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: |

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.
