| doMeasure | () | method |
override protected function doMeasure(availableWidth:Number, availableHeight:Number):LayoutMeasurementMeasures the size of the component so that it can be reported to the layout framework for laying the component out properly.
Parameters
availableWidth:Number — The avaliable size in the x dimension dictated by the measurements of the parent. Controls should not exceed this size.
| |
availableHeight:Number — The avaliable size in the y dimension dictated by the measurements of the parent. Controls should not exceed this size.

| drawFill | () | method |
protected function drawFill():voidDraws the fill of the slider. The default implentation sets the width of the fill based on a percenatge of the track width.
| setFillSkin | () | method |
public function setFillSkin(skin:Object):voidSets the fill skin for the slider. The fill skin is the area of the track to the left of the slider thumb button (in a horizontal slider) that represents the current value of the slider.
You can pass in a qualified class name String, or the actual class.
In either instance the class that is used must implement the ISkin interface.
Note: Do not pass in an instance of a skin class. This may cause unexpected behavior.
Parameters
skin:Object — The fill skin to set.
|
| setThumbSkin | () | method |
public function setThumbSkin(skin:Object):voidSets the skin for the slider thumb button. The thumb is the button that the user moves along the track to change the value of the slider.
You can pass in a qualified class name String, or the actual class.
In either instance the class that is used must implement the ISkin interface.
Note: Do not pass in an instance of a skin class. This may cause unexpected behavior.
Parameters
skin:Object — The button skin to set.
|
| setTrackSkin | () | method |
public function setTrackSkin(skin:Object):voidSets the skin for the track of the slider. The track is the vertical or horizontal line that the thumb button moves along.
You can pass in a qualified class name String, or the actual class.
In either instance the class that is used must implement the ISkin interface.
Note: Do not pass in an instance of a skin class. This may cause unexpected behavior.
Parameters
skin:Object — The track skin to set.

| thumbPositionChanged | () | method |
protected function thumbPositionChanged():voidCalled when the position of the thumb on the x axis has changed. Occurs when the user drags the thumb or has clicked on the track. You can override this method if you wish to have elements update themselves based on the value property.
| thumbPressed | () | method |
protected function thumbPressed():voidCalled when the thumb has been pressed by the user.
You can override this method to perform custom actions when the user presses the thumb.
| thumbReleased | () | method |
protected function thumbReleased():voidCalled when the thumb has been released by the user.
You can override this method to perform custom actions when the user has released the thumb.
| trackPressed | () | method |
protected function trackPressed():voidCalled when the thumb has been pressed by the user.
You can override this method to perform custom actions when the user presses the thumb. The default implementation of this method moves the thumb to where the user has pressed and initiates a drag operation.
