macromedia style- change/click handler

[heyder]

How can I set-up an event handler like on some of the macromedia components.

ie.. a user defined function recieves a callback from the component when clicked.

I found the code below but I not sure how to get it working with a new component (I have listed what I have tried to this point)

//put this inside the component 

ComponentClass.prototype.setClickHandler = function(chng,obj) {
        this.handlerObj = (arguments.length<2) ? this._parent : obj;
        this.clickHandler = chng;
};

ComponentClass.prototype.executeCallBack = function() {
        this.handlerObj[this.clickHandler](this);
};

//added this code to main timeline
componentInstanceName.setClickHandler("myClick", _root);


function myClick(component) {
        trace (component);
}

I know I missing some stuff but not sure what...

Looks good to me. And you have set up an onPress or onRelease somewhere that will call the executeCallBack?

How does that part work?

componentname.onPress=function(){
myClick();
}

Well, it depends on how you've set it up. Normally, you might do it in the component's init method (or whatever initialization script you have for the Class):

ComponentClass.prototype.init = function() {
        // other code
        this.onPress = this.executeCallback;
};

Great, thanks. Makes sense now.
