Is it possible to get a legend ID using QwtLegend?

[electro300]

I'm sorry to reopen this topic.

I have the same problem but QwtLegendItem doesn't exist now with Qwt 6.1.2! Now we only have QwtPlotLegendItem.

This line is not possible :

((QwtLegendItem*)legendList[i])->identifier().serialNumber();

((QwtLegendItem*)legendList[i])->identifier().serialNumber();

To copy to clipboard, switch view to plain text mode 

I just can do this but it's not ok :

QwtPlotItem *plotItem = plot_spectre->infoToItem( itemInfo );  
    nom_courbe = plotItem->title().text();

QwtPlotItem *plotItem = plot_spectre->infoToItem( itemInfo );  
    nom_courbe = plotItem->title().text();

To copy to clipboard, switch view to plain text mode 

What can i do?

Maybe put the legend with QwtPlotLegendItem but i don't arrive to put on right the legend as :

insertLegend(legend, QwtPlot::RightLegend);

insertLegend(legend, QwtPlot::RightLegend);

To copy to clipboard, switch view to plain text mode 

The legend is inside the plot.
