    Question Place Plot marks on mouse click event

    Hello!

    I want to place some text marks on my plot, upon mouse click. Like in gnuplot.
    I disable zoom & pan by some button, and on pressing other button I want to click on a plot and place a mark on it.

    How can i implement this?

    There is no MouseEvents in QwtPlotMarker, and in the QwtPlot

    Use a QwtPlotPicker in PointSelection mode and connect its selected() signal to a slot, where you insert your markers.
