Stage (JavaFX 8)

java.lang.Object
- javafx.stage.Window
- - javafx.stage.Stage

All Implemented Interfaces:

EventTarget
```
public class Stage
extends Window
```
The JavaFX Stage class is the top level JavaFX container. The primary Stage is constructed by the platform. Additional Stage objects may be constructed by the application.
Stage objects must be constructed and modified on the JavaFX Application Thread.

Many of the Stage properties are read only because they can be changed externally by the underlying platform and therefore must not be bindable.

Style

A stage has one of the following styles:
- StageStyle.DECORATED - a stage with a solid white background and platform decorations.
- StageStyle.UNDECORATED - a stage with a solid white background and no decorations.
- StageStyle.TRANSPARENT - a stage with a transparent background and no decorations.
- StageStyle.UTILITY - a stage with a solid white background and minimal platform decorations.
The style must be initialized before the stage is made visible.

On some platforms decorations might not be available. For example, on some mobile or embedded devices. In these cases a request for a DECORATED or UTILITY window will be accepted, but no decorations will be shown.

Owner

A stage can optionally have an owner Window. When a window is a stage's owner, it is said to be the parent of that stage.
Owned Stages are tied to the parent Window. An owned stage will always be on top of its parent window. When a parent window is closed or iconified, then all owned windows will be affected as well. Owned Stages cannot be independantly iconified.
The owner must be initialized before the stage is made visible.
Modality

A stage has one of the following modalities:
- Modality.NONE - a stage that does not block any other window.
- Modality.WINDOW_MODAL - a stage that blocks input events from being delivered to all windows from its owner (parent) to its root. Its root is the closest ancestor window without an owner.
- Modality.APPLICATION_MODAL - a stage that blocks input events from being delivered to all windows from the same application, except for those from its child hierarchy.
When a window is blocked by a modal stage its Z-order relative to its ancestors is preserved, and it receives no input events and no window activation events, but continues to animate and render normally. Note that showing a modal stage does not necessarily block the caller. The show() method returns immediately regardless of the modality of the stage. Use the showAndWait() method if you need to block the caller until the modal stage is hidden (closed). The modality must be initialized before the stage is made visible.

Example:
```
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.text.Font;
import javafx.scene.text.Text;
import javafx.stage.Stage;

public class HelloWorld extends Application {

    @Override public void start(Stage stage) {
        Text text = new Text(10, 40, "Hello World!");
        text.setFont(new Font(40));
        Scene scene = new Scene(new Group(text));

        stage.setTitle("Welcome to JavaFX!");
        stage.setScene(scene);
        stage.sizeToScene();
        stage.show();
    }

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

- Property Detail
  - fullScreen
```
public final ReadOnlyBooleanProperty fullScreenProperty
```
    Specifies whether this Stage should be a full-screen, undecorated window.
    The implementation of full-screen mode is platform and profile-dependent.
    
    When set to true, the Stage will attempt to enter full-screen mode when visible. Set to false to return Stage to windowed mode. An IllegalStateException is thrown if this property is set on a thread other than the JavaFX Application Thread.
    
    The full-screen mode will be exited (and the fullScreen attribute will be set to false) if the full-screen Stage loses focus or if another Stage enters full-screen mode on the same Screen. Note that a Stage in full-screen mode can become invisible without losing its full-screen status and will again enter full-screen mode when the Stage becomes visible.
    If the platform supports multiple screens an application can control which Screen the Stage will enter full-screen mode on by setting its position to be within the bounds of that Screen prior to entering full-screen mode.
    However once in full-screen mode, Stage's x, y, width, and height variables will continue to represent the non-full-screen position and size of the window; the same for iconified, resizable, style, and opacity. If changes are made to any of these attributes while in full-screen mode, upon exiting full-screen mode the Stage will assume those attributes.
    
    In case that more Stage modes are set simultaneously their order of importance is iconified, fullScreen, maximized (from strongest to weakest).
    
    The property is read only because it can be changed externally by the underlying platform and therefore must not be bindable.
    The user can unconditionally exit full-screen mode at any time by pressing ESC.
    There are differences in behavior between applications if a security manager is present. Applications with permissions are allowed to enter full-screen mode unrestricted. Applications without the proper permissions will have the following restrictions:
    - Applications can only enter full-screen mode in response to user input. More specifically, entering is allowed from mouse (Node.mousePressed/mouseReleased/mouseClicked) or keyboard (Node.keyPressed/keyReleased/keyTyped) event handlers. It is not allowed to enter full-screen mode in response to ESC key. Attempting to enter full-screen mode from any other context will be ignored.
      If Stage was constructed as full-screen but not visible it will enter full-screen mode upon becoming visible, with the same limitations to when this is allowed to happen as when setting fullScreen to true.
    - If the application was allowed to enter full-screen mode it will have limited keyboard input. It will only receive KEY_PRESSED and KEY_RELEASED events from the following keys: UP, DOWN, LEFT, RIGHT, SPACE, TAB, PAGE_UP, PAGE_DOWN, HOME, END, ENTER

