Say I'm in a while loop doing something. I want processing to update it's keyboard and mouse status, and possibly update the drawing too while I'm in the loop. Is there any method that processing uses to update itself? I want to be able to call that method from within a loop. The reason I want to do this, is so that I can have something looping until a key is pressed, using something like while(key != 'A'); But the keyboard won't update on its own accord. I want it to look more like this:

1. while(key != 'A')
2. {
3.       updateKeyboard();
   
4. }

But what is the name of this updateKeyboard() method? How will I implement it if it isn't already there?
