Class Window

  • All Implemented Interfaces:
    EventTarget
    Direct Known Subclasses:
    PopupWindow, Stage

    public class Window
extends Object
implements EventTarget
    A top level window within which a scene is hosted, and with which the user interacts. A Window might be a Stage, PopupWindow, or other such top level. A Window is used also for browser plug-in based deployments.

    Window objects must be constructed and modified on the JavaFX Application Thread.

    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.

    • Property Detail

      • outputScaleX

        public final ReadOnlyDoubleProperty outputScaleXProperty
        The scale that the Window will apply to horizontal scene coordinates in all stages of rendering and compositing the output to the screen or other destination device. This property is updated asynchronously by the system at various times including:
        • Window creation
        • At some point during moving a window to a new Screen which may be before or after the Screen property is updated.
        • In response to a change in user preferences for output scaling.

      • outputScaleY

        public final ReadOnlyDoubleProperty outputScaleYProperty
        The scale that the Window will apply to vertical scene coordinates in all stages of rendering and compositing the output to the screen or other destination device. This property is updated asynchronously by the system at various times including:
        • Window creation
        • At some point during moving a window to a new Screen which may be before or after the Screen property is updated.
        • In response to a change in user preferences for output scaling.

      • forceIntegerRenderScale

        public final BooleanProperty forceIntegerRenderScaleProperty
        Boolean property that controls whether only integer render scales are set by default by the system when there is a change in the associated output scale. The renderScale properties will be updated directly and simultaneously with any changes in the associated outputScale properties, but the values can be overridden by subsequent calls to the setRenderScale setters or through appropriate use of binding. This property will not prevent setting non-integer scales directly using the renderScale property object or the convenience setter method.
        Default value:
        false
        Since:
        9
        See Also:
        isForceIntegerRenderScale(), setForceIntegerRenderScale(boolean)

      • renderScaleX

        public final DoubleProperty renderScaleXProperty
        The horizontal scale that the Window will use when rendering its Scene to the rendering buffer. This property is automatically updated whenever there is a change in the outputScaleX property and can be overridden either by calling setRenderScaleX() in response to a listener on the outputScaleX property or by binding it appropriately.
        Default value:
        outputScaleX
        Since:
        9
        See Also:
        getRenderScaleX(), setRenderScaleX(double)

      • renderScaleY

        public final DoubleProperty renderScaleYProperty
        The vertical scale that the Window will use when rendering its Scene to the rendering buffer. This property is automatically updated whenever there is a change in the outputScaleY property and can be overridden either by calling setRenderScaleY() in response to a listener on the outputScaleY property or by binding it appropriately.
        Default value:
        outputScaleY
        Since:
        9
        See Also:
        getRenderScaleY(), setRenderScaleY(double)

      • x

        public final ReadOnlyDoubleProperty xProperty
        The horizontal location of this Window on the screen. Changing this attribute will move the Window horizontally. If this Window is an instance of Stage, changing this attribute will not visually affect the Window while fullScreen is true, but will be honored by the Window once fullScreen becomes false.
        See Also:
        getX(), setX(double)

      • y

        public final ReadOnlyDoubleProperty yProperty
        The vertical location of this Window on the screen. Changing this attribute will move the Window vertically. If this Window is an instance of Stage, changing this attribute will not visually affect the Window while fullScreen is true, but will be honored by the Window once fullScreen becomes false.
        See Also:
        getY(), setY(double)

      • width

        public final ReadOnlyDoubleProperty widthProperty
        The width of this Window. Changing this attribute will narrow or widen the width of the Window. This value includes any and all decorations which may be added by the Operating System such as resizable frame handles. Typical applications will set the Scene width instead. This Window will take its width from the scene if it has never been set by the application. Resizing the window by end user does not count as a setting the width by the application. If this Window is an instance of Stage, changing this attribute will not visually affect the Window while fullScreen is true, but will be honored by the Window once fullScreen becomes false.

        The property is read only because it can be changed externally by the underlying platform and therefore must not be bindable.

