Method Detail

runLater

public static void runLater(java.lang.Runnable runnable)

Run the specified Runnable on the JavaFX Application Thread at some unspecified time in the future. This method, which may be called from any thread, will post the Runnable to an event queue and then return immediately to the caller. The Runnables are executed in the order they are posted. A runnable passed into the runLater method will be executed before any Runnable passed into a subsequent call to runLater.

Parameters:

runnable - the Runnable whose run method will be executed on the JavaFX Application Thread

isFxApplicationThread

public static boolean isFxApplicationThread()

Returns true if the calling thread is the JavaFX Application Thread. Use this call the ensure that a given task is being executed (or not being executed) on the JavaFX Application Thread.

Returns:

true if running on the JavaFX Application Thread

exit

public static void exit()

Causes the JavaFX application to terminate. If this method is called after the Application start method is called, then the JavaFX launcher will call the Application stop method and terminate the JavaFX application thread. The launcher thread will then shutdown. If there are no other non-daemon threads that are running, the Java VM will exit. If this method is called from the Preloader or the Application init method, then the Application stop method may not be called.

Note: if the application is embedded in a browser, then this method may have no effect.

setImplicitExit

public static void setImplicitExit(boolean implicitExit)

Sets the implicitExit attribute to the specified value. If this attribute is true, the JavaFX runtime will implicitly shutdown when the last window is closed; the JavaFX launcher will call the Application.stop() method and terminate the JavaFX application thread. If this attribute is false, the application will continue to run normally even after the last window is closed, until the application calls exit(). The default value is true.

Parameters:

implicitExit - a flag indicating whether or not to implicitly exit when the last window is closed.

Since:

2.2

isImplicitExit

public static boolean isImplicitExit()

Gets the value of the implicitExit attribute.

Returns:

the implicitExit attribute

Since:

2.2

isSupported

public static boolean isSupported(ConditionalFeature feature)

Queries whether a specific conditional feature is supported by the platform.

For example:

 // Query whether filter effects are supported
 if (Platform.isSupported(ConditionalFeature.EFFECT)) {
    // use effects
 }
 

Parameters:

feature - the conditional feature in question.
