QwtPlot layers?

I am currently using QwtPlot with multiple axes and multiple curves. Every curve can have one or more QwtPlotZoneItem meaning that some samples of curve are invalid. But unfortunately some of these zones will be on top of some curves and some won't. I want to have 2 layer groups - curves and plotZones, so first will be all curve layers and then above all of them will be layer group with zones. How can I achieve that if I can't attach these items in this order?

Hello,

looks like you are looking for setting the QwtPlotItem z-order. See http://qwt.sourceforge.net/class_qwt...89c71b3a643e82. Both QwtPlotCurve and QwtPlotZoneItem are derived from QwtPlotItem.
