LImageViewer::GetCellPosition

#include "ltwrappr.h"

L_INT LImageViewer::GetCellPosition (nCellIndex, puRow, puCol, uFlags);

L_INT nCellIndex;	/* index of a cell */
L_UINT L_FAR * puRow;	/* pointer to a variable to be updated */
L_UINT L_FAR * puCol;	/* pointer to a variable to be updated */
L_UINT uFlags;	/* reserved for future use */

Retrieves the column and row number for the cell with the specified index. This function is available only in the Medical Imaging Suite toolkits.

Parameter	Description
nCellIndex	A zero-based index of the cell for which to get the position.
PuRow	Pointer to a variable to be updated with the vertical position (row) of the specified cell. Row numbering starts with 1.
puCol	Pointer to a variable to be updated with the horizontal position (column) of the specified cell. Column numbering starts with 1.
uFlags	Reserved for future use. Must be zero.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. To get extended error information, call GetLastError, and refer to Return Codes.

Comments

The row and column numbers obtained by this function are relative to the first cell in the container.

Example

// This function scrolls down or up in order to make the cell become visible
void GetCellPositionExample(LImageViewer& ImageViewer)
{
   L_INT nCellIndex = 0 ;
   L_INT nCount;
   L_UINT uRow;
   L_UINT uCol;
   L_UINT nRet;
   DISPCONTAINERPROPERTIES DispContainerProp;

   // Get Cells Count
   nCount = ImageViewer.GetCellCount(0);

   if ((nCellIndex < 0) || (nCellIndex >= nCount))
      return;

   // get the row count of the container
   DispContainerProp.uStructSize = sizeof(DISPCONTAINERPROPERTIES);
   DispContainerProp.uMask = DCPF_NUMROWS;
   nRet = ImageViewer.GetProperties(&DispContainerProp, 0);

   // get the row and the col position
   nRet = ImageViewer.GetCellPosition(nCellIndex, &uRow, &uCol, 0);

   nRet = ImageViewer.SetFirstVisibleRow(max(0, ((L_INT)uRow - (L_INT)DispContainerProp.uNumRows + 1)), 0);
