octave: menus on figure windows not responsive

octave: menus on figure windows not responsive

[Alan Barnett]

I'm running octave 3.8.1, emacs 24.3.50.2, and Ubuntu 24.04.
I loaded the latest version of octave.el.
I am able to run octave from emacs as an inferior process using the 
run-octave command.

I have a problem with the graphics.  When I use the "plot" command, a 
window opens and the plot appears correctly,  The problem is that 
neither pulldown menus on the plot window nor the "x", "minimize", and 
"fullscreen" buttons in the upper right of the window frame are 
sensitive.  I therefore cannot close the window.
I can move and resize the window using the mouse, but when I resize the 
window, the plot size doesn't change.
In addition, I cannot open more than one window at a time;  if I use the 
"figure" command to open a new plot window, the old one closes.

Has anyone else noticed this bug?  Is there a fix?

Could you try start emacs with -q or -Q and then load the latest
octave.el to see if this happens again? If yes, please report it by M-x
report-emacs-bug. Thanks.

24.3.50 is an old development version of what became Emacs 24.4.
There is no reason to run that instead of the actual Emacs 24.4 release.

bug#19723: 24.4; octave.el; graphics window behaves incorrectly

[Alan Barnett]

When I ran emacs and typed

M-x run-octave

emacs opened a buffer called *Inferior octave*
with octave running.

I then issued the octave plot command:
octave>plot(1:100)

The plot window appeared, but the pull-down menus, the buttons at the
bottom, and the close (x) button did not respond to mouse clicks.

The minimize button worked correctly.
The full-screen toggle button worked, but was buggy.
When I pushed the full-screen toggle button, the plot window did expand,
but the plot remained the same size and the menu bar and bottom buttons
were not displayed.
Manually changing the plot window size with the mouse resulted in the
same behavior.

The octave plot window behaves correctly when octave is run from a
console instead of from emacs.

This might have something to do with how octave plotting window uses
something like readline event loop or some such.

See inferior-octave-startup-args and mess with it. I seem to recall
removing --no-line-editing might help but it might cause problems
somewhere else.

HTH,

(I'm going through old bug reports that unfortunately got little
response at the time.)

I'm able to reproduce this in Emacs 28...  but it turns out that I can
reproduce this on the command line as well by using the -i switch:

$ octave -i
...
octave:1> plot(1:100)
octave:2> 

will display the same symptoms.  So I don't think this is an Emacs
bug -- it has to be an Octave bug, and should be reported to the Octave
maintainers.

So I'm closing this bug in the Emacs bug tracker.
