Hello, i couldn’t find anything useful on the topic about toggling fullscreen (like F11 in browsers for example). Also how do i run a windowed sketch at the size of the screen? Because if I try this:

```auto
void setup(){
  size(displayWidth,displayHeight);
}

```

im getting an error.

Thanks in advance!

Guess you are searching for that …

Would something like this work? It uses _windowResize()_. Hit space bar to get full screen; hit some other key to reset.

```auto
final int _wndW = 400;
final int _wndH = 400;

void setup() {
  size(_wndW, _wndH);
  surface.setResizable(true);
  background(209);
}

void draw() {
}

void keyPressed() {
  if (key == 32) { // space bar
    windowResize(displayWidth, displayHeight);
  } else {
    windowResize(_wndW, _wndH);
  }
}

```

I tried replacing this with `fullScreen()` which doesn’t work.

`fullScreen()` does MORE than `windowResize(displayWidth, displayHeight);` since the position gets also changed.

Can we change the position to 0,0 ?

You might try the [windowMove](https://processing.org/reference/windowMove_.html) method.

`Can we change the position to 0,0 ?`  
_setLocation()_ might work:[https://processing.org/reference/setLocation\_.html](https://processing.org/reference/setLocation_.html)

Here is the code to be able to resize the sketch and switch it to and from fullscreen while it is running: void setup(){ fullScreen(); surface.setResizable(false); surface.setAlwaysOnTop(true); } // Sets the x and y position of the screen aswell as the width and height void screen(int x, int y, int w, int h){ surface.setLocation(x, y); surface.setSize(w, h); } /…

I’ve experimented with surface.setSize(), surface.setResizable(true) etc, but after a ton of googling I still can’t find a way to switch between windowed and fullscreen during the sketch. Is this a limitation of Processing or am I just missing something here? Any help is greatly appreciated
