controlp5 ControlWindowCanvas: adding methods
Nov 9th, 2008, 3:49pm  
im am having issues adding a method addText(String) to the class StoryCanvas which extends ControlWindowCanvas. When addText("test")  is called the compiler says "The function addText(String) does not exist". Is it not possible to add methods to classes which inherit ControlWindowCanvas?

Code:

import controlP5.*;

ControlP5 controlP5;

ControlWindow controlWindow;
ControlWindowCanvas storyCanvas;

void setup() {
  controlP5 = new ControlP5(this);

  controlWindow = controlP5.addControlWindow("controlP5window", 100, 100, 400, 400);
  controlWindow.setBackground(color(0));

  storyCanvas = new StoryCanvas();
  storyCanvas.addText("addText");

  controlWindow.addCanvas(storyCanvas);
}

class StoryCanvas extends ControlWindowCanvas {
  String text =  "";

  StoryCanvas() {

  }

  public void addText(String itext) {
    text = itext;
  }

  public void draw(PApplet p) {

  }
}

you have to define your variable to be of type "StoryCanvas", otherwise Processing will not see the functions you've added:

StoryCanvas storyCanvas;
