Great job on the build, how ever I can having the following errors. the first one complains about the path. but it does seem to work after that.

then it keeps complaining that

_ide_reload_variables_list' undefined near line 5 column 1

warning: mark_as_command is obsolete and will be removed from a future version
of Octave

hi, i had to copy mingwm10.dll from an older installation to run qtoctave.exe

I’m getting lots of errors, all related to Octave scripts.

First, in the Command Prompt window,
[PkgBind::loadCommandList] ‘..\share\qtoctave\pkg-commands.list’ can not be loaded

Then, within QtOctave itself, lots and lots of errors like these every time I enter a command:
error: `int2str’ undefined near line 10 column 36
error: evaluating argument list element number 1
error: evaluating argument list element number 1

Is it possible pkg-commands.list contains the definitions of int2str & other erroring functions? (I tried to find pkg-commands.list so I could test my theory, but it doesn’t seem to be included in this release or the 0.6.8 release)

Thanks for the Windows build!

mfn :

Can you give me a short list fo steps to reproduce the bug?

Sure, no problem.

* Download your Win32 0.9.1 build (the bugfix build) and extract it to a folder
* Download Octave (I got version 3.2.4), install it, copy the files from Octave\bin to QtOctave\bin (there were a couple of duplicate DLL files; I left the originals intact)
* Run QtOctave
* A Command Prompt window will show up; it contains the first error I mentioned
* Execute any command in QtOctave (I did 4+5)
* A plethora of error messages show up (the ones I mentioned)

Would a screen video be helpful?

Selecting “Help of Octave” from the Help menu was not working for me. I got it to work by modifying the qtinfo.m file in the qtoctave/share/qtoctave/scripts_octave directory.
The new version is:

function qtinfo()
prefix = “cmd /c c:/Octave/qtoctave/bin/”;
command=sprintf(“qtinfo %s > nul”, info_file);
printf(“Starting info: %s\n”, command);
system([prefix command], 1, “async”);
endfunction

Depending on where you installed qtoctave you may need to modify the directory path to the qtinfo.exe file in the “prefix” variable.

Hello,
nice program.
Anyway when the editor creates a new variable without echo on the terminal, this is not shown on the “Local user variables” until the variable is not recalled on the terminal or a who command is executed.

I tried your QtOctave 0.9.1.3 with octave-forge packages on octave-3.2.4 mingw32. I have a problem with graphs : the gnuplot windows is behind QtOctave and when I move QtOctave I cannot see the graph. I tried easyplot but it does not work. What can I do ?
Thank you.

Hi,
I also wanted to use easyplot and it didnt work. Any idea what I could do? Below is what i got so far.
Sunny regards,

@12 I have a little experience putting together Nullsoft installers using HM NIS Edit to generate the initial template. I agree that simplifying the installation process would really help make the system more popular.

I’ve been using Scilab with good results; the only problem is the graphs are aliased and unnecessarily ugly. Scilab’s editor is very nice however. Conversely, Octave’s plot engine is Gnuplot which produces very nice output, but Octave’s default console input is harder to use.

Great work – Thanks!!

The png-style icon that comes with it won’t work as an icon. I created an icon that will work out of it. How can I upload it?

Cheers

Hi,

Is this project dead???

Best regards

I’ve never seen this as a seperate project. I just built qtoctave for Windows.

I have been using QtOctave for a while and think it is a great program – the best front end for Octave. However there are some things that would make it much easier to use and efficient. Here are my suggestions for improvements (in order of importance):

Copy, cut, paste between the terminal window, Command line >> bar and the editor with Ctrl C, Ctrl X, Ctrl V and not only with right click
Do not resize the Editor (make narrower) when restarting program or switching terminal window items. (workaround: unmaxemize terminal, then make the terminal wider)
Quicker viewing of large arrays with the spreadsheet viewer
Shortcuts keys for comment/uncomment and indent/unindent
Opening variables in Navigator window (in tabs) and not terminal, as an option
In variable editor, option to select another variable (to display its values without opening it from the Variables list, resizing and positioning the window, etc)
Gnuplot not freezing (hourglass) every time you click on the window title bar, maxemize, close box, etc (probably unrelated to QtOctave).
Show values of variables that aren’t arrays in Variables’ list, such as cell arrays, strings, structures
Allow esc to clear the command line
Ability to change all font sizes (even octave functions) in editor
Allow viewing of variables with data types such as strings, structures, etc.
When you select text in editor and drag it, it runs that piece of code and deletes it. Fix this
Maximize octave terminal on program startup, if it was previously maximized

I would be very grateful to anyone who could implement any of the above!

BTW, I am using Windows XP SP3

The error, where Gnuplot hangs is related to the oct2mat package of OctaveForge. It is easily fixed, as described here under “additional notes” section:

http://wiki.octave.org/wiki.pl?OctaveForWindows

short version:

Run from octave prompt either directly or from within QtOctave:
“pkg rebuild -noauto oct2mat”

Restart QtOctave. After this, plotting should work as usual.

Sorry I forgot the expample:

x=-2:2
y=x.^2
plot(x,y)

easy enough

Thanks again for your fast replies.

I tried your proposal, but easy_plot doesn’t want to work.
Allways 2 windows are coming up, one blocked, both empty.

gnuplot is working now for me without any problem.

If I have some time I try to debug the problem as I can compile the source.

Thanks so far.
