分页控件用于浏览多个页面。 我们典型地使用对网页的分页控制，例如博客。 在博客页面的底部，我们可以看到一个矩形区域，作为一个数字列表来指示页面索引，以及一个下一个/上一个按钮来链接到下一个/上一个页面。

创建分页控件

分页控件由页面内容和页面导航区域组成。

创建具有不确定页计数和当前页索引等于零的分页控件

Pagination pagination1 = new Pagination();

要创建一个5页的分页控件，当前页索引等于零

Pagination pagination2 = new Pagination(5);

要创建一个5页的分页控件，当前所选索引等于2

Pagination pagination3 = new Pagination(5, 2);

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Pagination;
import javafx.scene.control.Hyperlink;
import javafx.scene.control.Label;
import javafx.scene.layout.AnchorPane;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;public class Main extends Application {private Pagination pagination;public static void main(String[] args) throws Exception {launch(args);}public int itemsPerPage() {return 8;}public VBox createPage(int pageIndex) {VBox box = new VBox(5);int page = pageIndex * itemsPerPage();for (int i = page; i < page + itemsPerPage(); i++) {VBox element = new VBox();Hyperlink link = new Hyperlink("Item " + (i + 1));link.setVisited(true);Label text = new Label("Search results\nfor " + link.getText());element.getChildren().addAll(link, text);box.getChildren().add(element);}return box;}@Overridepublic void start(final Stage stage) throws Exception {pagination = new Pagination(28, 0);pagination.setStyle("-fx-border-color:red;");pagination.setPageFactory((Integer pageIndex) -> createPage(pageIndex));AnchorPane anchor = new AnchorPane();AnchorPane.setTopAnchor(pagination, 10.0);AnchorPane.setRightAnchor(pagination, 10.0);AnchorPane.setBottomAnchor(pagination, 10.0);AnchorPane.setLeftAnchor(pagination, 10.0);anchor.getChildren().addAll(pagination);Scene scene = new Scene(anchor);stage.setScene(scene);stage.setTitle("PaginationSample");stage.show();}
}

将分段文本添加到分页控件

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Pagination;
import javafx.scene.control.TextArea;
import javafx.scene.layout.AnchorPane;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;public class Main extends Application {private Pagination pagination;final String[] textPages = new String[]{"this is a test 1","this is a test 2","this is a test 3","this is a test 4","this is a test 5","this is a test 6","this is a test 7","this is a test 8","this is a test 8",};public static void main(String[] args) throws Exception {launch(args);}public int itemsPerPage() {return 1;}public VBox createPage(int pageIndex) {VBox box = new VBox(5);int page = pageIndex * itemsPerPage();for (int i = page; i < page + itemsPerPage(); i++) {TextArea text = new TextArea(textPages[i]);text.setWrapText(true);box.getChildren().add(text);}return box;}@Overridepublic void start(final Stage stage) throws Exception {pagination = new Pagination(28, 0);pagination.setPageFactory((Integer pageIndex) -> {if (pageIndex >= textPages.length) {return null;} else {return createPage(pageIndex);}});AnchorPane anchor = new AnchorPane();AnchorPane.setTopAnchor(pagination, 10.0);AnchorPane.setRightAnchor(pagination, 10.0);AnchorPane.setBottomAnchor(pagination, 10.0);AnchorPane.setLeftAnchor(pagination, 10.0);anchor.getChildren().addAll(pagination);Scene scene = new Scene(anchor, 400, 250);stage.setScene(scene);stage.setTitle("PaginationSample");stage.show();}
}

添加未确定大小的内容

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Pagination;
import javafx.scene.control.Label;
import javafx.scene.layout.AnchorPane;
import javafx.scene.layout.VBox;
import javafx.scene.text.Font;
import javafx.stage.Stage;public class Main extends Application {private Pagination pagination;String[] fonts = new String[]{};public static void main(String[] args) throws Exception {launch(args);}public int itemsPerPage() {return 15;}public VBox createPage(int pageIndex) {        VBox box = new VBox(5);int page = pageIndex * itemsPerPage();for (int i = page; i < page + itemsPerPage(); i++) {Label font = new Label(fonts[i]);box.getChildren().add(font);}return box;}@Overridepublic void start(final Stage stage) throws Exception {fonts = Font.getFamilies().toArray(fonts);pagination = new Pagination(fonts.length/itemsPerPage(), 0);pagination.setPageFactory((Integer pageIndex) -> createPage(pageIndex));AnchorPane anchor = new AnchorPane();AnchorPane.setTopAnchor(pagination, 10.0);AnchorPane.setRightAnchor(pagination, 10.0);AnchorPane.setBottomAnchor(pagination, 10.0);AnchorPane.setLeftAnchor(pagination, 10.0);anchor.getChildren().addAll(pagination);Scene scene = new Scene(anchor, 400, 450);stage.setScene(scene);stage.show();}
}
