Fadeout Cursor in JavaFX After Few Seconds Delay - javafx

Question

On my application(Media Player), when application is in fullscreen mode, I am fading out the top bar and bottom bar. I also wants to fade out the cursor after few seconds delay. I tried FadeTransition, but it take only Node as parameter.
I also tried using thread.
Platform.runLater(new Runnable()
{
#Override
public void run()
{
try
{
Thread.sleep(2000);
scene.setCursor(Cursor.NONE);
}
catch (InterruptedException e)
{
e.printStackTrace();
}
}
});
Here I just wanted to hide the cursor after two seconds delay. It works, but also hang my application for two seconds which I don't expect.
In which way I can fade out the cursor after two seconds delay?

Answer 1

Your code is making the UI hang because you are making a blocking call (Thread.sleep(...)) on the FX Application Thread. If you want to do it that way, you should block on a background thread and schedule the change of the cursor on the FX Application Thread when the pause is complete.
An easier way, though, is just to use a PauseTransition:
PauseTransition pause = new PauseTransition(Duration.seconds(2));
pause.setOnFinished(e -> scene.setCursor(Cursor.NONE));
pause.play();
You can use this as well to make the cursor reappear on when the user does something, and disappear again after 2 seconds:
scene.addEventHandler(MouseEvent.ANY, e -> {
scene.setCursor(Cursor.DEFAULT);
pause.playFromStart();
});
