#include "ltivw.h"

L_LTIVW_API L_INT L_DispContainerGetCellPosition(hCon, nCellIndex, puRow, puCol, uFlags)

HDISPCONTAINER hCon;	/* handle to the container */
L_INT nCellIndex;	/* index of the cell */
L_UINT * puRow;	/* pointer to a variable to be updated */
L_UINT * 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
hCon	Handle to the container.
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. Pass 0.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

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