void setup() {
  dispatch = new GripDispatcher(this);
  myGrip = new CircleGrip(50, 50, 40);
  myGrip.selectable = true;
}

void draw() {
  dispatch.update(); // Checks for hover
  dispatch.draw(); // Calls all the draw methods
}

class CircleGrip extends Grip {

  float x, y, diameter;

  CircleGrip(float x, float y, float diameter) {
    this.x = x;
    this.y = y;
    this.diameter = diameter;    
  }

  boolean isHovering() {
    return dist(mouseX, mouseY, x, y) < diameter/2;
  }

  void draw() {
    if (this.isTheActive()) {
      fill(0, 255, 0);
    } else {
      fill(255);
    }
    ellipse(x, y, diameter, diameter);
  }

}

Description

By default, Grip objects are not selectable. Meaning that when the mouseRelease() event fires, the Grip will no longer be active, and isTheActive() will return false. If selectable is true, this Grip will retain active status until the user clicks elsewhere.

myGrip.selectable = false;
