Javafx是否支持启动自己的线程？ [英] Does Javafx support starting your own thread?

问题描述

我写了一个简单的Javafx应用程序，它启动了一个新的线程，它可以从Netbeans中运行。
但我在编译期间收到以下警告：

I've wrote a simple Javafx application which starts a new thread and it works OK from Netbeans. But I'm getting following warning during compilation:

explicit use of threads is not supported

这是否意味着它现在可能适用于所有可能的设备，如手机或浏览器？

Does it mean that it might now work in all possible devices like mobile phones or browser?

推荐答案

JavaFX本身必须在主JavaFX线程上运行，因此目前不支持直接从JavaFX启动线程。但是，您可以创建一个生成Thread的Java类。因此，您的JavaFX类调用Java类，然后启动一个Thread。

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

从Java线程回调JavaFX，您需要在主JavaFX线程上。如何执行此操作的示例如下：

Calling back to JavaFX from a Java thread, you need to be on the main JavaFX thread. An example of how to do this is:

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

您不应直接从Java操作JavaFX对象。如果从Java执行，则需要使用javafx.reflect类。

You should not manipulate the JavaFX objects directly from Java. If you do it from Java, you need to use the javafx.reflect classes.
