将actionListener（）添加到JPanel时遇到问题

Question

I am trying to add actionListener to a JPanel in swing frame. I want to create an event when clicking on that particular JPanel. Here is some slice of code where in stuck down.

JLabel jlab=new JLabel("");
JPanel pnl=new JPanel();
pnl.add(jlab);
JPanel mainpnl=new JPanel();
pnl.addActionListener(new ActionListener(){public void actionPerformed(ActionEvent ae)      {jlab.setText("Clciking !!!");}});
mainpnl.add(pnl);

Answer 1

JPanel doesn't have the capabilities to raise ActionEvent s, thus it does not have the method addActionListener .

Instead, you probably want to use a MouseListener instead
