Hello
Currently gnuplot qt terminal can be built but does not work.
(I used the cygwin 64 the updated today. The qt5 is used.)
Terminal type set to 'qt'
gnuplot> plot sin(x)
Could not connect to gnuplot_qt "qtgnuplot4488" . Starting a new one
Warning: slow font initialization
I found a post in the gnuplot Nabble archive which realize to the qt terminal of gnuplot 5 to work.
http://gnuplot.10905.n7.nabble.com/Gnuplot-version-5-0-is-now-available-tp19185p19202.htmlThe patch against the qt and the gnuplot in the above post seems to enable gnuplot to work on the cygwin. Can the patch in the post against the qt in the cygwin?
