// Color
color BG = color(32);
color Red = color(255,13,13);
color Blue = color(24,22,240);
color Green = color(51,229,52);
color Purple = color(116,41,240);

color Orange = color(255,157,52);
color White = color(255);
color Grey = color(175);
color Black = color(0);

color pickedColor;

//Switching between modes
 static final int NONE = 0;
 static final int RECTANGLE = 1;
 static final int CIRCLE = 2;
 static final int TRIANGLE = 3;

//Store current mode
 int myDrawMode = NONE;

//Palette Dimension
int paletteWidth = 125;
int paletteHeight = 150;

import controlP5.*;

ControlP5 controlP5;

ListBox l;
int cnt = 0;

void setup(){
  size(500,500);
  background(BG); // suppose to put in void draw but that screws up my paint app.....
  smooth();
  frameRate(30);
  controlP5 = new ControlP5(this);
  l = controlP5.addListBox("myList",130,20, 260,120);
  l.setItemHeight(15);
  l.setBarHeight(15);
 
  l.captionLabel().toUpperCase(true);
  l.captionLabel().set("Instructions");
  l.captionLabel().style().marginTop = 3;
  l.valueLabel().style().marginTop = 3; // the +/- sign

  for(int i=0;i<1;i++) {
    l.addItem("Press 1,2,3 to change draw modes and 4 to restart "+i,i);
  }
  l.setColorActive(color(0,10,255,128));
  l.setColorActive(color(0,0,255,128));

}
