Member QwtPlot::clear ()
    Use QwtPlotDeict::detachItems instead

Class QwtPlotPrintFilter
    In Qwt 5.0 the design of QwtPlot allows/recommends writing individual QwtPlotItems, that are not known to QwtPlotPrintFilter. So this concept is outdated and QwtPlotPrintFilter will be removed/replaced in Qwt 6.x.
