  16  * Notifications:
  17  *   LISTVIEW_Notify : most notifications from children (editbox and header)
  18  *
  19  * Data structure:
  20  *   LISTVIEW_SetItemCount : not completed
  21  *
  22  * Unicode:
  23  *   LISTVIEW_SetItemW : no unicode support
  24  *   LISTVIEW_InsertItemW : no unicode support
  25  *   LISTVIEW_InsertColumnW : no unicode support
  26  *   LISTVIEW_GetColumnW : no unicode support
  27  *   LISTVIEW_SetColumnW : no unicode support
  28  *
  29  * Advanced functionality:
  30  *   LISTVIEW_GetNumberOfWorkAreas : not implemented
  31  *   LISTVIEW_GetHotCursor : not implemented
  32  *   LISTVIEW_GetISearchString : not implemented
  33  *   LISTVIEW_GetBkImage : not implemented
  34  *   LISTVIEW_GetColumnOrderArray : simple hack only
  35  *   LISTVIEW_SetColumnOrderArray : simple hack only
  36  *   LISTVIEW_Arrange : empty stub
  37  *   LISTVIEW_ApproximateViewRect : incomplete
  38  *   LISTVIEW_Scroll : not implemented
  39  *   LISTVIEW_RedrawItems : empty stub
