If I write:

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

it changes the legend's items organization(n columns) but this doesn t solve 
my problem. I would like to know how change the legend's items organization of 
a legend already created, or , if I have to insert a new legend every time I 
want to change the internal organization of the legend
