#include "ltwrappr.h"

L_INT LImageViewerCell::GetSubCellTag(nSubCellIndex, uRow, uAlign, pTagInfo, uFlags)

L_INT nSubCellIndex;

/* index into the image list attached to the cell */

L_UINT uRow;

/* row index */

L_UINT uAlign;

/* flag */

DISPCELLTAGINFO * pTagInfo;

/* pointer to a structure */

L_UINT uFlags;

/* reserved for future */

Retrieves the sub-cell tag information.

Parameter

Description

nSubCellIndex

A zero-based index into the image list attached to the cell. This sub-cell contains the image that contains the bitmap region that needs to be retrieved. Pass -2 to refer to the selected sub-cell.

uRow

The number of rows to count before reaching the Sub-cell tag to be retrieved.

uAlign

Value that specifies the origin point from which to count the rows specified in the uRow parameter. For example, if uAlign is DISPWIN_ALIGN_BOTTOMLEFT and uRow is 4, the application will count 4 rows from the bottom and place the tag (overlay text) on that location. Possible values are:

 

Value

pTagInfo

Pointer to the DISPCELLTAGINFODISPCELLTAGINFO structure that contains information about the tag.

uFlags

Reserved for future use. Pass 0.

Returns

SUCCESS

The function was successful.

< 1

An error occurred. Refer to Return Codes.

Comments

If you are planning to retrieve the text, you should allocate enough space to hold the tag text.

This function retrieves the Sub-Cell tag. The sub-cell tag is the tag that appears only on one frame of the cell frames. You can create a sub-cell tag using the LImageViewerCell::SetSubCellTag function. To create a tag that appears on all the frames of the cell, use the LImageViewerCell::SetCellTag function.
