About QwtPlotRenderer with QwtTextLabel

There are some QwtTextLabels on a plot , can i use QwtPlotRenderer to render the labels?

As QwtTextLabel is a widget I guess they are over not on the plot. Then you would have to overload QwtPlotRenderer::renderCanvas() and write some code.
Another option is to use QwtPlotItems instead - f.e QwtPlotMarker or QwtPlotTextLabel.
