Hi all,
I have a swing application, with some buttons. User can move the focus using tab key. When a focus is on a button and if the user hits enter key, it is not invoking the click action of the button. But when I press space key it is working. But the same application is working fine in Windows.
What could be the problem?
Thanks.
try this:
button.addKeyListener(new KeyAdapter() {
public void keyReleased(KeyEvent ke) {
if (ke.getKeyCode() == KeyEvent.VK_ENTER) {
// perform your operation here...
}
}
});
@sun_shail :
thanks for your suggestion.. but i afraid that's not a solution..!
reason:
none of the buttons in the entire application is responding to enter keys..
we have tons of button and I cannot add listener to each and every one of them ;((
This problem happens only in linux, its working fine in windows and solaris.
linx version is red hat linux enterprise eiditon..
suggestions?
Hi boss,
You can do one thing... add the following class in your project and replace JButton word with MyButton in all your classes which uses JButton...
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import javax.swing.Action;
import javax.swing.Icon;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JOptionPane;
public class MyButton extends JButton implements KeyListener {
private static final long serialVersionUID = 1;
public static void main(String shail[]) {
final JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLayout(new FlowLayout());
MyButton button = new MyButton();
button.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
JOptionPane.showMessageDialog(null, "Yes");
}
});
frame.add(button);
frame.setBounds(100, 100, 800, 600);
frame.setVisible(true);
}
public MyButton() {
this.addKeyListener(this);
}
public MyButton(Action arg0) {
super(arg0);
this.addKeyListener(this);
}
public MyButton(Icon arg0) {
super(arg0);
this.addKeyListener(this);
}
public MyButton(String arg0) {
super(arg0);
this.addKeyListener(this);
}
public MyButton(String arg0, Icon arg1) {
super(arg0, arg1);
this.addKeyListener(this);
}
public void keyPressed(KeyEvent arg0) {
}
public void keyReleased(KeyEvent ke) {
if (ke.getKeyCode() == KeyEvent.VK_ENTER) {
this.fireActionPerformed(new ActionEvent(ke.getSource(),
ke.getID(), this.getText()));
}
}
public void keyTyped(KeyEvent arg0) {
}
}
let me know if it works... OK ... enjoy...
