L_DispContainerRepositionCell

#include "ltivw.h"

L_LTIVW_API L_INT L_DispContainerRepositionCell(hCon, nCellIndex, nTargetIndex, bSwap, uFlags)

HDISPCONTAINER hCon;

handle to the container

L_INT nCellIndex;

the old cell index

L_INT nTargetIndex;

the new index of the cell

L_BOOL bSwap;

shift or swap flag

L_UINT uFlags;

reserved for future use

Sets the position of the specified cell, based on the index of the cell.

Parameter Description
hCon Handle to the container.
nCellIndex A zero-based index of the current cell position.
nTargetIndex A zero-based index of the new cell position.
bSwap Flag that indicates whether to perform swap on the cells specified in nCellIndex and nTargetIndex, or to shift the cells according to the parameters and then set the cell with nCellIndex, in the position of nTargetIndex.  Possible values are:
  Value Meaning
  TRUE Swap the cells.
  FALSE Shift the cells.
uFlags Reserved for future use. Pass 0.

Returns

SUCCESS

The function was successful.

< 1

An error occurred. Refer to Return Codes.

Comments

Set the bSwap flag to TRUE to swap the nCellIndex and nTargetIndex. Otherwise the function will shift the cells and then place the cell with the cell index nCellIndex in the exposed area. See the following illustration:

bSwap value when nCellIndex = 2 and nTargetIndex = 6

Cell order:1 2 3 ... 4 5 6

TRUE

1 6 3 4 5 2

FALSE

1 3 4 5 6 2

Example

This function shuffles the order of the cells

L_LTIVWTEX_API  L_INT DispContainerRepositionCellExample(HDISPCONTAINER hCon) 
{ 
   L_INT nRet; 
   L_INT nI, nCount; 
   // Get Cells Count 
   nCount = L_DispContainerGetCellCount (hCon, 0); 
   srand((L_INT)GetCurrentTime()); 
   // Shuffles all the cells 
   for (nI = 0; nI < nCount; nI++) 
   { 
      nRet = L_DispContainerRepositionCell(hCon, nI, (rand() % nCount),TRUE, 0); 
      if(nRet != SUCCESS) 
         return nRet; 
   } 
   return SUCCESS; 
}
