Does Javafx support its own thread?

Question

I wrote a simple Javafx application that launches a new thread, and it works fine with Netbeans. But during compilation, I get the following warning:

explicit use of threads is not supported

Does this mean that now it can work on all possible devices, such as mobile phones or a browser?

Answer 1

JavaFX itself must run in the main JavaFX thread, so starting Thread directly from JavaFX is not currently supported. However, you can create a Java class that spawns Thread. So your JavaFX class calls the Java class, which then runs Thread.

JavaFX Java, JavaFX. , :

import com.sun.javafx.runtime.Entry;
Entry.deferAction( new Runnable() {
                    @Override
                    public void run() {
                        fxListener.onMessage(copy);
                    }
                } );

JavaFX Java. Java, javafx.reflect.
