Hello. I want to finish my processing paint program but I ran into some complications. My goal is to take out the grey rectangle and move the squares on the right hand side of the GUI Screen on the Y axis in a single vertical column. Once thats done I want to include the circles and finaly the Eraser.

 

Please don't go totally overboard on this I am a newbie so when you want to make a suggestion show your code but explain it so that I can comprehend this tnx.

 

Here is what I have so far...

 

class Button {
  color c;
  boolean isRect;
  float h;
  float w;
  float x;
  float y;
 
  Button() {
    h = 20;
    w = 20;
  }
 
  Button(color cVal, boolean isRectVal, float xVal, float yVal) {
    this(); // call base constructor
    c = cVal;
    isRect = isRectVal;
    x = xVal;
    y = yVal;
  }
 
  boolean within(float xVal, float yVal) {
    if (isRect) {
      return(xVal > x - w/2 && xVal < x + w/2 && yVal > y - h/2 && yVal < y + h/2);
    } else {
      // assume a circle
      return(dist(xVal, yVal, x, y) < h/2);
    }
  }
 
  void display() {
    stroke(0);
    strokeWeight(1);
    fill(c);
    if (isRect) {
      rectMode(CENTER);
      rect(x,y,w,h);
    } else {
      ellipseMode(CENTER);
      ellipse(x,y,w,h);
    }
  }
}

I need help to finish my paint program. I want to relocate the rectangles and circles on the right side of the GUI screen on the Y axis in two rows one for rectangles and one for circles. The only problem is is that when I did just that the paint program could not  paint the colours of the shapes it could only paint black.

 

This is what I have so far.

int Red;

  Green = color(0,255,0);
  Blue = color(0,0,255);
  black = color(0);
  LightGrey = color(200);
  currentColor = color(102);
  typeIsRect = true;
  PFont font;
  textAlign(CENTER);
  fill(95, 245, 183);
