How do you stop this particular timer? JAVA

randomx · 07-23-2004, 11:07 PM

This timer triggers a progress bar. The goal is to stop the timer (and therefore the progress bar) when a label changes its text.

However, the timer goes on for ages and the progress bar keeps going until it reaches 100%. The timer never stops, it just that the progress bar can't go any further.

In other words,

1. How do you stop the timer below?

2. How do you make this timer below to listen to other events such as threads terminated or label text change?

Feel free to tweak around the code below so I can see what you mean. I learn by example.

Thanks in advance,

Code:

  int i = 0 ;
  public void timer2 ()
  {

    Timer t2 = new Timer ( 10000, new ActionListener () //10 seconds
    {

      public void actionPerformed ( ActionEvent event )
      {

        progressBar.setValue ( i ) ;
        progressBar.setStringPainted ( true ) ;
        i++ ;

      }

    } ) ;
    t2.start () ;
  
    if ( lblStatus.getText ().equals ( "CD succesfully created" ) ) {
      i = 100 ;
      progressBar.setValue ( i ) ;
      progressBar.setStringPainted ( true ) ;
      t2.stop () ;
    }

  }

Is your label already set to "CD succesfully created" (typo here) when you start the timer ?

No, it isn't. The label is by default set to "status".

Then when the thread that burns the CD is all done, it changes the label from "status" to "CD succesfully created".

The thread executes ok, the thread finishes ok, and the label displays "CD succesfully created" ok.

However, the timer doesn't "see" the label I guess.

Any ideas?

You check the label only once, and at a time when its value is "status", so it always fails.
You should do you test periodically to give it a chance !

PS: succesfully should be spelled successfully

That also apears to be the issue to me. After you start the timer you check the label then the thread timer2 completes, while the t2 thread continues to execute. Try setting up a 2nd timer or thread to check the label, and then stop itself and the other thread when it is done.
