Text issues
Jul 12th, 2007, 11:17pm  
Hey there,
So, I'm kind of a Java/Processing noob, so this is going to be a kind of basic issue.  But I have been playing with the Switchboard library, and want to display the results to an applet window, and have been having a hell of a time with that.  The problem seems to be with the text() function, the string and array.  

Specifically, the error I get is:

"No applicable overload for a method with signature "text(java.lang.String[], int, int, int, int)" was found in type "processing.core.PApplet". Perhaps you wanted the overloaded version "void text(java.lang.String $1, float $2, float $3, float $4, float $5);" instead?"

Anyone got any ideas?

Code:

import processing.opengl.*;
import org.switchboard.*;


Switchboard board;
ArrayList words = new ArrayList();

void setup() {
  size(300, 300, OPENGL);
  background(0);
  frameRate(10);

  board = new Switchboard(this);
  board.setYahooKey("xxxxxxx");

  board.yahooWeb("self");
}

void resultReceived() {

  words.add(board.yahooWeb.getSummary());
}



void draw() {
  String word[] = (String[]) words.toArray (new String [words.size ()]);
  println(word); //Check to make sure that the service is working
  PFont font = loadFont("HelveticaNeue-BoldItalic-48.vlw"); 
  textFont(font, 24); 
  fill(255);
  text(word, 10, 10, 300, 300); 
}

What you have is an array of words, what the function expects is a single string, you have 2 optioned, either write all the words individually, or join all the words together into a single string.
The single string is the easiest way I think:

Code:
 void draw() {
  String word[] = (String[]) words.toArray (new String [words.size ()]);
  println(word); //Check to make sure that the service is working
  PFont font = loadFont("HelveticaNeue-BoldItalic-48.vlw");  
  textFont(font, 24);  
  fill(255);
  String joinedwords=join(word," "); //converts an array of individual words
  //into a single string of them all
  text(joinedword, 10, 10, 300, 300);  
}

I can probbaly make things even better.. you're loading the font every frame.. it'd be better to load it in setup only.

Code:

PFont font;

void setup()
{
  .. other stuff...
  PFont font = loadFont("HelveticaNeue-BoldItalic-48.vlw");  
  textFont(font, 24);  
}

void draw()
{
  .. stuff .. no loadFont or textFont
  text(...);
}
