Events

Property Detail

page

property

page:Number

The amount the scroll bar value must change to get from one "page" to the next.

If this value is 0, the step value will be used instead. If the step value is 0, paging is not possible.

In the following example, the page is changed to 10:

scrollBar.minimum = 0;
scrollBar.maximum = 100;
scrollBar.step = 1;
scrollBar.page = 10
scrollBar.value = 12;

Implementation
public function get page():Number
public function set page(value:Number):void

Event Detail

change

Event

Event Object Type: starling.events.Event
Event.type property = starling.events.Event.CHANGE

Dispatched when the scroll bar's value changes.

The properties of the event object have the following values:

Property	Value
`bubbles`	false
`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`.
`data`	null
`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.
