I tried your code on Ubuntu and it looks nice; good job! Two minor
comments:

      * It was a bit tedious to compile as I had to manually fix the
        include and link flags. If I removed LIBS and INCLUDEPATH from
        src.pro and instead added, 

                INCFLAGS = $$system(mkoctfile -p INCFLAGS)
                LFLAGS = $$system(mkoctfile -p LFLAGS)
                LIBS    += $$LFLAGS -loctave -loctinterp
                QMAKE_CXXFLAGS  += $$INCFLAGS
        
        things got picked up automatically. I don't know if this works
        on other platforms, though...

      * I see issues due to localisation. If I start 'octavede' with
        LANG="da_DK.utf8" (default on my system), 'plot (1:10)' does not
        work with the gnuplot backend. If I reset LANG to "" or "C" then
        it works just fine (this issue is due to the commas and periods
        in numbers are used opposite in Danish compared to English). I
        don't know if you can disable localisation in QT; in GTKmm you
        can do it when you initialise GTK.
