[SOLVED] Swing Timer issue

[Doctor Cactus]

Hi, is there any alternative to using Thread.sleep() to wait a certain amount of seconds within a swing timer? The program is not responsive at times using Thread.sleep(). I have heard its a bad idea with a GUI. I have posted code below.

Help is greatly appreciated.



javax.swing.Timer timer = new javax.swing.Timer(1000, new MyTimerActionListener());

timer.start();

try
{
Thread.sleep(8000);
}
catch (InterruptedException e)
{
}
timer.stop();



import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class MyTimerActionListener implements ActionListener
{
public void actionPerformed(ActionEvent e)
{



}
}

Not only is it a "bad idea", you shouldn't use thread.sleep at all in a GUI on the EDT code as it will only serve to put your app to sleep. Why not use a timer itself? That's what it's for after all.

If this doesn't help, then please give more information on just what exactly the program is supposed to be doing. Good luck.

Ok, so as you can see in the example I posted, all I want to do is wait a number of seconds. So,for example, how can I wait 8 seconds without using thread.sleep()?

I have looked at the tutorial, but it didn't help. I just want the program to do nothing for x number of seconds. How do I do this?

Timer#setInitialDelay, as you could have easily found out by going through the API.

And just looking at a tutorial is rarely useful, you need to actually do the exercises.

Thanks for the replies. I have found a way to do exactly what I want.
Cheers.
