Constructor detail

JScrollBar

()

constructor

public function JScrollBar(orientation:int, value:int = 0, extent:int = 10, min:int = 0, max:int = 100)

JScrollBar(orientation:Number, value:Number, extent:Number, min:Number, max:Number)
JScrollBar(orientation:Number) default to value=0, extent=10, min=0, max=100

Creates a scrollbar with the specified orientation, value, extent, minimum, and maximum. The "extent" is the size of the viewable area. It is also known as the "visible amount".

Note: Use setBlockIncrement to set the block increment to a size slightly smaller than the view's extent. That way, when the user jumps the knob to an adjacent position, one or two lines of the original contents remain in view. Parameters

	`orientation:int` — the scrollbar's orientation to either VERTICAL or HORIZONTAL.

	`value:int` (default = `0`)

	`extent:int` (default = `10`)

	`min:int` (default = `0`)

	`max:int` (default = `100`)

addStateListener

()

method

public function addStateListener(listener:Function, priority:int = 0, useWeakReference:Boolean = false):void

Adds a listener to listen the scrollBar's state change event.

Parameters

getBlockIncrement

()

method

public function getBlockIncrement():int

Returns the amount to change the scrollbar's value by, given a block (usually "page") up/down request. A ScrollBarUI implementation typically calls this method when the user clicks above or below the scrollbar "knob" to change the value up or down by large amount. Subclasses my override this method to compute a value, e.g. the change required to scroll up or down one paragraph in a text document.

The JScrollPane component creates scrollbars (by default) that then set the block increment by the viewport, if it has one. The {

Returns

int — the block increment

Returns the amount to change the scrollbar's value by, given a unit up/down request. A ScrollBarUI implementation typically calls this method when the user clicks on a scrollbar up/down arrow and uses the result to update the scrollbar's value. Subclasses my override this method to compute a value, e.g. the change required to scroll up or down one (variable height) line text or one row in a table.

The JScrollPane component creates scrollbars (by default) that then set the unit increment by the viewport, if it has one. The {

Event detail

stateChanged

event

Event object type: org.aswing.event.InteractiveEvent
InteractiveEvent.type property = org.aswing.event.InteractiveEvent.STATE_CHANGED

Dispatched when the scrollBar's state changed.

The InteractiveEvent.STATE_CHANGED constant defines the value of the type property of the event object for a stateChanged event.

The properties of the event object have the following values:

Property	Value
`bubbles`	false
`cancelable`	false
`isProgrammatic()`	True means this event is fired by the programmatic reason, false means user mouse/keyboard interaction reason.
`currentTarget`	The Object that defines the event listener that handles the event. For example, if you use `comp.addEventListener()` to register an event listener, comp is the value of the `currentTarget`.
`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.

Constant detail

HORIZONTAL

constant

public static const HORIZONTAL:int = 0

Horizontal orientation.

VERTICAL

constant
