從JavaFX中的按鈕創建一個webview

Question

我有以下簡單的代碼，其中有一個水平方塊，其中有兩個按鈕，其餘部分爲空。現在，我想在用戶按下「當前」按鈕後在免費部分查看Webview。我已經做了類似的事情，但我無法管理佈局，因爲它是Jframe + JavaFX。我想在JavaFx中完全重新構建，因此我想將webview放入jfxPanel（我認爲這是最好的解決方案，其他建議真的很感激）。當我按下按鈕時，我應該看到webview，在這種情況下是當前的，因此我創建了一個句柄。那麼，我該怎麼做？

在此先感謝

下面是一些示例代碼，讓你開始，它創造了幾個網頁視圖和它們之間切換，這取決於一個單選按鈕選擇。

import javafx.application.Application; 
import javafx.geometry.Insets; 
import javafx.scene.Scene; 
import javafx.scene.control.*; 
import javafx.scene.layout.*; 
import javafx.scene.web.WebView; 
import javafx.stage.Stage; 

public class CountThePeople extends Application { 
    private static final String CURRENT_URL = 
     "http://www.census.gov/popclock/"; 
    private static final String PROJECTED_URL = 
     "http://www.sciencedaily.com/releases/2015/08/150810110634.htm"; 

    @Override 
    public void start(final Stage stage) throws Exception { 
     WebView current = new WebView(); 
     current.getEngine().load(CURRENT_URL); 
     WebView projected = new WebView(); 
     projected.getEngine().load(PROJECTED_URL); 

     StackPane viewHolder = new StackPane(); 

     ToggleGroup choice = new ToggleGroup(); 

     RadioButton currentRadio = new RadioButton("Current"); 
     currentRadio.setToggleGroup(choice); 
     RadioButton projectedRadio = new RadioButton("Projected"); 
     projectedRadio.setToggleGroup(choice); 

     choice.selectedToggleProperty().addListener((observable, oldValue, newValue) -> { 
      if (projectedRadio == newValue) { 
       viewHolder.getChildren().setAll(projected); 
      } else { 
       viewHolder.getChildren().setAll(current); 
      } 
     }); 

     choice.selectToggle(currentRadio); 

     VBox layout = new VBox(10, currentRadio, projectedRadio, viewHolder); 
     layout.setPadding(new Insets(10)); 

     stage.setTitle("World Population"); 
     stage.setScene(new Scene(layout)); 
     stage.show(); 
    } 

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