JavaFX 선 차트에 상황에 맞는 메뉴 추가

Question

내 선 차트를 마우스 오른쪽 버튼으로 클릭 할 때 상황에 맞는 메뉴를 추가하고 싶습니다. 기본적으로 차트의 크기를 조정하기위한 것입니다.이 방법이 있습니까?

Answer 1

다음은 꺾은 선형 차트에서 마우스 오른쪽 버튼을 클릭 할 때 크기 조정 컨텍스트 메뉴를 가져 오는 코드 조각입니다.

final MenuItem resizeItem = new MenuItem("Resize"); 
resizeItem.setOnAction(new EventHandler<ActionEvent>() { 
    @Override public void handle(ActionEvent event) { 
    System.out.println("Resize requested"); 
    } 
}); 

final ContextMenu menu = new ContextMenu(
    resizeItem 
); 

lineChart.setOnMouseClicked(new EventHandler<MouseEvent>() { 
    @Override public void handle(MouseEvent event) { 
    if (MouseButton.SECONDARY.equals(event.getButton())) { 
     menu.show(stage, event.getScreenX(), event.getScreenY()); 
    } 
    } 
});
