Drawing border of item in the QwtPlotLegendItem

Hello,

I am searching how to draw the border of the little square representing a curve or histogram int the QwtPlotLegendItem.
In the picture below, the histogram with blue pen but with no brush is not represented in the legend ("intensité"). I want a square with blue border ...
Any idea ?

You can overload QwtPlotItem::legendIcon() for your curves/histograms.
