Habt ihr eine Idee? Wieso wird "es geht" nicht ausgegeben wenn ich die Pfeiltaste nach unten drücke?
Java:
package inputten;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import javax.swing.*;
import javax.swing.JTextField;
public class InputSelber implements KeyListener {
JFrame frame = new JFrame("Inputten");
JTextField field = new JTextField();
JPanel panel = new JPanel();
public InputSelber() throws IOException{
frame.setBounds(0,0,500,500);
frame.setVisible(true);
frame.setLayout(null);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(panel);
panel.add(field);
panel.setBounds(0,0,500,500);
panel.setLayout(null);
field.setBounds(100,100,200,20);
panel.addKeyListener(this);
// InputStreamReader isr = new InputStreamReader(System.in);
// BufferedReader br = new BufferedReader(isr);
String eingabe = field.getText();
System.out.println(eingabe);
}
public static void main(String[] args) throws IOException {
new InputSelber();
}
@Override
public void keyPressed(KeyEvent e) {
if(e.getKeyCode() == KeyEvent.VK_DOWN){
System.out.println("es geht");
}
}
@Override
public void keyReleased(KeyEvent arg0) {
// TODO Auto-generated method stub
}
@Override
public void keyTyped(KeyEvent arg0) {
// TODO Auto-generated method stub
}
}
