I am crossposting this thread on using a browser with Octave or Matlab (Math tools for EE developer). This is a thread on using javascript and a browser as a Octave UI. --- Very early in the process. - Trying to get a fork, pipe, or async to work in windows.
So far, It's been 3 hours of work.
I'm working on a very limited and different approach to a GUI. Octave is a STDIN and STDOUT focused product. I'd like a functionalized library using browser based java scripting as an alternative. (It's crude in this form, but workable).
I've needed to use a browser as a front end to html GUIs in Octave with Stdin and Stdout for the NMEA2000 project. Both IE (4+) in windows and Firefox support console output. This is based on Gunter Born's wscript page. It stops octave in the process. There is some browser based interaction that would add a lot to Octave.
I'm still working the firefox stuff and linux. The code in form1.html shown below should have a window.close(); to return and close the browser. - No Web Server is used!!! It's all local.
Yes, it's still very crude, but it offers some simple opportunities for easy development of GUI's with forms and browsers. Great for developing a test harness with the Tek 11801C and GPIB with Octave!!!
The below example has been tested to work in Matlab and Octave...
In windows octave, a simple line like the following executes a cscript. (Note system must be lower case in MATLAB 7.1) (I put these in the matlab work directory for MATLAB and the Octave directory for octave - Did not enter paths).
[Status,Output] = system("cscript octave2.js");
The cscript returns the wscript.echo entries from the cscript batch file.
octave2.js
//************************************************
// File: Form1.js (WSH sample in JScript)
// Author: (c) G. Born modified for octave
//
// Using Internet Explorer 4 or 5 to retrieve
// form input
//************************************************
var Text2 = "You entered:\n";
// Launch Internet Explorer, and connect event handler.
var oIE = WScript.CreateObject("InternetExplorer.Application", "IE_");
oIE.Left = 50; // Window position and other properties
oIE.Top = 100;
oIE.Height = 100;
oIE.Width = 280;
oIE.MenuBar = 0; // No menu
oIE.ToolBar = 0;
oIE.StatusBar = 0;
// Commented out because it causes a corrupted window border.
// oIE.Resizable = 0 // Disable resizing.
oIE.navigate(GetPath() + "Form1.htm"); // Load form.
oIE.Visible = 1; // Keep visible.
// Important: Wait until IE is ready.
while (oIE.Busy) {WScript.Sleep(200)} // Suspend
var ready = false; // Form is still open.
// Wait until the user closes the form using
// the Close button in the upper right corner of the window.
// This sets ready to true in the onclose event.
while (!ready) {WScript.Sleep(500)} // Suspend
// Display the data obtained in the event handling procedure.
WScript.Echo(Text2 + "\n" + name + "\n" + age);
// We're ready now. The sample script terminates.
// Here you can add script-specific code.
// Event handler and helper
function IE_OnQuit()
{
// Event handler is called if IE terminates.
// This happens if the user clicks the Close button.
// Retrieve the values.
name = "Name: " + oIE.Document.ValidForm.fName.value;
age = "Age: " + oIE.Document.ValidForm.fAge.value;
ready = true; // Indicate form is closed.
}
function GetPath()
{
// Get script path because form (HTML file)
// must be in the same folder.
var path = WScript.ScriptFullName;
path = path.substr(0, path.lastIndexOf("\\") + 1);
return path;
}
//*** End
and the form form1.htm which returns to the script on the browser close. (Needs a javascript function so use the X to close the window.
<HTML>
<form name="ValidForm">
<p>
Name:
<input type="text" size="5" name="fName">
Age:
<input type="text" size="3" name="fAge">
<br>
Password:
<input type="password" size="12" maxlength="8" name="fPassw">
<input type="button" name="Button1" value="OK">
<br> The OK button needs to be fixed (close the browser instead) and look at the output variable.
<input type="checkbox" name="fPrinter" value="1" checked>
Printer
<input type="checkbox" name="fScreen" value="2">
Screen
<br>
Remarks:
<br>
<textarea cols="40" rows="5" name="fRemark">
</textarea>
</p>
</form>
</HTML>
The Output variable will contain everything from the echoed commands.
Really I need to convert this to a functionalized .m or oct library.
[Status.Response] = browsermodal("exampleform.html", params,...);
Thanks

Hello,
Please pardon me for posting this question since it seems like it's been asked many times before. However, I am quite confused about which options are still valid for a GUI frontend to Octave.
What I'd like to have is something like Octave Workshop (http://www.math.mcgill.ca/loisel/octave-workshop/). However, as that page says, the project is no longer being maintained. There also seems to be something at
https://sourceforge.net/projects/octave-gtk/, but the screen shots there are not very good and it seems like activity has stopped on that project as well. I also saw a number of references to Tcl, JAVA, and Python programs that are in various states of maintenance and functionality. In summary, I'm confused.
Can someone please clarify this issue for me?
