JavaFx 2.x - Swing :不在FX应用程序线程上
JavaFx 2.x - Swing :不在FX应用程序线程上
提问于 2012-08-30 00:37:04
我正在尝试通过使用附加JFXPanel的JInternalFrame来使用JavaFx 2.x和Swing应用程序
下面是我的代码
public class InternalFrameWithJavafx extends javax.swing.JFrame {
/**
* Creates new form InternalFrameWithJavafx
*/
public InternalFrameWithJavafx() {
initComponents();
final JInternalFrame frame = new JInternalFrame();
frame.setTitle("test InternalFrame");
frame.setVisible(true);
frame.setResizable(true);
frame.setIconifiable(true);
frame.setMaximizable(true);
frame.setIconifiable(true);
frame.setClosable(true);
frame.setSize(800,600);
frame.setLocation(0, 0);
frame.setDefaultCloseOperation(javax.swing.WindowConstants.DISPOSE_ON_CLOSE);
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
final JFXPanel javafxPanel = new JFXPanel();
BorderPane pane = new BorderPane();
javafxPanel.setScene( new Scene(pane) {
Text text = new Text("Hello World");
});
frame.getContentPane().add(javafxPanel, BorderLayout.CENTER);
}
});
this.add(frame);
}
@SuppressWarnings("unchecked")
// <editor-fold defaultstate="collapsed" desc="Generated Code">
private void initComponents() {
setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
getContentPane().setLayout(layout);
layout.setHorizontalGroup(
layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
.addGap(0, 400, Short.MAX_VALUE)
);
layout.setVerticalGroup(
layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
.addGap(0, 300, Short.MAX_VALUE)
);
pack();
}// </editor-fold>
/**
* @param args the command line arguments
*/
public static void main(String args[]) {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (UnsupportedLookAndFeelException e) {
//handle exception
} catch (ClassNotFoundException e) {
//handle exception
} catch (InstantiationException e) {
//handle exception
} catch (IllegalAccessException e) {
//handle exception
}
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
new InternalFrameWithJavafx().setVisible(true);
}
});
}
}我有个例外

请参阅'JavaFX in Swing'教程。您正在执行应在Swing线程(Event Dispatch Thread)上的JavaFX线程上运行的JavaFX操作。
幸运的是，他们从以前的错误中吸取了教训，现在当你在错误的线程上执行操作时，他们会抛出异常。这就是您遇到的异常。
使用该教程中所示的Platform#runLater
Platform.runLater(new Runnable() {
@Override
public void run() {
//javaFX operations should go here
}
});JFXPanel的构造可以保留在EDT上(在该教程中也进行了说明)
