cleaning up

Is there a method that gets called when the applet's window closes? Something analagous to Lingo's
on stopMovie
I'm playing around with midi files and want to be able to stop the sequencer when the sketch is stopped rather than allow it to continue playing until the sequencer runs out of data.

There is public void stop() and public void dispose() from java.applet.Applet... You could overload those (might be wise to call the super.function in your overloaded version).

Thanks again Cello,
They both work:
public void stop(){
sequencer.stop();
}
public void dispose(){
sequencer.stop();
}
I'm afraid that some of your post went over my head - I don't know what super does yet or whether what I've done here is an example of overloading. Is it acceptable to do it this way? Also, which do you think would be better to use - stop or dispose? Is it unsafe to take the belt-and-braces approach?

the underlying BApplet class is doing its own cleanup stuff inside the stop() method, so this is why you have to "overide" it while using "super", e.g:
Code:public void stop() // your method
{
sequencer.stop();
super.stop(); // BApplet.stop()

I see. It's to make sure that the stop event moves up the chain.
