ControlP5 button event

Processing Libraries
1

Dear all,
I wrote the following code:

// --8<-------8<-------8<-------8<-------8<-------8<-------8<-------8<-------8<-----

// ```
ControlP5 cp5;


final static String BUTTON_START="buttonStart";




 void initForm()
  {
    cp5 = new ControlP5(this);
    // cp5.setVisible(true);
   
    PImage[] imgs = {loadImage(PATH+PATH_BUTTON+BUTTON_START+RELEASED+".png"), loadImage(PATH+PATH_BUTTON+BUTTON_START+OVER+".png"), loadImage(PATH+PATH_BUTTON+BUTTON_START+PRESSED+".png")};
    cp5.addButton("start")
      .setValue(128)
      .setPosition(140, 300)
      .setImages(imgs)
      .updateSize()
      ;
      

  }


 public void start(int theValue) {
    println("a button event from buttonB: "+theValue);
    // exit();
    
  }

// --8<-------8<-------8<-------8<-------8<-------8<-------8<-------8<-------8<-----

// the draw() routine is empty

void draw()
{
}

It works but the function public void start(int theValue) is called even if the mouse is not clicked over the relative button.
Do you have any similar problem ? How do you fix it ?
Thank you very much for cooperation
regards

Please format the code by highlighting it and pressing the </> button in the text editor.

Thank you for suggestion

Is this all you code? I can’t see that you are checking for er the mouse to be pressed anywhere.
Which library are you using?

ok, what i see with this:

import controlP5.*;

ControlP5 cp5;

void setup()
{
  cp5 = new ControlP5(this);

  //    PImage[] imgs = {loadImage(PATH+PATH_BUTTON+BUTTON_START+RELEASED+".png"), loadImage(PATH+PATH_BUTTON+BUTTON_START+OVER+".png"), loadImage(PATH+PATH_BUTTON+BUTTON_START+PRESSED+".png")};
  cp5.addButton("start")
    .setValue(128)
    .setPosition(10, 10)
    //      .setImages(imgs)
    .updateSize()
    .setLabel("START");
  ;
}

void draw() {
}

public void start(int theValue) {
  println("a button event from button START: "+theValue);
}

you are right, yes, at start i see already a “event line”

ControlP5 2.2.6 infos, comments, questions at processing GUI, controlP5
a button event from button START: 128

and add at every mouse click

if you want to use a other LIB?

import g4p_controls.*;

GButton button1;
import java.awt.Font;

void setup() {
  size(100, 100);
  button1 = new GButton(this, 10, 10, 80, 30);
  button1.setText("START");
  button1.setFont(new Font("Arial", Font.BOLD, 18));
  button1.setLocalColorScheme(0);
  
}

void draw() {
}

void handleButtonEvents(GButton button, GEvent event) {
  if (button == button1) { 
    println(" button1 clicked ");
  }
}
