i can't figure out how to disable the button input, i use

background(255);

it gets rid of all the text on the screen other than whats on the buttons, but the buttons remain in place and won't

go away

i am using the button grouping thing (I edited the example for Buttons on the processing website!), i thought i could just type

circle1.noDisplay();

but apparently that does not work, PLEASE HELP ME!

The Buttons as implemented in that example don't support being disabled. You have to add that, but it's not hard.

Add a variable to the button class:

class Button

{

int x, y;

int size;

color basecolor, highlightcolor;

color currentcolor;

boolean over = false;

boolean pressed = false;

boolean disabled = false; // <-- add this

Change the display code on the CircleButton class as follows:

void display()

{

if (!disabled) { // <-- add this line

stroke(255);

fill(currentcolor);

ellipse(x, y, size, size);

} // <-- add this brace

}

Change the display code on the RectButton class in the same way

Then, to disable a button do

circle1.disabled = true;
