如何将JNativeHook连接到JavaFX线程？

Question

我正在制作一个具有JavaFX图形用户界面的翻译程序。我正在使用JNativeHook来启用全局keylisteners，当应用程序不在焦点中时。当alt和t同时按下时，程序应该从任务栏中恢复自己。

但是，当我按alt和t时，它会出现一个错误，说明JNativeHook线程不能与javafx线程一起运行。

GlobalScreen.addNativeKeyListener(listener);

                @Override
                public void nativeKeyPressed(NativeKeyEvent nativeKeyEvent) {
                    if(nativeKeyEvent.getKeyCode() == NativeKeyEvent.VC_ALT_L){
                        alt = true;
                    }
                    if(nativeKeyEvent.getKeyCode() == NativeKeyEvent.VC_T){
                        t = true;
                    }

                    check();

                }

                @Override
                public void nativeKeyReleased(NativeKeyEvent nativeKeyEvent) {
                    if(nativeKeyEvent.getKeyCode() == NativeKeyEvent.VC_ALT_L){
                        alt = false;
                    }
                    if(nativeKeyEvent.getKeyCode() == NativeKeyEvent.VC_T){
                        t = false;
                    }
                }

                @Override
                public void nativeKeyTyped(NativeKeyEvent nativeKeyEvent) {

                }
            });

Exception in thread "JNativeHook Dispatch Thread" java.lang.IllegalStateException: Not on FX application thread; currentThread = JNativeHook Dispatch Thread

有没有什么方法可以让JNativeHook线程访问我的javafx线程，以便在程序最小化后用热键重新打开它？

只需将它们包装在platform.runlater中，使它们在FX线程上运行，即：

    Platform.runLater( () -> {
        if(nativeKeyEvent.getKeyCode() == NativeKeyEvent.VC_ALT_L){
            alt = true;
        }
        if(nativeKeyEvent.getKeyCode() == NativeKeyEvent.VC_T){
            t = true;
        }

        check();
    } );
