JavaFX Script被拋棄以后，很久不關(guān)心JavaFX了，偶然發(fā)現(xiàn)JavaFX已經(jīng)發(fā)展到2.2，而且已經(jīng)綁定到JDK7中，看來(lái)Oracle對(duì)它還是蠻重視的。
看到有人在論壇提問(wèn)TWaver有沒(méi)有JavaFX版本，于是去Oracle網(wǎng)站上逛了一下，發(fā)現(xiàn)可以將JavaFX集成進(jìn)Swing程序中，真是福音啊，立馬動(dòng)手寫了個(gè)Demo，集成起來(lái)還是很方便的。
運(yùn)行效果
代碼分析
窗體中間是個(gè)很典型的Network，上下各是一個(gè)JavaFX容器，上面容器中包含一個(gè)Slider，滑動(dòng)時(shí)可以改變TWaver選中Node的RenderColor，下面的容器中包含一些Text，選中Network中的Node并拖動(dòng)的時(shí)候在Text組件上顯示Node的name和location。
在這個(gè)Demo里，程序架構(gòu)還是Swing，JavaFX提供了一個(gè)名為JFXPanel的組件可以嵌入到Swing容器中，JFXPanel內(nèi)可以放JavaFX的組件，需要注意，Swing和JavaFX的線程不同，官方的原文是："JavaFX data should be accessed only on the JavaFX User thread","Swing data should be changed only on the EDT"，所以如果要在Swing中修改JavaFX的數(shù)據(jù)，應(yīng)該使用Platform#runLater包裝，本例中，拖動(dòng)Node時(shí)修改JavaFX的Text組件的相關(guān)代碼：
1 network.getDataBox().addElementPropertyChangeListener(new PropertyChangeListener() {
2 @Override
3 public void propertyChange(PropertyChangeEvent evt) {
4 if("location".equals(evt.getPropertyName())){
5 Element element= (Element) evt.getSource();
6 final String name=element.getName();
7 final double x=element.getX();
8 final double y=element.getY();
9 Platform.runLater(new Runnable() {
10 @Override
11 public void run() {
12 nameText.setText(name);
13 locationText.setText("X:"+x+" Y:"+y);
14 }
15 });
16 }
17 }
18 });
同樣，如果要在JavaFX中修改Swing數(shù)據(jù)，也要用SwingUtilities#invokeLater包裝，本例中，滑動(dòng)Slider修改選中Node的Render Color代碼如下：
1 slider.valueProperty().addListener(new ChangeListener<Number>() {
2 public void changed(ObservableValue<? extends Number> ov,
3 Number old_val,final Number new_val) {
4 SwingUtilities.invokeLater(new Runnable() {
5 @Override
6 public void run() {
7 Iterator it=network.getSelectionModel().selection();
8 while (it.hasNext()){
9 Element element= (Element) it.next();
10 element.putRenderColor(new java.awt.Color(new_val.intValue()));
11 }
12 }
13 });
14 }
15 });
最后附上全部代碼：

2 static TNetwork network;

4 static Text locationText;
5 static Slider slider;
