求助：processing中ControlP5库如何添加按钮属性

yklzz

下面是改了例程中的代码，运行没有问题，现在想添加隐藏属性如何实现：
import controlP5.*;
ControlP5 cp5;
void setup() {
  size(400,600);
  noStroke();
  cp5 = new ControlP5(this);  
  // create a new button with name 'buttonA'
  cp5.addButton("colorA")
     .setValue(0)
     .setPosition(100,100)
     .setSize(200,19)
     ;
}
void draw() {
  
}
public void colorA(int theValue) {
  println("a button event from colorA: "+theValue);

//  在这里加上隐藏按钮的语句（说明文档中这句代码如何实现隐藏  controlP5.Controller : Button hide() ）
  
}

  



/*
下面是说明文档
a list of all methods available for the Button Controller
use ControlP5.printPublicMethodsFor(Button.class);
to print the following list into the console.

You can find further details about class Button in the javadoc.

Format:
ClassName : returnType methodName(parameter type)
*
*
*
controlP5.Controller : Button hide()
*
*
