Want scrollable log trace or text edit? here's how:

HTML:

JS:

this.modesModel = {scrollbars: true, mode: "vertical"},
    this.controller.setupWidget('scrollID', {}, this.modesModel);
    this.scroller = this.controller.get('scrollID');
    this.scrollStarting = this.scrollStarting.bind(this);
    this.controller.listen(this.scroller, Mojo.Event.scrollStarting, this.scrollStarting);

MyAssistant.prototype.scrollStarting = function(event) {
        event.scroller.addListener(this);
        Mojo.Log.info(new Date(), "scroll starting");           
    }

MyAssistant.prototype.AddLog= function(str,bClear)
{
   
   if(bClear==undefined){
        if(this.controller.get('scrolling_contents').innerHTML.length>0)
            this.controller.get('scrolling_contents').innerHTML+="<br />";
        this.controller.get('scrolling_contents').innerHTML+=str;       
    }
    else if(bClear==true)
    {
        this.controller.get('scrolling_contents').innerHTML=str;
    }

}
