public class JFXPanel
extends javax.swing.JComponent

JFXPanel is a component to embed JavaFX content into Swing applications. The content to be displayed is specified with the setScene(javafx.scene.Scene) method that accepts an instance of JavaFX Scene. After the scene is assigned, it gets repainted automatically. All the input and focus events are forwarded to the scene transparently to the developer.

There are some restrictions related to JFXPanel. As a Swing component, it should only be accessed from the event dispatch thread, except the setScene(javafx.scene.Scene) method, which can be called either on the event dispatch thread or on the JavaFX application thread.

Here is a typical pattern how JFXPanel can used:

     public class Test {

         private static void initAndShowGUI() {
             // This method is invoked on Swing thread
             JFrame frame = new JFrame("FX");
             final JFXPanel fxPanel = new JFXPanel();
             frame.add(fxPanel);
             frame.setVisible(true);

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

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

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

Constructor Detail

JFXPanel

public JFXPanel()

Creates a new JFXPanel object.

Implementation note: when the first JFXPanel object is created, it implicitly initializes the JavaFX runtime. This is the preferred way to initialize JavaFX in Swing.

Method Detail

getScene

public Scene getScene()

Returns the JavaFX scene attached to this JFXPanel.

Returns:

the Scene attached to this JFXPanel

setScene

public void setScene(Scene newScene)

Attaches a Scene object to display in this JFXPanel. This method can be called either on the event dispatch thread or the JavaFX application thread.

Parameters:

newScene - a scene to display in this JFXpanel

See Also:

EventQueue.isDispatchThread(), Platform.isFxApplicationThread()

setOpaque

public final void setOpaque(boolean opaque)

JFXPanel's opacity is controlled by the JavaFX content which is displayed in this component, so this method overrides JComponent.setOpaque(boolean) to only accept a false value. If this method is called with a true value, no action is performed.

Overrides:

setOpaque in class javax.swing.JComponent

Parameters:

opaque - must be false

isOpaque

public final boolean isOpaque()

JFXPanel's opacity is controlled by the JavaFX content which is displayed in this component, so this method overrides JComponent.isOpaque() to always return a false value.

Overrides:

isOpaque in class javax.swing.JComponent

Returns:

a false value

processMouseEvent

protected void processMouseEvent(java.awt.event.MouseEvent e)

Overrides the Component.processMouseEvent(MouseEvent) method to dispatch the mouse event to the JavaFX scene attached to this JFXPanel.

Overrides:

processMouseEvent in class javax.swing.JComponent

Parameters:

e - the mouse event to dispatch to the JavaFX scene

processMouseMotionEvent

protected void processMouseMotionEvent(java.awt.event.MouseEvent e)

Overrides the Component.processMouseMotionEvent(MouseEvent) method to dispatch the mouse motion event to the JavaFX scene attached to this JFXPanel.

Overrides:

processMouseMotionEvent in class javax.swing.JComponent

Parameters:

e - the mouse motion event to dispatch to the JavaFX scene

processMouseWheelEvent

protected void processMouseWheelEvent(java.awt.event.MouseWheelEvent e)

Overrides the Component.processMouseWheelEvent(MouseWheelEvent) method to dispatch the mouse wheel event to the JavaFX scene attached to this JFXPanel.

Parameters:

e - the component event to dispatch to the JavaFX scene

processHierarchyBoundsEvent

protected void processHierarchyBoundsEvent(java.awt.event.HierarchyEvent e)

Overrides:

addNotify in class javax.swing.JComponent

removeNotify

public void removeNotify()

Notifies this component that it no longer has a parent component. When this method is invoked, any KeyboardActions set up in the the chain of parent components are removed.
