How do I set font style on Treeview rows independently.

[samsoliz gmail com]

I set the style permanently when adding the columns by doing the following:

       pFileRenderer->property_style() = Pango::STYLE_ITALIC;
        pFileRenderer->property_style_set() = true;

However I want to set the style per rows.  I used the standard way of setting column/cell properties but the does not work using the following:

NOTE:  The following is only showing part of the code.

myclass::append_columns()
{

    Gtk::CellRendererText* pFileRenderer = Gtk::manage( new Gtk::CellRendererText() );
    int cols_count = m_TreeView.append_column("File", *pFileRenderer);
    Gtk::TreeViewColumn* pFileColumn = m_TreeView.get_column(cols_count-1);

    if(pFileColumn)
    {
        pFileColumn->add_attribute(pFileRenderer->property_text(),
                m_writtenColumns.m_col_nFile);
        pFileColumn->add_attribute(pFileRenderer->property_style(),
               m_writtenColumns.m_col_nFontStyle);
        pFileColumn->add_attribute(pFileRenderer->property_style_set(),
               m_writtenColumns.m_col_bStyleSet);
    }
}

myclass::AppendRow(MyObject &object)
{
        iter = m_refListStore->append();
        Gtk::TreeModel::Row row = *iter;

        row[m_writtenColumns.m_col_nFile] = Object.getFileNumber();
        row[m_writtenColumns.m_col_nFontStyle] = Pango::STYLE_ITALIC;
        row[m_writtenColumns.m_col_bStyleSet] = true;
}

Everything compiles clean but does not work.
