[Bug 15833] TreeView control don't save item's state

[Vadim Zavgorodniy]

Hi.

BUG:
TreeView sends TVS_GETDISPINFO notifycation. Main application catch it and
change "mask","state" and "stateMask" in a TVITEM structure. After returning

from message handler, item's state don't changed. TreeView don't save new item



state in function TREEVIEW_UpdateDispInfo after calling
TREEVIEW_SendRealNotify.

This is Delphi code sample, TMyTreeView inherits from TCustomTreeView

//-----------------------------------------------------------------



procedure TMyTreeView.CNNotify(var Message: TWMNotify);
var
  hNode: Integer;
begin
  with Message do
  case NMHdr^.code of
  TVN_GETDISPINFO:

    with PTVDispInfo(NMHdr)^ do begin

      hNode := item.hItem;



      with PTVDispInfo(NMHdr)^.item do begin
        mask := mask or TVIF_STATE or TVIF_HANDLE;
        stateMask := stateMask or TVIS_STATEIMAGEMASK;

        state := (state and not TVIS_STATEIMAGEMASK)


          or UINT(IndexToStateImageMask(MyGetItemImageIndex(hNode)));

      end;
    end;
  end;

  inherited;
end;
//-----------------------------------------------------------------