```
public final ReadOnlyBooleanProperty iconifiedProperty
```
    Defines whether the Stage is iconified or not.
    In case that more Stage modes are set simultaneously their order of importance is iconified} fullScreen, maximized (from strongest to weakest).
    
    On some mobile and embedded platforms setting this property to true will hide the Stage but not show an icon for it.
    
    The property is read only because it can be changed externally by the underlying platform and therefore must not be bindable.

  - alwaysOnTop
```
public final ReadOnlyBooleanProperty alwaysOnTopProperty
```
    Defines whether this Stage is kept on top of other windows.
    If some other window is already always-on-top then the relative order between these windows is unspecified (depends on platform).
    
    There are differences in behavior between applications if a security manager is present. Applications with permissions are allowed to set "always on top" flag on a Stage. In applications without the proper permissions, an attempt to set the flag will be ignored and the property value will be restored to "false".
    
    The property is read only because it can be changed externally by the underlying platform and therefore must not be bindable.

  - resizable
```
public final BooleanProperty resizableProperty
```
    Defines whether the Stage is resizable or not by the user. Programatically you may still change the size of the Stage. This is a hint which allows the implementation to optionally make the Stage resizable by the user.
    Warning: Since 8.0 the property cannot be bound and will throw RuntimeException on an attempt to do so. This is because the setting of resizable is asynchronous on some systems or generally might be set by the system / window manager.
    Bidirectional binds are still allowed, as they don't block setting of the property by the system.

    true

  - showAndWait
```
public void showAndWait()
```
    Shows this stage and waits for it to be hidden (closed) before returning to the caller. This method temporarily blocks processing of the current event, and starts a nested event loop to handle other events. This method must be called on the FX Application thread.
    A Stage is hidden (closed) by one of the following means:
    - the application calls the Window.hide() or close() method on this stage
    - this stage has a non-null owner window, and its owner is closed
    - the user closes the window via the window system (for example, by pressing the close button in the window decoration)
    After the Stage is hidden, and the application has returned from the event handler to the event loop, the nested event loop terminates and this method returns to the caller.
    
    For example, consider the following sequence of operations for different event handlers, assumed to execute in the order shown below:
```
void evtHander1(...) {
     stage1.showAndWait();
     doSomethingAfterStage1Closed(...)
 }

