- Property Detail
  - x
```
public final ReadOnlyDoubleProperty xProperty
```
    The horizontal location of this Stage on the screen. Changing this attribute will move the Stage horizontally. Changing this attribute will not visually affect a Stage while fullScreen is true, but will be honored by the Stage once fullScreen becomes false.
    
    See Also:
    
    getX(), setX(double)
  - y
```
public final ReadOnlyDoubleProperty yProperty
```
    The vertical location of this Stage on the screen. Changing this attribute will move the Stage vertically. Changing this attribute will not visually affect a Stage while fullScreen is true, but will be honored by the Stage once fullScreen becomes false.
    
    See Also:
    
    getY(), setY(double)
  - width
```
public final ReadOnlyDoubleProperty widthProperty
```
    The width of this Stage. Changing this attribute will narrow or widen the width of the Stage. Changing this attribute will not visually affect a Stage while fullScreen is true, but will be honored by the Stage once fullScreen becomes false. 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.
    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 Stage. Changing this attribute will shrink or heighten the height of the Stage. Changing this attribute will not visually affect a Stage while fullScreen is true, but will be honored by the Stage once fullScreen becomes false. 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.
    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(), setFocused(boolean)
  - scene
```
public final ReadOnlyObjectProperty<Scene> sceneProperty
```
    The Scene to be rendered on this Stage. There can only be one Scene on the Stage at a time, and a Scene can only be on one Stage at a time. Setting a Scene on a different Stage will cause the old Stage to lose the reference before the new one gains it. You may swap Scenes on a Stage at any time, even while in full-screen exclusive mode. 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 Stage as a value between 0.0 and 1.0. The opacity is reflected across the Stage, 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 Stage with 0% opacity is fully translucent. Typically, a Stage with 0% opacity will not receive any mouse events.
    
    Default value:
    
    1.0
    
    See Also:
    
    getOpacity(), setOpacity(double)
  - onCloseRequest
```
public final ObjectProperty<EventHandler<WindowEvent>> onCloseRequestProperty
```

    getOnHiding(), setOnHiding(EventHandler)
  - onHidden
```
public final ObjectProperty<EventHandler<WindowEvent>> onHiddenProperty
```
    Called just after the Window has been hidden. When the Window is hidden, this event handler is invoked allowing the developer to clean up resources or perform other tasks when the Window is closed.
    
    See Also:
    
    getOnHidden(), setOnHidden(EventHandler)
  - showing
```
public final ReadOnlyBooleanProperty showingProperty
```
    Whether or not this Stage is showing (that is, open on the user's system). The Stage might be "showing", yet the user might not be able to see it due to the Stage being rendered behind another window or due to the Stage 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.

public final void setEventDispatcher(EventDispatcher value)
```
    Sets the value of the property eventDispatcher.
    
    Property description:
    
    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.
  - getEventDispatcher
```
public final EventDispatcher getEventDispatcher()
```
    Gets the value of the property eventDispatcher.
    
    Property description:

  - addEventHandler
```
public final <T extends Event> void addEventHandler(EventType<T> eventType,
                                                    EventHandler<? super T> eventHandler)
```
    Registers an event handler to this node. The handler is called when the node receives an Event of the specified type during the bubbling phase of event delivery.
    
    Type Parameters:
    
    T - the specific event class of the handler
    
    Parameters:
    
    eventType - the type of the events to receive by the handler
    
    eventHandler - the handler to register
    
    Throws:
    
    NullPointerException - if the event type or handler is null
  - removeEventHandler
```
public final <T extends Event> void removeEventHandler(EventType<T> eventType,
                                                       EventHandler<? super T> eventHandler)
```
    Unregisters a previously registered event handler from this node. One handler might have been registered for different event types, so the caller needs to specify the particular event type from which to unregister the handler.
    
    Type Parameters:
    
    T - the specific event class of the handler
    
    Parameters:
    
    eventType - the event type from which to unregister
    
    eventHandler - the handler to unregister
    
    Throws:
    
    NullPointerException - if the event type or handler is null
  - addEventFilter
```
public final <T extends Event> void addEventFilter(EventType<T> eventType,
                                                   EventHandler<? super T> eventFilter)
```
    Registers an event filter to this node. The filter is called when the node receives an Event of the specified type during the capturing phase of event delivery.
    
    Type Parameters:
    
    T - the specific event class of the filter
    
    Parameters:
    
    eventType - the type of the events to receive by the filter
    
    eventFilter - the filter to register
    
    Throws:
    
    NullPointerException - if the event type or filter is null
  - removeEventFilter
```
public final <T extends Event> void removeEventFilter(EventType<T> eventType,
                                                      EventHandler<? super T> eventFilter)
```
    Unregisters a previously registered event filter from this node. One filter might have been registered for different event types, so the caller needs to specify the particular event type from which to unregister the filter.
    
    Type Parameters:
    
    T - the specific event class of the filter
    
    Parameters:
    
    eventType - the event type from which to unregister
    
    eventFilter - the filter to unregister
    
    Throws:
    
    NullPointerException - if the event type or filter is null
  - setEventHandler
```
protected final <T extends Event> void setEventHandler(EventType<T> eventType,
                                                       EventHandler<? super T> eventHandler)
```
    Sets the handler to use for this event type. There can only be one such handler specified at a time. This handler is guaranteed to be called first. This is used for registering the user-defined onFoo event handlers.
    
    Type Parameters:
    
    T - the specific event class of the handler
    
    Parameters:
    
    eventType - the event type to associate with the given eventHandler
    
    eventHandler - the handler to register, or null to unregister
    
    Throws:
    
    NullPointerException - if the event type is null
  - fireEvent
```
public final void fireEvent(Event event)
```
    Fires the specified event.
    This method must be called on the FX user thread.
    
    Parameters:
    
    event - the event to fire
  - buildEventDispatchChain
```
public EventDispatchChain buildEventDispatchChain(EventDispatchChain tail)
```
    Construct an event dispatch chain for this window.
    
    Specified by:
    
    buildEventDispatchChain in interface EventTarget
    
    Parameters:
    
    tail - the initial chain to build from
    
    Returns:
    
    the resulting event dispatch chain for this window
