QwtPlotRenderer and ExternalLegend position

[frankiefrank]

I have a plot that uses a legend positioned initially with QwtPlot::RightLegend and then set to QwtPlot::ExternalLegend.

I want to render the plot to the clipboard but the legend rectangle ends up being painted at position 0,0 and not where I actually see it in my widget.

Here's the rendering code:

QClipboard *clipboard = QApplication::clipboard();
QwtPlotRenderer renderer;
QImage img(this->size(), QImage::Format_ARGB32);
QPainter painter(&img);
renderer.render(this, &painter, this->rect());	
clipboard->setImage(img);

QClipboard *clipboard = QApplication::clipboard();
QwtPlotRenderer renderer;
QImage img(this->size(), QImage::Format_ARGB32);
QPainter painter(&img);
renderer.render(this, &painter, this->rect());	
clipboard->setImage(img);

To copy to clipboard, switch view to plain text mode 

I tried to reposition the legend to QwtPlot::RightLegend but then I naturally get it in the separate right section as you would see it in the widget, which is not what I want.

How can I make the legend rectangle painted in it's actual position?