        See Also:
        getWidth(), setWidth(double)

      • height

        public final ReadOnlyDoubleProperty heightProperty
        The height of this Window. Changing this attribute will shrink or heighten the height of the Window. This value includes any and all decorations which may be added by the Operating System such as the title bar. Typical applications will set the Scene height instead. This window will take its height from the scene if it has never been set by the application. Resizing this window by end user does not count as a setting the height by the application. If this Window is an instance of Stage, changing this attribute will not visually affect the Window while fullScreen is true, but will be honored by the Window once fullScreen becomes false.

        The property is read only because it can be changed externally by the underlying platform and therefore must not be bindable.

        See Also:
        getHeight(), setHeight(double)

      • focused

        public final ReadOnlyBooleanProperty focusedProperty
        Whether or not this Window has the keyboard or input focus.

        The property is read only because it can be changed externally by the underlying platform and therefore must not be bindable.

        See Also:
        isFocused()

      • scene

        public final ReadOnlyObjectProperty<Scene> sceneProperty
        The Scene to be rendered on this Window. There can only be one Scene on the Window at a time, and a Scene can only be on one Window at a time. Setting a Scene on a different Window will cause the old Window to lose the reference before the new one gains it. You may swap Scenes on a Window at any time, even if it is an instance of Stage and with fullScreen set to true. If the width or height of this Window have never been set by the application, setting the scene will cause this Window to take its width or height from that scene. Resizing this window by end user does not count as setting the width or height by the application. An IllegalStateException is thrown if this property is set on a thread other than the JavaFX Application Thread.
        Default value:
        null
        See Also:
        getScene(), setScene(Scene)

      • opacity

        public final DoubleProperty opacityProperty
        Defines the opacity of the Window as a value between 0.0 and 1.0. The opacity is reflected across the Window, its Decoration and its Scene content. On a JavaFX runtime platform that does not support opacity, assigning a value to this variable will have no visible difference. A Window with 0% opacity is fully translucent. Typically, a Window with 0% opacity will not receive any mouse events.
        Default value:
        1.0
        See Also:
        getOpacity(), setOpacity(double)

      • showing

        public final ReadOnlyBooleanProperty showingProperty
        Whether or not this Window is showing (that is, open on the user's system). The Window might be "showing", yet the user might not be able to see it due to the Window being rendered behind another Window or due to the Window being positioned off the monitor.
        Default value:
        false
        See Also:
        isShowing()

      • eventDispatcher

        public final ObjectProperty<EventDispatcher> eventDispatcherProperty
        Specifies the event dispatcher for this node. The default event dispatcher sends the received events to the registered event handlers and filters. When replacing the value with a new EventDispatcher, the new dispatcher should forward events to the replaced dispatcher to maintain the node's default event handling behavior.

        Convenience method for setting a single Object property that can be retrieved at a later date. This is functionally equivalent to calling the getProperties().put(Object key, Object value) method. This can later be retrieved by calling getUserData().
        Parameters:
        value - The value to be stored - this can later be retrieved by calling getUserData().
        Since:
        JavaFX 8u40

      • getUserData

        public Object getUserData​()
        Returns a previously set Object property, or null if no such property has been set using the setUserData(java.lang.Object) method.
        Returns:
        The Object that was previously set, or null if no property has been set or if null was set.

      • setScene

        protected void setScene​(Scene value)
        Sets the value of the property scene.
        Property description:
        The Scene to be rendered on this Window. There can only be one Scene on the Window at a time, and a Scene can only be on one Window at a time. Setting a Scene on a different Window will cause the old Window to lose the reference before the new one gains it. You may swap Scenes on a Window at any time, even if it is an instance of Stage and with fullScreen set to true. If the width or height of this Window have never been set by the application, setting the scene will cause this Window to take its width or height from that scene. Resizing this window by end user does not count as setting the width or height by the application. An IllegalStateException is thrown if this property is set on a thread other than the JavaFX Application Thread.
        Default value:
        null
