All Implemented Interfaces:
EventTarget
@DefaultProperty("root") public class Scene extends Object implements EventTarget
The JavaFX Scene class is the container for all content in a scene graph. The background of the scene is filled as specified by the fill property.

The application must specify the root Node for the scene graph by setting the root property. If a Group is used as the root, the contents of the scene graph will be clipped by the scene's width and height and changes to the scene's size (if user resizes the stage) will not alter the layout of the scene graph. If a resizable node (layout Region or Control) is set as the root, then the root's size will track the scene's size, causing the contents to be relayed out as necessary.

The scene's size may be initialized by the application during construction. If no size is specified, the scene will automatically compute its initial size based on the preferred size of its content. If only one dimension is specified, the other dimension is computed using the specified dimension, respecting content bias of a root.

An application may request depth buffer support or scene anti-aliasing support at the creation of a Scene. A scene with only 2D shapes and without any 3D transforms does not need a depth buffer nor scene anti-aliasing support. A scene containing 3D shapes or 2D shapes with 3D transforms may use depth buffer support for proper depth sorted rendering; to avoid depth fighting (also known as Z fighting), disable depth testing on 2D shapes that have no 3D transforms. See depthTest for more information. A scene with 3D shapes may enable scene anti-aliasing to improve its rendering quality.

The depthBuffer and antiAliasing flags are conditional features. With the respective default values of: false and SceneAntialiasing.DISABLED. See ConditionalFeature.SCENE3D for more information.

A default headlight will be added to a scene that contains one or more Shape3D nodes, but no light nodes. This light source is a Color.WHITE PointLight placed at the camera position.

A Scene may be created and modified on any thread until it is attached to a Window that is showing. After that, it must be modified only on the JavaFX Application Thread. Note that Scene is not thread-safe; modifying a Scene on multiple threads at the same time will lead to unpredictable results and must be avoided.

The JavaFX Application Thread is created as part of the startup process for the JavaFX runtime. See the Application class and the Platform.startup(Runnable) method for more information.

Example:

import javafx.scene.*;
import javafx.scene.paint.*;
import javafx.scene.shape.*;

Group root = new Group();
Scene s = new Scene(root, 300, 300, Color.BLACK);

Rectangle r = new Rectangle(25,25,250,250);
r.setFill(Color.BLUE);

root.getChildren().add(r);

  • Method Details

    • addPreLayoutPulseListener

      public final void addPreLayoutPulseListener(Runnable r)
      Adds a new scene pre layout pulse listener to this scene. Every time a pulse occurs, this listener will be called on the JavaFX Application Thread directly before the CSS and layout passes, and also before any rendering is done for this frame. This scene pulse listener is suitable for knowing when a scenegraph pulse is happening and also for modifying the scenegraph (as it is called before CSS and layout, so any changes made will be properly styled and positioned). This method must be called on the JavaFX Application thread.
      Parameters:
      r - The Runnable to be called when the pulse occurs.
      Throws:
      IllegalStateException - if this method is called on a thread other than the JavaFX Application Thread.
      NullPointerException - if the provided Runnable is null.
      Since:
      9

    • removePreLayoutPulseListener

      public final void removePreLayoutPulseListener(Runnable r)
      Removes a previously registered scene pre layout pulse listener from listening to pulses in this scene. This method does nothing if the specified Runnable is not already in the list. This method must be called on the JavaFX Application thread.
      Parameters:
      r - The Runnable that should no longer be called when the pulse occurs for this scene.
      Throws:
      IllegalStateException - if this method is called on a thread other than the JavaFX Application Thread.
      Since:
      9

    • addPostLayoutPulseListener

      public final void addPostLayoutPulseListener(Runnable r)
      Adds a new scene post layout pulse listener to this scene. Every time a pulse occurs, this listener will be called on the JavaFX Application Thread directly after the CSS and layout passes, but before any rendering is done for this frame. This scene pulse listener is suitable for knowing when a scenegraph pulse is happening, but it is not suited to use cases related to modifying the scenegraph (as it is called after CSS and layout, so any changes will possibly be incorrect until the next pulse is run). An alternative (and better) solution for situations where a scenegraph modification is required to happen is to use either the addPreLayoutPulseListener(Runnable) API or the the AnimationTimer API. This method must be called on the JavaFX Application thread.
      Parameters:
      r - The Runnable to be called when the pulse occurs.
      Throws:
      IllegalStateException - if this method is called on a thread other than the JavaFX Application Thread.
      NullPointerException - if the provided Runnable is null.
      Since:
      9

    • removePostLayoutPulseListener

      public final void removePostLayoutPulseListener(Runnable r)
      Removes a previously registered scene post layout pulse listener from listening to pulses in this scene. This method does nothing if the specified Runnable is not already in the list. This method must be called on the JavaFX Application thread.
      Parameters:
      r - The Runnable that should no longer be called when the pulse occurs for this scene.
      Throws:
      IllegalStateException - if this method is called on a thread other than the JavaFX Application Thread.
      Since:

    • setFill

      public final void setFill(Paint value)
      Sets the value of the fill property.
      Property description:
      Defines the background fill of this Scene. Both a null value meaning 'paint no background' and a Paint with transparency are supported. The default fill of the Scene is Color.WHITE, but it is more commonly the case that the initial color shown to users is the background fill of the root node of the Scene, as it typically is stretched to take up all available space in the Scene. The root node of the Scene is given the CSS style class 'root', and the default user agent stylesheets that ship with JavaFX (presently Caspian and Modena) apply styling on to this root style class. In the case of Caspian this does not impact the background fill color of the root node, but in the case of Modena the default fill is set to be a light gray color.
      Default value:
      WHITE
      Parameters:
      value - the value for the fill property

      Sets the value of the root property.
      Property description:
      Defines the root Node of the scene graph. If a Group is used as the root, the contents of the scene graph will be clipped by the scene's width and height and changes to the scene's size (if user resizes the stage) will not alter the layout of the scene graph.

