Hi, I’m currently trying the experimental support of the javafx.embed.singleThread flag to mix the EDT and JFX Application Thread. Therefore I created a demo application. But when I start the app the following exception is thrown: Exception in thread "AWT-EventQueue-0" java.lang.IllegalStateException: Not on FX application thread; currentThread = AWT-EventQueue-0
I think I’m doing something wrong but currently I have no idea why this is not working. Any ideas? I’m using the folioing JavaFX version: java version "1.8.0-ea" Java(TM) SE Runtime Environment (build 1.8.0-ea-b123) Java HotSpot(TM) 64-Bit Server VM (build 25.0-b65, mixed mode) Here is the code of the demo application: public class JFXPanelDemo1 { private static JButton swingButton; private static Button jfxButton; public static void main(String[] args) { 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()); }); JFXPanel jfxPanel = new JFXPanel(); 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); } ); } }
