L_DispContainerGetCellCount

#include "ltivw.h"

L_LTIVW_API L_INT L_DispContainerGetCellCount(hCon, uFlags)

HDISPCONTAINER hCon;	/* handle to the container */
L_UINT uFlags;	/* reserved for future use */

Returns the number of cells managed by the container.

Parameter	Description
hCon	Handle to the container.
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 L_DispContainerInsertCell. To remove one or more cells from the container, call L_DispContainerRemoveCell.

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.
