常數詳細資訊
ACTION_SCRIPT | 常數 |
public static const ACTION_SCRIPT:String = "actionscript"| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
The MetadataEvent.ACTION_SCRIPT constant defines the value of the
type property of the event object for a actionscript event.
These cue points are not embedded in the FLV file but defined
using ActionScript at run time.
The properties of the event object have the following values:
| Property | Value |
|---|---|
bubbles | false |
cancelable | false |
currentTarget | The Object that defines the
event listener that handles the event. For example, if you use
myButton.addEventListener() to register an event listener,
myButton is the value of the currentTarget. |
info | The index of the cue point in the VideoDisplay.cuePoint Array. |
target | The Object that dispatched the event;
it is not always the Object listening for the event.
Use the currentTarget property to always access the
Object listening for the event. |
CUE_POINT | 常數 |
public static const CUE_POINT:String = "cuePoint"| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
The MetadataEvent.CUE_POINT constant defines the value of the
type property of the event object for a cuePoint event.
The properties of the event object have the following values:
| Property | Value |
|---|---|
bubbles | false |
cancelable | false |
currentTarget | The Object that defines the
event listener that handles the event. For example, if you use
myButton.addEventListener() to register an event listener,
myButton is the value of the currentTarget. |
info | The index of the cue point in the VideoDisplay.cuePoint Array. |
target | The Object that dispatched the event;
it is not always the Object listening for the event.
Use the currentTarget property to always access the
Object listening for the event. |
METADATA_RECEIVED | 常數 |
public static const METADATA_RECEIVED:String = "metadataReceived"| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
The MetadataEvent.METADATA_RECEIVED constant defines the value of the
type property for a metadataReceived event.
This event has the following properties:
| Property | Value |
|---|---|
bubbles | false |
cancelable | false;
there is no default behavior to cancel. |
currentTarget | The Object that defines the
event listener that handles the event. For example, if you use
myButton.addEventListener() to register an event listener,
myButton is the value of the currentTarget. |
info | An object describing the FLV
file, including any cue points. This property contains the same information
as the VideoDisplay.metadata property.
See the VideoDisplay.metadata property for more information. |
target | The Object that dispatched the event;
it is not always the Object listening for the event.
Use the currentTarget property to always access the
Object listening for the event. |
vp | The index of the VideoPlayer object. |
