Text input into code
Nov 7th, 2006, 2:06pm  
Hi,  

I am starting out in processing, but have a few weeks experience behind me now. I am planning to create a series of programs that will help teach simple architecture in processing. I need however to find a way to input text into the applet, and then use that input text to change parameters such as:

User enters x and y co-ords, width and height
Processing outputs square with co-ords x and y and width and height specified.

I have played around with the 'interfascia' library and I'm sure this could be useful but any pointers would be much appreciated.

For simple input, you could use class JOptionPane of the Java library, http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/JOptionPane.html

Code:

import javax.swing.JOptionPane;

float x;
float y;
float w;
float h;

void setup() {
  String input = JOptionPane.showInputDialog("Enter x, y, width and height, separated by spaces");
  String[] args = split(input);
  x = float(args[0]);
  y = float(args[1]);
  w = float(args[2]);
  h = float(args[3]);
  size(200,200);
}
void draw() {
  background(0);
  rect(x, y, w, h);
}

/Rick

Many thanks Rick, exactly the piece of code i needed and so simple! Already playing around with many possibilities.

Again many thanks
