    JavaFX closable tabs

    974949
      Hello all,

      I've been trying to create a tabpane with closeable tabs, but the close buttons don't appear. I used scene builder, putting in a scene a tabpane and two tabs, settin closeable to true in each one, to no avail.

      Also, I've tried writing it by code:


      Tab tab = new Tab(titulo);
      final ObservableList<Tab> tabs = getTabPane().getTabs();
      tab.setContent(myControl);
      tab.setClosable(true);
      tabs.add(tab);

      With this code, the close button does not appear either. What am I doing wrong?

      Thanks for your help

          Hey,
          they should be closeable by default.
          Have you implemented a TabPane and added the Tabs into the Pane?

          This should work, look at the code and compare to yours. maybe you forgot something small.
          package yourpackage;
          
          import javafx.application.Application;
          import javafx.geometry.Pos;
          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.stage.Stage;
          
          public class AddingTabs extends Application 
          {
              public static void main(String[] args) 
              {
                  Application.launch(args);
              }
          
              @Override
              public void start(Stage primaryStage) 
              {
                  Group root = new Group();
                  Scene scene = new Scene(root, 400, 250, Color.WHITE);
          
                  TabPane tabPane = new TabPane();
          
                  BorderPane borderPane = new BorderPane();
          
                  // generate 10 tabs
                  for (int i = 0; i < 10; 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(hbox);
                      tabPane.getTabs().add(tab);
                  }
                  
                  // add tab pane
                  borderPane.setCenter(tabPane);
          
                  // bind to take available space
                  borderPane.prefHeightProperty().bind(scene.heightProperty());
                  borderPane.prefWidthProperty().bind(scene.widthProperty());
          
                  // add border Pane
                  root.getChildren().add(borderPane);
          
                  primaryStage.setScene(scene);
                  primaryStage.show();
              }
          }

            Hello,

            I've tried your code and, exactly, it works. I reviewed my code and realized the only thing that changed was that I loaded the control containing the tabpane from a scene builder generated pane. So I checked the properties in the controls and found that, by default, TabPane has TabClosingPolicy to UNAVAILABLE, so it wasn't possible to close the tabs.

            Thank you very much :)
