Question

我有一个我创建的java swing项目，基本上我将使用JavaFX来简化饼图的创建，以便为用户显示一些数据。我已经通过扩展JFXPanel然后启动并将其添加到swing JFrame中来创建我希望用来实现此目的的类

JFXPanel piePanel = new PieChartSample(test);
contentPane.add(piePanel);
piePanel.setVisible(true);

在这种情况下，test是一个整数的任意数组。

我怀疑问题不是在这里，而是在PieChartSample代码中，虽然这很长并且不太清楚。

public class PieChartSample extends JFXPanel{

ArrayList<Integer> vals;

public PieChartSample(ArrayList<Integer> vals) {
this.vals = vals;
}

private static void initAndShowGUI() {
// This method is invoked on the EDT thread
JPanel frame = new JPanel();
final JFXPanel fxPanel = new JFXPanel();
frame.getContentPane().add(fxPanel);
frame.setSize(500, 500);
frame.setVisible(true);

Platform.runLater(new Runnable() {
    @Override
    public void run() {
        initFX(fxPanel);
    }
   });
}

private static void initFX(JFXPanel fxPanel) {
// This method is invoked on the JavaFX thread
Scene scene = createScene();
fxPanel.setScene(scene);
}

private static Scene createScene() {
Group  root  =  new  Group();
Scene  scene  =  new  Scene(root, Color.ALICEBLUE);
Text  text  =  new  Text();


ObservableList<PieChart.Data> pieChartData =
        FXCollections.observableArrayList(
        new PieChart.Data("%0", 22),
        new PieChart.Data("%20", 13),
        new PieChart.Data("%40", 25),
        new PieChart.Data("%60", 10),
        new PieChart.Data("%80", 22),
        new PieChart.Data("%100", 30));
final PieChart chart = new PieChart(pieChartData);
chart.setTitle("Imported Fruits");

((Group) scene.getRoot()).getChildren().add(chart);

root.getChildren().add(text);

return (scene);
}

public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
    @Override
    public void run() {
        initAndShowGUI();
    }
});
}
}

基本上，当我启动JFrame时，JFXPanel根本不显示。有什么想法吗？

无法将JavaFX框架放入我的swing应用程序中
