Prevent closing all frames

clankill3r

I want to make a sketch that can open other sketches. So far it goes good but I can't change the behaviour of the sketches that are opened on runtime.

Why has the setDefaultCloseOperation no effect?

(Also, it should be DISPOSE_ON_CLOSE but I'm using DO_NOTHING_ON_CLOSE for testing).

public class AllSketches extends PApplet {

    public static void main(String[] args) {
        PApplet.main("forMyself.AllSketches", args);
    }

    P5_BackFaceCulling backFaceCulling;

    public void setup() {


        // works
        ((JFrame)getFrame()).setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);

    }

    public void draw() {

    }

    public void keyPressed() {
        if (key == '1') {
            println("test");

            Frame f = backFaceCulling.getFrame();

            if (f instanceof JFrame) {
                // why has this no effect?
                ((JFrame)f).setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
                println("changed setDefaultCloseOperation");
            }

        }
    }

}

I got it. The sketch I loaded was using a 3d renderer. Whatever getFrame() was returning was not an JFrame.
