Bug #52699 has been fixed so it is okay to proceed with this bug.

For the moment, ginput on the dev branch does not work (see bug #52699). I guess that needs to be fixed first before work can proceed on this bug.

gnuplot has a MOUSE_X, MOUSE_Y variable for reporting mouse position, and there does appear to be use of these variables in the script file _gnuplot_ginput_.m.

However, I can't seem to get any ginput() to work in the recent development code, regardless of toolkit. So, it is difficult for me to investigate.

As suggested in the last comment, the bug only appears with gnuplot, I've tested with the 4.0.0 version and using fltk it works but using gnuplot no.

I can confirm that ginput doesn't work for me with gnuplot toolkit (I tested x11, qt and wxt terminals) in Octave 4.2.1

Changing category and title to make it clear that the issue is gnuplot specific.

The fltk graphics_toolkit is not available for octave-4.2.1 but it is for the version 4.0.0, the only one toolkit available for the 4.2.1 version is gnuplot.

To be utterly explicit, does this work?

As reported in bug #51452, it is a known issue that ginput only works with Qt toolkit if no tool (zoom-in, zoom-out, pan, text) is enabled in the figure. Is this what you are observing or does ginput really never work?

Also, is the issue you are reporting only present for Qt toolkit (the default, at least in --no-gui mode, not in -cli) or does it also occur with fltk and gnuplot toolkits?

Hello everyone, I remark that for the new version of octave (4.2.1) the ginput doesn't work.
It open the plotting window but then it does not record any points, even with ginput(n) call.
I also tried the RET key but nothing ...
I don't have any warning or error in the cmd (only tried with the octave-cli since octave have troubleshoot with gtk i guess..)
Note : The function works correctly with Octave v4.0.0
