Use multiple Sketch/Application windows
May 19th, 2008, 8:03pm  
Hello,

I was wondering if its possible to use more than one window for one sketch. For example if you want to run one window fullscreen and a small one with some control/handler things. For example if you'd want to build a small VJ tool and want to run the animation in a seperate window(on another screen) than the controls. I find it pretty hard to put all controls on the keyboard.

greetings!

Hm, something like that?

PFrame f;
secondApplet s;

void setup() {
 size(320, 240);
 PFrame f = new PFrame();
}

void draw() {
  background(255,0,0);
   fill(255);
   rect(10,10,frameCount%100,10);
   s.background(0, 0, 255);
   s.fill(100);
   s.rect(10,20,frameCount%120,10);
   s.redraw();
}

public class PFrame extends Frame {
    public PFrame() {
        setBounds(100,100,400,300);
        s = new secondApplet();
        add(s);
        s.init();
        show();
    }
}

public class secondApplet extends PApplet {
    public void setup() {
        size(400, 300);
        noLoop();
    }

    public void draw() {
    }
}

this one opens a second OpenGL frame

Quote:

import javax.media.opengl.*;
import com.sun.opengl.util.FPSAnimator;

void setup() {
 size(400, 300);
 
 Frame f = new Frame("OPENGL frame");
 GLCanvas canvas = new GLCanvas();
 canvas.addGLEventListener(new GLRenderer());
 f.add(canvas);
 f.setSize(300, 300);
 f.setLocation(0,0);
 f.setUndecorated(true);
 f.show();
 FPSAnimator animator = new FPSAnimator(canvas, 60);
 animator.start();
}

void draw() {
 background(0);
 fill(255);
 rect(10,10,frameCount%100,10);
}

class GLRenderer implements GLEventListener {
 GL gl;

 public void init(GLAutoDrawable drawable) {
   this.gl = drawable.getGL();
   gl.glClearColor(0, 0, 0, 0);
 }

 public void display(GLAutoDrawable drawable) {
   gl.glClear(GL.GL_COLOR_BUFFER_BIT | GL.GL_DEPTH_BUFFER_BIT );
   gl.glColor3f(1, 1, 1);
   gl.glRectf(-0.8, 0.8, frameCount%100/100f -0.8, 0.7);
 }
 
 public void reshape(GLAutoDrawable drawable, int x, int y, int width, int height) {
 }

 public void displayChanged(GLAutoDrawable drawable, boolean modeChanged, boolean deviceChanged) {
 }
}

maybe thats a dumb question but can I run one fullscreen(presentation mode) at a second Monitor while I have the small one on my main Monitor?

I can't test it right now. thanks in advance!

I think 'presentation mode' doesnt work with two monitors. The second will always be black. Try something with  frame.setUndecorated(true) and frame.setLocation(screen.width,0); If you want to hide Apples menu bar see here -> http://processing.org/discourse/yabb_beta/YaBB.cgi?board=Syntax;action=display;num=1135921427

yes thank you, I allready found thos threads. I will see where I can go with this when I have a second monitor!

EDIT:

so even if I use frame.setUndecorated(true); I still have the mac bar of the processing applet on top. But its a good start i guess!

EDIT2:

Okay this code in the setup does it for me:
Quote:

frame.dispose();
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice displayDevice=ge.getDefaultScreenDevice();
frame.setUndecorated(true);
displayDevice.setFullScreenWindow(frame);
Dimension fullscreen = frame.getSize();
this.setBounds((fullscreen.width - this.width) / 2,
(fullscreen.height - this.height) / 2,
this.width, this.height);

I just realised that Sojamos Controlp5 lib has a nice feature for more windows. So everybody who wants to use a second window to control the main window should take a look at this:

http://www.sojamo.de/libraries/controlP5/

and especially this:

http://www.sojamo.de/libraries/controlP5/examples/ControlP5window/ControlP5window.pde

Thanks for that really great lib!

Hi All,

I just started using Processing, so I apologize if this is already clear to others.  I am trying to get two separate opengl windows going and they seem to be conflicting with each other (obviously shared memory buffers, lots of exceptions regarding destroying contexts, etc.)  When I use on with opengl and another with P3D, it works just fine.

Any thoughts?

thanks!
