change position of the legend's items

[Gabriel <gab...@ho...>]

Hello

     Im trying to change the position of the legend. To do it, I write:

               QwtPlotLayout *layout = plot->plotLayout();
               layout->setLegendPosition(pos);

   This change the position of the legend, but I would like change the 
internal organization (legend's items organization). When I change the 
position of the legend to Bottom or Top, the legend's items stay with the same 
organtization than before, that is to say, with one column and they don't 
change to a multiple column organization

The legend is created as follows:

            plot->insertLegend(new QwtLegend(), QwtPlot::RightLegend);

Maybe, I have to create it in another way, but i don ´t know how


Thank you
