LImageViewerCell::GetCellBitmapList

#include "ltwrappr.h"

L_INT LImageViewerCell::GetCellBitmapList(phBitmapList, uFlags);

pHBITMAPLIST phBitmapList;	pointer to a variable to be updated
L_UINT uFlags;	reserved for future use

Gets the bitmap list attached to the specified cell.

Parameter	Description
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 the LImageViewerCell::SetCellBitmapList function to set the bitmap list for a cell.
