我在试着写一个聊天程序，在JTextArea上输入信息之后，按ctrl+enter组合键就调用别的方法发送出信息；我如何监听组合键被按下？JTextArea上又不能用ActionListener.
是应该用KeyListener吗？我试了半天没搞出来，请高手给出代码。

这段代码能够实现

public class Test {
private boolean isPressed = false;
public void show(){
JFrame frame = new JFrame();

MyTableModel tableModel=new MyTableModel();
JTable table=new JTable(tableModel);
JTextArea text = new JTextArea(3,20);
text.addKeyListener(new KeyAdapter(){
public void keyPressed(KeyEvent e) {
if(KeyEvent.VK_CONTROL == e.getKeyCode()){
isPressed = true;
}
if(e.getKeyCode() == KeyEvent.VK_ENTER && isPressed){
JOptionPane.showMessageDialog(null,"Ctrl+Enter was pressed.");
}
}
public void keyReleased(KeyEvent e){
System.out.println(e.getKeyCode());
if(KeyEvent.VK_CONTROL == e.getKeyCode() || KeyEvent.VK_ENTER == e.getKeyCode()){
isPressed = false;
}
}
});
frame.getContentPane().add(new JScrollPane(text));
frame.setSize(300,400);
frame.show();
}
public static void main(String[] args){
Test test = new Test();
test.show();
}
}