    • snapshot

      public WritableImage snapshot(WritableImage image)
      Takes a snapshot of this scene and returns the rendered image when it is ready. CSS and layout processing will be done for the scene prior to rendering it. The entire destination image is cleared using the fill Paint of this scene. The nodes in the scene are then rendered to the image. The point (0,0) in scene coordinates is mapped to (0,0) in the image. If the image is smaller than the size of the scene, then the rendering will be clipped by the image.

      When taking a snapshot of a scene that is being animated, either explicitly by the application or implicitly (such as chart animation), the snapshot will be rendered based on the state of the scene graph at the moment the snapshot is taken and will not reflect any subsequent animation changes.

      Parameters:
      image - the writable image that will be used to hold the rendered scene. It may be null in which case a new WritableImage will be constructed. If the image is non-null, the scene will be rendered into the existing image. In this case, the width and height of the image determine the area that is rendered instead of the width and height of the scene.
      Returns:
      the rendered image
      Throws:
      IllegalStateException - if this method is called on a thread other than the JavaFX Application Thread.
      Since:
      JavaFX 2.2

    • snapshot

      public void snapshot(Callback<SnapshotResult,Void> callback, WritableImage image)
      Takes a snapshot of this scene at the next frame and calls the specified callback method when the image is ready. CSS and layout processing will be done for the scene prior to rendering it. The entire destination image is cleared using the fill Paint of this scene. The nodes in the scene are then rendered to the image. The point (0,0) in scene coordinates is mapped to (0,0) in the image. If the image is smaller than the size of the scene, then the rendering will be clipped by the image.

      This is an asynchronous call, which means that other events or animation might be processed before the scene is rendered. If any such events modify a node in the scene that modification will be reflected in the rendered image (as it will also be reflected in the frame rendered to the Stage).

      When taking a snapshot of a scene that is being animated, either explicitly by the application or implicitly (such as chart animation), the snapshot will be rendered based on the state of the scene graph at the moment the snapshot is taken and will not reflect any subsequent animation changes.

      Parameters:
      callback - a class whose call method will be called when the image is ready. The SnapshotResult that is passed into the call method of the callback will contain the rendered image and the source scene that was rendered. The callback parameter must not be null.
      image - the writable image that will be used to hold the rendered scene. It may be null in which case a new WritableImage will be constructed. If the image is non-null, the scene will be rendered into the existing image. In this case, the width and height of the image determine the area that is rendered instead of the width and height of the scene.
      Throws:
      IllegalStateException - if this method is called on a thread other than the JavaFX Application Thread.
      NullPointerException - if the callback parameter is null.
      Since:
      JavaFX 2.2

    • lookup

      public Node lookup(String selector)
      Looks for any node within the scene graph based on the specified CSS selector. If more than one node matches the specified selector, this function returns the first of them. If no nodes are found with this id, then null is returned.
      Parameters:
      selector - The css selector to look up
      Returns:
      the Node in the scene which matches the CSS selector, or null if none is found.

    • getStylesheets

      public final ObservableList<String> getStylesheets()
      Gets an observable list of string URLs linking to the stylesheets to use with this scene's contents.

      The URL is a hierarchical URI of the form [scheme:][//authority][path]. If the URL does not have a [scheme:] component, the URL is considered to be the [path] component only. Any leading '/' character of the [path] is ignored and the [path] is treated as a path relative to the root of the application's classpath.

      The RFC 2397 "data" scheme for URLs is supported in addition to the protocol handlers that are registered for the application. If a URL uses the "data" scheme and the MIME type is either empty, "text/plain", or "text/css", the payload will be interpreted as a CSS file. If the MIME type is "application/octet-stream", the payload will be interpreted as a binary CSS file (see Stylesheet.convertToBinary(File, File)). 

      

 package com.example.javafx.app;

 import javafx.application.Application;
 import javafx.scene.Group;
 import javafx.scene.Scene;
 import javafx.stage.Stage;

 public class MyApp extends Application {

      public final String getUserAgentStylesheet()
      Get the URL of the user-agent stylesheet that will be used by this Scene. If the URL has not been set, the platform-default user-agent stylesheet will be used.

      For additional information about using CSS with the scene graph, see the CSS Reference Guide.

      Returns:
      The URL of the user-agent stylesheet that will be used by this Scene, or null if has not been set.
      Since:
      JavaFX 8u20

    • setUserAgentStylesheet

      public final void setUserAgentStylesheet(String url)
      Set the URL of the user-agent stylesheet that will be used by this Scene in place of the the platform-default user-agent stylesheet. If the URL does not resolve to a valid location, the platform-default user-agent stylesheet will be used.

      The URL is a hierarchical URI of the form [scheme:][//authority][path]. If the URL does not have a [scheme:] component, the URL is considered to be the [path] component only. Any leading '/' character of the [path] is ignored and the [path] is treated as a path relative to the root of the application's classpath.
