| ProgressEvent | () | constructor |
public function ProgressEvent(type:String, bubbles:Boolean = false, cancelable:Boolean = false, bytesLoaded:uint = 0, bytesTotal:uint = 0)Creates an Event object that contains information about progress events. Event objects are passed as parameters to event listeners.
Parameterstype:String — The type of the event. Possible values are:ProgressEvent.PROGRESS
and ProgressEvent.SOCKET_DATA.
|
|
bubbles:Boolean (default = false) — Determines whether the Event object participates in the bubbling stage of the event flow.
|
|
cancelable:Boolean (default = false) — Determines whether the Event object can be canceled.
|
|
bytesLoaded:uint (default = 0) — The number of items or bytes loaded at the time the listener processes the event.
|
|
bytesTotal:uint (default = 0) — The total number of items or bytes that will be loaded if the loading process succeeds.
|
| clone | () | method |
public override function clone():EventCreates a copy of the ProgressEvent object and sets each property's value to match that of the original.
ReturnsEvent —
A new ProgressEvent object with property values that match those of the original.
|
| toString | () | method |
public override function toString():String
Returns a string that contains all the properties of the ProgressEvent object. The string is in the following format:
[ProgressEvent type=value bubbles=value cancelable=value bytesLoaded=value bytesTotal=value]
ReturnsString —
A string that contains all the properties of the ProgressEvent object.

| PROGRESS | constant |
public static const PROGRESS:String = "progress"
Defines the value of the type property of a progress event object.
This event has the following properties:
| Property | Value |
|---|---|
bubbles | false |
bytesLoaded | The number of items or bytes loaded at the time the listener processes the event. |
bytesTotal | The total number of items or bytes that ultimately will be loaded if the loading process succeeds. |
cancelable | false; there is no default behavior to cancel. |
currentTarget | The object that is actively processing the Event object with an event listener. |
target | The network object reporting progress. |

ProgressEventExample class to illustrate how various
event listeners are used when a file is being downloaded. The example carries out the following tasks:
downloadURL and fileName are created, which indicate the location
and name of the download file.ProgressEventExample constructor, a new FileReference object named file is
created and then passed to the configureListeners() method.downloadURL and fileName properties are then passed to file.download(),
which prompts for the location to download the file.configureListeners() method adds seven event listeners and their associated subscriber
methods:cancel/cancelHandler() is dispatched if the file download is canceled.complete/complereHandler() is dispatched when the file download process is
finished.ioError/ioErrorHandler() is dispatched if the download file is unavailable or
inaccessible.open/openHandler() is dispatched when the download operation has started.progress/progressHandler() is dispatched when the download process begins and again
when it ends.securityError/securityErrorHandler is dispatched if the local playback
security setting does not match the type of data access for the download file (local versus network);
see the notes below.select/selectHandler() is dispatched when the download object is selected.Notes:
