Is there a button event versus a mouse event in html5 canvas

The moving clock is the only available object. Within Flash it made sense. Click to stop and start the motion. Only now in HTML the object doesn't behave as a button. (Misbehaves.)

Actually, the clock is a collection of movie clips. Clock hands, clock face, etc. The "thisring" object serves to make the clock clickable. I'm not sure how you'd turn it into a button. To all intents it is a button, a moving one.

The actual code has this:

     lib.ring = function(mode,startPosition,loop) {
      this.initialize(mode,startPosition,loop,{});

     // Layer 1
      this.shape = new cjs.Shape();
     this.shape.graphics.f("rgba(252,255,214,1)").s().p("AnGQ2QjShZiiiiQiiiihZjSQhbjZAAjuQAAjtBbjZQBZjSCiiiQCiiiDShZQDZhbDtAAQDuAADZBbQDSBZCiCiQCiCiBZDSQBbDZAADtQAADuhbDZQhZDSiiCiQiiCijSBZQjZBbjuAAQjtAAjZhbg");

     this.timeline.addTween(cjs.Tween.get(this.shape).wait(1));

}).prototype = getMCSymbolPrototype(lib.ring, new cjs.Rectangle(-116.9,-116.9,233.9,233.9), null);

     // ring

     this.ring = new lib.ring();

     this.ring.name = "ring";

     this.ring.parent = this;

     this.ring.alpha = 0; // invisible instance

     var thisring = this.ring;

     // timeline functions:

     function initfunction() {

     if (count == stopit) {

     new cjs.ButtonHelper(thisring, 0, 1, 1);

     thisring.addEventListener("mouseout", handleOut);

     thisring.addEventListener("mouseover", handleOver);

     thisring.addEventListener("click", handleClick);

     thisring.addEventListener("mouseup", handleRelease);

     clearInterval(initI); }

      }

     var initI = setInterval(initfunction, 33);

I certainly would appreciate code to fix the mouse pointer.

It moves in small steps. A set of random x y coordinates are calculated and the object drifts there at .1 pixels per move, so if the pointer happens to be in its path, it slides under the pointer. To stop and start the motion you can click on thisring. thisring is a circle that has an alpha transparency of 0.01. (Invisible objects are unclickable.) The thisring object is in front of a round clock that is visible and moves in sync.

Mouse pointer appearance in Flash also responds to "this.buttonMode = true". An equivalent variable for Canvas would be nice.
