jTextField 当里面输入的文字改变时激发事件

Question

jTextField 当里面输入的文字改变时我要激发一个事件，在NetBeans IDE 6.5中是哪个事件啊？？？？

Answer 1

jTextField1.getDocument().addDocumentListener(new DocumentListener(){

public void insertUpdate(DocumentEvent e) {
// throw new UnsupportedOperationException("Not supported yet.");
// System.out.print("1");
System.out.println(jTextField1.getText());
}

public void removeUpdate(DocumentEvent e) {
// throw new UnsupportedOperationException("Not supported yet.");
// System.out.print("2");
System.out.println(jTextField1.getText());
}

public void changedUpdate(DocumentEvent e) {
//JOptionPane.showMessageDialog(null, "请填写完整！");
System.out.println(jTextField1.getText());
}
});
