This control extends the TrackBase class and is the base class for the HScrollBar and VScrollBar controls.
A scroll bar consists of a track, a variable-size scroll thumb, and two optional arrow buttons. The ScrollBarBase class uses four parameters to calculate its display state:
-
minimum: Minimum range value. -
maximum:Maximum range value. -
value: Current position, which must be within the minimum and maximum range values. - Viewport size: Represents the number of items in the range that you can display at one time. The number of items must be less than or equal to the range, where the range is the set of values between the minimum range value and the maximum range value.

snapInterval:Number[åsidosätt] | Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 4 |
| Körningsmiljöversioner: | Flash Player 10, AIR 1.5 |
The snapInterval property controls the valid values of the value property.
If nonzero, valid values are the sum of the minimum and integer multiples
of this property, for all sums that are less than or equal to the maximum.
For example, if minimum is 10, maximum is 20, and this property is 3, then the
valid values of this Range are 10, 13, 16, 19, and 20.
If the value of this property is zero, then valid values are only constrained to be between minimum and maximum inclusive.
This property also constrains valid values for the stepSize property when set.
If this property is not explicitly set and stepSize is set,
then snapInterval defaults to stepSize.

The VScrollBar and HScrollBar classes override these methods to

use the viewport's scrollPositionDelta methods to compute page and

protected function animatePaging(newValue:Number, pageSize:Number):void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 4 |
| Körningsmiljöversioner: | Flash Player 10, AIR 1.5 |
Animates the operation to move to newValue.
The pageSize parameter is used to compute the amount
of time taken to get to that value, so that the time taken to animate
a paging operation is roughly the same as the non-animated version;
both operations should end up at the same place at about the same time.
Parametrar
newValue:Number — The final value being paged to.
| |
pageSize:Number — The amount of horizontal or vertical movement requested.
This value is used to compute, with the repeatInterval style,
the total time taken to move to the new value. pageSize
is usually set dynamically by the containing Scroller to the value required
to view content at a logical content boundary.

Animates the operation to step to newValue.
The stepSize parameter is used to compute the amount
of time taken to get to that value, so that the time taken to animate
a stepping operation is roughly the same as the non-animated version;
both operations should end up at the same place at about the same time.
Parametrar

| |
stepSize:Number — The amount of stepping requested.
This value is used to compute, with the repeatInterval style,
the total time taken to step to the new value. stepSize
is usually set dynamically by the containing Scroller to the value required

Handles a click on the increment or decrement button of the scroll bar.
This should cause a stepping operation, which is repeated if held down.
The delay before repetition begins and the delay between repeated events
are determined by the repeatDelay and
repeatInterval styles of the underlying Button objects.
