javafx.embed.singleThread=true not working

[Hendrik Ebbers]

Thanks!

It’s working now without using private API. Here is the code if someone will have the same problem:

package com.guigarage.masteringcontrols;

import javafx.embed.swing.JFXPanel;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;

import javax.swing.*;
import java.awt.*;

public class JFXPanelDemo1 {

    private static JButton swingButton;
    private static Button jfxButton;

    public static void main(String[] args) {

        final JFXPanel jfxPanel = new JFXPanel();

        SwingUtilities.invokeLater(() -> {
            JFrame swingFrame = new JFrame("Integrate JavaFX in Swing");
            swingFrame.getContentPane().setLayout(new BorderLayout());
            swingButton = new JButton("I'm a Swing button");
            swingFrame.getContentPane().add(BorderLayout.NORTH, swingButton);
            swingButton.addActionListener((e) -> {
                jfxButton.setDisable(!jfxButton.isDisable());
            });

            swingFrame.getContentPane().add(BorderLayout.CENTER, jfxPanel);
            jfxButton = new Button("I'm a JavaFX button");
            StackPane jfxPane = new StackPane(jfxButton);
            Scene jfxScene = new Scene(jfxPane);
            jfxPanel.setScene(jfxScene);
            jfxButton.setOnAction((e) -> {
                swingButton.setEnabled(!swingButton.isEnabled());
            });
            swingFrame.setVisible(true);
        });
    }
}

By the time when JFXPanel constructor is finished, FX has already set up single threaded event dispatching mechanism, so all the subsequent Swing events (including invokeLater() calls) are executed on the right thread.
