Hi there,
I'm building a sketch with various subclasses, all based on pulling in various data streams. All work fine except this part that calls yahoo weather data. As I'm still a learner-driver and after a lot of puzzling I still can't figure out what the problem is.- It keeps tellng me "The constructor XMLRequest (weatherclass.WeatherClass( int, int) is undefined".

To try to solve it, I've simplefied the code just calling the weather data and visualising it as a dot. It works fine as a "classless" sketche. But if I try using a "class" I get the same remark. What am I doing wrong?

Is it the parameters in the constructor, it does not make a difference if I put none or 1 in there?

Here are both codes:
'classless':

------------------------------------------------------------------------------------------------------------------------------------
import simpleML.*;

int temperature;
int weather;

//-----------------------
void setup() {
  size(200, 200);
  smooth();

  XMLRequest xreq = new XMLRequest(this, "http://weather.yahooapis.com/forecastrss?w=26360988&u=c");
  xreq.makeRequest();
}
//-----------------------

void draw() {
  background(255);
  dotObject();
}
//--------------------

void getWeather() {
  String url = "http://weather.yahooapis.com/forecastrss?w=26360988&u=c";
  XMLRequest req = new XMLRequest(this, url);
  req.makeRequest();
  println ("loaded from xml.weather.yahoo.com");
}

void netEvent(XMLRequest ml) { // Get the specific XML content we want
  temperature = int(ml.getElementAttributeText("yweather:condition", "temp"));
  weather = int (ml.getElementAttributeText("yweather:condition", "code"));
}
//------------------------
void dotObject() {

  fill (100);
  ellipse (weather*2, temperature*2, weather, weather);
}

------------------------------------------------------------------------------------------------------------------------------------
with class:

------------------------------------------------------------------------------------------------------------------------------------
import simpleML.*;

WeatherClass dotObject;
//-------------------------------------
void setup() {
  size(200, 200);
  smooth();

  dotObject = new WeatherClass (0,0);
 
}
//-----------------------------------

void draw() {
  background(255);
  dotObject.display();
}
//////////////////////////

class WeatherClass {
  int x, y;
  int temperature;
  int weather;

  //-----------------------------------
  WeatherClass () {
 
    XMLRequest xreq = new XMLRequest(this, "http://weather.yahooapis.com/forecastrss?w=26360988&u=c");
    xreq.makeRequest();
  }

  void display() {
    dot();
  }
  //-----------------------------------
  void getWeather() {
    String url = "http://weather.yahooapis.com/forecastrss?w=26360988&u=c";
    XMLRequest req = new XMLRequest(this, url);
    req.makeRequest();
    println ("loaded from xml.weather.yahoo.com");
  }
  //-----------------------------------
  void netEvent(XMLRequest ml) { // Get the specific XML content we want
    temperature = int(ml.getElementAttributeText("yweather:condition", "temp"));
    weather = int (ml.getElementAttributeText("yweather:condition", "code"));
  }
  //----------------------------------- 
  void dot () {

    fill (255,0,0);
    ellipse (weather*3, temperature*3, weather, weather);
  }
}

------------------------------------------------------------------------------------------------------------------------------------

Thanks for your time, help and suggestions!

Hi
I'm trying to make a clock that shows real time, so it can work as a timer as well as trigger events. ( i want it for sunrise and sunset. I found some code here in the forum that helps as far as it creates  the clock, but it doesn't refresh.
What am I doing wrong?
ps is the if statement right as a trigger (it's not accurate, but will be linked up to yahoo xml)?
thanks
nanette
here is the code:

import java.util.*;

 Calendar calendar = new GregorianCalendar();
  String am_pm;
  int hour = calendar.get(Calendar.HOUR);
  int minute = calendar.get(Calendar.MINUTE);
  int second = calendar.get(Calendar.SECOND);
// int  framerate (60);
 
void setup() {
  size (200, 200);
  smooth();
  background (255);
  if (calendar.get(Calendar.AM_PM) == 0) {
    am_pm = "AM";
  }
  else {
    am_pm = "PM";
  }
  println("Current Time : " + hour + ":" + minute + ":" + second + " " + am_pm);
}


void draw () {
   background (255);
  fill (0);
  textAlign (CENTER);
  textSize (20);
 text ("Current Time : \n "+ hour + ":" + minute + ":" + second + " " + am_pm,  width/2, height/2);
 
  if (hour>6 && minute>= 53 && am_pm== "AM") {
    fill (0,255,255);
    rect (width/2, 10, 40, 40);
  }
  if (hour>6 && minute>= 13 && am_pm== "PM") {
    fill(255,255,255);
    rect (width/2, 10, 40, 40);

  }
 
}
