How to detect function key (like F1,F2,...etc)

[Dylan]

Dear all

I used following Java code to get key from keyboard, however this function
KeyEvent.getKeyCode() can not detect any function (like F1,F2,...etc). Could
you give me a hand on this case. Thanks for your help. ^^


import java.awt.*;
import java.awt.event.*;

public class keyEventTest extends Frame implements KeyListener {
//«Øºc¤l
keyEventTest() { super(); }
keyEventTest(String title) { super(title); }

public static void main(String[] arg) {
keyEventTest keyScreen = new keyEventTest("This is a test Frame");
TextArea ta = new TextArea();
Button bt = new Button("Button");

keyScreen.setLayout(new BorderLayout());
keyScreen.add(ta);
keyScreen.add(bt,BorderLayout.SOUTH);
ta.addKeyListener(new keyEventTest());
keyScreen.setLocation(100,100);
keyScreen.setSize(500,500);
keyScreen.setVisible(true);
}

//Impletement keyListener's method
public void keyPressed(KeyEvent e) {}
public void keyReleased(KeyEvent e) {}
public void keyTyped(KeyEvent e) {
e.getKeyCode();
}
}

Hi Dylan,

just put the e.getKeyCode() method in:
public void keyPressed( KeyEvent e ){;}

this way you will get your int keycodes.