 void evtHander2(...) {
     stage1.hide();
     doSomethingElseHere(...)
 }
```
    evtHandler1 will block at the call to showAndWait. It will resume execution after stage1 is hidden and the current event handler, in this case evtHandler2, returns to the event loop. This means that doSomethingElseHere will execute before doSomethingAfterStage1Closed.
    
    More than one stage may be shown with showAndWait. Each call will start a new nested event loop. The stages may be hidden in any order, but a particular nested event loop (and thus the showAndWait method for the associated stage) will only terminate after all inner event loops have also terminated.
    
    For example, consider the following sequence of operations for different event handlers, assumed to execute in the order shown below:
    evtHandler1 will block at the call to stage1.showAndWait, starting up a nested event loop just like in the previous example. evtHandler2 will then block at the call to stage2.showAndWait, starting up another (inner) nested event loop. The first call to stage1.showAndWait will resume execution after stage1 is hidden, but only after the inner nested event loop started by stage2.showAndWait has terminated. This means that the call to stage1.showAndWait won't return until after evtHandler2 has returned. The order of execution is: stage1.showAndWait, stage2.showAndWait, stage1.hide, doSomethingElseHere, stage2.hide, doSomethingElseHereToo, doSomethingAfterStage2Closed, doSomethingAfterStage1Closed.
    
    This method must not be called on the primary stage or on a stage that is already visible. Additionally, it must either be called from an input event handler or from the run method of a Runnable passed to Platform.runLater. It must not be called during animation or layout processing.
    Throws:
    
    IllegalStateException - if this method is called on a thread other than the JavaFX Application Thread.
    
    IllegalStateException - if this method is called during animation or layout processing.
    
    IllegalStateException - if this method is called on the primary stage.
    
    IllegalStateException - if this stage is already showing.

    Specifies whether this Stage should be a full-screen, undecorated window.
    The implementation of full-screen mode is platform and profile-dependent.
    
    When set to true, the Stage will attempt to enter full-screen mode when visible. Set to false to return Stage to windowed mode. An IllegalStateException is thrown if this property is set on a thread other than the JavaFX Application Thread.
    
    The full-screen mode will be exited (and the fullScreen attribute will be set to false) if the full-screen Stage loses focus or if another Stage enters full-screen mode on the same Screen. Note that a Stage in full-screen mode can become invisible without losing its full-screen status and will again enter full-screen mode when the Stage becomes visible.
    If the platform supports multiple screens an application can control which Screen the Stage will enter full-screen mode on by setting its position to be within the bounds of that Screen prior to entering full-screen mode.
    However once in full-screen mode, Stage's x, y, width, and height variables will continue to represent the non-full-screen position and size of the window; the same for iconified, resizable, style, and opacity. If changes are made to any of these attributes while in full-screen mode, upon exiting full-screen mode the Stage will assume those attributes.
    
    In case that more Stage modes are set simultaneously their order of importance is iconified, fullScreen, maximized (from strongest to weakest).
    
    The property is read only because it can be changed externally by the underlying platform and therefore must not be bindable.
    The user can unconditionally exit full-screen mode at any time by pressing ESC.
    There are differences in behavior between applications if a security manager is present. Applications with permissions are allowed to enter full-screen mode unrestricted. Applications without the proper permissions will have the following restrictions:
    - Applications can only enter full-screen mode in response to user input. More specifically, entering is allowed from mouse (Node.mousePressed/mouseReleased/mouseClicked) or keyboard (Node.keyPressed/keyReleased/keyTyped) event handlers. It is not allowed to enter full-screen mode in response to ESC key. Attempting to enter full-screen mode from any other context will be ignored.
      If Stage was constructed as full-screen but not visible it will enter full-screen mode upon becoming visible, with the same limitations to when this is allowed to happen as when setting fullScreen to true.
    - If the application was allowed to enter full-screen mode it will have limited keyboard input. It will only receive KEY_PRESSED and KEY_RELEASED events from the following keys: UP, DOWN, LEFT, RIGHT, SPACE, TAB, PAGE_UP, PAGE_DOWN, HOME, END, ENTER
    Default value:
    
    false

  - setFullScreenExitKeyCombination
```
public final void setFullScreenExitKeyCombination(KeyCombination keyCombination)
```
    Specifies the KeyCombination that will allow the user to exit full screen mode. A value of KeyCombination.NO_MATCH will not match any KeyEvent and will make it so the user is not able to escape from Full Screen mode. A value of null indicates that the default platform specific key combination should be used.
    An internal copy of this value is made when entering FullScreen mode and will be used to trigger the exit from the mode. If an application does not have the proper permissions, this setting will be ignored.
    
    Parameters:
    
    keyCombination - the key combination to exit on

```
public final void setFullScreenExitHint(String value)
```
    Specifies the text to show when a user enters full screen mode, usually used to indicate the way a user should go about exiting out of full screen mode. A value of null will result in the default per-locale message being displayed. If set to the empty string, then no message will be displayed.
    If an application does not have the proper permissions, this setting will be ignored.
    
    Parameters:
    
    value - the string to be displayed.
    
    Since:
    
    JavaFX 8.0
