JavaFX: Issue with setting same Node to multiple tabs
javafx-2, tabs
Solution
In JavaFX, each `Node` can have exactly one (1) `Parent`. See the Node Class Page in the JavaFX API. If you add a `Node` to another `Parent`, the `Node` looses its "connection" with the old `Parent`, which means it will not be displayed or accessable under the old `Parent`. The method which causes this in your source code is `tab.setContent(myText);`.
To solve your problem, you have to create five different (=separate) objects and set each one of them to exactly one `TabPane` as child // content .
Problem
I am trying to set a particular node to more than one tabs on a tab pane. The problem is that only the last tab has the node when the application is launched but the rest of the tabs are shown empty. I am attaching the code and a few screen shots to explain the problem: ``` import javafx.application.Application; import javafx.geometry.Pos; import javafx.geometry.Side; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.control.Label; import javafx.scene.control.Tab; import javafx.scene.control.TabPane; import javafx.scene.layout.BorderPane; import javafx.scene.layout.HBox; import javafx.scene.paint.Color; import javafx.scene.text.Text; import javafx.stage.Stage; public class TabExample extends Application { public static void main(String[] args) { Application.launch(args); } @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(); Text myText = new Text("Hello"); for (int i = 0; i < 5; i++) { Tab tab = new Tab(); tab.setText("Tab" + i); HBox hbox = new HBox(); hbox.getChildren().add(new Label("Tab" + i)); hbox.setAlignment(Pos.CENTER); tab.setContent(myText); tab.setClosable(false); tabPane.getTabs().add(tab); } 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(); } } ``` Please let me know if there is anything wrong with what I am doing or is it a known bug?
