Hide MXML SyntaxThe Slider class cannot be used as an MXML tag. Use the <mx:HSlider>
and <mx:VSlider> tags instead. However, the Slider class does define tag
attributes used by the <mx:HSlider> and <mx:VSlider> tags.
The Slider class inherits all of the tag attributes of its superclass, and adds the following tag attributes:

Positions the elements of the control.
The track, thumbs, labels, and tick marks are all positioned
and sized by this method.
The track is sized based on the length of the labels and on the track margin.
If you specify a trackMargin, then the size of the track
is equal to the available width minus the trackMargin times 2.
Tick marks are spaced at even intervals along the track starting from the beginning of the track. An additional tick mark is placed
at the end of the track if one doesn't already exist (if the tick interval isn't a factor of the maximum value). The tick mark
y-position is based on the tickOffset. An offset of 0 places the bottom of the tick at the top of the track. Negative offsets
move the ticks upwards while positive offsets move them downward through the track.
Labels are positioned at even intervals along the track. The labels are always horizontally centered above their
interval position unless the trackMargin setting is too small. If you specify a trackMargin, then the first and last labels will
position themselves at the left and right borders of the control. Labels will not crop or resize themselves if they overlap,
so be sure to allow enough space for them to fit on the track. The y-position is based on the labelOffset property. An offset of 0
places the bottom of the label at the top of the track. Unlike tick marks, the labels can not be positioned to overlap the track.
If the offset is a positive number, then the top of the label will be positioned below the bottom of the track.
The thumbs are positioned to overlap the track. Their x-position is determined by their value. The y-position is
controlled by the thumbOffset property. An offset of 0 places the center of the thumb at the center of the track. A negative
offset moves the thumbs upwards while a positive offset moves the thumbs downwards.
The placement of the tick marks, labels and thumbs are all independent from each other. They will not attempt to reposition themselves if they overlap.
For a vertical slider control, the same rules apply. In the above description, substitute width for height, height for width, left for up or top, right for down or bottom, x-position for y-position, and y-position for x-position.
Parameters
unscaledWidth:Number — Specifies the width of the component, in pixels,
in the component's coordinates, regardless of the value of the
scaleX property of the component.

| change | Event |
mx.events.SliderEventmx.events.SliderEvent.CHANGE| Language Version : | ActionScript 3.0 |
| Product Version : | Flex 3 |
| Runtime Versions : | Flash Player 9, AIR 1.1 |
Dispatched when the slider changes value due to mouse or keyboard interaction.
If the liveDragging property is true,
the event is dispatched continuously as the user moves the thumb.
If liveDragging is false,
the event is dispatched when the user releases the slider thumb.
SliderEvent.CHANGE constant defines the value of the
type property of the event object for a change event.
The properties of the event object have the following values:
| Property | Value |
|---|---|
bubbles | false |
cancelable | false |
clickTarget | Specifies whether the slider track or a slider thumb was pressed. |
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. |
keyCode | If the event was triggered by a key press, the keycode for the key. |
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. |
thumbIndex | The zero-based index of the thumb whose position has changed. |
triggerEvent | Contains a value indicating the type of input action. The value is an event object of type flash.events.MouseEvent or flash.events.KeyboardEvent. |
value | The new value of the slider. |
| thumbDrag | Event |
mx.events.SliderEventmx.events.SliderEvent.THUMB_DRAG| Language Version : | ActionScript 3.0 |
| Product Version : | Flex 3 |
| Runtime Versions : | Flash Player 9, AIR 1.1 |
Dispatched when the slider's thumb is pressed and then moved by the mouse.
This event is always preceded by a thumbPress event.
SliderEvent.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 |
clickTarget | Specifies whether the slider track or a slider thumb was pressed. |
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. |
keyCode | If the event was triggered by a key press, the keycode for the key. |
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. |
thumbIndex | The zero-based index of the thumb whose position has changed. |
triggerEvent | Contains a value indicating the type of input action. The value is an event object of type flash.events.MouseEvent or flash.events.KeyboardEvent. |
value | The new value of the slider. |
| thumbPress | Event |
mx.events.SliderEventmx.events.SliderEvent.THUMB_PRESS| Language Version : | ActionScript 3.0 |
| Product Version : | Flex 3 |
| Runtime Versions : | Flash Player 9, AIR 1.1 |
Dispatched when the slider's thumb is pressed, meaning the user presses the mouse button over the thumb.
TheSliderEvent.THUMB_PRESS constant defines the value of the

The properties of the event object have the following values:
| Property | Value |
|---|---|
bubbles | false |
cancelable | false |
clickTarget | Specifies whether the slider track or a slider thumb was pressed. |
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. |
keyCode | If the event was triggered by a key press, the keycode for the key. |
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
