slideDuration | 類型: Number 格式: Time CSS 繼承: 否 語言版本: ActionScript 3.0 產品版本: Flex 4 執行階段版本: 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. 預設值為 300。 | TrackBase | ||

建構函式詳細資料
TrackBase | () | 建構函式 |
public function TrackBase()| 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 |
Constructor.
方法詳細資訊
pointToValue | () | 方法 |
protected function pointToValue(x:Number, y:Number):Number| 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 |
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.
參數
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 | () | 方法 |
protected function updateSkinDisplayList():void| 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 |
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.
