  24  * NOTES
  25  * Listview control implementation.
  26  *
  27  * TODO:
  28  *   1. No horizontal scrolling when header is larger than the client area.
  29  *   2. Drawing optimizations.
  30  *   3. Hot item handling.
  31  *
  32  * Notifications:
  33  *   LISTVIEW_Notify : most notifications from children (editbox and header)
  34  *
  35  * Data structure:
  36  *   LISTVIEW_SetItemCount : not completed for non OWNERDATA
  37  *
  38  * Advanced functionality:
  39  *   LISTVIEW_GetNumberOfWorkAreas : not implemented
  40  *   LISTVIEW_GetHotCursor : not implemented
  41  *   LISTVIEW_GetISearchString : not implemented
  42  *   LISTVIEW_GetBkImage : not implemented
  43  *   LISTVIEW_SetBkImage : not implemented
  44  *   LISTVIEW_GetColumnOrderArray : simple hack only
  45  *   LISTVIEW_SetColumnOrderArray : simple hack only
  46  *   LISTVIEW_Arrange : empty stub
  47  *   LISTVIEW_ApproximateViewRect : incomplete
  48  *   LISTVIEW_Scroll : not implemented
  49  *   LISTVIEW_Update : not completed
  50  *
  51  * Known differences in message stream from native control (not known if
  52  * these differences cause problems):
  53  *   LVM_INSERTITEM issues LVM_SETITEMSTATE and LVM_SETITEM in certain cases.
  54  *   LVM_SETITEM does not always issue LVN_ITEMCHANGING/LVN_ITEMCHANGED.
  55  *   WM_PAINT does LVN_GETDISPINFO in item order 0->n, native does n->0.
  56  *   WM_SETREDRAW(True) native does LVN_GETDISPINFO for all items and
  57  *     does *not* invoke DefWindowProc
  58  *   WM_CREATE does not issue WM_QUERYUISTATE and associated registry
  59  *     processing for "USEDOUBLECLICKTIME".

 630  *              LISTVIEW_ProcessLetterKeys
 631  *
 632  *  Processes keyboard messages generated by pressing the letter keys
 633  *  on the keyboard.
 634  *  What this does is perform a case insensitive search from the
 635  *  current position with the following quirks:
 636  *  - If two chars or more are pressed in quick succession we search
 637  *    for the corresponding string (e.g. 'abc').
 638  *  - If there is a delay we wipe away the current search string and
 639  *    restart with just that char.
 640  *  - If the user keeps pressing the same character, whether slowly or
 641  *    fast, so that the search string is entirely composed of this
 642  *    character ('aaaaa' for instance), then we search for first item
 643  *    that starting with that character.
 644  *  - If the user types the above character in quick succession, then
 645  *    we must also search for the corresponding string ('aaaaa'), and
 646  *    go to that string if there is a match.
 647  *
 648  * RETURNS
 649  *
 650  *  Zero.
 651  *
 652  * BUGS
 653  *
 654  *  - The current implementation has a list of characters it will
 655  *    accept and it ignores averything else. In particular it will
 656  *    ignore accentuated characters which seems to match what
 657  *    Windows does. But I'm not sure it makes sense to follow
 658  *    Windows there.
 659  *  - We don't sound a beep when the search fails.
