I have a program with 3 buttons, namely start/stop/step. I have a loop which moves a circle around on a JPanel. I want the loop to be started when the user presses "start" and the loop to "stop" when the user presses stop (the program has to remember the current state of the loop). When the users presses start again the loop has to start where it left of. When the user presses "step" the loop has to make one step in the loop (step will only be possible when the loop is stopped). What is the easiest way to do this? Do I need to threat my program to listen to the buttons while my loop is running?
Yes, you basically would have a thread running that animates the circle. (You might want to use a Timer or something.)
The Buttons would change the state of a model, which the timer uses to determine what exactly it should do.
