# Class SwingNode

java.lang.Object
javafx.scene.Node
com.sun.javafx.scene.AbstractNode
javafx.embed.swing.SwingNode

All Implemented Interfaces:
  `Styleable`, `EventTarget`

public class SwingNode extends com.sun.javafx.scene.AbstractNode
This class is used to embed a Swing content into a JavaFX application. The content to be displayed is specified with the `setContent(javax.swing.JComponent)` method that accepts an instance of Swing `JComponent`. The hierarchy of components contained in the `JComponent` instance should not contain any heavyweight components, otherwise `SwingNode` may fail to paint it. The content gets repainted automatically. All the input and focus events are forwarded to the `JComponent` instance transparently to the developer.

Here is a typical pattern which demonstrates how `SwingNode` can be used:

         public class SwingFx extends Application {

             @Override
             public void start(Stage stage) {
                 final SwingNode swingNode = new SwingNode();
                 createAndSetSwingContent(swingNode);

                 StackPane pane = new StackPane();
                 pane.getChildren().add(swingNode);

                 stage.setScene(new Scene(pane, 100, 50));
                 stage.show();
             }

             private void createAndSetSwingContent(final SwingNode swingNode) {
                 SwingUtilities.invokeLater(new Runnable() {
                     @Override
                     public void run() {
                         swingNode.setContent(new JButton("Click me!"));
                     }
                 });
             }

             public static void main(String[] args) {
                 launch(args);
             }
         }

Since:
  JavaFX 8.0

- ## Constructor Details

  - ### SwingNode

    public SwingNode()
    Constructs a new instance of `SwingNode`.

- ## Method Details

  - ### setContent

    public void setContent(JComponent content)
    Attaches a `JComponent` instance to display in this `SwingNode`.

    The method can be called either on the JavaFX Application thread or the Event Dispatch thread. Note however, that access to a Swing component must occur from the Event Dispatch thread according to the Swing threading restrictions.

    Parameters:
      `content` - a Swing component to display in this `SwingNode`
    See Also:
      - `EventQueue.isDispatchThread()`
      - `Platform.isFxApplicationThread()`

  - ### getContent

    public JComponent getContent()
    Returns the `JComponent` instance attached to this `SwingNode`.

    The method can be called either on the JavaFX Application thread or the Event Dispatch thread. Note however, that access to a Swing component must occur from the Event Dispatch thread according to the Swing threading restrictions.

    Returns:
      the Swing component attached to this `SwingNode`
    See Also:
      - `EventQueue.isDispatchThread()`
      - `Platform.isFxApplicationThread()`

  - ### resize

    public void resize(double width, double height)
    Invoked by the `SwingNode`'s parent during layout to set the `SwingNode`'s width and height. Applications should not invoke this method directly. If an application needs to directly set the size of the `SwingNode`, it should set the Swing component's minimum/preferred/maximum size constraints which will be propagated correspondingly to the `SwingNode` and it's parent will honor those settings during layout.
    Overrides:
      `resize` in class `Node`
    Parameters:
      `width` - the target layout bounds width
      `height` - the target layout bounds height

      - `Node.maxWidth(double)`
      - `Node.maxHeight(double)`
      - `Node.getLayoutBounds()`

  - ### prefWidth

    Returns the `SwingNode`'s maximum width for use in layout calculations. This value corresponds to the maximum width of the Swing component.
    Overrides:
      `maxWidth` in class `Node`
    Parameters:
      `height` - the height that should be used if maximum width depends on it

    Returns the `SwingNode`'s maximum height for use in layout calculations. This value corresponds to the maximum height of the Swing component.
    Overrides:
      `maxHeight` in class `Node`
    Parameters:
      `width` - the width that should be used if maximum height depends on it
    Returns:
      the maximum height that the node should be resized to during layout
    See Also:
      - `Node.isResizable()`
      - `Node.getContentBias()`

  - ### minWidth

    public double minWidth(double height)
    Returns the `SwingNode`'s minimum width for use in layout calculations. This value corresponds to the minimum width of the Swing component.
    Overrides:
      `minWidth` in class `Node`
    Parameters:
