Your code should look like this:

double step = 1.0 / data->size();
progress_bar->set_fraction( 0.0 );

for ( iter = data->begin(); iter != data->end(); ++iter )
{
   row = *( base_ptr->append() );
   row[base_table.column_value] = iter->first;
   row[base_table.column_id] = iter->second;
	
   double new_val = progress_bar->get_fraction() + step;
   if( new_val > 1.0 )
      new_val = 1.0;
	
   progress_bar->set_fraction( new_val );

   while(Gtk::Main::events_pending())	// this allows your
      Gtk::Main::iteration();		// GUI to update your
}					// progress bar

Hope this helps.
