Timeline play button

Question

I'm making an animation program, and I'm having problems making the play button and the stop button. I have a slider bar that calls the interpolate function which does most of the work. What I need to do, is simply have a way to increment the slider bar value at a certain rate, like 10 frames per second to make the animation move, or play. I can't just have it loop once, as I need to be able to stop it with the stop button. I have looked at timers, but don't know how I could accomplish this with a timer. Could some one point me on the right track, I expect this would be an easy question for the people here. Thanks.

hi
i do not exactly understand what you want do. timers are not very accurate so you can not use them to create the frame rate. but you can use a timer to move the slide more or less synchronized. this can easy be done using the javax.swing.Timer
<snip>
Timer timer = new Timer(framerate, new ActionListener()
public void actionPerformed(ActionEvent ev)
// code to setup the slider
timer.setRepeats(true);
timer.setCoalesce (false);
timer.start();
</snip>
and to stop the timer use
<snip>
timer.stop();
</snip>
best regards
