Sample code to write a very basic Assistive Technology on GNOME desktop (Sorry! because I have skipped some details…)

Here is a sample Code which can be used to understand how to write Assistive Technology applications:

This application uses swing text entry to enter text in Gedit first text widget….

NewWindow.java

import javax.swing.*;
import javax.swing.event.*;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
 
public class NewWindow extends JFrame {
    /**
     * 
     */
    private static final long serialVersionUID = 1L;
    public JTextArea textArea= new JTextArea();
    public JScrollPane textAreaScrollPane = new JScrollPane(textArea, JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED, JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);
    public JButton button = new JButton("Click me");
    JPanel panel = new JPanel();
 
    public static native void storeandExecuteResult(String result,int length);
   ///*
    static{
            //System.setProperty("java.library.path", "/usr/lib/");
            System.loadLibrary("NewWindowLib");
    }
    /**/
 
    public static void main(String args[]){
        NewWindow newWindow= new NewWindow();
    }
 
    NewWindow(){
        textArea.addCaretListener(new CaretListener() {
            public void caretUpdate(CaretEvent e) {
                String myText=textArea.getText();
                int myTextLength=myText.length();
                storeandExecuteResult(myText,myTextLength);
            }
        });
        button.addActionListener(new ActionListener()
        {
 
            public void actionPerformed(ActionEvent e) {
                storeandExecuteResult("Hello",5);
            }
 
        });
        panel.setLayout(new BoxLayout(panel, BoxLayout.LINE_AXIS));
        panel.add(textAreaScrollPane);
        panel.add(button);
        this.add(panel);
        this.setBounds(100, 100, 200, 200);
        //this.setFocusableWindowState(false);
        this.setEnabled(true);
        this.setAlwaysOnTop(true);
        this.setVisible(true);

Now What ever you will enter in swing text area will also be reflected in Gedit text Area.
