Class Pagination

  • All Implemented Interfaces:
    Styleable, EventTarget, Skinnable
    @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.

    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 ten hyperlinks. 

     
   Pagination pagination = new Pagination(10, 0);
   pagination.setPageFactory(new Callback<Integer, Node>() {
       public Node call(Integer pageIndex) {
           VBox box = new VBox(5);
           for (int i = 0; i < pageIndex + 10; i++) {
               Hyperlink link = new Hyperlink(myurls[i]);
               box.getChildren().add(link);
           }
           return box;
       }
   });

    • Property Detail

      • 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.

      • currentPageIndex

        public final IntegerProperty currentPageIndexProperty
        The current page index to display for this pagination control. The first page will be the current page if the value is less than 0. Similarly the last page will be the current page if the value is greater than the pageCount The default is 0 for the first page.

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

      • 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.
