How to replace QwtLegend::legendItems()

[rock37]

Hey,
i'm on updating from qwt5 to qwt6 and i have a line like:

QList<QWidget *> items = plot->legend()->legendItems();

which is giving me the error message "there is not legendItems() ind QwtAbstractLegend" so i found QwtLegend and changed the line to

QList<QWidget *> items = qobject_cast<QwtLegend*>(plot->legend())->legendWidgets();

but legendWidgets wants a QVariant parameter, what should i do from here and am i right with the legendWidgets() method call ?

@rock37 the hole function looks like:

// XYZ inherits QwtPlot
XYZ * plot = my_plots.constData().at(i);

    if ( plot->legend() )
    {
      QList<QWidget *> items = qobject_cast<QwtLegend*>(plot->legend())->legendWidgets(?????);
      for ( int i = 0; i < items.count(); i++ )
      {
        QwtLegendItem * legend = qobject_cast<QwtLegendItem *>(items [i]);
        QwtText         text   = legend->text();
        QwtText         newText(text);
        newText.setPaintAttribute(QwtText::PaintUsingTextFont, false);
        legend->setText(newText);
      }
    }
    plot_renderer.render(
        plot, &painter, QRect(plot->x(), plot->y(), plot->width(), plot->height())
    );

This post relates to Qwt, which is based on Qt, but it is not Qt. The Qwt mailing list is the right point of contact, I think.

@Axel-Spoerl i have subscriped to the mailing list but i can't find a way to create a new thread.
