Hello,

I would like to use the function full screen fullscreen();  
Using sliders, checkboxs, inputs and buttons that will disappear when we are in a full screen mode.

So basically I can work with sliders and then go full screen so only the canvas is visible

Any suggestions please

Thank you

you can make a variable

it is boolean named showSliders

initially it is true. Define it before setup().

Evaluate it in draw()

```auto
if(showSliders) {
    background(0);
    show sliders (screen A)
}else{
    background(0);
    show the other screen (screen B)
}

```

(in draw() nothing is allowed outside this if-clause, because either we are on one screen or the other)

**How to change the variable**

make a button on the slider screen “show” and when it’s clicked say `showSliders=false;`

in B for example when a key is pressed say `showSliders=true;`

I think that you can get sliders to function even if they are beneath the lower edge of the canvas. Saw this after I made a mistake one time. I don’t know how this lower than the canvas manipulation will react when you engage full screen, but it be a path for you.
