IOErrorEvent | () | Constructor |
public function IOErrorEvent(type:String, bubbles:Boolean = false, cancelable:Boolean = false, text:String = "", id:int = 0)
Language Version: | ActionScript 3.0 |
Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
Creates an Event object that contains specific information about ioError
events.
Event objects are passed as parameters to Event listeners.
type:String — The type of the event. Event listeners can access this information through the inherited type property. There is only one type of input/output error event: IOErrorEvent.IO_ERROR .
| |
bubbles:Boolean (default = false ) — Determines whether the Event object participates in the bubbling stage of the event flow. Event listeners can access this information through the inherited bubbles property.
| |
cancelable:Boolean (default = false ) — Determines whether the Event object can be canceled. Event listeners can access this information through the inherited cancelable property.
| |
text:String (default = " ") — Text to be displayed as an error message. Event listeners can access this information through the text property.
| |
id:int (default = 0 ) — A reference number to associate with the specific error (supported in Adobe AIR only).

IOErrorEventExample
class to show how an error
event object is dispatched when an attempt is made to load a nonexistent file. The example carries out the following tasks:
- The class constructor creates a new instance of a URLLoader object and assigns it to the variable
loader
. - The URLLoader instance instantiates an event listener of type
ioError
, which has an associated subscriber methodioErrorHandler()
, which simply prints information about the event usingtrace()
. - Next, the constructor creates a new instance of a URLRequest object,
request
, passingMissingFile.xml
so that the name and location of the missing file are known. - The
request
variable is then passed toloader.load()
, which attempts to load the missing file. Since the file is missing, the event handler dispatches anioError
event.
Notes:
- You need to compile the SWF file with "Local Playback Security" set to "Access Local Files Only".
- Make sure that you do not have a file named "MissingFile.xml" at the same level as your SWF file.
