Where did you see a 0198 revision? It isn't listed in the download page. Is that an Android only release?

its on google code. ;D

Ah, there is even a 0199 version! We are close of the 2.0...

It works, but how to stop it from outside?

In general, you don't stop a thread from outside, you send a signal (or just set a variable) notifying the thread to stop itself (it just returns).

Has anyone successfully made the thread sleep? I don't seem to be able to get it to work?

What have you tried? What do you want to do?

Inside the thread itself? How do you check that? Can you show a simple code demonstrating it?

Your program is OK.

The delay is in fact working in that it changes the colour every second for the first 10 seconds. The sleep command will not affect the main loop with the draw command.

The thread will execute for the number of iterations (10) x sleep interval (1000 ms) i.e. 10 seconds after that time the colour does not change.

You can see this if you modify the program slightly to this the time is printed out every 1000 milli seconds.

14.   println(time);
