setShrinkToFit using POI

I am trying to implement setShrinkToFit function using jakarta POI Package, for setting a particular cell in MS Excel to have the property setShrinkToFit to be checked as true.

import org.apache.poi.hssf.usermodel.HSSFCellStyle;
import org.apache.poi.hssf.record.ExtendedFormatRecord;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFCell;
import java.io.IOException;
import java.io.FileOutputStream;

public class TestHSSFCellStyle extends HSSFCellStyle {

TestHSSFCellStyle(ExtendedFormatRecord e) {

super((short) 0, e);


public static void main(String[] args) throws IOException {

HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet sheet = wb.createSheet("format sheet");

ExtendedFormatRecord e = new ExtendedFormatRecord();


TestHSSFCellStyle t1 = new TestHSSFCellStyle(e);
HSSFRow row = sheet.createRow((short)0);
HSSFCell cell = row.createCell((short)0);

FileOutputStream fileOut =
new FileOutputStream("workbookTest.xls");


But, I am not able to set the property. Kindly help me to proceed the same.

I don't really have an answer, but the javadocs says about the constructor you're using:

protected HSSFCellStyle (short index, ExtendedFormatRecord rec)
Creates new HSSFCellStyle why would you want to do this??

That might be worth thinking about. Since all the other ExtendedFormatRecord options are accessible through HSSFCellStyle, maybe setShrinkToFit isn't implemented?

I'm also not quite clear on what 'index' is; are you sure that 0 is an appropriate value?
That which doesn't kill us makes us stronger. I think a piece of pie wouldn't kill me. Tiny ad:
Java file APIs (DOC, XLS, PDF, and many more)
