Widget Visibility - Cp4 and 5

Question

How do you detect when the widget is no longer visible or has left the stage?  Widget visibility is affected by the user scrubbing the playbar, user hitting the playbar "next" button, or if the user has hidden it via Advanced Actions.  I'm seeing some inconsistencies with the widget visible = true and isWidgetVisible().  It would be nice to have an event dispatched when the widget leaves the building.
I've overridden the visibility property of the widget, but that isn't enough since using Advanced Actions doesn't modify the widget.visible property.
For Cp 5, the only way I can imagine doing this is to listen for the SlideEnter event, then execute the following logic if the slide number is the same slide the widget is on:
add an event listener for the enterFrame event
inside of the onEnterFrame handler, execute the isWidgetVisible() function to know if the widget has left the stage.
For Cp4, there is no SlideEnter event.  What would be the best method?
Thanks for any insight,

Jim,
I built a custom playbar not widget, but same might work for you.
I had an animation play on the next/forward button when the slide ended. I set a variable  = to current slide and then had the animation clip listen to the new values of current slide and compare it to the variable, and if different, stop playing the animation.
////////////////////////NEXT ANIMATION FUNCTIONALITY///////////////////////////////////////
//addEventListener(Event.ENTER_FRAME, nextAnimationStarted);
function nextAnimationStarted() {
     var startAnim = _parent._parent._parent._parent.startNextAnimation; //This is a User var I built that on on slide animation sets to 1 when it needs to begin
     var currentSlideNumber = _parent._parent._parent._parent.movie.cpInfoCurrentSlide;
     var totalSlideNumber = _parent._parent._parent._parent.rdinfoSlideCount;
     var thisIsDisabled = _parent._parent._parent._parent.disableForward;    
     if (getSet == null){
               var getSet = 1;
     if (startAnim == 1 && thisIsDisabled == 0) {
          if (currentSlideNumber != totalSlideNumber) {
               if (getSet == 1 && _parent._parent._parent._parent.setCurrentSlide == 0){
                    _parent._parent._parent._parent.setCurrentSlide = currentSlideNumber;
                    this.textTrial.text = "Set to 1";
                    this.gotoAndPlay("startFrame");
               } else if (getSet == 1 && _parent._parent._parent._parent.setCurrentSlide == currentSlideNumber){
                    this.gotoAndPlay("startFrame");
               } else if (getSet == 1 && _parent._parent._parent._parent.setCurrentSlide != currentSlideNumber){
                    _parent._parent._parent._parent.startNextAnimation = 0;
                    _parent._parent._parent._parent.setCurrentSlide = 0;
                    getSet = null;
          } else {
               //Do Nothing();
nextAnimationStarted();
play();
This is AS2 Cap4 but something similar can be done in AS 3. Sidenote I have also used setInterval to pass variables/check variables for changes as well, and that has worked...just ok.
That might lead you in the right direction..maybe not. Hope it helps.
