LImageViewer::GetCellCount

#include "ltwrappr.h"

L_INT LImageViewer::GetCellCount(uFlags);

L_UINT uFlags;

/* reserved for future use */

Returns the number of cells managed by the container.

Parameter	Description
uFlags	Reserved for future use. Pass 0.

Returns

>= 0	The number of cells managed by the container.
< 0	An error occurred. Refer to Return Codes.

Comments

To add cells to the container, call LImageViewer::InsertCell. To remove one or more cells from the container, call LImageViewer::RemoveCell.

Please note that the maximum number of rows that a container can have is 4 and the maximum number of columns is 8. However, the number of cells that can be added to a container is limited only by the available memory.
