#1483 gnuplot --persist qith QT no mousing

[sgasp]

when terminal used is qt and -persist option is used there is no mousing

reproduced on ubuntu 12.04 LTS with gnuplot 4.6.1
reproduced on OS X 10.9.4 with default gnuplot install from macports, 4.6.2.

here is a simple way to reproduce it.

$ GNUTERM=qt gnuplot --persist << EOF
>plot sin(x)
>EOF
sgaspari@tllab221:~$

If -persist option is not used, then the mousing is working fine.
The example below allow to use the mouse to scrool, zoom, etc...

$ GNUTERM=qt gnuplot

Here is the documentation on "persist":

gnuplot> help persist

 Many gnuplot terminals (aqua, pm, qt, x11, windows, wxt, ...) open separate 
 display windows on the screen into which plots are drawn.  The `persist` option 
 tells gnuplot to leave these windows open when the main program exits.
 It has no effect on non-interactive terminal output.
 For example if you issue the command

      gnuplot -persist -e 'plot [-5:5] sinh(x)'

 gnuplot will open a display window, draw the plot into it, and then exit,
 leaving the display window containing the plot on the screen.  Depending on
 the terminal type, some mousing operations may still be possible in the
 persistent window.  However operations like zoom/unzoom that require redrawing
 the plot are generally not possible because the main program has already exited.

In other words, the behaviour you describe is exactly what you should expect from "persist". No zoom, no scroll, no toggline log-scale, no anything that requires recalculating and redrawing the plot. "persist" basically just leaves the last plot showing on the screen after gnuplot exits.

I think what you want is not "persist", but this:

      $  gnuplot -e 'plot [-5:5] sinh(x); pause mouse close' &

That leaves gnuplot running in the background so it can manage the display and respond to events that require recalculating the plot.

This question has come up several times recently, so maybe it belongs in the FAQ.

Ok, It is à RTFM question.

wxt terminal supports mousing with -persist option on window and Linux.
