Class Stage

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.

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. When a parent window is closed, all its descendant windows are closed. The same chained behavior applied for a parent window that is iconified. A stage will always be on top of its parent window. 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.Text; 
import javafx.stage.Stage; 

public class HelloWorld extends Application {

    @Override public void start(Stage stage) {
        Scene scene = new Scene(new Group(new Text(25, 25, "Hello World!"))); 

        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.

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

Notes regarding desktop profile implementation.

For desktop profile the runtime will attempt to enter full-screen exclusive mode (FSEM) if such is supported by the platform and it is allowed for this application. If either is not the case a simulated full-screen window will be used instead; the window will be maximized, made undecorated if possible, and moved to the front.

The user can unconditionally exit full-screen mode at any time by pressing ESC.

There are differences in behavior between signed and unsigned applications. Signed applications are allowed to enter full-screen exclusive mode unrestricted while unsigned applications will have the following restrictions:

• Applications can only enter FSEM 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 FSEM in response to ESC key. Attempting to enter FSEM from any other context will result in emulated full-screen mode.

  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 FSEM 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

Method Detail

setScene

public final void setScene(Scene value)

Specify the scene to be used on this stage.

Overrides:

setScene in class Window

show

public final void show()

Description copied from class: Window

Attempts to show this Window by setting visibility to true

Overrides:

show in class Window

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:

void evtHander1() {
     stage1.showAndWait();
     doSomethingAfterStage1Closed(...)
 }

 void evtHander2() {
     stage2.showAndWait();
     doSomethingAfterStage2Closed(...)
 }

 void evtHander3() {
     stage1.hide();
     doSomethingElseHere(...)
 }

 void evtHander4() {
     stage2.hide();
     doSomethingElseHereToo(...)
 }

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.

Throws:

java.lang.IllegalStateException - if this method is called on a thread other than the JavaFX Application Thread.

java.lang.IllegalStateException - if this method is called on the primary stage.

java.lang.IllegalStateException - if this stage is already showing.
