Example

// This function returns the bounding rect that specifies the absolute position of the cell.
L_INT GetAbsolutePosition(HDISPCONTAINER hCon, L_INT nCellIndex, RECT L_FAR * lpRect)
{
   RECT  rcRect;
   POINT pt;

   // Check whether the cell index is valid or not.
   L_INT nCount = L_DispContainerGetCellCount(hCon, 0);
   if (nCellIndex < 0 || nCellIndex >= nCount)
      return 0;

   // Get the container window handle.
   hWndContainer = L_DispContainerGetWindowHandle (hCon, 0);

   // Get the cells bounding rectangle, the corrdinates is relative to the upperleft corner
   // of the container window.
   L_DispContainerGetCellBounds(hCon, nCellIndex, &rcRect, 0);

   pt.x = rcRect.left;
   pt.y = rcRect.top;

   ClientToScreen(hWndContainer, &pt);

   // Get the window handle of the cell
   hWndCell = L_DispContainerGetCellWindowHandle(hCon, nCellIndex, 0);

   // Get the client rect for the cell.
   GetClientRect(hWndCell, &rcRect);

   OffsetRect(&rcRect, pt.x, pt.y);

   CopyRect(lpRect, &rcRect);
