TabPane是一个GUI组件,使用它可以在单个窗口中加载多个文档。选项卡窗格具有标题区域和内容区域,您可以通过单击各个选项卡的标题在它们之间切换。您可以通过实例化javafx.scene.control.TabPane类来创建选项卡窗格。
选项卡窗格中的每个选项卡均由javafx.scene.control.Tab类表示,您可以分别使用此类的setText()和setContent()方法来设置选项卡的标题和内容。
创建所有必需的选项卡后,需要将它们添加为窗格中的-
tabPane.getTabs().addAll(tab1, tab2);
以下JavaFX程序演示了TabTane的创建。
import java.io.FileInputStream; import java.io.FileNotFoundException; import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.control.Tab; import javafx.scene.control.TabPane; import javafx.scene.image.Image; import javafx.scene.image.ImageView; import javafx.scene.layout.AnchorPane; import javafx.stage.Stage; public class TabPaneExample extends Application { public void start(Stage stage) throws FileNotFoundException { //Creating ImageView object1 Image img1 = new Image(new FileInputStream("D:\\images\\elephant.jpg")); ImageView view1 = new ImageView(img1); view1.setFitWidth(595); view1.setFitHeight(270); //Creating ImageView object2 Image img2 = new Image(new FileInputStream("D:\\images\\boy.jpg")); ImageView view2 = new ImageView(img2); view2.setFitWidth(595); view2.setFitHeight(270); //Creating a TabPane TabPane tabPane = new TabPane(); //Creating the first tab Tab tab1 = new Tab(); //Setting the text tab1.setText("Elephant"); //Setting the content tab1.setContent(view1); //Creating the second tab Tab tab2 = new Tab(); //Setting the text tab2.setText("Boy"); //Setting the content tab2.setContent(view2); //Adding tabs to the tab pane tabPane.getTabs().addAll(tab1, tab2); //Setting anchor pane as the layout AnchorPane pane = new AnchorPane(); AnchorPane.setTopAnchor(tabPane, 15.0); AnchorPane.setRightAnchor(tabPane, 15.0); AnchorPane.setBottomAnchor(tabPane, 15.0); AnchorPane.setLeftAnchor(tabPane, 15.0); pane.getChildren().addAll(tabPane); pane.setStyle("-fx-background-color: BEIGE"); //Setting the stage Scene scene = new Scene(pane, 595, 300); stage.setTitle("Tab Pane"); stage.setScene(scene); stage.show(); } public static void main(String args[]){ launch(args); } }
