I am using G4P GUI Designer creating a PID Controller Screen to interface serially with a custom designed Arduino PID Controller. I created many Custom Sliders using the GUI Designer, but I do not get Mouse Wheel events through the G4P Slider Control Event Method. I want to use mouseWheel Events since it provides greater control of value settings than with mouseDragged Events, when considering my old shaky hands. I DO GET the G4P Control mouseWheel Events in my "Main Window", but how do I translate the mouseWheel(Event) to spSliderChange(Object, Event)? Or better yet, how do I get the mouseWheel Events to occur in the GUI slider event handlers?

Example Slider generated by GUI Designer (I have 10 of them total in GUI) which do not get mouseWheel Events, however the G4P controls do get mouse drag and steady events:

public void spSliderChange(GCustomSlider source, GEvent event) { //_CODE_:spSlider:950263:
  println("custom_slider1 - GCustomSlider >> GEvent." + event + " @ " + millis());
} //_CODE_:spSlider:950263:

public void createGUI() {
    G4P.messagesEnabled(false);
    G4P.setGlobalColorScheme(GCScheme.BLUE_SCHEME);
    G4P.setCursor(ARROW);
    surface.setTitle("Sketch Window");
    spSlider = new GCustomSlider(this, 120, 410, 300, 80, "blue18px");
    spSlider.setShowValue(true);
    spSlider.setShowLimits(true);
    spSlider.setRotation(PI/2, GControlMode.CORNER);
    spSlider.setLimits(0.5, 1.0, -1.0);
    spSlider.setShowTicks(true);
    spSlider.setNumberFormat(G4P.DECIMAL, 2);
    spSlider.setOpaque(false);
    spSlider.addEventHandler(this, "spSliderChange");
}

GCustomSlider spSlider;

And this in my "Main Window" which does get mouseWheel Events on slider:

void mouseWheel(MouseEvent event) {
    println(" - mouseWheel >> GEvent." + event + " @ " + millis());
}

I appreciate your input, who ever responds. I am not a GUI designer, but rather a low level 'C' and 'C++' coder. Your help is appreciated!

Thank you!

Hi guys, I'm a newbie in processing I am working on a game that requires text field, but unfortunately it is not editable, and I do not know why,

Hi all, new to Processing and would appreciate some help!

I'm trying to make a class where each instance of it has a sinOsc playing at a different frequency, with a slowly decreasing (and then increasing) volume for each. I can't find much in the way of in-depth tutorials on this object, and am stuck! here's the code:

PImage img;
import processing.sound.*;
SinOsc sine;


Sphere s1;
Sphere s2;

void setup() {
  size(665, 800);
  img = loadImage("MK.png");
  s1 = new Sphere(random(0, (img.height/2)), random(0, (img.width/2)), 255, 10);
  s2 = new Sphere(random(0, (img.height/2)), random(0, (img.width/2)), 255, 17);
  sine = new SinOsc(this);
  image (img, 0, 0, img.width/2, img.height/2);

  s1.bells();
  s2.bells();
}

//variables
int time = millis();


void draw() {
  s1.run();
  s2.run();


}

`

and for the class (Sphere) itself:

class Sphere {

  //GLOBAL
  float xpos = 0;//set variables for the class, default for all of this type
  float ypos = 0;
  int col1 = 255;
  int decay = 8;
  int timer;
  Float amp = 0.5;
  Float freq = (random(80, 400));
  int trans = 255;



//CONSTRUCTOR
    Sphere(float _xpos, float _ypos, int _col1, int _decay){
      xpos = _xpos;//args for each instantiation can then alter the global vars
      ypos = _ypos;
      col1 = _col1;
      decay = _decay;
    }


void run(){
  display();

}

void display(){
fill(col1, 0, 0, trans);
  ellipse(xpos, ypos, 10, 10);//global vars now altered to reflect creation args

  if (millis() - timer >= (decay * 10)){
     trans = trans - 10;
     amp = amp - 0.1;
     timer = millis();
   }

  if (trans <= 0){
     trans = 255;
   }
}

void bells(){

  sine.play();
  sine.freq(freq);
  sine.amp(amp);

}
}

Any help would be appreciated!

Hello,

I'm trying to improve the performance of a program using threads for the development of the heaviest tasks.

However, I have problems with this code, and I can´t find a solution.

What I can do?

public class ClientThread extends Thread {


    public ClientThread(String str) {
        super(str);
    }
    public void run() {

      Client myClientC = new Client(this, "192.168.1.88" , 6025);
      }catch(Error e){}
    }
}
void setup(){
        ClientThread AAA = new ClientThread("ClientThread 1");
        AAA.start();
     }

hello!

im have almost no programming experience and would be greatful for help :-) i wrote a small program toggling a slideshow & sounds (mp3) with arduino buttons, but it doesn't run stable.

when i press the buttons on arduino quickly, processing crashes with an error window. i wouldn't mind, but others are going to use it in a situation where chances are high they will hit the buttons quickly! it crashes, saying:

Java(TM) SE Platform binary doesn't work any more

i figued, if i cut out the part of code dealing with sound, i can hit the arduino buttons in a frenzy without problems.

a second matter is, if i try to export the sketch and run it as an *.exe (i close processing entirely to free the serial port) it just loads some blank screen, nothing happens. i have no i idea what to look for in this second matte. i am still guessing it doesn't start because there's a communication issue between arduino and the program once it's an *.exe?

