question about widgets

[Karl Tiedt]

I'm actually diving into "creating" a widget... I havent been able to
find what I needed, so I'm taking the SlideShow widget and using it as
a reference in creating a new widget.... Quick description...

I'm calling it HtmlImageBanner as its purpose is to take a background
image, and to fade in "x" random images... so an banner 800 pixels
wide could have 5 different 160 pixel "banners" rotating in over it...
my question is since I want to try and keep this as "expandable" as
possible, I've let a spot where you can define the # of banners to
create over the background..
this of course means I now have an "unknown" number of img items to
create... if I use eval inside of a loop, will that work? (I remember
there being some weird issues with eval... thats why I'm asking) and
in conjunction with that...if I do an eval like "var tempObj =
eval("this.tile"+i); and then set properties on tempObj will that work
for setting properties of the newly created this.tileX objects?

Thats all I can think of for now... :)
Thanks!!

Hi Karl,

I'm not sure why you are talking about eval.  Does "img items" mean
image domnodes? You can just do:

for(var i=0;i<10;i++){
        var img document.createElement("img");
        this.domNode.appendChild(img);
}

(or something like that)
Probably I didn't understand what you were saying.
