I have been able to use Swing components in a JFrame but not in the PApplet. Can I use Swing sliders, scollers, buttons etc ... in PApplet? If so how?

If not, can I write with processing and output to a JFrame?

Thanks,

Thanks Fry - I always search before I post, but I could not find a clean answer so I asked the question again. Next time I will post on the same thread.

I have had some succsess with a swing slider but its a bit buggy.

Code:

import javax.swing.JSlider;
import processing.core.PApplet;

public class test4 extends PApplet{
private static final long serialVersionUID = 1L;
public void setup() {
    size(400,300);
    JSlider slider = new JSlider();
    slider.setMinorTickSpacing(5);
    slider.setMajorTickSpacing(10);
    slider.setPaintTicks(true);
    slider.setToolTipText("The value is 50");
    add(slider);
    print(slider.getValue());
  }
} 

note*
You have to resize the window to bring the slider into view.
Running in opengl renders a black screen.

Has anyone ever made this work? I have been trying to no avail!

Here is what I have so far...

Code:

import java.awt.BorderLayout;
import java.awt.Container;

import javax.swing.JFrame;

public class test3 extends JFrame {
	pillar p1;
  public static void main(String[] args) {
    new test3();
  }
  public test3() { 
    super("Using JFrame");
    WindowUtilities.setNativeLookAndFeel();
    addWindowListener(new ExitListener());
    Container content = getContentPane();
    
    p1 = new pillar();
    content.add(p1, BorderLayout.SOUTH);
    pack();
    setVisible(true);
  }
} 

The pillar class that is called:

Code:

import processing.core.PApplet;

public class pillar extends PApplet{
public pillar(){
//size(1280, 900);
 }
} 

This will render without errors but as soon as I open up size (1280, 900) I get this error:

Exception in thread "main" java.lang.NullPointerException at processing.core.PApplet.updateSize(PApplet.java:912)

at processing.core.PApplet.size(PApplet.java:862)

at processing.core.PApplet.size(PApplet.java:792)

at processing.core.PApplet.size(PApplet.java:774)

at pillar.<init>(pillar.java:5)

at test3.<init>(test3.java:26)

at test3.main(test3.java:12)

I have tried as many variations of this code as I can think of and nothing works - can someone show me how this should be done?

Thanks,

Fantastic - thanks Fry!

Now can this also be done with OPENGL? When I run the code without OPENGL it works every time but when I add OPENGL in the setup() the code executes without errors but there is no visible jframe; there is however, a thread created in my task manager. To add more complexity, sometimes a jframe is produced and runs perfectly.

Here is what I have:

Code:

import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Container;

import javax.swing.BorderFactory;
import javax.swing.JFrame;
import javax.swing.JSlider;

public class Frame extends JFrame {
  pillar p1;
  public static void main(String[] args) {

  new Frame(); 
  }
  public Frame() { 
    super("Using JSlider");
    WindowUtilities.setNativeLookAndFeel();
    addWindowListener(new ExitListener());  
    Container content = getContentPane();
    content.setBackground(Color.white);
    
    p1 = new pillar();
    p1.init();
    content.add(p1, BorderLayout.SOUTH);
 
    JSlider slider1 = new JSlider();
    slider1.setBorder(BorderFactory.createTitledBorder("JSlider without Tick Marks"));
    content.add(slider1, BorderLayout.NORTH);
    
    pack();
    setVisible(true);
  }
} 

Code:

import processing.core.PApplet;
 
public class pillar extends PApplet{
	public void setup(){
		size(60,40, OPENGL);
	}
	public void draw() {
		//fill(120,1,120);
		//rect(20,20,20,20);
		  float x = mouseX - width/2;
		  background(255);
		  fill(0, 102, 153, 26);
		  for(int i=0; i<height; i+=10) {
		    for(int j=0; j<width; j+=10) {
			beginShape(QUADS);
			vertex(x+j,   i,    0);
			vertex(x+j, i+5,    0);
			vertex(j-x, i+5, -400);
			vertex(j-x,   i, -400);
			endShape();
		    }
	  }
	}
}

I have been working with this for a few days now and every once and awhile I get this error when I am trying to render the script with OPENGL:

Frame at localhost:2477 (may be out of synch) was unable to replace the running code with the code in the workspace.
Reason:
Hot code replaced failed – Scheme changed not implemented

Any thoughts on what this means? If there is a synch problem how do I go about fixing it? Could this be a machine specific problem?

Thanks,

thanks for posting the example.

however that's a gross mischaracterization of my position on this. i am not worried about "making this way of working more well known" and can't imagine i've ever said anything as such. this mode of operation is documented here:

http://dev.processing.org/reference/core/javadoc/processing/core/PApplet.html

and as i said above, i use this all the time for my own work, so it's not as though i somehow wish to hide it or prevent others from using it that way.

the only reason i don't spend more time talking about it, or contributing still more time to the "integration" board is because i'm already supporting a massive project, i don't need to complicate things further by supporting anyone who wants to program in java. i have limits, cut me some slack.
