slideDuration | Type: Number Format: Time CSS Inheritance: No Language Version: ActionScript 3.0 Product Version: Flex 4 Runtime Versions: Flash10, AIR 1.5 Duration in milliseconds for a sliding animation when you click on the track to move a thumb. This style is used for both Sliders and Scrollbars. For Sliders, any click on the track will cause an animation using this style, as the thumb will move to the clicked position. For ScrollBars, this style is used only when shift-clicking on the track, which causes the thumb to move to the clicked position. Clicking on a ScrollBar track when the shift key is not pressed will result in paging behavior instead. The smoothScrolling style must also be set on the
ScrollBar to get animated behavior when shift-clicking.
This duration is for an animation that covers the entire distance of the track; smaller distances will use a proportionally smaller duration. The default value is 300 . | TrackBase | ||

This component uses skins made up of skin parts. Do not set the skin parts directly. The component's skin sets the skin parts.
Skin Part | Description | Defined By | ||
---|---|---|---|---|
thumb:Button | Required: false Part Type: Static Language Version: ActionScript 3.0 Product Version: Flex 4 Runtime Versions: Flash10, AIR 1.5 A skin part that defines a button that can be dragged along the track to increase or decrease the value property. Updates to the value property automatically update the position of the thumb button with respect to the track. | TrackBase | ||
track:Button | Required: false Part Type: Static Language Version: ActionScript 3.0 Product Version: Flex 4 Runtime Versions: Flash10, AIR 1.5 A skin part that defines a button that, when pressed, sets the value property to the value corresponding with the current button position on the track. | TrackBase |
To skin the component, implement a skin that defines the following states. Although you must implement all skin states, a skin state can be empty. An empty skin state specifies no changes to the default skin state.
TrackBase | () | Constructor |
public function TrackBase()
Language Version: | ActionScript 3.0 |
Product Version: | Flex 4 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Constructor.
pointToValue | () | method |
protected function pointToValue(x:Number, y:Number):Number
Language Version: | ActionScript 3.0 |
Product Version: | Flex 4 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Converts a track-relative x,y pixel location into a value between the minimum and maximum, inclusive.
TrackBase subclasses must override this method and perform conversions that take their own geometry into account. For example, a vertical slider might compute a value like this:
return (y / track.height) (maximum - minimum);
By default, this method returns minimum
.
Parameters
x:Number — The x coordinate of the location relative to the track's origin.
| |
y:Number — The y coordinate of the location relative to the track's origin.
|
Number — A value between the minimum and maximum, inclusive.
|
updateSkinDisplayList | () | method |
protected function updateSkinDisplayList():void
Language Version: | ActionScript 3.0 |
Product Version: | Flex 4 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Sets the bounds of skin parts, typically the thumb, whose geometry isn't fully specified by the skin's layout.
Most subclasses override this method to update the thumb's size, position, and
visibility, based on the minimum
, maximum
, and value
properties.
By default, this method does nothing.
change | Event |

currentTarget | The object that is actively processing the Event object with an event listener. |
target | The object that has had its value modified.
The target is not always the object in the display list
that registered the event listener. Use the currentTarget
property to access the object in the display list that is currently processing the event. |
