Hallo liebes Forum.
Mit Netbeans lässt sich ein fertiges JFrame machen.
Habe dazu ein Button hinzugefügt womit man das Programm/Fenster schließen können soll.
So sah das fertig aus.
Aber wie oder wo füge ich das nun ein mit dem :
beendenButton.addActionListener(new ActionListener(){
@Override
public void actionPerformed(ActionEvent e)
{
System.exit(0);
}
});
LG
