I'm using a Flash TextField control to display some HTML content inside a Flash presentation to be shown on a large touch-screen kiosk. Unfortunately, if any image tag in the displayed HTML content points to a non-existent image, a dialogue is shown with the error message
Error #2044: Unhandled IOErrorEvent:. text=Error #2035: URL Not Found.
I am trying to avoid having that dialogue pop up. The solution for loading content through a loader class is to catch IOErrorEvent.IO_ERROR, but I've tried listening for that on the TextField, on stage, Main and loaderInfo to no avail. I've tried wrapping the whole thing in a try-catch, and that also doesn't work.
Here's the simplified code I'm using to find solutions:
package {
import flash.display.Sprite;
import flash.errors.IOError;
import flash.events.Event;
import flash.events.IOErrorEvent;
import flash.text.TextField;
import flash.text.TextFieldType;
public class Main extends Sprite {
public function Main():void {
if (stage) init();
else addEventListener(Event.ADDED_TO_STAGE, init);
}
private function init(e:Event = null):void {
removeEventListener(Event.ADDED_TO_STAGE, init);
var html:TextField = new TextField();
html.type = TextFieldType.DYNAMIC;
html.multiline = true;
html.htmlText = "Bogus image: <img src=\"foo.jpg\" />";
addChild(html);
}
}
}
Edit: And here's the entire working code.
For dynamic content and so forth, of course, you would need a list of images and a function to generate handlers, etc.
package {
import flash.display.Loader;
import flash.display.Sprite;
import flash.errors.IOError;
import flash.events.Event;
import flash.events.IOErrorEvent;
import flash.text.TextField;
import flash.text.TextFieldType;
public class Main extends Sprite {
public function Main():void {
if (stage) init();
else addEventListener(Event.ADDED_TO_STAGE, init);
}
private function init(e:Event = null):void {
removeEventListener(Event.ADDED_TO_STAGE, init);
var html:TextField = new TextField();
html.type = TextFieldType.DYNAMIC;
html.multiline = true;
html.htmlText = "Bogus image: <img id=\"image\" src=\"foo.jpg\" />";
var loader:Loader = html.getImageReference("image") as Loader;
if(loader){
loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, function(e:Event):void {
trace("Error loading foo.jpg!");
});
}
addChild(html);
}
}
}
