MouseListener

Hello Forum

I am new in java.I am createing a Frame.Which have two label lb1,lb2.

I want to set MouseListener for both label.How can i write plz tell me

Thxs in advance..

First define the mouse listener as follows.

Code:

---

              MouseListener mouseListener = new MouseListener() {
                    public void mouseClicked(MouseEvent e) {
                    }
                    public void mouseEntered(MouseEvent e) {
                    }
                    public void mouseExited(MouseEvent e) {
                    }
                    public void mousePressed(MouseEvent e) {
                    }
                    public void mouseReleased(MouseEvent e) {
                    }
                };

---

Then simply add it to the label (any control).

Did you try on the web, there you can found lots of examples. And also on the suns' web site you can find about How to Write a Mouse Listener

i try to add on this way but how can i add this for two label.I add some more even.Like ActionListener and it is working.

Code:

---

public void actionPerformed(ActionEvent e) {
       
                String actionCmd = e.getActionCommand();
                if (actionCmd.equals("Show File ")) {
                   
                        try {   

                                                File file = new File("");

                                               
                                                       
                                                        String[] cmdArray = {"cmd", "/c", "start", "\"\"", file.getAbsolutePath()};
                                                        Runtime.getRuntime().exec(cmdArray);



                                            }
                                                  catch (Exception x)
                                                  {
                                                    x.printStackTrace();
                                                 
                                            }
                }


               
               
                        else if (actionCmd.equals("Help Topics"))
                        {
                                try {   

                                        File file = new File("chm.chm");

                                       
                                               
                                                String[] cmdArray = {"cmd", "/c", "start", "\"\"", file.getAbsolutePath()};
                                                Runtime.getRuntime().exec(cmdArray);



                                    }
                                          catch (Exception x)
                                          {
                                            x.printStackTrace();
                                         
                                    }

Plz help me any one..


Thx's in Advance..

In simple way to solve this is implement two mouse listeners and add them to two labels. So you can implement different functionality there.

                            if(clicked==two)
                          {
                            }

Actually Mir, what your code doing is, get the click label event and depend on that do the processing. In that way you need only one mouse listener.
