Hi,

i use a QwtPlot with a QwtPlotShapeItem...

QPainterPath path;
path.addRect(....);
 
plotShapeItem.setRenderHint(QwtPlotItem::RenderAntialiased, true);
plotShapeItem.setShape(path);
plotShapeItem.setItemAttibute(QwtPlotItem::Legend, true);
plotShapeItem.setLegendMode(QwtPlotShapeItem::LegendShape);
plotShapeItem.setLegendIconSize(QSize(20, 20));
plotShapeItem.setTitle(QString("Winter"));
plotShapeItem.attach(&plot);

QPainterPath path;
path.addRect(....);

plotShapeItem.setRenderHint(QwtPlotItem::RenderAntialiased, true);
plotShapeItem.setShape(path);
plotShapeItem.setItemAttibute(QwtPlotItem::Legend, true);
plotShapeItem.setLegendMode(QwtPlotShapeItem::LegendShape);
plotShapeItem.setLegendIconSize(QSize(20, 20));
plotShapeItem.setTitle(QString("Winter"));
plotShapeItem.attach(&plot);

To copy to clipboard, switch view to plain text mode 

how can i make the legend for plotShapeItem enabled? I dont know how to config the QwtLegend in this case... See here:

I would need the QwtLegendLabel and call setchecked(true)...ideas?

Thanks,
S
