JFileChooser - adjust columns width

Question

I've JFileChooser:

public static JFileChooser bakFileChooser() {
    JFileChooser fileChooser = new JFileChooser();
    fileChooser.setDialogTitle("Vyber BAK soubor");
    if (dataSource.equalsIgnoreCase(localdbInstanceName)) {
        fileChooser.setCurrentDirectory(new File(localdbDataPath));
    }
    else {
        Connection connection = connectionMap.get(dataSource);
        File backupDir = SqlServerBackupManager.getSqlServerBackupDir(connection);
        fileChooser.setCurrentDirectory(backupDir);
    }
    fileChooser.getActionMap().get("viewTypeDetails").actionPerformed(null);
    fileChooser.setFileSelectionMode(JFileChooser.FILES_AND_DIRECTORIES);
    fileChooser.addChoosableFileFilter(new FileNameExtensionFilter("*.bak", "bak"));
    fileChooser.setAcceptAllFileFilterUsed(true);
    fileChooser.setPreferredSize(preferredDimension);    
    return fileChooser;
}

It works fine. The only ugly think is too low column width after directory is opened (or changed). User has to manualy adjust first column width to see full file/dir names.

How can I adjust the column width automaticaly after directory is opened / changed?

Or how to set fixed column width?
