How to set symbol to QwtLegendLabel

[lin3398032]

Hi Uwe,

I migrated my project from Qwt 5.0 to Qwt 6.0. I found that QwtLegendItem was replaced by QwtLegendLabel in Qwt 6.0.

But there is no setSymbol() in QwtLegendLabel. How can I set symbol for QwtLegendLabel?

My original code is like below:

QwtLegendItem *item = new QwtLegendItem(this);
item->setSymbol(...);

QwtLegendItem *item = new QwtLegendItem(this);
item->setSymbol(...);

To copy to clipboard, switch view to plain text mode 

And how to set curvePen() for QwtLegendLabel?

Thanks a lot!!
