Ok, if you're getting this from an rss feed then you're not going to like
this. Also this solution uses mx_internal. If you don't know what that is,
it's a set of methods/properties, that adobe says may change so they should
be used with extreme care because your code might break on updates.
However, in this case we're using it once to avoid creating a subclass so I
think it's a fair trade.
import mx.core.mx_internal;
use namespace mx_internal; // this line should be right after the import
statements.
...
textArea.htmlText = rssText;
textArea.validateProperties(); // initializes image loaders
var textField:UITextField = textArea.getTextField(); // mx_internal line to
get textField of TextArea
for (each imageID in rssText) { // how you actually implement this psuedo
code line depends on the rssText you already have
var loader:Loader = textField.getImageReference(imageID) as Loader;
var loaderInfo:LoaderInfo = loader.contentLoaderInfo;
if (loaderInfo.bytesLoaded != loaderInfo.bytesTotal) { // it would be
pointless to add listeners to loaders that have completed
loaderInfo.addEventListener(IOErrorEvent.IO_ERROR,
imageLoaderErrorListener); // you might want to use weakReference here for
memory management if it works.
}
}
public function imageLoaderErrorListener(event:IOErrorEvent):void {
// inform user if you want.
}
