Hi all,

I'm sure this is a simple Java question, but it's eluding me so I thought I'd post here:

I'm trying to add a Text Area to a 2nd "console" window for a current Processing app. I have it working fine when it's added to the main display window (simple example below):

Code:

// add text area to display window

Panel inputPanel;
TextArea textarea;

void setup(){
  size(320, 110);
  background(50);

  inputPanel = new Panel();  
  inputPanel.setLayout(new BorderLayout());
  add(inputPanel);
  inputPanel.setBounds(5, 5, 310, 100); // left x, top y, width, height
  
  textarea = new TextArea("");  
  // A border layout lays out a container, arranging and resizing its components to fit in five regions: 
  // Each region is identified by a corresponding constant: NORTH, SOUTH, EAST, WEST, and CENTER. 
  inputPanel.add(textarea, BorderLayout.CENTER);
  setLayout(new BorderLayout());
} 

void draw() {
}
 

But I can't get it to work in the 2nd window. See below:
Code:

// attempting to draw text area in 2nd window

UIWindow uiWindow; 
PFont font; // must load a font for TextButton class

void setup() {
  uiWindow = new UIWindow(320, 110, 15,"Console"); // width, height, framerate, font name, window name
  background(0);
  size(320, 240);
  frameRate(60); // framerate for main window
}

void draw() { // add stuff here to draw to main window
  background(0);
}


public class UIWindow extends PApplet { // class for 2nd window
  Frame frame;
  int width;
  int height;
  int fps;
  String windowName;
  
  Panel inputPanel;
  TextArea textarea;  

  UIWindow (int w, int h, int framerate, String name) {
    width = w;
    height = h;
    fps = framerate;
    windowName = name;
    frame = new Frame();
    frame.setBounds(0, 0, width, height);
    frame.setLocation(0, 0);
    frame.setResizable(false); // set to true to change window size
    frame.add(this);
    this.init();
    frame.show();
  }

  void setup() {
    size(width, height, P2D);
    frameRate(fps); // framerate for 2nd window
    frame.setTitle(windowName);
    //noLoop();
    
    inputPanel = new Panel();  
    inputPanel.setLayout(new BorderLayout());
    add(inputPanel);
    inputPanel.setBounds(5, 5, 310, 100); // left x, top y, width, height
    
    textarea = new TextArea("");  
    // A border layout lays out a container, arranging and resizing its components to fit in five regions: 
    // Each region is identified by a corresponding constant: NORTH, SOUTH, EAST, WEST, and CENTER. 
    inputPanel.add(textarea, BorderLayout.CENTER);
    setLayout(new BorderLayout());    
  }

  void draw() { // add stuff here to draw to 2nd window
    // draw stuff in console window
  }
}
 

Can anyone help. I'm not interested in using the controlP5 library for this - would rather figure this out. Thanks for the help!

best,
Zachary

Hi NoahBuddy,

Compare the first code snippet with the second and you'll see what I'm talking about. You can't type into the second text area, or at least I can't. Can you?

frame.pack(), that's it! Thanks for the help.

Zachary
