关于java：双击时调整JavaFX选项卡的大小

Resize JavaFX tab when double click

我用JavaFX选项卡做了一个简单的例子：

public class test extends Application
{

private BorderPane root;

// Navigation Utilization
private ActionTabs actiontabs;

@Override
public void start(Stage primaryStage)
{

// Set Main Window Label
primaryStage.setTitle("Desktop Client");
Image iv = new Image(getClass().getResource("/images/internet-icon.png").toExternalForm());
primaryStage.getIcons().add(iv);

root = new BorderPane();
root.setLeft(getLeftHBox(primaryStage, root));
Scene scene = new Scene(root, 1000, 1000, Color.WHITESMOKE); // Set main Stage color

primaryStage.setScene(scene);

Rectangle2D primaryScreenBounds = Screen.getPrimary().getVisualBounds();

// Set Stage boundaries to visible bounds of the main screen
primaryStage.setX(primaryScreenBounds.getMinX());
primaryStage.setY(primaryScreenBounds.getMinY());
primaryStage.setWidth(primaryScreenBounds.getWidth()); // Maximum width of the display
primaryStage.setHeight(primaryScreenBounds.getHeight()); // Maximum height of the display
primaryStage.show();

}

public static void main(String[] args)
{
launch(args);
}

private HBox getLeftHBox(Stage primaryStage, BorderPane root)
{
HBox hbox = new HBox();

TabPane tabPane = new TabPane();
BorderPane mainPane = new BorderPane();

tabPane.setStyle("-fx-font-size: 12pt;"); // Set global size for the font
// Create Tabs
Tab tabA = new Tab();
tabA.setText("Main Component");
tabA.setStyle("-fx-font-size: 12pt;"); // Set size of the tab name
tabA.setClosable(false);
// Add something in Tab
StackPane tabA_stack = new StackPane();
tabA_stack.setAlignment(Pos.CENTER);
tabA_stack.getChildren().add(new Label("Label@Tab A"));
tabA.setContent(tabA_stack);
tabPane.getTabs().add(tabA);

Tab tabB = new Tab();
tabB.setText("Second Component");
tabB.setStyle("-fx-font-size: 12pt;"); // Set size of the tab name
tabB.setClosable(false);
// 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.setStyle("-fx-font-size: 12pt;"); // Set size of the tab name
tabC.setClosable(false); // da se mahne opciqta da se zatvarq tab
// 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

hbox.getChildren().addAll(mainPane);

return hbox;
}

}

我想当我双击一个选项卡名称时，最大化选项卡主体的大小，使其与应用程序的大小具有相同的宽度和高度。类似于Eclipse IDE选项卡。JavaFX有可能做到这一点吗？

编辑

这是我测试过的代码。

public BorderPane initNavigation(Stage primaryStage)
{

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());
//mainPane.toFront();
}
}
}
});

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);

return mainPane;
}

问题是，当我双击选项卡名称时，如何用选项卡代码覆盖该阶段？
