JavaFX：在应用程序之前不会显示预加载器

Question

Tutorial I'm following: http://acodigo.blogspot.com/2016/03/javafx-preloader-pantalla-de-carga.html

My preloader doesn't show up before my application when I hit run inside of Eclipse, or when I click on my runnable jar I exported.

Gist: https://gist.github.com/htha9587/d42badd8ff2df0cc1632dbbc19e1ee5e

Could this be one way to make it show up?: I could try adding this method to MainLoader.java:

@Override public void init () throws Exception 
{
    Thread . Sleep (2500); 
}

Any reason why this is happening, and how I can solve It?

Hello I looked over your question if I understand correctly you would like to see the your Preloader screen.

Your thread.sleep() command causes the Preloader also to sleep. If you like to see it you need to add another intensive task like

@Override public void init () throws Exception{
    int COUNT_LIMIT = 40000;
    for (int i = 0; i < COUNT_LIMIT; i++) {
        double progress = (100 * i) / COUNT_LIMIT;
        LauncherImpl.notifyPreloader(this, new Preloader.ProgressNotification(progress));
    }
}

This should do the trick maybe increase COUNT_LIMIT to something that is even higher - maybe (10^10) .
