Sets the position of the specified cell, based on the index of the cell.
L_INT LImageViewer::RepositionCell (nCellIndex, nTargetIndex, bSwap, uFlags);
A zero-based index of the cell for which to set the position.
A zero-based index of the new cell position.
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:
|TRUE||Swap the cells.|
|FALSE||Shift the cells.|
Reserved for future use. Pass 0.
|SUCCESS||The function was successful.|
|< 1||An error occurred. To get extended error information, call GetLastError, and refer to Return Codes.|
The row and column numbers obtained by this function are relative to the first cell in the container.
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|
The following function shuffles the order of the cells:
L_INT LImageViewer_RepositionCellExample(LImageViewer& ImageViewer)
L_INT nI, nCount;
// Get the Cell Count
nCount = ImageViewer.GetCellCount(0) ;
// Shuffle all the cells
for (nI = 0; nI < nCount; nI++)
nRet = ImageViewer.RepositionCell(nI, (rand() % nCount), 0, 0);
if(nRet != SUCCESS)
