@DefaultProperty("pages") public class Pagination extends Control

A Pagination control is used for navigation between pages of a single content, which has been divided into smaller parts.

## Styling the page indicators

The control can be customized to display numeric page indicators or bullet style indicators by setting the style class `STYLE_CLASS_BULLET`. The `maxPageIndicatorCountProperty` can be used to change the maximum number of page indicators. The property value can also be changed via CSS using `-fx-max-page-indicator-count`. By default, page indicator numbering starts from 1 (corresponding to page index 0).

## Page count

The `pageCountProperty` controls the number of pages this pagination control has. If the page count is not known, `INDETERMINATE` should be used as the page count.

## Page factory

The `pageFactoryProperty` is a callback function that is called when a page has been selected by the application or the user. The function is required for the functionality of the pagination control. The callback function should load and return the contents of the selected page. `null` should be returned if the selected page index does not exist.

## Creating a Pagination control:

A simple example of how to create a pagination control with ten pages and each page containing text.

     Pagination pagination = new Pagination(10, 0);
     pagination.setPageFactory(new Callback<Integer, Node>() {
         @Override
         public Node call(Integer pageIndex) {
             return new Label(pageIndex + 1 + ". Lorem ipsum dolor sit amet,\n"
                          + "consectetur adipiscing elit,\n"
                          + "sed do eiusmod tempor incididunt ut\n"
                          + "labore et dolore magna aliqua.");
         }
     });

or using lambdas

     Pagination pagination = new Pagination(10, 0);
     pagination.setPageFactory(pageIndex ->
             new Label(pageIndex + 1 + ". Lorem ipsum dolor sit amet,\n"
                          + "consectetur adipiscing elit,\n"
                          + "sed do eiusmod tempor incididunt ut\n"
                          + "labore et dolore magna aliqua.");
     );

- ## Property Details

  - ### maxPageIndicatorCount

    public final IntegerProperty maxPageIndicatorCountProperty
    The maximum number of page indicators to use for this pagination control. The maximum number of pages indicators will remain unchanged if the value is less than 1 or greater than the `pageCount`. The number of page indicators will be reduced to fit the control if the `maxPageIndicatorCount` cannot fit. The default is 10 page indicators.
    See Also:
      - `getMaxPageIndicatorCount()`
      - `setMaxPageIndicatorCount(int)`
      - `maxPageIndicatorCountProperty()`

  - ### pageCount

    public final IntegerProperty pageCountProperty
    The number of pages for this pagination control. This value must be greater than or equal to 1. `INDETERMINATE` should be used as the page count if the total number of pages is unknown. The default is an `INDETERMINATE` number of pages.
    See Also:
      - `getPageCount()`
      - `setPageCount(int)`
      - `pageCountProperty()`

  - ### currentPageIndex

    public final IntegerProperty currentPageIndexProperty

    Because the page indicators set the current page index, the currentPageIndex property permits only bidirectional binding. The `bind` method throws an UnsupportedOperationException.

    See Also:
      - `getCurrentPageIndex()`
      - `setCurrentPageIndex(int)`
      - `currentPageIndexProperty()`

  - ### pageFactory

    public final ObjectProperty<Callback<Integer,Node>> pageFactoryProperty
    The pageFactory callback function that is called when a page has been selected by the application or the user. This function is required for the functionality of the pagination control. The callback function should load and return the contents the page index. Null should be returned if the page index does not exist. The currentPageIndex will not change when null is returned. The default is null if there is no page factory set.
