Question

我有以下简单代码，其中有一个水平块，其中有两个按钮，剩余部分为空。现在，我想在用户按下＆＃34; current＆＃34;之后在免费部分内查看Webview。按钮。我已经做了类似的事情，但我无法管理布局，因为它是一个Jframe + JavaFX。我想在JavaFx中完全重新构建，因此我想将webview放在jfxPanel中（我认为它是最好的解决方案，其他任何建议都非常感谢）。我按下按钮时会看到webview，在这种情况下是当前的，因此我创建了一个句柄。那么，我该怎么做呢？

提前致谢

以下是一些示例代码，可以帮助您入门，它会创建一些WebView并根据选择的单选按钮在它们之间切换。

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);
    }
}
