In my application I use a Default button. I want it to react when ENTER
Key is released. Not when ENTER
Key is pressed.
I removed the KeyStroke
from InputMap
of the button. But it didn't work for me. How should i do that?
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
public class ButtonTest {
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
buildFrame();
}
});
}
private static void buildFrame() {
JFrame f = new JFrame("Test");
f.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
JButton button = new JButton(new AbstractAction("Button") {
@Override
public void actionPerformed(ActionEvent e) {
System.out.println("ButtonTest::actionPerformed: CALLED");
}
});
JButton button2 = new JButton("Button 2");
InputMap im = button.getInputMap();
im.put(KeyStroke.getKeyStroke("ENTER"), "none");
im.put(KeyStroke.getKeyStroke("released ENTER"), "released");
f.setLayout(new GridBagLayout());
f.add(button);
f.add(button2);
f.getRootPane().setDefaultButton(button);
f.pack();
f.setLocationRelativeTo(null);
f.setVisible(true);
}
}
This is the sample code.
JRootPane rootPane = SwingUtilities.getRootPane(/* Your JButton */);
rootPane.setDefaultButton(/* Your JButton */);
