How can make my sketch know when the mouse is moved OUTSIDE of the sketch window?

The question says it all. If I'm not mistaken, I need to use something that consists of a Robot, or something like that?

@TechWiz777, please choose "Ask a Question" rather than "New Discussion" for questions! :>

Indeed w/ class Robot we can check mouse coordinates for the whole desktop:

However we still need to find out which of those belong to the actual sketch's area! >-)
Nonetheless I did a focused + thread("") sample. Check it out: B-)

static final int POOLING_DELAY = 100;

void setup() {
  size(400, 300, JAVA2D);
  noLoop();
  thread("focusThread");
}

void draw() {
  println(frameCount, focused);
}

void focusThread() {
  boolean previous = focused;

  for (;; delay(POOLING_DELAY))  if (previous != focused) {
    redraw = true;
    previous = focused;
  }
}
