This works for me:

boolean loseFocus;
void setup()
{
  size(300,300);
  background(0);
  loseFocus = false;
}  

void draw()
{
  if (focused && loseFocus) 
  {
    println ("get focus");
    loseFocus = false;
  } 
  else if (!focused)
  {
    loseFocus = true;
  }
}

@cameyo -- Interesting. That works for me as well on OS X 10.12.3 Processing 3.3.

I didn't know about focused -- where did you learn about it?

@jeremydouglass:
my editor highlights the word focused...
then I have found it within the file \processing-3\modes\java\keywords.txt :)
