Ich just read the book OOP with Actionscript from Branden Hall and Samuel Wan. They explain OOP with AS in a simple and not to long way so that everyone can understand it. It also offers I summery of tricks from advanced flash developers. But that isn’t part of that thread. I came across the part about textfields and thought it would be handy if you could just use a textfield like a button e.g. myTextField_txt.onRelease = function … . So I extended the TextField class a little bit. It also returns a path to the recently created textfield.

MovieClip.prototype.createTextField2 = MovieClip.prototype.createTextField;
MovieClip.prototype.createTextField = function(name, depth, x, y, w, h){
        this.createTextField2(name, depth, x, y, w, h);
        return this[name];
}

TextField.prototype.$hitsMouse = function(){
        return this._x<=_root._xmouse
        && this._x+this._width>=_root._xmouse
        && this._y<=_root._ymouse
        && this._y+this._height>=_root._ymouse
}
TextField.prototype.$onMouseMove = function(){
        if(!this.$over && this.$hitsMouse()){
                if(this.$onRollOver_func != undefined)
                this.$onRollOver_func.apply(this, null);
                this.$over = true;
        } else if(this.$over && !this.$hitsMouse()){
                if(this.$onRollOut_func != undefined)
                this.$onRollOut_func.apply(this, null);
                this.$over = false;
        }
}
TextField.prototype.$onMouseUp = function(){
        if(this.$onRelease_func != undefined
        && this.$hitsMouse()){
                this.$onRelease_func.apply(this, null);
        } else if(this.$onReleaseOutside_func != undefined
        && this.$pressed
        && !this.$hitsMouse()){
                this.$onReleaseOutside_func.apply(this, null);
        }
        this.$pressed = false;
}
TextField.prototype.$onMouseDown = function(){
        if(this.$onPress_func != undefined
        && this.$hitsMouse())
        this.$onPress_func.apply(this, null);
        this.$pressed = true;
}
