L_DispContainerGetCellBitmapList

#include "ltivw.h"

L_LTIVW_API L_INT L_DispContainerGetCellBitmapList(hCon, nCellIndex, phBitmapList, uFlags)

HDISPCONTAINER hCon;	/* handle to the container */
L_INT nCellIndex;	/* index of a cell */
HBITMAPLIST * phBitmapList;	/* pointer to a variable to be updated */
L_UINT uFlags;	/* reserved for future use */

Gets the bitmap list attached to the specified cell. 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 bitmap list.
phBitmapList	Pointer to the variable to be updated with the cell's bitmap list.
uFlags	Reserved for future use. Pass 0.

Returns

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

Comments

If the cell at the specified index has no image, phBitmapList will be NULL.

Call L_DispContainerSetCellBitmapList to set the bitmap list for a cell.
