Java SE (Java Platform, Standard Edition)

Hi,

I have a top level window called mainFrame that has buttons called "Start", "Stop", and "Pause".

I want the pause button to pause a Depth First Search thread called Search.DFS() and then resume when the "Start" button is pressed again.

I read the example at http://forums.sun.com/thread.jspa?forumID=54&threadID=5240475 is this the correct way of doing this?

    private void startButtonActionPerformed(java.awt.event.ActionEvent evt) {                                     
        stopButton.setEnabled(true);
        if (startButton.getText().equals("Start")) {
            startButton.setText("Pause");
            search = new Search(this); // start search
        } else {
            startButton.setText("Start");
            // insert code to pause here... I'm not sure how to do this yet...
            //search.pause();
        }
    }                                           

    private void stopButtonActionPerformed(java.awt.event.ActionEvent evt) {                                           
        stopButton.setEnabled(false);
        startButton.setEnabled(true);
        startButton.setText("Start");
        //search.stopme();
    }    

Then inside my Search class/thread I have the following code... that has access to mainFrame my top level window...

public class Search extends Thread {

    TopLevel mainFrame;

    public Search(JavaSpiderView mFrame) {
        super("Search Thread");
        mainFrame = mFrame;
        start();
    }

    public void run() {
        setup();
        DFS();
    }

    public void pause() {
        
    }
    

    public void stopme () {
        
    }

    public void DFS() {
        // depth first search code this takes a long time I want the user to be able to pause or stop this.
        }
        return;
    }

}

I would like to create two new methods inside my Search class one called search.pause() and another called search.stopme() that I can call from my mainFrame.

Any ideas?

Thanks,
V$h3r
