Constructor.

參數

	`type:String` — The event type; indicates the action that caused the event.

常數詳細資訊

THUMB_DRAG

常數

public static const THUMB_DRAG:String = "thumbDrag"

語言版本:

ActionScript 3.0

產品版本:

Flex 4

執行階段版本:

Flash Player 10, AIR 1.5

The TrackBaseEvent.THUMB_DRAG constant defines the value of the type property of the event object for a thumbDrag 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`.
`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.

THUMB_PRESS

常數

public static const THUMB_PRESS:String = "thumbPress"

語言版本:

ActionScript 3.0

產品版本:

Flex 4

執行階段版本:

Flash Player 10, AIR 1.5

The TrackBaseEvent.THUMB_PRESS constant defines the value of the type property of the event object for a thumbPress 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`.
`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.

語言版本:

ActionScript 3.0

產品版本:

Flex 4

執行階段版本:

Flash Player 10, AIR 1.5

The TrackBaseEvent.THUMB_RELEASE constant defines the value of the type property of the event object for a thumbRelease 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`.
