How to show context menu in FlowPane body - javafx-2

Question

I have a FlowPane which use used as stage for many BorderPane components. I created Context menu for the BorderPane components. I want to add second context menu also for the FlowPane but it turns out that I now have two context menus when I click on BorderPane. I need a way to exclude the second context menu from the BorderPane.
FlowPane flow;
public ScrollPane infrastructurePane()
{
flow = new FlowPane();
flow.setPadding(new Insets(5, 5, 5, 5));
flow.setVgap(15);
flow.setHgap(15);
flow.setAlignment(Pos.CENTER);
ScrollPane scroll = new ScrollPane();
scroll.setStyle("-fx-background-color:transparent;");
Rectangle2D primaryScreenBounds = Screen.getPrimary().getVisualBounds();
scroll.setPrefSize(primaryScreenBounds.getWidth(), primaryScreenBounds.getHeight());
scroll.setHbarPolicy(ScrollPane.ScrollBarPolicy.AS_NEEDED); // Horizontal scroll bar
scroll.setVbarPolicy(ScrollPane.ScrollBarPolicy.AS_NEEDED); // Vertical scroll bar
scroll.setContent(flow);
scroll.viewportBoundsProperty().addListener(new ChangeListener<Bounds>()
{
#Override
public void changed(ObservableValue<? extends Bounds> ov, Bounds oldBounds, Bounds bounds)
{
flow.setPrefWidth(bounds.getWidth());
flow.setPrefHeight(bounds.getHeight());
}
});
//flow.setPrefWrapLength(170); // preferred width allows for two columns
flow.setStyle("-fx-background-color: white;");
for (int i = 0; i < 28; i++)
{
flow.getChildren().add(generatePanel(flow));
}
scroll = makeTabContextMenu(scroll);
String cssURL = "/com/dx57dc/css/ButtonsDemo.css";
String css = this.getClass().getResource(cssURL).toExternalForm();
flow.getStylesheets().add(css);
return scroll;
}
public BorderPane generatePanel(FlowPane flow)
{
HBox thb = new HBox();
thb.setPadding(new Insets(10, 10, 10, 10));
thb.setStyle("-fx-background-color: #006699;");
HBox bhb = new HBox();
bhb.setPadding(new Insets(10, 10, 10, 10));
bhb.setStyle("-fx-background-color: #B0B0B0;");
DropShadow ds = new DropShadow();
ds.setOffsetY(3.0);
ds.setOffsetX(3.0);
ds.setColor(Color.GRAY);
BorderPane bp = new BorderPane();
bp.setEffect(ds);
bp.setCache(true);
bp.setPrefSize(320, 180);
bp.setMaxSize(320, 180);
bp.setId("app");
bp.setStyle("-fx-background-color: linear-gradient(to bottom, #f2f2f2, #d4d4d4);"

bp.setTop(thb);
bp.setBottom(bhb);

Is there a way to show makeTabContextMenu() only visible for the FlowPane body?

Answer 1

Have you tried to set the event consumed?
#Override
public void handle(MouseEvent t)
{
...
t.consume()
...
}
