Processing, keep window on top/ overlay

I have been looking at this and could not find anything to really help.

I want to make my canvas in Processing to stay over the top of other windows, I have worked out how to do this but when you load up a game the game hides the canvas behind it.

I have found that the following has to be used but I do not know or in what context compared to processing:

DirectDraw or inject a dll and hook directx

If you're using Processing 3 (and you should be), then you should no longer use the frame variable- the other answer doesn't seem to do anything in Processing 3.

Instead, use the surface variable:

void setup(){
  size(200, 200);
  surface.setAlwaysOnTop(true);
}

void draw(){
  background(0);
  ellipse(mouseX, mouseY, 10, 10);
}

More info on the changes made in Processing 3 can be found here and here.

No need to hook DirectX yourself, just insert this line in your setup function:

frame.setAlwaysOnTop(true);

(As an aside, this thread on the Processing forum was the first result when googling "processing window stay on top").
