using .setSize() with controlP5 imageButtons

edited August 2016 in Library Questions

Hi there guys, here is the default example for imageButton with ControlP5. (one can find it under Examples)

I was wondering if there was a way to scale up/down say the rolloverImage by a few pixels. So that when you rollover with your mouse the button appears to pop in place.

I tried .setSize(int,int) before .updateSize(); but it does nothing. If you remove the line .updateSize() it freezes.

Any ideas? Tried the java docs but unsure of the syntax/method here.

import controlP5.*;

ControlP5 cp5;

int myColor = color(0);

void setup() {
  size(400, 600);
  cp5 = new ControlP5(this);

  // replace the default controlP5 button with an image.
  // button.setImages(defaultImage, rolloverImage, pressedImage);
  // use button.updateSize() to adjust the size of the button and 
  // resize to the dimensions of the defaultImage

    .setPosition(175, 275)
      .setImages(loadImage("Arrow-Left.png"), loadImage("Arrow-Right.png"), loadImage("Refresh.png"))

void draw() {

public void controlEvent(ControlEvent theEvent) {

// function buttonA will receive changes from 
// controller with name buttonA
public void buttonA(int theValue) {
  println("a button event from buttonA: "+theValue);
  myColor = color(128);