Hey all,

I'm working on a spatial sound installation project and have hit a wall when it comes to sending specific audio to specific speakers.

My setup:

• Processing with Minim (playback and effects) and Javasound (targeting the different sound cards)

• 3 stereo USB mini sound cards connected to a USB hub

• 5.1 surround speakers with 3 stereo output jacks, 1 for front left/right, 1 for rear left/right, and 1 for center/subwoofer

The idea is that unique mp3s are played through each speaker, but I can't seem to get deeper than the stereo device level when assigning outputs in Minim, so I can only assign audio on a per-soundcard basis rather than a per left/right channel basis. After I've found the correct output mixer with the Mixer.Info class and set it with .setOutputMixer() to the AudioOutput, I'm at a loss for how to find each left/right channel within the Mixer object.

Printing the output from mixer.getTargetLineInfo() on one of the soundcard mixers I create just gives me a single result:

interface TargetDataLine supporting 8 audio formats, and buffers of at least 32 bytes

when I would expect to see something like

• Output right channel
• Output left channel

Has anyone figured out how to target on a per channel basis? This is way harder than I was imagining it would be.

Hello!

I am using a new library (github.com/dimr/mapzen-processing) developed by Dimitris Rongotis in order to generate a 3D map with open data. I'd like to generate a camera path through that map. Basically so that people can "site see" along the map. I'll be embedding poems inside the map, and zooming up to look at them. Also thinking about scraping tweets, embedding them into the map in real time, and setting the camera to look at new ones that show up on the map (they're geo-located). Thing is, for some reason, pro-scene is cutting off sections of the map and I can't figure out why? Does anybody have any idea why this is happening?

I am looking to send an Email from Processing. I am gathering data, and would like an easy way to send alerts when certain events happen.

It looks like this has been covered in the past but most of the resources have been deprecated. Shiffman had a pretty good one but that is not listed anymore: http://www.shiffman.net/2007/11/13/e-mail-processing/

Is this an easy thing to do? I figured it might be fairly useful and widespread.

Thank you for any tips or advice.

Hi guys, I have a basic set up of an animation storyline in which when the user clicks the mouse or does certain interactions, it then runs the next 'screen' or next animation. The issue I'm having is that on screen 5 a click of the mouse plays a video I made in after effects. However, this video then stops on the last frame and stays. I cannot work out how to 'screen++' after the video stops. I have tried duration, millis, etc. and nothing seems to be working. Could somebody please shed some light on what might be going on, or how I could achieve this?

Hello, I'm new on processing. I'm trying to put my sketch in a class, so I can later on build more stuff on top. But a the very beginning of that I get an error on : cam = new Capture(this, 320, 240, 30); "the constructor doesn't exist". But it does, it's in the library. Any idea how to solve that ? Thanks

Hi all,

I have got stuck by this trouble. I am now using Eclipse to write the programs of Processing, and I kept having troubles. The latest one I am facing is regarding the Sound library. I created a SinOsc object and use

sine = new SinOsc(this);

to initialise a new object. It works fine in Processing, but when I run it in Eclipse, the error messages pop out:

Exception in thread "Animation Thread" java.lang.UnsatisfiedLinkError: no MethClaInterface in java.library.path

    SinOsc sine;

    public void settings(){
        size(600,600);

    }
}

Thank you!!

I was just wondering if it is possible to use blob detection to trigger a key board press. so if my hand went over to a certain part of the screen where i want it to correlate to the letter "w" for example it signals that "w" was pressed on the keyboard?

i have downloaded the blob detection library but im not to sure how to use it what i want to do is have 4 different buttons so when blob detection picks up the blob it that specific area it would either play a video or signal a keyboard press to play a video in resolume?

when many no. clients are connected with the server and for any reason when clients disconnected or closed socket with server , how to identify which of the clients disconnected from server at server side application program.

Hi there,

I was wondering if anyone could help me detect whether or not there is movement in just a specific area of a camera capture?

The idea is if a hand is moving in one area, an object starts to move one way, if movement is detected in the a different area the object moves the other way.

I've looked at the motion sensor example (http://learningprocessing.com/examples/chp16/example-16-14-MotionSensor) but I'm not sure how to just limit the 'sensor' to certain regions on the screen!

Would really appreciate any help!!

Thanks.

I wrote my sketch in processing 2.2.1 at windows 7 64 bit. To avoid CPU Consuming, I decided to build a script which is executable in Linux utilizing export feature of processing. Although both of original sketch in Windows 7 and its standalone file run perfectly in windows 7, but the linux script (standalone file for linux namely linux.application64) does not run in Ubunto 12. Noting I use last version of Simpleopenni library in my code and i get the following error: "cant load Simpleopenni library (libsimple openni64.so):java.lang.unsatisfied link error: cant load the library"

Would you please help me to solve this problem?

Hi Folks,

I've created a drum sequencer using the controlP5 matrix and I'm looking to use pushbuttons on an Arduino to turn on and off the buttons. Firstly, is this possible? and if so, how do I tell the matrix to take input from the pushbutton instead of the mouse click?

Any help would be much appreciated.

Cheers,

Hi, I'm having no success trying to import the tactu5 library version 1.0.2 under processing 3.1.1 (I'm running on a Mac with Yosemite 10.10.5). I get an error saying that there was an "Error during download and install of tactu5." It created a temporary folder in the libraries folder but the example program SimpleExample.pde can't find any of the library files. Does anyone know of a work around?
