Hi everyone!

I am currently creating an online portfolio using Slideshowpro ([www.slideshowpro.net](http://www.slideshowpro.net)).

For some of my pictures I am using (external) captions from a XML file, inserted into a dynamic textfield. As some of the captions contain a lot of text I decided to add a UIScrollBar. However, when there is no text (no caption) available, I want the scrollbar to be hidden. Also if there is not enough text to warrant a scrollbar it would be great if it could be hidden!

Please if you feel you can help, take a look at my current code below. If you have any pointers as to how I can accomplish this then please let me know! All help is much appreciated 🙂

Code below, note that “t\_txt” is the instance name of my dynamic textfield:

import flash.text.TextField;  
import net.slideshowpro.slideshowpro.\*;  
import fl.controls.UIScrollBar;

XML.ignoreWhitespace = true;  
//remove scrollbar from stage, scrollbar component must be in library  
var sbContent:UIScrollBar = new UIScrollBar();  
sbContent.move(t\_txt.x+t\_txt.width,t\_txt.y);  
sbContent.setSize(t\_txt.width, t\_txt.height);  
sbContent.scrollTarget = t\_txt;  
addChild(sbContent);

function onImageData(event:SSPDataEvent) {  
if (event.type==“imageData”) {  
t\_txt.htmlText=event.data.caption;  
sbContent.update();  
}  
}

slide.addEventListener(SSPDataEvent.IMAGE\_DATA, onImageData);
