JAVAFX TabPane 的使用方法:
实例1
public class tabPaneTest extends Application {
@Override
public void start(Stage primaryStage) {
primaryStage.setTitle("Tabs");
Group root = new Group();
Scene scene = new Scene(root, 400, 250, Color.WHITE);
TabPane tabPane = new TabPane();
BorderPane borderPane = new BorderPane();
Tab tab = new Tab();
tab.setText("Tab" + i);
HBox hbox = new HBox();
hbox.getChildren().add("tabHome"));
hbox.setAlignment(Pos.CENTER);
tab.setContent(hbox);
tab.setClosable(false);
tabPane.getTabs().add(tab);
tabPane.setSide(Side.LEFT);
tabPane.setSide(Side.RIGHT);
//tabPane.setSide(Side.BOTTOM);
// bind to take available space
borderPane.prefHeightProperty().bind(scene.heightProperty());
borderPane.prefWidthProperty().bind(scene.widthProperty());
borderPane.setCenter(tabPane);
root.getChildren().add(borderPane);
primaryStage.setScene(scene);
primaryStage.show();
}
