I am crossposting this on using a browser. It's 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. 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. I still support your scheme, but 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.
Yes, it's still very crude, but it offers some simple opportunities for easy development of GUI's with forms and browsers.
The below example should work...
In windows octave, a simple line like the following executes a cscript.
[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>
<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.

Hello,
Please pardon mme for posting this question since it seems like it's been asked many times before. However, I am quite confised 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 screenshots there are not very good and it seems like activity has stopped on that project as well. I also saw a number o references to Tcl, JAVA, and Python programs that are in various states of maintenance and functionality. In summary, I'm confused.
Can someone please calrify this issue for me?
