Question

这是我的图像生成器，可以切换。我想在新窗口中显示切换按钮。我尝试使用PApplet，但它似乎没有任何显示。如何为切换添加额外的窗口？

import controlP5.*; 

PFont myFont;

boolean showBackground = false;
boolean showObjects = false;
boolean showGrids = false;
boolean showType = false;

ControlP5 cp5;

PImage[] objects = new PImage[30];
PImage[] grids = new PImage[29];
PImage[] backgrounds = new PImage[30];
PImage[] type = new PImage[30];

int currentBackgrounds;
int currentGrids;
int currentObjects;
int currentType;


void setup() {
  size(1436, 847);

  //load objects
  for (int i=0; i<objects.length; i++) {
    objects[i] = loadImage  ( "o" + i + ".png");
  }
  //load grids
  for (int i = 0; i < grids.length; i++) {
    grids[i] = loadImage  ( "g" + i + ".png");
  }
  //load backgrounds
  for (int i = 0; i < backgrounds.length; i++) {
    backgrounds[i] = loadImage( "b" + i + ".jpg");
  }
  //load type
  for (int i = 0; i < type.length; i++) {
    type[i] = loadImage  ("t" + i + ".png");
  }
  //setup UI
String[] args = {"TwoFrameTest"};
SecondApplet sa = new SecondApplet();
PApplet.runSketch(args, sa);

}
public class SecondApplet extends PApplet {

public void settings() {
    size(200, 100);
  }
  // create a toggle and change the default look to a switch look
  public void draw() {
  cp5 = new ControlP5(this);

  PFont font = createFont("EurostileLTStd-BoldEx2.otf", 10);


  cp5.addToggle("showBackground")
    .setColorForeground(color(255, 255, 255)) 
    .setColorBackground(color(255, 255, 255))
    .setColorActive(color(255, 0, 0))
    .setPosition(40, 250)
    .setFont(font)
    .setSize(20, 20)
    .setValue(false)
    .setMode(ControlP5.SWITCH);

  cp5.addToggle("showObjects")
    .setPosition(40, 400)
    .setFont(font)
    .setSize(50, 20)
    .setValue(false)
    .setMode(ControlP5.SWITCH);

  cp5.addToggle("showGrids")
    .setPosition(40, 600)
    .setFont(font)
    .setSize(50, 20)
    .setValue(false)
    .setMode(ControlP5.SWITCH);

  cp5.addToggle("showType")
    .setPosition(40, 800)
    .setFont(font)
    .setSize(50, 20)
    .setValue(false)
    .setMode(ControlP5.SWITCH);
  }
}

void mousePressed() {
  //next img 
  currentObjects = currentObjects + int(random(10));
  currentGrids = currentGrids + int(random(10));
  currentType = currentType + int(random(10));
  currentBackgrounds = currentBackgrounds + int(random(10));

  if (currentObjects >= objects.length) {
    currentObjects = 0;
  }
  if (currentGrids >= grids.length) {
    currentGrids = 0;
  }
  if (currentType >= type.length) {
    currentType = 0;
  }
  if (currentBackgrounds >= backgrounds.length) {
    currentBackgrounds = 0;

  }
}

void draw() {
  //clear frame
  background(211);//

  if (showBackground==true) {
    image(backgrounds[currentBackgrounds], 0, 0, 1436, 847); // b
  } 
  if (showGrids==true) {
    image(grids[currentGrids], 0, 0, 1436, 847); // g
  } 
  if (showObjects==true) {
    image(objects[currentObjects], 0, 0, 1436, 847); // o
  }
  if (showType==true) {
    image(type[currentType], 0, 0, 1436, 847); // o
  }
}

您必须为第二个窗口调用runSketch()函数才能弹出并成为自己的Processing sketch。像这样：

void setup() {
  String[] args = {"TwoFrameTest"};
  SecondApplet sa = new SecondApplet();
  PApplet.runSketch(args, sa);
}

void settings() {  
  size(300, 100);
}

void draw() {
  background(0);
  fill(255);
  text("Hello world!", 50, 40);
}   


public class SecondApplet extends PApplet {

  public void settings() {
    size(200, 200);
  }

  public void draw() {
    background(255);
    fill(0);  
    text("Hello world!", 50, 40);
  }
}
