Resize tabs only when double click on tab name

Question

I have this code which resizes tab when it's clicked twice no matter where I click on the tab.
VBox stackedTitledPanes = createStackedTitledPanes();
   ScrollPane scroll = makeScrollable(stackedTitledPanes);
   final TabPane tabPane = new TabPane();
   final BorderPane mainPane = new BorderPane();
   final Rectangle2D primaryScreenBounds = Screen.getPrimary().getVisualBounds();
  tabPane.setStyle("-fx-font-size: 12pt;"); // Set global size for the font
   // Create Tabs
   Tab tabA = new Tab();
  tabPane.setOnMouseClicked(new EventHandler<MouseEvent>()
   private double sizeX, sizeY;
   private boolean first = true;
   @Override
   public void handle(MouseEvent me)
   if (first)
  sizeX = mainPane.getWidth();
  sizeY = mainPane.getHeight();
  first = false;
   if (me.getButton().equals(MouseButton.PRIMARY) && me.getClickCount() % 2 == 0)
   if (sizeX != mainPane.getWidth() || sizeY != mainPane.getHeight())
  mainPane.setPrefSize(sizeX, sizeY);
   else
  mainPane.setPrefSize(primaryScreenBounds.getWidth(), primaryScreenBounds.getHeight());
  tabA.setText("Main Component");
  tabA.setContextMenu(makeTabContextMenu(tabA, tabPane));  // Set right mouse click menu
   // Add something in Tab
   StackPane tabA_stack = new StackPane();
  tabA_stack.setAlignment(Pos.CENTER);
  tabA_stack.getChildren().add(scroll);
  tabA.setContent(tabA_stack);
  tabPane.getTabs().add(tabA);
   Tab tabB = new Tab();
  tabB.setText("Second Component");
  tabB.setContextMenu(makeTabContextMenu(tabB, tabPane));  // Set right mouse click menu
   // Add something in Tab
   StackPane tabB_stack = new StackPane();
  tabB_stack.setAlignment(Pos.CENTER);
  tabB_stack.getChildren().add(new Label("Label@Tab B"));
  tabB.setContent(tabB_stack);
  tabPane.getTabs().add(tabB);
   Tab tabC = new Tab();
  tabC.setText("Last Component");
  tabC.setContextMenu(makeTabContextMenu(tabC, tabPane));  // Set right mouse click menu
   // Add something in Tab
   StackPane tabC_vBox = new StackPane();
  tabC_vBox.setAlignment(Pos.CENTER);
  tabC_vBox.getChildren().add(new Label("Label@Tab C"));
  tabC.setContent(tabC_vBox);
  tabPane.getTabs().add(tabC);
  mainPane.setCenter(tabPane);
  mainPane.setPrefSize(300, 500);
   //mainPane.setLayoutX(5); // Horizontal Position
  mainPane.setLayoutY(32);   // Vertical Position
  scroll.setPrefSize(395, 580);
  scroll.setLayoutX(5);
  scroll.setLayoutY(32);
Can you tell me how I can modify the code in a way that I can size the tab only when I double click on a tab name?
