As part of Swing/FX interoperability efforts, a new JavaFX node should be created to embed Swing content into JavaFX applications. Following is the proposed API:

public class SwingNode extends Node {
  /**
    * Attaches a {@code JComponent} instance to display in this {@code SwingNode}.
    * <p>
    * The method can be called either on the JavaFX Application thread or the Swing thread.
    * Note however, that access to a Swing component must occur from the Swing thread according
    * to the Swing threading restrictions.
    *
    * @param content a Swing component to display in this {@code SwingNode}
    *
    * @see java.awt.EventQueue#isDispatchThread()
    * @see javafx.application.Platform#isFxApplicationThread()
    */
   public void setContent(final JComponent content);

  /**
    * Returns the {@code JComponent} instance attached to this {@code SwingNode}.
    * <p>
    * The method can be called either on the JavaFX Application thread or the Swing thread.
    * Note however, that access to a Swing component must occur from the Swing thread according
    * to the Swing threading restrictions.
    *
    * @see java.awt.EventQueue#isDispatchThread()
    * @see javafx.application.Platform#isFxApplicationThread()
    *
    * @return the Swing component attached to this {@code SwingNode}
    */
   public JComponent getContent();
}
