Re: Java package: how to get output from a java gui

[vinukn]

import javax.swing.*;
public class MyFrame extends JFrame{
String text;
boolean isOk=false;
JTextField t;
public String getText(){
 if(isOk){ 
   return text;
 else{
   return "No text";
 }
}
public void setText(String text){
 this.text = text;
}
public void create(){
 JFrame f = new JFrame();
JPanel p = new JPanel();
t = new JTextField(20);
JButton b = JButton("OK");

b.addActionListner(new ActionListner(){
  public void actionPerformed(ActionEvent ae){
 setText(t.getText()); 
 isOk = true;
 }
});
p.add(t);
p.add(b);
f.add(p);
f.setvisible(true);
}
 public String octave_out(){
   MyFrame m = new MyFrame();
  m.create();
  return m.getText();
}
}// end of code

I made a jar called myjar.jar. Then from octave terminal I create an object
pkg load java;
ob=javaObject('MyFrame');
ob.octave_out()

octave displayed gui and return a text "No text". Gui does not wait for user
input.
